DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claims 229-232, 247-254, and 256-270 are pending.
Status of the Application
Applicant’s response and amendment filed 07 October 2025 are acknowledged and entered.
Applicant has amended Claims 229, 232, 254, and 257-260. Applicant has added Claims 261-270.
Response to Amendment
Objections to the claims are withdrawn.
Applicant has amended the claims to overcome the 103 rejections; the 103 rejections are withdrawn.
The NSDP rejections are maintained.
Claims 229-232, 247-254, and 256-270 are examined.
Arguments applicable to newly applied rejections to amended or newly presented claims are addressed below. Arguments that are no longer relevant are not addressed.
Rejections not reiterated here are withdrawn.
Claim Interpretation
It is noted that Claims 269-270 (which depend from Claim 264, 248, and 232) are composition claims directed to a kit that comprise instructions for performing a method. The kit includes instructions for performing a method but those instructions do not add change the structure of the composition recited in Claim 232 and therefore do not provide any patentable weight to composition claims. Applicant should note that methods to any kind of treatment or methods of treating any deafness, any hearing loss, any vision loss, any Usher syndrome type III, or any retinitis pigmentosa are not enabled.
Double Patenting
The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969).
A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).
The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.
The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer.
Claims 229-232, 247-254, and 256-270 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-28 of the U.S. Patent No. 11807867 (“US867”) in view of WO900, Powell, App178, and US952. This rejection is maintained and updated in response to the claim amendments. All supporting references are of record.
Although the claims at issue are not identical, they are directed to overlapping subject matter because the instant claims recite a composition comprising an AAV nucleic acid vector wherein the vector comprises a 5’ ITR, a CMV enhancer, a CBA promoter, a chimeric intron according to SEQ ID NO 16, a 5’UTR, a coding sequence (CDS) encoding a CLRN1 protein according to SEQ ID NO 3, a 3’UTR, a polyA signal, and a 3’ITR, wherein the CDS comprises a nt sequence spanning 2 consecutive exons of CLRN1 genomic DNA and lacks an intron sequence between them; wherein the composition can comprise other components such as SEQ ID NOs 17 or 20; to the composition comprising an excipient; to an AAV2 capsid comprising the composition, to an Anc80 capsid comprising the composition; to a kit comprising the composition; and to methods of introducing it to a cochlea of a mammal that can be a human who can have been previously identified as having a defective endogenous CLRN1 gene; to methods of increasing CLRN1 expression in the ear or eye; and to methods of treating hearing or vision loss.
The US867 claims are drawn to a plurality of recombinant AAV vectors: a first vector comprising a nucleic acid sequence of SEQ ID NO 96 and a second vector comprising a nucleic acid sequence of SEQ ID NO 105 (US867), wherein each of the vectors is encapsulated by an AAV capsid having a certain serotype, wherein the capsid can be an AAV2 capsid or an Anc80 capsid; to a composition comprising the vectors, wherein the composition can be formulated for intra-cochlear administration, to a method of expressing a recombinant full-length otoferlin protein in a mammalian cell, and/or to methods of treating hearing loss by administering the vectors into the cochlea of a subject.
Both claim sets are directed to AAV vectors for treating hearing loss in a mammal or human by administering the vector to the cochlea of the mammal/human.
An artisan would not know what is US867 SEQ ID NO 96 so they would consult the US867 Spec. and SEQ listing and find (Col 184 L59-67; Col 185-195) SEQ ID NO 96 comprises two ITRs (a 5’ ITR and a 3’ITR), a CAG promoter comprising: a CMV enhancer, chicken β-actin gene sequence, and a chimeric intron. US867 SEQ ID NO 96 comprises claimed SEQ ID NOs 16 and 17 as shown by the following alignments:

Therefore the patented US867 claims recite elements (i), (ii), (iii), (iv), and (ix) of the claimed invention. Then the other prior art teaches the other claim elements that the US867 claims do not recite:
WO900 (¶99) teaches an rAAV vector comprising the CLRN1 cDNA including the 5’ and 3’UTRs, and teaches driving it with the chicken β-actin promoter. WO900 teaches (¶9-10) the polynucleotide (polynt) can include a sequence having SEQ ID NO 2 (which it specifies comprises a 5’UTR and 3’UTR) and can be included on a vector that can be an adeno-associated viral vector (AAV) that can be used for transfecting ocular cells or cells of the inner ear. WO900 teaches (¶21) that the heterologous polynucleotide comprised in the AAV vector is flanked by at least one, and generally by two AAV inverted terminal repeat sequence (ITRs); an artisan would realize that being flanked by two ITRs refers to one ITR on either side, which is a 5’ITR and a 3’ITR. WO900 teaches (¶10-11) treating retinal cells.
WO900 SEQ ID NO 2 comprises a polynt comprising a sequence encoding the amino acid sequence of instant SEQ ID NO 3 (which has been back-translated from AA[Wingdings font/0xE0]nucleotides). This is shown by the following sequence alignment:

XX
CC The present invention relates to a method for generating cell clones with
CC stable transgene (Gene Of Interest (GOI)) expression. The method of the
CC invention comprises: (i) inactivation of endogenous essential genes of
CC cell substrate through Gene Inactivation Cassettes (GIC), (ii) trans-
CC complementation of essential gene products through Gene Supplementary
CC Cassettes (GSC), alternatively, the cassette codes for the gene product
CC that is capable of inactivating GIC function, (iii) the GOI expression
CC cassettes are preferably, physically linked to GSC to take advantage of
CC favourable selective pressure, (iv) GIC could be preferably physically
CC linked to GSC and GOI expression cassettes, where the endogenous
CC essential genes of cell substrate refer to genes or combination of genes
CC that are essential for cell survival and / or cell proliferation. The GIC
CC comprises a vector comprising a promoter operably linked to RNA
CC interference, RNAi (shRNA) / dsRNA / ribozyme molecule, or tandem repeats
CC of such transcript units, targeted to cell endogenous essential mRNA. The
CC invention provides strategies for increasing the productivity of
CC recombinant protein expression in isogenic cell-lines, and a novel
CC selection system for the improved stability and homogeneity of transgene
CC expression in isogenic cells without dependence on continuous selective
CC drugs. An example of the invention provides an essential gene knock-down
CC cassette, targeted at 3' UTR of human endogenous Yes1 gene, and a
CC supplementary Yes1 expression cassette which uses a 3' UTR from bovine
CC growth hormone (BGH) polyA. The present sequence is a bovine growth
CC hormone (BGH) polyA Yes1 supplementary expression cassette 3' UTR, used
CC in an example of the invention. Note: This version of SEQ ID 30 is given
CC in example 3, but it is not the same as the sequence referred to as SEQ
CC ID 30 (seeAXQ61560) in the sequence listing.

It would have been obvious to an artisan before the effective filing date of the claimed invention to modify the invention of the US867 claims with the sequence encoding CLRN1 of WO900 and the teachings about a polyA sequence of Powell and App178 for the benefits of using the US867 vectors to treat Usher syndrome and to increase transgene expression. One would have been motivated to do so with a reasonable expectation of success because Powell teaches that a bovine growth hormone polyA signal can increase transgene expression. One would have been motivated to do so with a reasonable expectation of success because WO900 teaches (¶3-4) expressing CLRN1 had known usage in treating Usher syndrome, including (¶11) for both hearing and vision losses, and it would have been a simple matter to swap the sequence encoding CLRN1 of WO900 for the sequence encoding otoferlin of the US867 claims. An artisan would know that they need only use one AAV vector to encode CLRN1 because WO900 teaches (¶99, 108-111) the entire mCLRN1 cDNA was placed on a single AAV vector, indicating the entire CLRN1 cDNA could fit on a single AAV vector. They would have been motivated to use a single vector because it is simpler to administer a single vector gene therapy than a dual vector gene therapy.
US952 teaches (Col 11 L3-15) a kit that comprises nucleic acid compounds within a container of solution and that the kit can comprise a pre-loaded syringe comprising the compounds. An artisan would have put their compounds into a kit comprising a pre-loaded syringe for the benefit of ensuring that the recipient has the exact dosage ready to administer and because doing so would have prevented any complications that arise from mixing a solution and then getting the mixed solution into a syringe.
Therefore the instant claims would have been obvious in view of the US867 claims, WO900, Powell, App178, and US952.
Claims 229-232, 247-254, and 256-270 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-25 of US Patent No. 12077773 (“US773”) in view of WO900, Powell, App178, and US952. This rejection is maintained and updated in response to the claim amendments. All supporting references are of record.
Although the claims at issue are not identical, they are directed to overlapping subject matter because the instant claims recite a composition comprising an AAV nucleic acid vector wherein the vector comprises a 5’ ITR, a CMV enhancer, a CBA promoter, a chimeric intron according to SEQ ID NO 16, a 5’UTR, a coding sequence (CDS) encoding a CLRN1 protein according to SEQ ID NO 3, a 3’UTR, a polyA signal, and a 3’ITR, wherein the CDS comprises a nt sequence spanning 2 consecutive exons of CLRN1 genomic DNA and lacks an intron sequence between them; wherein the composition can comprise other components such as SEQ ID NOs 17 or 20; to the composition comprising an excipient; to an AAV2 capsid comprising the composition, to an Anc80 capsid comprising the composition; to a kit comprising the composition; and to methods of introducing it to a cochlea of a mammal that can be a human who can have been previously identified as having a defective endogenous CLRN1 gene; to methods of increasing CLRN1 expression in the ear or eye; and to methods of treating hearing or vision loss.
The US773 claims are drawn to a plurality of recombinant AAV vectors: a first vector comprising a 5’ITR, a 3’ITR, a CAG promoter comprising the CMV enhancer of SEQ ID NO 98, a chicken β-actin gene sequence, and the chimeric intron of SEQ ID NO 100 and a second vector, wherein each of the vectors is encapsulated by an AAV capsid having a certain serotype, wherein the AAV vector can be an AAV2 or an Anc80; to a composition comprising the vectors, wherein the composition can be formulated for intra-cochlear administration.
Both claim sets are directed to AAV vectors for administering a gene therapy to the cochlea.
An artisan would not know what are US773 SEQ ID NOs 98 and 100 so they would consult the US773 Spec. and SEQ listing and find (Col 184 L59-67; Col 185-195) SEQ ID NO 98 comprises a CMV enhancer and SEQ ID NO 100 comprises a chimeric intron. US773 SEQ ID NO 100 comprises claimed SEQ ID NO 16 and US773 SEQ ID NO 98 comprises claimed SEQ ID NO 17 as shown by the following alignments:

Therefore the patented US773 claims recite elements (i), (ii), (iii), (iv), and (ix) of the claimed invention. Then the other prior art teaches the other claim elements that the US773 claims do not recite:
WO900 teaches (¶99) an rAAV vector comprising the CLRN1 cDNA including the 5’ and 3’UTRs, and teaches driving it with the chicken β-actin promoter. WO900 teaches (¶9-10) the polynucleotide (polynt) can include a sequence having SEQ ID NO 2 (which it specifies comprises a 5’UTR and 3’UTR) and can be included on a vector that can be an adeno-associated viral vector (AAV) that can be used for transfecting ocular cells or cells of the inner ear. WO900 teaches (¶21) that the heterologous polynucleotide comprised in the AAV vector is flanked by at least one, and generally by two AAV inverted terminal repeat sequence (ITRs); an artisan would realize that being flanked by two ITRs refers to one ITR on either side, which is a 5’ITR and a 3’ITR. WO900 teaches (¶10-11) treating retinal cells.
WO900 SEQ ID NO 2 comprises a polynt comprising a sequence encoding the amino acid sequence of instant SEQ ID NO 3 (which has been back-translated from AA[Wingdings font/0xE0]nucleotides). This is shown by the following sequence alignment:

CC The present invention relates to a method for generating cell clones with
CC stable transgene (Gene Of Interest (GOI)) expression. The method of the
CC invention comprises: (i) inactivation of endogenous essential genes of
CC cell substrate through Gene Inactivation Cassettes (GIC), (ii) trans-
CC complementation of essential gene products through Gene Supplementary
CC Cassettes (GSC), alternatively, the cassette codes for the gene product
CC that is capable of inactivating GIC function, (iii) the GOI expression
CC cassettes are preferably, physically linked to GSC to take advantage of
CC favourable selective pressure, (iv) GIC could be preferably physically
CC linked to GSC and GOI expression cassettes, where the endogenous
CC essential genes of cell substrate refer to genes or combination of genes
CC that are essential for cell survival and / or cell proliferation. The GIC
CC comprises a vector comprising a promoter operably linked to RNA
CC interference, RNAi (shRNA) / dsRNA / ribozyme molecule, or tandem repeats
CC of such transcript units, targeted to cell endogenous essential mRNA. The
CC invention provides strategies for increasing the productivity of
CC recombinant protein expression in isogenic cell-lines, and a novel
CC selection system for the improved stability and homogeneity of transgene
CC expression in isogenic cells without dependence on continuous selective
CC drugs. An example of the invention provides an essential gene knock-down
CC cassette, targeted at 3' UTR of human endogenous Yes1 gene, and a
CC supplementary Yes1 expression cassette which uses a 3' UTR from bovine
CC growth hormone (BGH) polyA. The present sequence is a bovine growth
CC hormone (BGH) polyA Yes1 supplementary expression cassette 3' UTR, used
CC in an example of the invention. Note: This version of SEQ ID 30 is given
CC in example 3, but it is not the same as the sequence referred to as SEQ
CC ID 30 (seeAXQ61560) in the sequence listing.

A poly-A sequence comprising SEQ ID NO 20 is component (viii) of the instant claims.
It would have been obvious to an artisan before the effective filing date of the claimed invention to modify the invention of the US773 claims with the sequence encoding CLRN1 of WO900 and the teachings about a polyA sequence of Powell and App178 for the benefits of using the US773 vectors to treat Usher syndrome and to increase transgene expression. One would have been motivated to do so with a reasonable expectation of success because Powell teaches that a bovine growth hormone polyA signal can increase transgene expression. One would have been motivated to do so with a reasonable expectation of success because WO900 teaches (¶3-4) expressing CLRN1 had known usage in treating Usher syndrome, including (¶11) for both hearing and vision losses, and it would have been a simple matter to swap the sequence encoding CLRN1 of WO900 for the sequence encoding otoferlin of the US773 claims. An artisan would know that they need only use one AAV vector to encode CLRN1 because WO900 teaches (¶99, 108-111) the entire CLRN1 cDNA was placed on a single AAV vector, indicating the entire CLRN1 cDNA could fit on a single AAV vector. They would have been motivated to use a single vector because it is simpler to administer a single vector gene therapy than a dual vector gene therapy.
US952 teaches (Col 11 L3-15) a kit that comprises nucleic acid compounds within a container of solution and that the kit can comprise a pre-loaded syringe comprising the compounds. An artisan would have put their compounds into a kit comprising a pre-loaded syringe for the benefit of ensuring that the recipient has the exact dosage ready to administer and because doing so would have prevented any complications that arise from mixing a solution and then getting the mixed solution into a syringe.
Therefore the instant claims would have been obvious in view of the US773 claims, WO900, Powell, App178, and US952.
Claims 229-232, 247-254, and 256-270 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-26 of the U.S. Patent No. 12305191 (“US191”) in view of WO900, Powell, App178, and US952. This rejection is maintained and updated in response to the claim amendments. All supporting references are of record.
Although the claims at issue are not identical, they are directed to overlapping subject matter because the instant claims recite a composition comprising an AAV nucleic acid vector wherein the vector comprises a 5’ ITR, a CMV enhancer, a CBA promoter, a chimeric intron according to SEQ ID NO 16, a 5’UTR, a coding sequence (CDS) encoding a CLRN1 protein according to SEQ ID NO 3, a 3’UTR, a polyA signal, and a 3’ITR, wherein the CDS comprises a nt sequence spanning 2 consecutive exons of CLRN1 genomic DNA and lacks an intron sequence between them; wherein the composition can comprise other components such as SEQ ID NOs 17 or 20; to the composition comprising an excipient; to an AAV2 capsid comprising the composition, to an Anc80 capsid comprising the composition; to a kit comprising the composition; and to methods of introducing it to a cochlea of a mammal that can be a human who can have been previously identified as having a defective endogenous CLRN1 gene; to methods of increasing CLRN1 expression in the ear or eye; and to methods of treating hearing or vision loss.
The US191 claims are drawn to a plurality of recombinant AAV vectors: a first vector comprising a 5’ITR, a 3’ITR, a CAG promoter comprising SEQ ID NO 61, and a second vector, wherein each of the vectors is encapsulated by an AAV capsid having a certain serotype, wherein the capsid can be an AAV2 capsid or an Anc80 capsid; to a composition comprising the vectors, wherein the composition can be formulated for intra-cochlear administration.
Both claim sets are directed to AAV vectors for administering a gene therapy to the cochlea.
An artisan would not know what is US191 SEQ ID NO 61 so they would consult the US191 Spec. and SEQ listing and find (Col 81 L30-35; Col 184 L10-20) SEQ ID NO 61 comprises a CAG promoter comprising: a CMV enhancer, chicken β-actin gene sequence, and a chimeric intron. US191 SEQ ID NO 61 comprises claimed SEQ ID NOs 16 and 17 as shown by the following alignments:

Therefore the patented US191 claims recite elements (i), (ii), (iii), (iv), and (ix) of the claimed invention. Then the other prior art teaches the other claim elements that the US191 claims do not recite:
WO900 teaches (¶99) an rAAV vector comprising the CLRN1 cDNA including the 5’ and 3’UTRs, and teaches driving it with the chicken β-actin promoter. WO900 teaches (¶9-10) the polynucleotide (polynt) can include a sequence having SEQ ID NO 2 (which it specifies comprises a 5’UTR and 3’UTR) and can be included on a vector that can be an adeno-associated viral vector (AAV) that can be used for transfecting ocular cells or cells of the inner ear. WO900 teaches (¶21) that the heterologous polynucleotide comprised in the AAV vector is flanked by at least one, and generally by two AAV inverted terminal repeat sequence (ITRs); an artisan would realize that being flanked by two ITRs refers to one ITR on either side, which is a 5’ITR and a 3’ITR. WO900 teaches (¶10-11) treating retinal cells.
WO900 SEQ ID NO 2 comprises a polynt comprising a sequence encoding the amino acid sequence of instant SEQ ID NO 3 (which has been back-translated from AA[Wingdings font/0xE0]nucleotides). This is shown by the following sequence alignment:

CC The present invention relates to a method for generating cell clones with
CC stable transgene (Gene Of Interest (GOI)) expression. The method of the
CC invention comprises: (i) inactivation of endogenous essential genes of
CC cell substrate through Gene Inactivation Cassettes (GIC), (ii) trans-
CC complementation of essential gene products through Gene Supplementary
CC Cassettes (GSC), alternatively, the cassette codes for the gene product
CC that is capable of inactivating GIC function, (iii) the GOI expression
CC cassettes are preferably, physically linked to GSC to take advantage of
CC favourable selective pressure, (iv) GIC could be preferably physically
CC linked to GSC and GOI expression cassettes, where the endogenous
CC essential genes of cell substrate refer to genes or combination of genes
CC that are essential for cell survival and / or cell proliferation. The GIC
CC comprises a vector comprising a promoter operably linked to RNA
CC interference, RNAi (shRNA) / dsRNA / ribozyme molecule, or tandem repeats
CC of such transcript units, targeted to cell endogenous essential mRNA. The
CC invention provides strategies for increasing the productivity of
CC recombinant protein expression in isogenic cell-lines, and a novel
CC selection system for the improved stability and homogeneity of transgene
CC expression in isogenic cells without dependence on continuous selective
CC drugs. An example of the invention provides an essential gene knock-down
CC cassette, targeted at 3' UTR of human endogenous Yes1 gene, and a
CC supplementary Yes1 expression cassette which uses a 3' UTR from bovine
CC growth hormone (BGH) polyA. The present sequence is a bovine growth
CC hormone (BGH) polyA Yes1 supplementary expression cassette 3' UTR, used
CC in an example of the invention. Note: This version of SEQ ID 30 is given
CC in example 3, but it is not the same as the sequence referred to as SEQ
CC ID 30 (seeAXQ61560) in the sequence listing.

A poly-A sequence comprising SEQ ID NO 20 is component (viii) of the instant claims.
It would have been obvious to an artisan before the effective filing date of the claimed invention to modify the invention of the US191 claims with the sequence encoding CLRN1 of WO900 and the teachings about a polyA sequence of Powell and App178 for the benefits of using the US191 vectors to treat Usher syndrome and to increase transgene expression. One would have been motivated to do so with a reasonable expectation of success because Powell teaches that a bovine growth hormone polyA signal can increase transgene expression. One would have been motivated to do so with a reasonable expectation of success because WO900 teaches (¶3-4) expressing CLRN1 had known usage in treating Usher syndrome, including (¶11) for both hearing and vision losses, and it would have been a simple matter to swap the sequence encoding CLRN1 of WO900 for the sequence encoding otoferlin of US191. An artisan would know that they need only use one AAV vector to encode CLRN1 because WO900 teaches (¶99, 108-111) the entire mCLRN1 cDNA was placed on a single AAV vector, indicating the entire CLRN1 cDNA could fit on a single AAV vector. They would have been motivated to use a single vector because it is simpler to administer a single vector gene therapy than a dual vector gene therapy.
US952 teaches (Col 11 L3-15) a kit that comprises nucleic acid compounds within a container of solution and that the kit can comprise a pre-loaded syringe comprising the compounds. An artisan would have put their compounds into a kit comprising a pre-loaded syringe for the benefit of ensuring that the recipient has the exact dosage ready to administer and because doing so would have prevented any complications that arise from mixing a solution and then getting the mixed solution into a syringe.
Therefore the instant claims would have been obvious in view of the US191 claims, WO900, Powell, App178, and US952.
Claims 229-232, 247-254, and 256-270 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 39, 44, 55, 58-63, 65, 69, 71, 74, 77, 87-101 of copending Application No. 17628266 (reference application; “App266”) in view of Powell, WO900, App178, and US952. This rejection is maintained and updated in response to the claim amendments. All supporting references are of record.
Although the claims at issue are not identical, they are not patentably distinct from each other because both claim sets are directed to methods and compositions of gene therapies for expressing a gene of interest in the inner ear to treat hearing loss. The instant claims recite a composition comprising an AAV nucleic acid vector wherein the vector comprises a 5’ ITR, a CMV enhancer, a CBA promoter, a chimeric intron, a 5’UTR, a coding sequence (CDS) encoding a CLRN1 protein according to SEQ ID NO 3, a 3’UTR, a polyA signal, and a 3’ITR, wherein the CDS comprises a nt sequence spanning 2 consecutive exons of CLRN1 genomic DNA and lacks an intron sequence between them; wherein the composition can comprise other components such as SEQ ID NOs 16-17 or 20; to the composition comprising an excipient; to an AAV2 capsid comprising the composition, to an Anc80 capsid comprising the composition; to a kit comprising the composition; and to methods of introducing it to a cochlea of a mammal that can be a human who can have been previously identified as having a defective endogenous CLRN1 gene; to methods of increasing CLRN1 expression in the ear or eye; and to methods of treating hearing or vision loss.
The App266 claims are very broad and recite a construct comprising a promoter that can be a chicken β-actin promoter, a chimeric intron comprising SEQ ID NO 19 (i.e., claimed SEQ ID NO 16), a CVM enhancer comprising SEQ ID NO 17, a 5’UTR and a 3’UTR, two AAV ITRs flanking the coding sequence, and methods of using the construct to treat hearing loss. App266 claim 1 recites that the coding sequence can encode any secreted protein. App266 claims recite an AAV2 capsid or Anc80 capsid comprising the construct.
Both claim sets are directed to constructs for gene expression in the ear, wherein the constructs comprise the same elements including a chimeric intron comprising SEQ ID NO 16 and a CVM enhancer comprising SEQ ID NO 17. App266 SEQ ID NO 17 is identical to claimed SEQ ID NO 17:

Therefore the App266 claims recite elements (i), (ii), (iii), (iv), (v), (vii) and (ix) of the claimed invention. Then the other prior art teaches the other claim elements that the App266 claims do not recite:
The App266 claims recite the construct encodes a different protein than CLRN1, but WO900 (¶99) teaches an rAAV vector comprising the CLRN1 cDNA. WO900 teaches (¶9-10) the polynucleotide (polynt) can include a sequence having SEQ ID NO 2 (which it specifies comprises a 5’UTR and 3’UTR) and can be included on a vector that can be an adeno-associated viral vector (AAV) that can be used for transfecting ocular cells or cells of the inner ear.
WO900 SEQ ID NO 2 comprises a polynt comprising a sequence encoding the amino acid sequence of instant SEQ ID NO 3 (which has been back-translated from AA[Wingdings font/0xE0]nucleotides). This is shown by the following sequence alignment:

CC The present invention relates to a method for generating cell clones with
CC stable transgene (Gene Of Interest (GOI)) expression. The method of the
CC invention comprises: (i) inactivation of endogenous essential genes of
CC cell substrate through Gene Inactivation Cassettes (GIC), (ii) trans-
CC complementation of essential gene products through Gene Supplementary
CC Cassettes (GSC), alternatively, the cassette codes for the gene product
CC that is capable of inactivating GIC function, (iii) the GOI expression
CC cassettes are preferably, physically linked to GSC to take advantage of
CC favourable selective pressure, (iv) GIC could be preferably physically
CC linked to GSC and GOI expression cassettes, where the endogenous
CC essential genes of cell substrate refer to genes or combination of genes
CC that are essential for cell survival and / or cell proliferation. The GIC
CC comprises a vector comprising a promoter operably linked to RNA
CC interference, RNAi (shRNA) / dsRNA / ribozyme molecule, or tandem repeats
CC of such transcript units, targeted to cell endogenous essential mRNA. The
CC invention provides strategies for increasing the productivity of
CC recombinant protein expression in isogenic cell-lines, and a novel
CC selection system for the improved stability and homogeneity of transgene
CC expression in isogenic cells without dependence on continuous selective
CC drugs. An example of the invention provides an essential gene knock-down
CC cassette, targeted at 3' UTR of human endogenous Yes1 gene, and a
CC supplementary Yes1 expression cassette which uses a 3' UTR from bovine
CC growth hormone (BGH) polyA. The present sequence is a bovine growth
CC hormone (BGH) polyA Yes1 supplementary expression cassette 3' UTR, used
CC in an example of the invention. Note: This version of SEQ ID 30 is given
CC in example 3, but it is not the same as the sequence referred to as SEQ
CC ID 30 (seeAXQ61560) in the sequence listing.

The App266 claims do not recite a kit that comprises a pre-loaded syringe. However, US952 teaches (Col 11 L3-15) a kit that comprises nucleic acid compounds within a container of solution and that the kit can comprise a pre-loaded syringe comprising the compounds. An artisan would have put their compounds into a kit comprising a pre-loaded syringe for the benefit of ensuring that the recipient has the exact dosage ready to administer and because doing so would have prevented any complications that arise from mixing a solution and then getting the mixed solution into a syringe.
Therefore it would have been obvious to use WO900’s SEQ ID NO 2 with the expression construct of App266 in order to express CLRN1. An artisan would have known that using WO900’s sequence and teachings with the invention recited in the App266 claims and modified by the teachings of Powell, App178, and US952 would have provided a benefit of treating hearing or vision loss because WO900 teaches that (¶11). Using the bovine growth hormone polyA signal of App178 would have been of benefit based on the teachings of Powell. Packaging it into a pre-loaded syringe would also have been of benefit as taught by US952. There is no reason why the invention of the App266 claims are exclusively for expression of secreted proteins. Using WO900’s sequence and teachings with the invention recited in the App266 claims and modified by the teachings of Powell, App178, and US952 would have produced the instant invention.
This is a provisional nonstatutory double patenting rejection.
Claims 229-232, 247-254, and 256-270 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 63, and 66-68 of Application No. 18134095 (reference application; “App095”) in view of WO900 and US952. The App095 claims have now issued as US Pat. No. 12365726. This rejection is maintained and updated in response to the claim amendments. All supporting references are of record.
Although the claims at issue are not identical, they are not patentably distinct from each other because both claim sets are directed to methods and compositions of gene therapies for expressing a gene of interest in the inner ear to treat hearing loss. The instant claims recite a composition comprising an AAV nucleic acid vector wherein the vector comprises a 5’ ITR, a CMV enhancer, a CBA promoter, a chimeric intron, a 5’UTR, a coding sequence (CDS) encoding a CLRN1 protein according to SEQ ID NO 3, a 3’UTR, a polyA signal, and a 3’ITR, wherein the CDS comprises a nt sequence spanning 2 consecutive exons of CLRN1 genomic DNA and lacks an intron sequence between them; wherein the composition can comprise other components such as SEQ ID NOs 16-17 or 20; to the composition comprising an excipient; to an AAV2 capsid comprising the composition, to an Anc80 capsid comprising the composition; to a kit comprising the composition; and to methods of introducing it to a cochlea of a mammal that can be a human who can have been previously identified as having a defective endogenous CLRN1 gene; to methods of increasing CLRN1 expression in the ear or eye; and to methods of treating hearing or vision loss.
The App095 claims recite an AAV particle comprising a nucleic acid construct according to SEQ ID NO 91 or 92 and an AAV capsid, wherein the capsid can be an AAV2 capsid or an Anc80 capsid; and a kit and composition comprising the particle. An artisan would not know what are SEQ ID NO 91 or 92 but they would consult the Spec. (¶29, ) and SEQ listing and find that those SEQ ID NOs comprise a 5’ITR, a CMV enhancer comprising claimed SEQ ID NO 17, a CBA promoter, a chimeric intron according claimed SEQ ID NO 16, a coding sequence, and a 3’ITR.
Both claim sets are directed to AAV constructs for gene expression, wherein the constructs comprise the same elements including a chimeric intron comprising SEQ ID NO 16 and a CVM enhancer comprising SEQ ID NO 17 and a polyA sequence comprising SEQ ID NO 20. App095 SEQ ID NOs 91 and 92 comprise regions identical to claimed SEQ ID NOs 17, 16, and 20:

Therefore the App095 claims recite elements (i), (ii), (iii), (iv), (viii), and (ix) of the claimed invention. Then the other prior art teaches the other claim elements that the App095 claims do not recite:
WO900 teaches (¶99) an rAAV vector comprising the CLRN1 cDNA including the 5’ and 3’UTRs, and teaches driving it with the chicken β-actin promoter. WO900 teaches (¶9-10) the polynucleotide (polynt) can include a sequence having SEQ ID NO 2 (which it specifies comprises a 5’UTR and 3’UTR) and can be included on a vector that can be an adeno-associated viral vector (AAV) that can be used for transfecting ocular cells or cells of the inner ear. WO900 teaches (¶21) that the heterologous polynucleotide comprised in the AAV vector is flanked by at least one, and generally by two AAV inverted terminal repeat sequence (ITRs); an artisan would realize that being flanked by two ITRs refers to one ITR on either side, which is a 5’ITR and a 3’ITR.
WO900 SEQ ID NO 2 comprises a polynt comprising a sequence encoding the amino acid sequence of instant SEQ ID NO 3 (which has been back-translated from AA[Wingdings font/0xE0]nucleotides). This is shown by the following sequence alignment:

That alignment shows that the composition of WO900 comprises SEQ ID NO 3 itself, a 5’UTR, and a 3’UTR. Those are elements (v), (vi), and (vii) of the instant claims. WO900 teaches (¶10-11) treating retinal cells.
The App095 claims do not recite a kit that comprises a pre-loaded syringe. However, US952 teaches (Col 11 L3-15) a kit that comprises nucleic acid compounds within a container of solution and that the kit can comprise a pre-loaded syringe comprising the compounds. An artisan would have put their compounds into a kit comprising a pre-loaded syringe for the benefit of ensuring that the recipient has the exact dosage ready to administer and because doing so would have prevented any complications that arise from mixing a solution and then getting the mixed solution into a syringe.
Therefore it would have been obvious to use WO900’s SEQ ID NO 2 with the AAV particle of App095 in order to express CLRN1. An artisan would have known that using WO900’s sequence and teachings with the invention recited in the App095 claims and modified by the teachings of Powell, App178, and US952 would have provided a benefit of treating hearing or vision loss because WO900 teaches that (¶11), and it would have been a simple matter to swap the sequence encoding CLRN1 of WO900 for the sequence encoding a VEGF antibody of the App095 claims. Packaging it into a pre-loaded syringe would also have been of benefit as taught by US952. Using WO900’s sequence and teachings with the invention recited in the App095 claims and modified by the teachings of US952 would have produced the instant invention.
Therefore the instant claims would have been obvious in view of the App095 claims, WO900, and US952.
Claims 229-232, 247-254, and 256-270 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 103-127 of copending Application No. 18696131 (reference application; “App131”) in view of Powell, WO900, Landegger (et al. 2017. A synthetic AAV vector enables safe and efficient gene transfer to the mammalian inner ear. Nat. Biotechnol. 35[3]:280-286, “Landegger”, of record on IDS), App178, and US952. This rejection is maintained and updated in response to the claim amendments. All supporting references are of record.
Although the claims at issue are not identical, they are not patentably distinct from each other because both claim sets are directed to methods and compositions of gene therapies for expressing a gene of interest in the inner ear to treat hearing loss. The instant claims recite a composition comprising an AAV nucleic acid vector wherein the vector comprises a 5’ ITR, a CMV enhancer, a CBA promoter, a chimeric intron, a 5’UTR, a coding sequence (CDS) encoding a CLRN1 protein according to SEQ ID NO 3, a 3’UTR, a polyA signal, and a 3’ITR, wherein the CDS comprises a nt sequence spanning 2 consecutive exons of CLRN1 genomic DNA and lacks an intron sequence between them; wherein the composition can comprise other components such as SEQ ID NOs 16-17 or 20; to the composition comprising an excipient; to an AAV2 capsid comprising the composition, to an Anc80 capsid comprising the composition; to a kit comprising the composition; and to methods of introducing it to a cochlea of a mammal that can be a human who can have been previously identified as having a defective endogenous CLRN1 gene; to methods of increasing CLRN1 expression in the ear or eye; and to methods of treating hearing or vision loss.
The App131 claims recite a composition comprising a construct, wherein the construct comprises SEQ ID NO 333, an AAV particle comprising the construct, and methods of administering the AAV to a cochlea. An artisan would not know what is SEQ ID NO 333 but they would consult the SEQ listing and find that it comprises a 5’ITR, a CMV enhancer comprising claimed SEQ ID NO 17, a CBA promoter, a chimeric intron according claimed SEQ ID NO 16, a coding sequence, and a 3’ITR.
Both claim sets are directed to constructs for gene expression in the cochlea, wherein the constructs comprise the same elements including a chimeric intron comprising SEQ ID NO 19 and a CVM enhancer comprising SEQ ID NO 17. App131 SEQ ID NO 333 comprises regions identical to claimed SEQ ID NOs 17 and 16:

CC The present invention relates to a method for generating cell clones with
CC stable transgene (Gene Of Interest (GOI)) expression. The method of the
CC invention comprises: (i) inactivation of endogenous essential genes of
CC cell substrate through Gene Inactivation Cassettes (GIC), (ii) trans-
CC complementation of essential gene products through Gene Supplementary
CC Cassettes (GSC), alternatively, the cassette codes for the gene product
CC that is capable of inactivating GIC function, (iii) the GOI expression
CC cassettes are preferably, physically linked to GSC to take advantage of
CC favourable selective pressure, (iv) GIC could be preferably physically
CC linked to GSC and GOI expression cassettes, where the endogenous
CC essential genes of cell substrate refer to genes or combination of genes
CC that are essential for cell survival and / or cell proliferation. The GIC
CC comprises a vector comprising a promoter operably linked to RNA
CC interference, RNAi (shRNA) / dsRNA / ribozyme molecule, or tandem repeats
CC of such transcript units, targeted to cell endogenous essential mRNA. The
CC invention provides strategies for increasing the productivity of
CC recombinant protein expression in isogenic cell-lines, and a novel
CC selection system for the improved stability and homogeneity of transgene
CC expression in isogenic cells without dependence on continuous selective
CC drugs. An example of the invention provides an essential gene knock-down
CC cassette, targeted at 3' UTR of human endogenous Yes1 gene, and a
CC supplementary Yes1 expression cassette which uses a 3' UTR from bovine
CC growth hormone (BGH) polyA. The present sequence is a bovine growth
CC hormone (BGH) polyA Yes1 supplementary expression cassette 3' UTR, used
CC in an example of the invention. Note: This version of SEQ ID 30 is given
CC in example 3, but it is not the same as the sequence referred to as SEQ
CC ID 30 (seeAXQ61560) in the sequence listing.

A poly-A sequence comprising SEQ ID NO 20 is component (viii) of the instant claims.
The App131 claims do not recite a kit that comprises a pre-loaded syringe. However, US952 teaches (Col 11 L3-15) a kit that comprises nucleic acid compounds within a container of solution and that the kit can comprise a pre-loaded syringe comprising the compounds. An artisan would have put their compounds into a kit comprising a pre-loaded syringe for the benefit of ensuring that the recipient has the exact dosage ready to administer and because doing so would have prevented any complications that arise from mixing a solution and then getting the mixed solution into a syringe.
Therefore it would have been obvious to use WO900’s SEQ ID NO 2 with the expression construct of App131 in order to express CLRN1. An artisan would have known that using WO900’s sequence and teachings with the invention recited in the App131 claims and modified by the teachings of Powell, App178, and US952 would have provided a benefit of treating hearing or vision loss because WO900 teaches that (¶11), and it would have been a simple matter to swap the sequence encoding CLRN1 of WO900 for the sequence encoding a Kv7.4 protein of the App131 claims. Using the bovine growth hormone polyA signal of App178 would have been of benefit based on the teachings of Powell. It would have been obvious to use Landegger’s Anc80 vector because it is well tolerated. Packaging it into a pre-loaded syringe would also have been of benefit as taught by US952. Using WO900’s sequence and teachings with the invention recited in the App131 claims and modified by the teachings of Landegger, Powell, App178, and US952 would have produced the instant invention.
Therefore the instant claims would have been obvious in view of the App131 claims, WO900, Landegger, Powell, App178, and US952.
This is a provisional nonstatutory double patenting rejection.
Claims 229-232, 247-254, and 256-270 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 10-11, 13-17, 19-24, and 38-50 of copending Application No. 18269307 (reference application; “App307”; of record) in view of US Patent No. 8980952, issued 17 March 2015 (“US952”) and WO900. This rejection is maintained and updated in response to the claim amendments. All references are of record.
Although the claims at issue are not identical, they are not patentably distinct from each other because the instant claims recite a composition comprising an AAV nucleic acid vector wherein the vector comprises a 5’ ITR, a CMV enhancer, a CBA promoter, a chimeric intron according to SEQ ID NO 16, a 5’UTR, a coding sequence (CDS) encoding a CLRN1 protein according to SEQ ID NO 3, a 3’UTR, a polyA signal, and a 3’ITR, wherein the CDS comprises a nt sequence spanning 2 consecutive exons of CLRN1 genomic DNA and lacks an intron sequence between them; wherein the composition can comprise other components such as SEQ ID NOs 17 or 20; to the composition comprising an excipient; to an AAV2 capsid comprising the composition, to an Anc80 capsid comprising the composition; to a kit comprising the composition; and to methods of introducing it to a cochlea of a mammal that can be a human who can have been previously identified as having a defective endogenous CLRN1 gene; to methods of increasing CLRN1 expression in the ear or eye; and to methods of treating hearing or vision loss.
The App307 claims are drawn to a gene therapy comprising an AAV particle comprising a 5’ ITR, a CMV enhancer, a CBA promoter, a chimeric intron, a 5’UTR, a coding sequence (CDS) encoding a CLRN1 protein according to SEQ ID NO 1, a 3’UTR, a polyA signal, and a 3’ITR, wherein the CLRN1 protein can have SEQ ID NO 10, can have a polyA signal, CMV enhancer, or chimeric intron according to SEQ ID NOs 44, 38, or 39; wherein the particle can comprise an AAV capsid and the capsid can be an Anc80 capsid, and to methods of treating vision or hearing loss. Both claim sets are drawn to gene therapies for treating hearing and vision loss by administering a gene therapy encoding a CLRN1 protein.
Instant SEQ ID NO 3 is the same as App307 SEQ ID NO 10 (recited in App307 Claim 45), as shown by the following alignment:

The App307 claims do not recite that the kit (App307 Claim 14) comprises a pre-loaded syringe. However, US952 teaches (Col 11 L3-15) a kit that comprises nucleic acid compounds within a container of solution and that the kit can comprise a pre-loaded syringe comprising the compounds. An artisan would have put their compounds into a kit comprising a pre-loaded syringe for the benefit of ensuring that the recipient has the exact dosage ready to administer and because doing so would have prevented any complications that arise from mixing a solution and then getting the mixed solution into a syringe.
The App307 claims don’t recite AAV2 or delivering to a retinal cell but WO900 teaches (¶10-11) treating retinal cells and (¶72) AAV2.
Therefore the instant claims would have been obvious in view of App307 claims and US952 and WO900, and the methods of the instant claims could not be used without the composition and methods of App307 claims and US952. The App307 claims encompass the invention of the instant claims.
This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
Claims 259-260 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 8-10, 12-13, 17, 87, 91-92, 106, 109, 113-114, 117-118, 120, 129, 131, 133, 142, 157, and 167 of copending Application No. 18314671 (reference application; “App671”; of record) and in view of International Publication Number WO900 (of record), NCBI (of record), Landegger (et al. 2017. A synthetic AAV vector enables safe and efficient gene transfer to the mammalian inner ear. Nat. Biotechnol. 35[3]:280-286, “Landegger”, of record on IDS), and Powell. This rejection is maintained and updated in response to the claim amendments. All references are of record.
Although the claims at issue are not identical, they are not patentably distinct from each other because both claim sets are directed to methods and compositions of gene therapies for expressing a gene of interest in the inner ear to treat hearing loss. The instant claims recite a composition comprising an AAV nucleic acid vector wherein the vector comprises a 5’ ITR, a CMV enhancer, a CBA promoter, a chimeric intron, a 5’UTR, a coding sequence (CDS) encoding a CLRN1 protein according to SEQ ID NO 3, a 3’UTR, a polyA signal, and a 3’ITR; to an AAV2 capsid comprising the composition, to an Anc80 capsid comprising the composition; wherein the CDS comprises a nt sequence spanning 2 consecutive exons of CLRN1 genomic DNA and lacks an intron sequence between them.
The App671 claims broadly recite an expression construct comprising a polynucleotide encoding a polypeptide linked to a promoter and methods of using the construct to treat hearing loss, an AAV particle comprising the vector. The App671 claims in combination with the prior art encompass the instant claims because the App671 claims require only an expression construct comprising a polynucleotide encoding a polypeptide operably linked to a specific promoter and the instant claims recite a vector comprising a CDS of a CLRN1 protein. The operably linked polynucleotide sequence of the App671 claims could be any operably linked polynucleotide sequence. Using the invention of the App671 claims to express the CLRN1 gene is an expressly disclosed embodiment of App671 (see ¶139). The AAV vector recited in the instant claims is a kind of expression construct. Other App671 claims recite methods of expressing the polypeptide or increasing expression of the polypeptide in the ear, which also encompasses the instant claims. Furthermore, the App671 claims specify promoters that include a vimentin promoter and insulin promoter; both of these kinds of promoter are expressly disclosed embodiments of the instant invention (pp. 118-121 L1-7) and NCBI teaches the sequence of at least App671 SEQ ID NO 57.
App671 does not teach instant SEQ ID NO 3 but WO900 teaches SEQ ID NO 2 which encodes the product of instant SEQ ID NO 3. WO900 teaches (¶99) an rAAV vector comprising the CLRN1 cDNA including the 5’ and 3’UTRs, and teaches driving it with the chicken β-actin promoter. WO900 teaches (¶10-11) treating retinal cells.
Therefore it would have been obvious to use WO900’s SEQ ID NO 2 with the expression construct of App671 in order to express CLRN1 which, as stated, is an expressly disclosed embodiment of App671. Doing so would have produced the instant invention. Using WO900’s sequence and teachings with the invention recited in the App671 claims would have provided a benefit of treating hearing or vision loss.
The App671 claims do not recite a CMV enhancer, a chimeric intron, or that the polyA signal is a bovine growth hormone polyA signal.
Landegger teaches (§Abstract) an Anc80 vector for transgene delivery to the cochlea. Landegger teaches the vector is well tolerated and targets outer hair cells at high rates.
Powell teaches (§Polyadenylation Signal Sequences and Upstream Enhancer) one study, in human epithelial-like cells, found that a transgene had a 2.5-fold increase in expression with … bovine growth hormone polyA (bGHpA) signal sequences compared to a minimal synthetic polyA (SPA) signal. Powell teaches (§CMV Enhancer) the CMV enhancer increases transgene expression under different cell-specific promoters and different cell types making it a broadly applicable tool to increase transgene expression levels. Powell teaches (§Introns) the presence of an intron or intervening sequence in mRNA was first described, in vitro, to be important for mRNA processing and increased transgene expression… and … a hybrid intron (adenovirus/mouse immunoglobulin) increased transgene expression by 1.6-fold. Powell’s Table 3 shows that chimeric introns could improve expression, depending on the intron. A hybrid intron is simply another term for a chimeric intron. Altogether, Powell teaches that each of those elements—a CMV enhancer, a chimeric intron, and a bovine growth hormone polyA signal—can increase transgene expression. It would have been obvious to a person of ordinary skill in the art before the effective filing date of the instant invention to modify the compositions and methods of the App671 claims and WO900 with the CMV enhancer, chimeric intron, and bovine growth hormone polyA signal of Powell for the benefit of improving transgene expression. One would have been motivated to do so with a reasonable expectation of success because Powell teaches that each element improves transgene expression in gene therapy. It would have been obvious to use Landegger’s Anc80 vector because it is well tolerated.
Therefore, the instant claims would have been obvious in view of the App671 claims and the prior art of WO900, Landegger, and Powell.
This is a provisional nonstatutory double patenting rejection.
Claims 259-260 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 4, 10-12, 14, 21, 24, 26, 31-32, 34, 36, 38-39, 42-46, 48, 51, 54-55, 57, 70, and 78 of copending Application No. 18697425 (reference application; “App425”) in view of WO900 and Powell. This rejection is maintained and updated in response to the claim amendments. All references are of record.
Although the claims at issue are not identical, they are not patentably distinct from each other because both claim sets are directed to methods and compositions of gene therapies for expressing a CLRN1 in the cochlea to treat hearing loss. The instant claims recite a composition comprising an AAV nucleic acid vector wherein the vector comprises a 5’ ITR, a CMV enhancer, a CBA promoter, a chimeric intron, a 5’UTR, a coding sequence (CDS) encoding a CLRN1 protein according to SEQ ID NO 3, a 3’UTR, a polyA signal, and a 3’ITR; to an AAV2 capsid comprising the composition, to an Anc80 capsid comprising the composition; wherein the CDS comprises a nt sequence spanning 2 consecutive exons of CLRN1 genomic DNA and lacks an intron sequence between them. The App425 claims are broadly directed to a construct comprising a polynucleotide encoding a polypeptide linked to a promoter which expresses the polynucleotide in an outer hair cell, wherein the promoter can be an OCM or prestin promoter and wherein the polynucleotide can encode CLRN1, the vector can be AAV, and to methods of using the construct to treat hearing loss.
The broad App425 claims read on the instant claims because the App425 claims require only an expression construct comprising a polynucleotide encoding a polypeptide operably linked to a specific promoter, wherein the gene can be CLRN1 (see Claim 12), and the instant claims recite an AAV vector comprising a CDS of a CLRN1 protein, and an AAV particle that can comprise an AAV capsid wherein the capsid can be an AAV2 capsid or an Anc80 capsid. An OCM or prestin promoter are (p. 121 L1-5) explicitly disclosed embodiments of the instant Spec. The operably linked polynucleotide sequence of the App425 claims could be any operably linked polynucleotide sequence and App425 Claim 12 explicitly recites CLRN1. The outer hair cell of the App425 claims is located within the cochlea.
App425 does not teach a chicken β-actin promoter or claimed SEQ ID NO 3 but WO900 teaches SEQ ID NO 2 which encodes the product of instant SEQ ID NO 3 and (¶99) the CLRN1 cDNA comprises the 5’ and 3’UTRs, and teaches driving it with the chicken β-actin promoter. WO900 teaches (¶10-11) treating retinal cells.
Powell teaches (§Polyadenylation Signal Sequences and Upstream Enhancer) one study, in human epithelial-like cells, found that a transgene had a 2.5-fold increase in expression with … bovine growth hormone polyA (bGHpA) signal sequences compared to a minimal synthetic polyA (SPA) signal. Powell teaches (§CMV Enhancer) the CMV enhancer increases transgene expression under different cell-specific promoters and different cell types making it a broadly applicable tool to increase transgene expression levels. Powell teaches (§Introns) the presence of an intron or intervening sequence in mRNA was first described, in vitro, to be important for mRNA processing and increased transgene expression… and … a hybrid intron (adenovirus/mouse immunoglobulin) increased transgene expression by 1.6-fold. Powell’s Table 3 shows that chimeric introns could improve expression, depending on the intron. A hybrid intron is simply another term for a chimeric intron. Altogether, Powell teaches that each of those elements—a CMV enhancer, a chimeric intron, and a bovine growth hormone polyA signal—can increase transgene expression.
It would have been obvious to a person of ordinary skill in the art before the effective filing date of the instant invention to modify the compositions and methods of the App425 claims with the CBA-driven CLRN1 of WO900 and with the CMV enhancer, chimeric intron, and bovine growth hormone polyA signal of Powell for the benefits of improving transgene expression. One would have been motivated to do so with a reasonable expectation of success because Powell teaches that each element improves transgene expression in gene therapy.
Therefore it would have been obvious to use the expression construct of the App425 claims and WO900’s SEQ ID NO 2 and additional components of Powell in order to express CLRN11. Doing so would have produced the instant invention. Using WO900’s sequence and teachings with the invention recited in the App425 claims would have provided a benefit of treating hearing or vision loss. The instant claims would have been obvious in view of the App425 claims, WO900, and Powell.
This is a provisional nonstatutory double patenting rejection.
Claims 229-232, 247-254, and 259-270 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-28, 32-34, 37, 41-42, 44-46, 48-51, 53-124, 127, 131-132, 134-136, 138-141, 143-199 of copending Application No. 18866969 (reference application; “App969”) in view of WO900, Powell, App178, and US952. This rejection is maintained and updated in response to the claim amendments. All supporting references are of record.
Although the claims at issue are not identical, they are directed to overlapping subject matter because the instant claims recite a composition comprising an AAV nucleic acid vector wherein the vector comprises a 5’ ITR, a CMV enhancer, a CBA promoter, a chimeric intron according to SEQ ID NO 16, a 5’UTR, a coding sequence (CDS) encoding a CLRN1 protein according to SEQ ID NO 3, a 3’UTR, a polyA signal, and a 3’ITR, wherein the CDS comprises a nt sequence spanning 2 consecutive exons of CLRN1 genomic DNA and lacks an intron sequence between them; wherein the composition can comprise other components such as SEQ ID NOs 17 or 20; to the composition comprising an excipient; to an AAV2 capsid comprising the composition, to an Anc80 capsid comprising the composition; to a kit comprising the composition; and to methods of introducing it to a cochlea of a mammal that can be a human who can have been previously identified as having a defective endogenous CLRN1 gene; to methods of increasing CLRN1 expression in the ear or eye; and to methods of treating hearing or vision loss.
The copending App969 claims are drawn to a plurality of recombinant AAV vectors: a first vector comprising first expression cassette comprising a promoter operably linked to a nucleic acid sequence comprising an otoferlin gene, wherein the cassette is flanked by ITRs, and wherein the expression cassette can have a sequence with at least 70% identity to SEQ ID NO 96; wherein the promoter can be a CBA promoter or a CMV promoter, and to a second vector that can comprise a polyA sequence including a bovine polyA sequence; wherein each of the vectors is encapsulated by an AAV capsid having a certain serotype, wherein the capsid can be an AAV2 capsid or an Anc80 capsid, to a composition comprising the vectors, wherein the composition can be formulated for intra-cochlear administration, to a method of expressing a recombinant full-length otoferlin protein in a mammalian cell, and/or to methods of treating hearing loss by administering the vectors into the cochlea of a subject; wherein the composition can be administered by a single injection to an inner ear cell, to a kit comprising a preloaded syringe comprising the composition,
Both claim sets are directed to AAV vectors for treating hearing loss in a mammal or human by administering the vector to the cochlea of the mammal/human.
An artisan would not know what is App969 SEQ ID NO 96 so they would consult the App969 Spec. and SEQ listing and find (pp. 104-113) SEQ ID NO 96 comprises two ITRs (a 5’ ITR and a 3’ITR), a CAG promoter comprising: a CMV enhancer, chicken β-actin gene sequence, and a chimeric intron comprising SEQ ID NO 100. App969 SEQ ID NO 96 comprises claimed SEQ ID NOs 16 and 17 as shown by the following alignments:

Therefore the copending App969 claims recite sequences that encompass claimed SEQ ID NOs 16 and 17. Therefore the copending App969 claims recite elements (i), (ii), (iii), (iv), and (ix) of the claimed invention. Then the other prior art teaches the other claim elements that the App969 claims do not recite:
WO900 teaches (¶99) an rAAV vector comprising the CLRN1 cDNA including the 5’ and 3’UTRs, and teaches driving it with the chicken β-actin promoter. WO900 teaches (¶9-10) the polynucleotide (polynt) can include a sequence having SEQ ID NO 2 (which it specifies comprises a 5’UTR and 3’UTR) and can be included on a vector that can be an adeno-associated viral vector (AAV) that can be used for transfecting ocular cells or cells of the inner ear. WO900 teaches (¶10-11) treating retinal cells.
WO900 SEQ ID NO 2 comprises a polynt comprising a sequence encoding the amino acid sequence of instant SEQ ID NO 3 (which has been back-translated from AA[Wingdings font/0xE0]nucleotides). This is shown by the following sequence alignment:

CC The present invention relates to a method for generating cell clones with
CC stable transgene (Gene Of Interest (GOI)) expression. The method of the
CC invention comprises: (i) inactivation of endogenous essential genes of
CC cell substrate through Gene Inactivation Cassettes (GIC), (ii) trans-
CC complementation of essential gene products through Gene Supplementary
CC Cassettes (GSC), alternatively, the cassette codes for the gene product
CC that is capable of inactivating GIC function, (iii) the GOI expression
CC cassettes are preferably, physically linked to GSC to take advantage of
CC favourable selective pressure, (iv) GIC could be preferably physically
CC linked to GSC and GOI expression cassettes, where the endogenous
CC essential genes of cell substrate refer to genes or combination of genes
CC that are essential for cell survival and / or cell proliferation. The GIC
CC comprises a vector comprising a promoter operably linked to RNA
CC interference, RNAi (shRNA) / dsRNA / ribozyme molecule, or tandem repeats
CC of such transcript units, targeted to cell endogenous essential mRNA. The
CC invention provides strategies for increasing the productivity of
CC recombinant protein expression in isogenic cell-lines, and a novel
CC selection system for the improved stability and homogeneity of transgene
CC expression in isogenic cells without dependence on continuous selective
CC drugs. An example of the invention provides an essential gene knock-down
CC cassette, targeted at 3' UTR of human endogenous Yes1 gene, and a
CC supplementary Yes1 expression cassette which uses a 3' UTR from bovine
CC growth hormone (BGH) polyA. The present sequence is a bovine growth
CC hormone (BGH) polyA Yes1 supplementary expression cassette 3' UTR, used
CC in an example of the invention. Note: This version of SEQ ID 30 is given
CC in example 3, but it is not the same as the sequence referred to as SEQ
CC ID 30 (seeAXQ61560) in the sequence listing.

A poly-A sequence comprising SEQ ID NO 20 is component (viii) of the instant claims.
It would have been obvious to an artisan before the effective filing date of the claimed invention to modify the invention of the App969 claims with the sequence encoding CLRN1 of WO900 and the teachings about a polyA sequence of Powell and App178 for the benefits of using the App969 vectors to treat Usher syndrome and to increase transgene expression. One would have been motivated to do so with a reasonable expectation of success because Powell teaches that a bovine growth hormone polyA signal can increase transgene expression. One would have been motivated to do so with a reasonable expectation of success because WO900 teaches (¶3-4) expressing CLRN1 had known usage in treating Usher syndrome, including (¶11) for both hearing and vision losses, and it would have been a simple matter to swap the sequence encoding CLRN1 of WO900 for the sequence encoding otoferlin of the App969 claims. An artisan would have known that they need only use one AAV vector to encode CLRN1 because WO900 teaches (¶99, 108-111) the entire mCLRN1 cDNA was placed on a single AAV vector, indicating the entire CLRN1 cDNA could fit on a single AAV vector. They would have been motivated to use a single vector because it is simpler to administer a single vector gene therapy than a dual vector gene therapy.
US952 teaches (Col 11 L3-15) a kit that comprises nucleic acid compounds within a container of solution and that the kit can comprise a pre-loaded syringe comprising the compounds. An artisan would have put their compounds into a kit comprising a pre-loaded syringe for the benefit of ensuring that the recipient has the exact dosage ready to administer and because doing so would have prevented any complications that arise from mixing a solution and then getting the mixed solution into a syringe.
Therefore the instant claims would have been obvious in view of the App969 claims, WO900, Powell, App178, and US952.
This is a provisional nonstatutory double patenting rejection.
Claims 229-232, 247-254, and 259-270 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 44, 49-56, 58-61, 66-77 of copending Application No. 19098662 (“App662”) in view of WO900, Powell, and US952. This rejection is maintained and updated in response to the claim amendments. All supporting references are of record.
Although the claims at issue are not identical, they are directed to overlapping subject matter because the instant claims recite a composition comprising an AAV nucleic acid vector wherein the vector comprises a 5’ ITR, a CMV enhancer, a CBA promoter, a chimeric intron according to SEQ ID NO 16, a 5’UTR, a coding sequence (CDS) encoding a CLRN1 protein according to SEQ ID NO 3, a 3’UTR, a polyA signal, and a 3’ITR, wherein the CDS comprises a nt sequence spanning 2 consecutive exons of CLRN1 genomic DNA and lacks an intron sequence between them; wherein the composition can comprise other components such as SEQ ID NOs 17 or 20; to the composition comprising an excipient; to an AAV2 capsid comprising the composition, to an Anc80 capsid comprising the composition; to a kit comprising the composition; and to methods of introducing it to a cochlea of a mammal that can be a human who can have been previously identified as having a defective endogenous CLRN1 gene; to methods of increasing CLRN1 expression in the ear or eye; and to methods of treating hearing or vision loss.
The App662 claims are drawn to a plurality of recombinant AAV vectors: a first vector comprising a 5’ITR, a 3’ITR, a CAG promoter comprising SEQ ID NO 61, and a second vector that can comprise a bovine polyA signal, wherein each of the vectors is encapsulated by an AAV capsid having a certain serotype, wherein the capsid can be an AAV2 or Anc80 capsid, to a composition comprising the vectors, wherein the composition can be formulated for intra-cochlear administration.
Both claim sets are directed to AAV vectors for administering a gene therapy to the cochlea.
An artisan would not know what is US191 SEQ ID NO 61 so they would consult the App662 Spec. and SEQ listing and find (p. 121; SEQ listing) SEQ ID NO 61 comprises a CAG promoter comprising: a CMV enhancer, chicken β-actin gene sequence, and a chimeric intron. App662 SEQ ID NO 61 comprises claimed SEQ ID NOs 16 and 17 as shown by the following alignments:

Therefore the copending App662 claims recite elements (i), (ii), (iii), (iv), (viii), and (ix) of the claimed invention. Then the other prior art teaches the other claim elements that the App662 claims do not recite:
WO900 teaches an rAAV vector comprising the CLRN1 cDNA including the 5’ and 3’UTRs. WO900 teaches (¶9-10) the polynucleotide (polynt) can include a sequence having SEQ ID NO 2 (which it specifies comprises a 5’UTR and 3’UTR) and can be included on a vector that can be an adeno-associated viral vector (AAV) that can be used for transfecting ocular cells or cells of the inner ear. WO900 teaches (¶21) that the heterologous polynucleotide comprised in the AAV vector is flanked by at least one, and generally by two AAV inverted terminal repeat sequence (ITRs); an artisan would realize that being flanked by two ITRs refers to one ITR on either side, which is a 5’ITR and a 3’ITR. WO900 teaches (¶10-11) treating retinal cells.
WO900 SEQ ID NO 2 comprises a polynt comprising a sequence encoding the amino acid sequence of instant SEQ ID NO 3 (which has been back-translated from AA[Wingdings font/0xE0]nucleotides). This is shown by the following sequence alignment:

That alignment shows that the composition of WO900 comprises SEQ ID NO 3 itself, a 5’UTR, and a 3’UTR. Those are elements (v), (vi), and (vii) of the instant claims.
Powell teaches (§Polyadenylation Signal Sequences and Upstream Enhancer) one study, in human epithelial-like cells, found that a transgene had a 2.5-fold increase in expression with … bovine growth hormone polyA (bGHpA) signal sequences compared to a minimal synthetic polyA (SPA) signal.
It would have been obvious to an artisan before the effective filing date of the claimed invention to modify the invention of the App662 claims with the sequence encoding CLRN1 of WO900 and teachings of Powell for the benefits of using the App662 vectors to treat Usher syndrome and to increase transgene expression. One would have been motivated to do so with a reasonable expectation of success because WO900 teaches (¶3-4) expressing CLRN1 had known usage in treating Usher syndrome, including (¶11) for both hearing and vision losses, and it would have been a simple matter to swap the sequence encoding CLRN1 of WO900 for the sequence encoding otoferlin of App662 .

They would have been motivated to use a single vector because it is simpler to administer a single vector gene therapy than a dual vector gene therapy. Using the bovine growth hormone polyA signal of App178 would have been of benefit based on the teachings of Powell.
US952 teaches (Col 11 L3-15) a kit that comprises nucleic acid compounds within a container of solution and that the kit can comprise a pre-loaded syringe comprising the compounds. An artisan would have put their compounds into a kit comprising a pre-loaded syringe for the benefit of ensuring that the recipient has the exact dosage ready to administer and because doing so would have prevented any complications that arise from mixing a solution and then getting the mixed solution into a syringe.
Therefore the instant claims would have been obvious in view of the App662 claims, WO900, Powell, and US952.
This is a provisional nonstatutory double patenting rejection.

However, WO937 provides no reason for an artisan to choose specifically bp 2408-3420 from SEQ ID NO 20, bp 2417-3429 from SEQ ID NO 18, bp 3233-4245 from SEQ ID NO 13, 3244-4256 from SEQ ID NO 10 and use them in the instant invention.
Response to Arguments
Applicant's arguments filed 10 October 2025 have been fully considered but they are not persuasive. Each rejection is addressed below. Arguments that are no longer relevant are not addressed.
NSDP rejections
Regarding the NSDP rejections, Applicant has disagreed with them because, they argue (pp. 10-14) the instantly claimed invention is filed earlier than any of the reference applications. That is not found persuasive because NSDP rejections over other applications and issued patents is necessary.
The claims of issued US Patents US867, US773, and US191 and copending applications App969 and App662 disclose vector sequences that comprise claimed SEQ ID NO 16 and all of the other claim elements would have been obvious in view of the cited prior art. Furthermore, it would have been obvious to an artisan to use a single vector to express CLRN1 because the prior art (i.e., WO900) discloses single AAV vectors for expressing CLRN1 and because it is simpler to administer a single vector gene therapy rather than a dual vector gene therapy. For example, WO900 teaches (¶85) vectors can be associated with immunogenic response and although AAV presents low risk for pathogenic reactions, (¶82) therapeutic effects must be balanced with toxic or detrimental effects from a vector. Since the art teaches that expressing CLRN1 requires only a single AAV vector, an artisan would have found it obvious and beneficial to do so.
The other prior art teaches the other elements of the claimed invention: WO900 teaches a nt sequence encoding 5’- and 3’-UTRs and claimed SEQ ID NO 3. WO900 teaches administration to retinal cells. Landegger teaches administering an Anc80 serotype. Powell teaches benefits of using a polyA signal and App178 teaches the polyA sequence that is claimed SEQ ID NO 20. US952 teaches a kit that comprises a pre-loaded syringe.
Regarding App095 (now issued as US Pat. No. 12365726), those claims are broadly directed to an AAV particle wherein the nucleic acid construct comprises SEQ ID NOs 91 or 92. As discussed in the NSDP rejection, those SEQ ID NOs comprise claimed SEQ ID NOs 16, 17, and 20. Like the other NSDP rejections, the other cited prior art teaches the remaining claim limitations that the reference application claims do not teach. It would have been obvious to swap the CLRN1 sequence of WO900 for the coding sequences within SEQ ID NOs 91 or 92.
Regarding the copending applications, MPEP §804(I)(B)(1)(b)(i) does not yet apply because those NSDP rejections are not the sole rejections remaining; there are NSDP rejections over issued patents.
Regarding App266, those claims are broadly directed to a construct for expressing a coding sequence of a secreted target protein. The App266 claims recite a chimeric intron sequence that is the same as claimed SEQ ID NO 16 and a CVM enhancer that is the same as claimed SEQ ID NO 17. There is no reason why an artisan could not use the construct of App266 claims to express any protein, including the CLRN1 protein of WO900.
Regarding App131, those claims are very broadly directed to a construct or AAV particle comprising SEQ ID NO 333 which, as discussed, comprises many of the instantly claimed elements, including SEQ ID NOs 16 and 17. Like the other NSDP rejections, the other cited prior art teaches the remaining claim limitations that the reference application claims do not teach and it would have been obvious to swap the CLRN1 sequence of WO900 for the coding sequences within SEQ ID NO 333.
Regarding App307, the NSDP rejection explains that those claims recite all the elements of the claimed invention besides for the kit and preloaded syringe.
Regarding App671 and App425, the NSDP rejections explain that those claims are broadly directed to AAV expression constructs for hearing loss would have made instant claims 259-260 obvious in view of the cited prior art.
In each case it would have been obvious to use the sequence encoding a CLRN1 protein of WO900 with the patented/copending inventions because WO900 teaches (¶3-4) expressing CLRN1 had known usage in treating Usher syndrome, including (¶11) for both hearing and vision losses, and it would have been a simple matter to swap the sequence encoding CLRN1 of WO900 for the sequences of the patented/copending claims.
Applicant argues (pp. 10-11) the rejections over the issued patents should be removed because double patenting is to avoid an unjustified extension or improper timewise extension of the right to exclude granted by a patent. Applicant argues that the granted patents have a later expiration date than the instant claims would have if they were granted.
Those arguments are not found persuasive. The following chart from MPEP 804 indicates than NSDP rejections should be made over the issued patents:

Greyscale
Note that withdrawal of an NSDP rejection when the application under examination has the earlier patent term filing date applies to provisional NSDP rejections, not rejections over issued patents:
If a provisional nonstatutory double patenting rejection is the only rejection remaining in an application having the earlier patent term filing date, the examiner should withdraw the rejection in the application having the earlier patent term filing date and permit that application to issue as a patent, thereby converting the provisional nonstatutory double patenting rejection in the other application into a nonstatutory double patenting rejection upon issuance of the patent. [emphasis added.] MPEP 804(I)(B)(1)(b)(i)
Furthermore, Applicant should note that the instant claims, if allowed, would improperly extend the "right to exclude" already granted in the issued patents. The subject matter claimed in the instant application would have been obvious in view of the issued patents and the prior art, as discussed in each NSDP rejection. Furthermore, there is no apparent reason why applicant was prevented from presenting claims corresponding to those of the instant application during prosecution of the applications which each matured into a patent. See In re Schneller, 397 F.2d 350, 158 USPQ 210 (CCPA 1968). See also MPEP § 804.
Information in the § about Terminal Disclaimers touches on the right to exclude (MPEP 804.02[IV]):
Each one of the commonly owned conflicting nonstatutory double patenting references must be included in the terminal disclaimer to avoid the problem of dual ownership of patents to patentably indistinct inventions in the event that the patent issuing from the application being examined ceases to be commonly owned with any one of the double patenting references that have issued or may issue as a patent. Note that 37 CFR 1.321(c)(3) requires that a terminal disclaimer for commonly owned conflicting claims "[i]nclude a provision that any patent granted on that application or any patent subject to the reexamination proceeding shall be enforceable only for and during such period that said patent is commonly owned with the application or patent which formed the basis for the judicially created double patenting."
Filing a terminal disclaimer including each one of the conflicting nonstatutory double patenting references is also necessary to avoid the problem of separate enforcement of patents to patentably indistinct inventions by parties to a joint research agreement.
MPEP 804.02(IV)
Note that the only way to overcome the NSDP rejections over the issued US patents is with persuasive arguments or a terminal disclaimer (TD).
Therefore all the NSDP rejections must be maintained until all the claims are ready to allow. The NSDP rejections over the issued patents must be maintained until they are either persuasively argued or a TD is filed.
Conclusion
Claims 229, 232, 257, and 259-270 are rejected.
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
