Claim Rejections - 35 USC § 112
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
2. Claims 27, 31, 35, and 39 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the enablement requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to enable one skilled in the art to which it pertains, or with which it is most nearly connected, to make and/or use the invention.
Claims 27, 31, 35, and 39 recite and encompass an antigen-binding molecule comprising:
“(a) a VH region comprising an amino acid sequence having at least 70% sequence identity to the amino acid sequence of SEQ ID NO:24, and comprising the following CDRs:
HC-CDR1 having the amino acid sequence of SEQ ID NO:41
HC-CDR2 having the amino acid sequence of SEQ ID NO:44
HC-CDR3 having the amino acid sequence of SEQ ID NO:47; and a VL region comprising an amino acid sequence having at least 70% sequence identity to the amino acid sequence of SEQ ID NO:74, and comprising the following CDRs:
LC-CDR1 having the amino acid sequence of SEQ ID NO:88
LC-CDR2 having the amino acid sequence of SAS (SEQ ID NO:92)
LC-CDR3 having the amino acid sequence of SEQ ID NO:95; or (b) …” and so forth.
A sequence alignment of the instantly claimed VH and VL SEQ ID NOs with the CDR SEQ ID NOs required to be present within them demonstrates a greater than 70% minimum sequence identity is required in order for the claimed VH and VL sequences to comprise the claimed CDR sequences. For example, VH SEQ ID NO:24 has an 84.1% sequence identity to a sequence comprising all of CDR SEQ ID NOs:41, 44, and 47 as recited by the claims (see sequence alignment below and Query Match %). Therefore, a sequence comprising less than 84.1% sequence identity to SEQ ID NO:24 (i.e., 70% as claimed) will exclude sequence identity to the CDR sequences required to be present, therefore, the claims as currently constituted are not enabled to comprise the claimed CDR sequences.
Similarly, VL SEQ ID NO:74 has a 71.9% sequence identity to a sequence comprising all of CDR SEQ ID NOs:88, SAS, and 95 as recited by the claims (see sequence alignment below and Query Match %). Therefore, a sequence comprising less than 71.9% sequence identity to SEQ ID NO:74 (i.e., 70% as claimed) will exclude sequence identity to the CDR sequences required to be present and is not enabled to comprise the claimed CDR sequences.
The same logic applies to the antigen-binding molecules recited in parts (b)-(q) of the claims.

Claim Rejections - 35 USC § 112
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
3. Claims 24, 28, 32, 36, and 40-43 remain rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for pre-AIA the inventor(s), at the time the application was filed, had possession of the claimed invention. This is a WRITTEN DESCRIPTION rejection.
The claims are drawn to:
an antigen-binding molecule comprising a heavy chain variable (VH) region and a light chain variable (VL) region, wherein the antigen-binding molecule specifically binds to HER3, and wherein binding to HER3 comprises contact with one or more amino acid residues of the region of HER3 shown in SEQ ID NO:230 and SEQ ID NO:231; a nucleic acid encoding the antibody, a cell comprising the nucleic acid encoding the antibody; and
a method of treating a cancer in a subject, comprising administering to a subject a therapeutically effective amount of an antigen-binding molecule comprising a heavy chain variable (VH) region and a light chain variable (VL) region, wherein the antigen-binding molecule specifically binds to HER3, and wherein binding to HER3 comprises contact with one or more amino acid residues of the region of HER3 shown in SEQ ID NO:230 and SEQ ID NO:231.
Thus, the claims identify the antigen-binding molecule by function only, where the function is to:
bind HER3 and come into contact with one or more amino acid residues of the region of HER3 shown in SEQ ID NO:230 and SEQ ID NO:231; and
treat cancer in a subject.
No antigen-binding molecule or antibody structure is recited.
The instant specification discloses seventeen total 10D1 antibody and 10D1-derived clones comprising defined pairs of VH and VL sequences in the Table of Example 1:
PNG
media_image1.png
668
430
media_image1.png
Greyscale
The instant specification discloses that the antibodies bind to a motif 1 (SEQ ID NO:230) and motif 2 (SEQ ID NO:231) within SEQ ID NO:229:
The site of HER3 to which 10D1 and 10D1-derived clones was determined to bind corresponds to positions 218 to 235 of the amino acid sequence of human HER3 (as shown e.g. In SEQ ID NO:1); the amino acid sequence for this region of HER3 Is shown in SEQ ID NO:229. Within this region, two consensus binding site motifs were identified, and are shown in SEQ ID NOs:230 and 231.
Thus, the instant specification describes seventeen 10D1 derivative antibodies that function as claimed, wherein each of the seventeen antibodies comprises a defined single set of VH and VL sequences. The specification fails to disclose any other antigen-binding molecules or antibodies that possess the function of binding HER3 and coming into contact with the region of HER3 shown in SEQ ID NO:230 and 231, and treating cancer in a subject.
To provide adequate written description and evidence of possession of the claimed antibody genus, the instant specification can structurally describe representative antigen-binding molecules or antibodies that function to bind HER3 and come into contact with SEQ ID NO:230 and 231, and treat cancer, or describe structural features common to the members of the genus, which features constitute a substantial portion of the genus. Alternatively, the specification can show that the claimed invention is complete by disclosure of sufficiently detailed, relevant identifying characteristics, functional characteristics when coupled with a known or disclosed correlation between function and structure, or some combination of such characteristics (see University of California v. Eli Lilly and Co., 119 F.3d 1559, 43 USPQ2d 1398 (Fed. Cir. 1997) and Enzo Biochem, Inc. V. Gen-Probe Inc.). A disclosure that does not adequately describe a product itself logically cannot adequately describe a method of using that product.
Although Applicants may argue that it is possible to screen for antibodies that bind HER3 and function as claimed, the court found in (Rochester v. Searle, 358 F.3d 916, Fed Cir., 2004) that screening assays are not sufficient to provide adequate written description for an invention because they are merely a wish or plan for obtaining the claimed chemical invention. “As we held in Lilly, “[a]n adequate written description of a DNA … ‘requires a precise definition, such as by structure, formula, chemical name, or physical properties,’ not a mere wish or plan for obtaining the claimed chemical invention.” 119 F.3d at 1566 (quoting Fiers, 984 F.2d at 1171). For reasons stated above, that requirement applies just as well to non-DNA (or RNA) chemical inventions.” Knowledge of screening methods provides no information about the structure of any future antibodies yet to be discovered that may function as claimed. The HER3 epitope comprising SEQ ID NO:230 and 231 provides no information about the structure of an antibody that binds to it.
In this case, the only factor present in the claims is a recitation of the antibody function. The instant specification fails to describe structural features common to the members of the genus, which features constitute a substantial portion of the genus because the instant specification discloses only seventeen defined exemplary antibody VH and VL sequence pairs that function as claimed. A definition by function does not suffice to define the genus because it is only an indication of what the antibody does, rather than what it is. Applicants have not established any reasonable structure-function correlation with regards to the sequences in the variable domains or CDRs that can be altered and still maintain the claimed functions of binding HER3 at epitopes SEQ ID NO:230 and 231 and treating cancer. The instant specification also fails to describe a representative number of antibody sequences for the genus of antibodies that function as claimed. One could not readily envision members of the broadly claimed genus required to practice the invention. Accordingly, in the absence of sufficient recitation of distinguishing identifying characteristics, the specification does not provide adequate written description of the claimed genus required to make and practice the claimed invention.
Given the lack of representative examples to support the full scope of the claimed antibodies and those used in the claimed method, and lack of reasonable structure-function correlation with regards to what sequences can be altered and maintain the claimed functions, the present claims lack adequate written description. Thus, the specification does not provide an adequate written description of antibodies that bind HER3 at epitopes SEQ ID NO:2301 and 231 that is required to practice the claimed invention. Since the specification fails to adequately describe the product to which the claimed method uses, it also fails to adequately describe the method.
Examiner Suggestion: Amend the rejected claims to recite and require the antigen-binding molecule/ antibody comprise at least the six heavy and light chain CDR SEQ ID NOs of claims 25 or 26 required to function as claimed.
Response to Arguments
4. Applicants argue that the disclosed seventeen 10D1 and 10D1 derivative antibodies are sufficiently representative of the claimed genus. Applicants argue that the claimed antibodies are readily obtainable by routine methods such as antibody phage display screening for HER3 antigen binding. Applicants argue that the decision in Rochester argued by Examiner is not applicable to the instant claims because in Rochester, no exemplary species of claimed non-steroidal compounds were disclosed in the specification. Applicants argue that in the instant case, they have disclosed seventeen exemplary species of antibody within their claimed genus.
5. The arguments have bene considered but are not persuasive. Contrary to arguments, the 17 disclosed species of highly homologous 10D1 and 10D1 derivative antibodies are not sufficiently representative of the claimed genus of antigen-binding molecules. When considering whether the specification discloses a sufficient representative number of species to satisfy written description, one must account for the breadth of the claimed genus.
MPEP 2163 states:
A "representative number of species" means that the species which are adequately described are representative of the entire genus. Thus, when there is substantial variation within the genus, one must describe a sufficient variety of species to reflect the variation within the genus. See AbbVie Deutschland GmbH & Co., KG v. Janssen Biotech, Inc., 759 F.3d 1285, 1300, 111 USPQ2d 1780, 1790 (Fed. Cir. 2014) (Claims directed to a functionally defined genus of antibodies were not supported by a disclosure that "only describe[d] one type of structurally similar antibodies" that "are not representative of the full variety or scope of the genus."). The disclosure of only one species encompassed within a genus adequately describes a claim directed to that genus only if the disclosure "indicates that the patentee has invented species sufficient to constitute the gen[us]." See Enzo Biochem, 323 F.3d at 966, 63 USPQ2d at 1615; Noelle v. Lederman, 355 F.3d 1343, 1350, 69 USPQ2d 1508, 1514 (Fed. Cir. 2004) (Fed. Cir. 2004) ("[A] patentee of a biotechnological invention cannot necessarily claim a genus after only describing a limited number of species because there may be unpredictability in the results obtained from species other than those specifically enumerated."). "A patentee will not be deemed to have invented species sufficient to constitute the genus by virtue of having disclosed a single species when … the evidence indicates ordinary artisans could not predict the operability in the invention of any species other than the one disclosed." In re Curtis, 354 F.3d 1347, 1358, 69 USPQ2d 1274, 1282 (Fed. Cir. 2004)
Satisfactory disclosure of a "representative number" depends on whether one of skill in the art would recognize that the inventor was in possession of the necessary common attributes or features possessed by the members of the genus in view of the species disclosed. For inventions in an unpredictable art, adequate written description of a genus which embraces widely variant species cannot be achieved by disclosing only one species within the genus. See, e.g., Eli Lilly, 119 F.3d at 1568, 43 USPQ2d at 1406. Instead, the disclosure must adequately reflect the structural diversity of the claimed genus, either through the disclosure of sufficient species that are "representative of the full variety or scope of the genus," or by the establishment of "a reasonable structure-function correlation." Such correlations may be established "by the inventor as described in the specification," or they may be "known in the art at the time of the filing date." See AbbVie, 759 F.3d at 1300-01, 111 USPQ2d 1780, 1790-91 (Fed. Cir. 2014) (Holding that claims to all human antibodies that bind IL-12 with a particular binding affinity rate constant (i.e., koff) were not adequately supported by a specification describing only a single type of human antibody having the claimed features because the disclosed antibody was not representative of other types of antibodies in the claimed genus, as demonstrated by the fact that other disclosed antibodies had different types of heavy and light chains, and shared only a 50% sequence similarity in their variable regions with the disclosed antibodies.). Description of a representative number of species does not require the description to be of such specificity that it would provide individual support for each species that the genus embraces.
In the instant case claimed genus of antigen-binding molecules is vast and highly variable, encompassing any antigen-binding molecule or antibody of any sequence structure or chemical formula that functions to bind to HER3 region comprising SEQ ID NOs:230 and 231. Seventeen highly homologous 10D1 antibodies fail to provide a representative number of exemplary species for the vast genus of highly structurally variable antigen-binding molecules that function as claimed. One of skill in the art could not immediately envision members of the vast genus claimed based on the disclosure of only seventeen highly homologous 10D1 antibodies.
Contrary to arguments, the decision in Rochester is relevant, and knowledge of routine screening methods to produce antibodies does not place Applicants in possession of the claimed genus of antigen-binding molecules.
MPEP 2163 states:
Conversely, describing a composition by its function alone typically will not suffice to sufficiently describe the composition. See Eli Lilly, 119 F.3 at 1568, 43 USPQ2d at 1406 (Holding that description of a gene’s function will not enable claims to the gene "because it is only an indication of what the gene does, rather than what it is."); see also Fiers, 984 F.2d at 1169-71, 25 USPQ2d at 1605-06 (discussing Amgen Inc. v. Chugai Pharm. Co., 927 F.2d 1200, 18 USPQ2d 1016 (Fed. Cir. 1991)). An adequate written description of a chemical invention also requires a precise definition, such as by structure, formula, chemical name, or physical properties, and not merely a wish or plan for obtaining the chemical invention claimed. See, e.g., Univ. of Rochester v. G.D. Searle & Co., 358 F.3d 916, 927, 69 USPQ2d 1886, 1894-95 (Fed. Cir. 2004) (The patent at issue claimed a method of selectively inhibiting PGHS-2 activity by administering a non-steroidal compound that selectively inhibits activity of the PGHS-2 gene product, however the patent did not disclose any compounds that can be used in the claimed methods. While there was a description of assays for screening compounds to identify those that inhibit the expression or activity of the PGHS-2 gene product, there was no disclosure of which peptides, polynucleotides, and small organic molecules selectively inhibit PGHS-2. The court held that "[w]ithout such disclosure, the claimed methods cannot be said to have been described.").
In the instant case, making and screening for antibodies that function as claimed is merely a wish or plan for obtaining the claimed antigen-binding molecule.
MPEP 2163 states:
For example, disclosure of an antigen fully characterized by its structure, formula, chemical name, physical properties, or deposit in a public depository does not, without more, provide an adequate written description of an antibody claimed by its binding affinity to that antigen, even when preparation of such an antibody is routine and conventional. See Amgen Inc. v. Sanofi, 872 F.3d 1367, 1378, 124 USPQ2d 1354, 1361 (Fed. Cir. 2017)("knowledge of the chemical structure of an antigen [does not give] the required kind of structure-identifying information about the corresponding antibodies"); see also Centocor Ortho Biotech, Inc. v. Abbott Labs., 636 F.3d 1341, 1351-52, 97 USPQ2d 1870, 1877 (Fed. Cir. 2011)(patent disclosed the antigen the claimed antibody was supposed to bind, but did not disclose any antibodies with the specific claimed properties).
In the instant case, knowledge of the HER3 epitope comprising SEQ ID NOs:230 and 231, even when preparation of an antibody against an epitope is routine and conventional, does not provide an adequate written description of an antibody claimed by its binding affinity to that epitope.
Maintained Rejections
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 USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms.

6. Claims 24-43 remain rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-25 of U.S. Patent No. 10,662,241 in view of WO 2012/059224, Aurisicchio, published May 2012, and WO 2008/100624, Schoebert et al.
Although the claims at issue are not identical, they are not patentably distinct from each other because the US Patent is claiming and antigen-binding molecule comprising a VH and VL region comprising the same CDR sequences instantly claimed that bind to HER3 epitope comprising SEQ ID NOs:230 and 231, a nucleic acid encoding the antigen-binding molecule, a cell expressing the antigen-binding molecule, and method of treating cancer in a subject comprising administering the antigen-binding molecule, wherein the cancer comprises cells expressing an EGFR family member, a cancer comprising cells expressing HER3, a solid tumor, breast cancer, and more, rendering obvious instant claims 24-40.

With regards to claims 41-43, the US Patent does not claim additionally administering trastuzumab or docetaxel to treat cancer.
Aurisicchio teaches monoclonal antibodies comprising VH and VL domains that bind to HER3 extracellular epitopes, including epitopes comprising instant SEQ ID NO:230 (PNPNQ), such as epitope CFGPNPNQ (SEQ ID NO: 38), FGPNPNQC (SEQ ID NO: 39), GPNPNQCC (SEQ ID NO: 40), CFGPNPNQC (SEQ ID NO: 46), FGPNPNQCC (SEQ ID NO: 47), and CFGPNPNQCC (SEQ ID NO: 53) (p. 22-23; Figure 10).
Aurisicchio teaches nucleic acids encoding the antibodies and transfecting cells to express and produce the antibodies (Examples 9, 11, and 12).
Aurisicchio teaches administering the antibodies to subjects to treat cancer including pancreatic cancer and breast cancer (Examples 6-8). Aurisicchio teaches administering the antibodies in combination with HERCEPTIN™ (trastuzumab) anti-HER2 antibody to enhance treatment of cancer (Example 8). Aurisicchio suggests treating cancer with chemotherapeutics (p. 3) and suggests combining the HER3 antibody with an anti-neoplastic agent (p. 34).
Schoebert also teaches producing therapeutic monoclonal antibodies against the HER3 extracellular domain. Schoebert also teaches compositions comprising the antibodies, nucleic acids encoding the antibodies (p. 4, 20-22, 38), and routine methods of making the antibodies by immunization of mammals, isolation of hybridoma cells producing the antibodies, isolating antibody clones from phage display, sequencing the antibodies, and transfecting cells to express the antibodies (p. 29-33; Example 1).
Schoebert teaches methods of treating cancer in a subject by administering the anti-HER3 antibody in combination with known anti-cancer agents, including docetaxel trastuzumab, and cetuximab, and treating breast and pancreatic cancer (p. 5, 22-29, 44; Example 9; claims 44-53).
It would have been prima facie obvious to one of ordinary skill in the art at the time the invention was filed to administer trastuzumab or docetaxel in the method of treating cancer claimed by the US Patent. One would have been motivated to and have a reasonable expectation of success to because: (1) the US Patent claims administering their HER3 antibody to treat cancer; (2) Aurisicchio and Schoebert suggest combining anti-cancer agents with HER3 antibody for the treatment of cancer, (3) Aurisicchio demonstrates that trastuzumab combined with anti-HER3 antibody improved therapeutic efficacy of cancer; and (4) Schoebert teaches docetaxel is a known, established chemotherapeutic for treatment of cancer and suggests combining it with anti-HER3 antibody therapy.

Philadelphia (PA): AACR; Cancer Research, 2017; 77(13 Suppl); Abstract 24) is withdrawn in view of arguments that the disclosed HMBD001 antibody is not publicly available (enabled) and the antibody is not disclosed or determined to bind HER3 epitopes SEQ ID NOs:230 and 231.
The rejection of claims under 35 U.S.C. 102(a)(1) as being anticipated by Thakker et al (European Journal of Cancer, November 13, 2018; 103S1; e36-e37; Poster Session; abstract 87) and rejection of claims under 35 U.S.C. 103 as being obvious over Thakker are both withdrawn in view of the Boyd-Kirkup declaration filed under 37 CFR 1.130 stating the exception under 102(b)(1)(A) and disqualifying Thakker as prior art.
The rejection of claims under 35 U.S.C. 102(a)(1) as being anticipated by WO 2012/059224, Aurisicchio and rejection of claims under 35 U.S.C. 103 as being obvious over Aurisicchio are withdrawn in view of claim amendments requiring the antigen-binding molecule bind to HER3 regions comprising SEQ ID NO:230 and SEQ ID NO:231. Aurisicchio does not teach or suggest their antibodies bind to both sequence regions of HER3.
16. Conclusion: No claim is allowed.
