See MPEP § 609.05(a).
Claim Rejections - 35 USC § 103
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention.
Claims 62-65 are rejected under 35 U.S.C. 103 as being unpatentable over WO 2022125598 (published 06/16/2022, on IDS filed 03/06/2024) in view of US20210290732 (on IDS filed 03/06/2024).
WO’598 discloses SEQ ID NO: 1 (see EU-A1873 of Table 1; also known as ALT-801 or pemvidutide) has the following amino acid sequence: 1His-2Aib-3Gln-4Gly-5Thr-6Phe-7Thr-8Ser-9Asp-10Tyr-11Ser-12Lys-13Tyr-14Leu-15Asp-16Glu*- 17Lys#-18Ala-19Ala-20Lys*-21Glu-22Phe-23Ile-24Gln-25Trp-26Leu-27Leu-28Gln-29Thr-NH2, where * indicates a lactam bridge is formed between Glu16 and Lys 20, and 17Lys# indicates the attachment site for glucuronic acid C-18* (see [0031], page 7).
SEQ ID NO: 1 disclosed by WO’598 is the same as instant peptide SEQ ID NO: 1. One preferred embodiment of WO’598 is the dual agonist peptide is SEQ ID NO: 1. Another embodiment of WO’598 is a pharmaceutical formulation of SEQ ID NO: 1 in an aqueous buffer solution, referred as ALT-801. The dual agonist peptide products, including SEQ ID NO: 1, comprise an amino acid side chain amide linkage (lactam bridge), and a side chain composed of a glucuronic acid linked to a fatty acid side chain. The side chain, a surfactant comprised of a hydrophilic saccharide group covalently attached to the peptide via a linker amino acid, and a hydrophobic alkyl chain portion (see [0033], page 9).
WO’598 teaches the pharmaceutical dosage formulation comprises about 0.025-0.075% (w/w) polysorbate 20, about 0.2-0.5% (w/w) arginine, about 3-6% (w/w) mannitol in deionized water (pH 7.7 ± 0.1); optionally about 0.050% (w/w) polysorbate 20, about 0.348% (w/w) arginine, about 4.260% (w/w) mannitol in deionized water (pH 7.7 ± 0.1) (claim 24). In certain embodiments of WO’598, the pharmaceutical formulation comprises SEQ ID NO: 1 and about 0.050% (w/w) polysorbate 20, about 0.348% (w/w) arginine, about 4.260% (w/w) mannitol in deionized water (pH 7.7 ± 0.1) (see [0048], page 19).
WO’598 does not teach specifically about the formulation containing at 0.20% (w/w) polysorbate 20.
US’732 teaches in some embodiments, the dual agonist peptide can be formulated as a pharmaceutical dosage formulation comprising about 0.025-0.15% (w/w) polysorbate 20, about 0.2-0.5% (w/w) arginine, and about 3-6% (w/w) mannitol in deionized water (pH 7.7±1.0) (see [0056]).US’732 teaches formulation comprising about 0.025-0.15% (w/w) polysorbate 20, which overlaps with the presently claimed invention composition comprising about 0.20% (w/w) polysorbate 20. It would have been prima facie obvious to optimize the concentrations of all the components including polysorbate 20 before the effective filing date of the claimed invention to arrive at the pharmaceutical composition of the instantly claimed invention.
MPEP 2144.05 states: "Generally, differences in concentration or temperature will not support the patentability of subject matter encompassed by the prior art unless there is evidence indicating such concentration or temperature is critical. "[W]here the general conditions of a claim are disclosed in the prior art, it is not inventive to discover the optimum or
workable ranges by routine experimentation." In re Aller, 220 F.2d 454, 456, 105 USPQ
233, 235 (CCPA 1955)."
It further would have been obvious to one of ordinary skill in the art at the time
the invention was made to optimize the amount of each component. One would have
been motivated to do so in order to arrive at the pharmaceutical composition having same properties.. One of ordinary skill in the art would have a reasonable expectation of success since the prior art teaches a range that could guide the experimentation for the instantly claimed range of the various components of the formulation. It is noted that MPEP 2144.05 states: "In the case where the claimed ranges "overlap or lie inside ranges disclosed by the prior art" a prima facie case of obviousness exists. In re Wertheim, 541 F.2d 257, 191 USPQ 90 (CCPA 1976); In re Woodruff, 919 F.2d 1575, 16 USPQ2d 1934 (Fed. Cir. 1990); In re Geisler, 116 F.3d 1465, 1469-71, 43 USPQ2d 1362, 1365-66 (Fed. Cir. 1997). Similarly, a prima facie case of obviousness exists where the claimed ranges or amounts do not overlap with the prior art but are merely close. Titanium Metals Corp. of America v. Banner, 778 F.2d 775, 783, 227 USPQ 773, 779 (Fed. Cir. 1985). (Court held as proper a rejection of a claim directed to an alloy of "having 0.8% nickel, 0.3% molybdenum, up to 0.1% iron, balance titanium" as obvious over a reference disclosing alloys of 0.75% nickel, 0.25% molybdenum, balance titanium and 0.94% nickel, 0.31% molybdenum, balance titanium. "The proportions are so close that prima facie one skilled in the art would have expected them to have the same properties”. See MPEP § 2144.05.
Regarding claim 62, US’732 teaches the pharmaceutical dosage formulation according to any preceding aspect, the formulation comprising about 0.025-0.15% (w/w) polysorbate 20 or polysorbate 80, about 0.2-0.5% (w/w) arginine, about 3-6% (w/w) mannitol in water (pH 7.7±1.0); optionally about 0.050% (w/w) polysorbate 20, about 0.35% (w/w) arginine, about 4.3% (w/w) mannitol in water (pH 7.7±1.0) (see [0138]).
Regarding claims 63 and 65, WO’598 teaches a method of administration of ALT-801 (Pemvidutide) across the different dose groups (1.2 mg, 1.8 mg and 2.4 mg) (see Figure 2, [0016], page 4). WO’598 teaches about a pharmaceutical dosage formulation comprising about 1.2 mg SEQ ID NO: 1 (claim 27).
Regarding claim 64, WO’598 teaches about the therapeutic effective amount of the pharmaceutical dosage formulation comprising SEQ ID NO: 1 is about 1.8 mg of SEQ ID NO: 1 (claim 32).
Therefore, the presently claimed invention was prima facie obvious to one of ordinary skill in the art at the time of the effective filing date.
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.

Claims 62-65 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 8, and 9 of U.S. Patent No. 12171806 in view of WO 2022125598 (on IDS filed 03/06/2024), and US20210290732 (on IDS filed 03/06/2024).
Although the claims at issue are not identical, they are not patentably distinct from each other because claims 1, 8, and 9 of the US‘806 recite the same SEQ ID NO:1 and the overlapping range of components of the composition of the instantly claimed invention.
US‘806 claims therapeutic effective amount of a pharmaceutical dosage formulation comprising SEQ ID NO: 1 (claim 1), wherein the pharmaceutical dosage is an aqueous formulation comprising one or more of polysorbate 20, arginine, or mannitol (claim 8). US’806 specifically claims the pharmaceutical dosage formulation comprises about 0.025-0.075% (w/w) polysorbate 20, about 0.2-0.5% (w/w) arginine, about 3-6% (w/w) mannitol in deionized water (pH 7.7±0.1); optionally about 0.050% (w/w) polysorbate 20, about 0.348% (w/w) arginine, about 4.260% (w/w) mannitol in deionized water (pH 7.7±0.1) (claim 9).
SEQ ID NO: 1 (EU-A1873 of Table 1; also known as ALT-801 or pemvidutide) claimed by US‘806 is the same amino acid sequence of the instantly claimed SEQ ID NO:1 present in the pharmaceutical composition.
The US‘806 differs from the instant claims in that they do not claim exact amount of SEQ ID NO:1 present in the composition from those recited in instant claims 63-65. The therapeutic effective amount of a pharmaceutical dosage formulation comprising SEQ ID NO: 1 of claim 1 of US’806 is the same as instant peptide SEQ ID NO: 1, wherein as read in light of the specification where the administration of ALT-801 (also referred to herein as pemvidutide) at a dose of 1.2 mg, 1.8 mg and 2.4 mg (see col 3, line 67 – col 4 line 2; Figure 2; Table 10).
The US‘806 also differs from the instant claims in that they do not claim that the amount of polysorbate 20 in the pharmaceutical composition is 0.20% (w/w) from those recited in instant claim 1.
The teachings of WO’598 and US’732 are discussed above.
It would have been prima facie obvious to one of ordinary skill in the art to have modified the therapeutic effective amount of a pharmaceutical dosage formulation comprising SEQ ID NO: 1 claimed by US’806 to substitute with dose of 1.2 mg, 1.8 mg and 2.4 mg, as disclosed by WO’598. An ordinarily skilled artisan would have had a reasonable expectation of success by modifying pharmaceutical dosage formulations comprising an agonist peptide product (e.g., SEQ ID NO: 1) and about 0.025-0.15% (w/w) polysorbate 20, about 0.2-0.5% (w/w) arginine, about 3-6% (w/w) mannitol in deionized water (pH 7.7 ± 0.1) (see [0138]) as taught by US’732 to an alternative dual agonist peptide formulation comprising polysorbate 20 before the effective filing date of the claimed invention to arrive at the pharmaceutical composition of the instantly claimed invention. It would have been prima facie obvious for one of ordinary skill in the art to modify the teachings of US’598 to effectively change the amount of polysorbate 20 ( 0.20% w/w)to achieve a pharmaceutical composition comprising SEQ ID NO:1.
Claims 62-65 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 6, 17, 19, 41 and 67 of Application No. 18/467608.
Claims 62-65 of this application are patentably indistinct from claims 1, 6, 17, 19, 41 and 67 of co-pending Application No. 18/467608.
Claims 1, 6, 17, 19, 41and 67 of the co-pending application recite a method comprising administering pemvidutide once weekly in an amount from at least about 1.2 mg to about 2.4 mg (see claim 1); wherein the pemvidutide is administered once weekly in an amount of 2.4 mg (see claim 6); weekly dosing of about 1.8 mg pemvidutide (see claim 17).
The claims 1, 6, 17, 19, 41and 67 of the ‘608 application differ from the instantly claimed invention in that the ‘608 application includes method of reducing body weight in a human being with fatty liver disease.
As both sets of claims recite regarding composition of ALT-801 or pemvidutide, even though they are not exactly matching, they are overlapping in scope. Thus rendering one set of claims to be unpatentable.
This is a nonstatutory double patenting rejection.
Claims 62-65 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 3, 40, 42, 43, and 46 of Application No. 19/076984.
Claims 62-65 of this application are patentably indistinct from claims 3, 40, 42, 43, and 46 of co-pending Application No. 19/076984.
Claims 3, 40, 42, 43, and 46 of the co-pending application recite a method for treatment comprising, administering to the human being a once weekly therapeutically effective amount of a pharmaceutical dosage formulation comprising at least 1.2 mg and up to 2.4 mg of a peptide product according to SEQ ID NO: 1 or peptide product that is at least 80% identical to a peptide of SEQ ID NO: 1 (see claims 3 and 40); wherein the peptide product is at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98% or at least 99% identical to a peptide of SEQ ID NO: 1 (see claim 42); wherein the peptide product is 100% identical to a peptide of SEQ ID NO: 1 (see claim 43); and wherein the pharmaceutical dosage formulation comprises about 0.025-0.5% (w/w) polysorbate 20, about 0.2-0.5% (w/w) arginine, and about 3-6% (w/w) mannitol in water (pH 7.7 ± 0.1) (see claim 46).
The claims 3, 40, 42, 43, and 46 of the ‘984 application differ from the instantly claimed invention in that the ‘984 application includes method for treatment of chronic weight management and reducing serum lipids.
As both sets of claims recite regarding composition of GLP-1R and GCGR agonist pemvidutide (a composition comprising SEQ ID NO.: 1), even though they are not exactly matching, they are overlapping in scope. Thus rendering one set of claims to be unpatentable.
This is a nonstatutory double patenting rejection.
Claims 62-65 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 40, 45, 46, 47, 53, and 54 of Application No. 18/943449.
Claims 62-65 of this application are patentably indistinct from claims 40, 45, 46, 47, 53, and 54 of co-pending Application No. 18/943449.
Claims 40, 45, 46, 47, 53, and 54 of the co-pending application recite a method for treatment comprising administering to the human being once weekly therapeutic effective amount of a pharmaceutical dosage formulation comprising SEQ ID NO: 1 (see claims 40); wherein the pharmaceutical dosage is an aqueous formulation comprising one or more of polysorbate 20, arginine, or mannitol (see claim 45); wherein the pharmaceutical dosage formulation comprises polysorbate 20, about 0.2-0.5% (w/w) arginine, and about 3-6% (w/w) mannitol in water (pH 7.7 ± 0.1) (see claim 46); wherein the pharmaceutical dosage formulation comprises about polysorbate 20, about 0.348% (w/w) arginine, about 4.260% (w/w) mannitol in water (pH 7.7 ± 0.1) (see claim 47); and comprising administering to the human being a once weekly therapeutic effective amount of a pharmaceutical dosage formulation comprising SEQ ID NO: 1, polysorbate 20, about 0.348% (w/w) arginine, about 4.260% (w/w) mannitol in water (pH 7.7 ± 0.1) (see claim 54).
The claims 40, 45, 46, 47, 53, and 54 of the ‘449 application differ from the instantly claimed invention in that the ‘449 application includes method to reduce excess body weight and maintain weight reduction in treatment of chronic weight management, reduce liver fat, and lower blood glucose.
As both sets of claims recite regarding composition of GLP-1R and GCGR agonist ALT-801 (Pemvidutide), even though they are not exactly matching, they are overlapping in scope. Thus rendering one set of claims to be unpatentable.
This is a nonstatutory double patenting rejection.
