5. Applicant’s arguments filed on October 03, 2025 have been fully considered but they are not deemed to be persuasive for the reasons set forth below.
Claim Rejections - 35 USC § 112
The following is a quotation of 35 U.S.C. 112(b):
(b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention.
The following is a quotation of 35 U.S.C. 112 (pre-AIA ), second paragraph:
The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the applicant regards as his invention.
6. Claims 1-3, 6-11, 14-20, 22, 23, 27 and 31-45 are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention.
Independent claims 1 and 35-37 recite limitation “wherein the patient’s chronic pain, anxiety and/or depression is reduced after administration of the LEPR agonist as determined by a reduction in a Patient Health Questionnaire-9 (PHQ-9) score and/or an improvement in Short Form-36 Health Questionnaire (SF-36) SF36 score.” Revised MPEP 2173.05(g) states: “the use of functional language in a claim may fail ‘to provide a clear-cut indication of the scope of the subject matter embraced by the claim' and thus be indefinite.” It further states: “Examiners should consider the following factors when examining claims that contain functional language to determine whether the language is ambiguous: (1) whether there is a clear cut indication of the scope of the subject matter covered by the claim; (2) whether the language sets forth well-defined boundaries of the invention or only states a problem solved or a result obtained; and (3) whether one of ordinary skill in the art would know from the claim terms what structure or steps are encompassed by the claim.” In the instant case, claims recite a method of treatment but then define the outcome of the treatment protocol by functional language—reduction of symptoms as determined by Health Questionnaires. While a functional limitation can provide a patentable distinction (limit the claim scope) by imposing limits on the function of a structure, material or action, in the instant case it is unclear what material/structural or manipulative differences are encompassed by a questionnaire that is employed to evaluate the desired clinical effect. Since the claims fail to meet the criteria set forth in MPEP 2173.05(g), then the claims are rejected as being indefinite. This affects all depending claims.
Applicant is advised that one of the purposes of the 112, second paragraph is to provide a clear warning to others as to what constitutes infringement of the patent (see, e.g., Solomon v. Kimberly-Clark Corp., 216 F.3d 1372, 1379, 55 USPQ2d 1279, 1283 (Fed. Cir. 2000). The test for definiteness under 35 U.S.C. § 112, second paragraph, is whether “those skilled in the art would understand what is claimed when the claim is read in light of the specification.” Orthokinetics, Inc. v. Safety Travel Chairs, Inc., 806 F .2d 1565 (Fed. Cir. 1986) (citations omitted).
In precedential decision Ex parte Kenichi Miyazaki, Appeal 2007-330, BPAI stated “In particular, rather than requiring that the claims are insolubly ambiguous, we hold that if a claim is amendable to two or more plausible claim constructions, the USPTO is justified in requiring the applicant to more precisely define the metes and bounds of the claimed invention by holding the claim unpatentable under 35 U.S.C. § 112, second paragraph.”
Further, the federal Circuit stated in Halliburton Energy Servs.:
When a claim limitation is defined in purely functional terms, the task of determining whether that limitation is sufficiently definite is a difficult one that is highly dependent on context (e.g., the disclosure in the specification and the knowledge of a person of ordinary skill in the relevant art area). We note that the patent drafter is in the best position to resolve the ambiguity in the patent claims, and it is highly desirable that patent examiner demand that applicants do so in appropriate circumstances so that the patent can be amended during prosecution rather than attempting to resolve the ambiguity in litigation.
Halliburton Energy Servs. V. M-ILLC 514 F .3d 1244, 1255 (Fed. Cir. 2008) (emphasis added).
Claim Rejections - 35 USC § 102
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 the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
7. Claim(s) 1-3, 6-11, 14-20, 22, 23, 27 and 31-45 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 2029/0309079, 2019, the ‘079 document, for reasons of record in section 12 of Paper mailed on April 01, 2024, section 5 of Paper mailed on October 28, 2024, section 6 of Paper mailed on February 28, 2025 and section 11 of Paper mailed on July 03, 2025.
Claims 1-3, 6-11, 14-20, 22, 23, 27 and 31-45 encompass methods of clinical administration of LEPR agonist antibody, specifically H4H17319P2 (mibavademab), to a patient with lipodystrophy to prevent or reduce chronic pain, anxiety and/or depression. The ‘079 document fully teaches treatment of lipodystrophy by administration of LEPR agonist antibody H4H17319P2, [0037] and [0160], which is the same antibody as in present claims, mibavademab. The doses recited within [0159]-[0160] are compatible with the doses in claims 40-45. Thus, by practicing the administration of mibavademab, full prevention of the symptoms recited within the instant claims has been achieved, absence evidence to the contrary. Next, when practicing the administration of mibavademab to treat lipodystrophy, reduction of pain, anxiety and/or depression in those patients suffering from these conditions as well as various symptoms related to and associated with these pathologies, have been achieved as well.
“The inherent teaching of a prior art reference, a question of fact, arises both in the context of anticipation and obviousness.” In re Napier, 55 F.3d 610, 613, 34 USPQ2d 1782, 1784 (Fed. Cir. 1995) (affirmed a 35 U.S.C. 103 rejection based in part on inherent disclosure in one of the references). See also In re Grasselli, 713 F.2d 731, 739, 218 USPQ 769, 775 (Fed. Cir. 1983). See also MPEP 2112 [R-3], which states that under 35 U.S.C. 102 or 103, a prior art disclosure can be express, implicit or inherent.
“The discovery of a previously unappreciated property of a prior art composition, or of a scientific explanation for the prior art’s functioning, does not render the old composition patentably new to the discoverer.” Atlas Powder Co. v. Ireco Inc., 190 F.3d 1342, 1347, 51 USPQ2d 1943, 1947 (Fed. Cir. 1999). Thus, the claiming of a new use, new function or unknown property which is inherently present in the prior art does not necessarily make the claim patentable. In re Best, 562 F.2d 1252, 1254, 195 USPQ 430, 433 (CCPA 1977).
For reasons of record fully explained earlier and reasons above, the rejection is maintained.
