Office Action

§101 §102 §103 §112
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 . 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. Election/Restrictions Applicant’s election without traverse of group II (peptides) and Omicsynin B6 in the reply filed on 6 Jan, 2026 is acknowledged. Applicants have elected Omicsynin B6. A search was conducted for this invention, and a reference was found that anticipated this claim. As a result, claim 4 was examined and claims 1, 5, 6, 8, and 9 were withdrawn from consideration. Claims Status Claims 1, 4-6, 8, and 9 are pending. Claims 1, 5, 6, 8, and 9 have been withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention or species, there being no allowable generic or linking claim. Election was made without traverse in the reply filed on 6 Jan, 2026. Specification The disclosure is objected to because of the following informalities: the table on p4 of the spec includes a Chinese character. All documents must be in English, or, if originally in a foreign language, must have a certified English language translation (37 CFR 3.26). Appropriate correction is required. Drawings The drawings are objected to because fig 21 is not in English. Documents submitted for examination must be in English, or, of originally in a foreign language, must have a certified translation (37 CFR 3.26). Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Claim Rejections - 35 USC § 101 35 U.S.C. 101 reads as follows: Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title. Claim 4 is rejected under 35 U.S.C. 101 because it reads on a judicial exception (natural phenomenon). The Supreme Court has given a 3 part test for patent eligibility: 1) Is the claim drawn to a process, machine, manufacture, or composition of matter? 2a) If the first test is passed, does a judicial exception apply? 2b) If a judicial exception applies, is there something beyond the judicial exception? Applying the test: Applicants are claiming peptides, a composition of matter. 2a) Applicants isolated their sequences from Streptomyces CPPC200451 (example 2, p15, line 37-p18, line 10); this bacterium was isolated from soil (p2, 6th paragraph). This means that the peptides are produced by a naturally occurring organism, and would reasonably be expected to be produced in nature. 2b) The claim can be met with just the peptides. As there is nothing else in this embodiment, there can be no feature beyond the natural product. Thus, the claim lacks eligibility. Claim Rejections - 35 USC § 112(b) 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. Claim 4 is 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. Claim 4 requires a “group” of Omicsynins, but it is not clear if this is one of the peptides, all of the peptides, or a subset of the peptides described in the claim. If it allows for a subset of the peptides, but not just one, it is not clear how many are required to be a “group” of peptides. Claim Rejections - 35 USC § 102 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. Claim(s) 4 is rejected under 35 U.S.C. 102(a)(1) as being anticipated by Kido et al (US 4,526,866). Kido et al discuss isolating compounds produced by Streptomyces 1647 P-2 strain (column 1, line 37-38). The material was cultured, then peptides isolated with a cation exchange resin and size exclusion chromatography to get a crude mixture, then purified by HPLC (column 3, line 19-43). While the reference does not discuss the specific sequences claimed by applicants, they are isolating compounds from the same species as applicants isolated their peptides from, using a similar method (isolation from culture medium), so they will inherently be present. Claim Rejections - 35 USC § 103 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. Claim(s) 4 is rejected under 35 U.S.C. 103 as being unpatentable over Nakae et al (J. Antibiotics (2010) 63 p41-44). Nakae et al mention antipain, a compound identical to applicant’s elected species, save that position R2 is an isopropyl instead of an isobutyl group (fig 1a). However, applicant’s elected species is an obvious variant (MPEP 2144.09(II)), rendering obvious claim 4.
