Office Action

§112
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 . DETAILED ACTION Claims 1-20 submitted on 5/7/2026 are pending. In reply to the non-final action of 02/10/26, the applicants’ argument submitted on 5/7/2026 is acknowledged. Claims 15-18 are withdrawn. Claims 1-14 and 19-20 are for examination. Applicants’ argument submitted on 5/7/2026 is considered. Rejections and/or objections not reiterated from previous office actions are hereby withdrawn. 35 USC 112(b) Rejection The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims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. Claims 1, 5, and 2-14, 19-20 ( depend on claim 1) 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 pre-AIA the applicant regards as the invention. Claim 1 is rejected for reciting “Specifically”. It is unclear what else amino acid residue be at position 91 and 103 beside a cysteine residue those other amino acid residues are undefined. Specifically is an adverb that expresses a preference for a particular feature, but it is generally considered optional language. Under 35 U.S.C. 112(b) and MPEP 2173.05(h)(II), optional phrasing like Specifically can make a claim indefinite if it suggests an element is not required, because the “all elements” rule applies to claims. Correction is required. Claim 5 is rejected for reciting “A) a protein comprising the amino acid sequence of SEQ ID NO: 1 or SEQ ID NO: 3”. Claim 5 depends on claim 1. It is unclear how the amino acid sequence of SEQ ID NO: 1 or SEQ ID NO: 3 can have a modifying group covalently bonded to a cysteine residue at position 91 and/or position 103. Because SEQ ID NO: 1 or SEQ ID NO: 3 are unmodified and already comprise a cysteine residue at position 91 and/or position 103. It make no sense. Applicant should remove a protein comprising the amino acid sequence of SEQ ID NO: 1 or SEQ ID NO: 3 from the claim 5. Conclusion Claims 1-14 and 19-20 are rejected. No claim is allowed.
