Office Action

§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 . Amendments Applicants amendments to the claims filed 6/9/2026 have been entered. Response to Arguments Applicant’s arguments, see Remarks, filed 6/9/2026, with respect to the obviousness rejections over Matsumoto alone, and in combination with Topala, Leng, Peng and Powell have been fully considered and are persuasive. The obviousness rejections of claims 32-34,36-41 and 44 has been withdrawn. Claim Objections Claims 39-41 are objected to because of the following informalities: it is redundant to recite the protein is selected from an intracellular protein as this limitation is already recited in claim 33, from which these claims depend upon. Appropriate correction is required. Applicants amendment to claim 33 necessitated this new objection. 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. Claims 44 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. Regarding claim 44, the limitation that the protein is a full length antibody or fragment thereof, does not agree with claim 33 from which it depends. Antibodies are extracellular proteins not intracellular proteins as required in claim 33. This new rejection was necessitated by amendment of claim 33. Conclusion Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
