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 Status of Application, Amendments, and/or Claims Applicant's amendment filed on 12/15/2025 has been entered. Claims 75-76 and 78-85 are pending. Claims 83-85 are currently under consideration. Claims 75-76 and 78-82 82 are withdrawn from further consideration pursuant to 37 CFR 1.142(b) as being drawn to a nonelected invention. Withdrawn Objections and/or Rejections The rejections of claims 83-85 under 35 U.S.C. 112(a) for new matter and written description are withdrawn in view of amended claims. Information Disclosure Statement The information disclosure statement filed on 12/15/2025 has been considered by the Examiner. Claim Rejections under 35 USC § 112 (b) (i). The following is a quotation of the second paragraph of 35 U.S.C. 112: 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. (ii). Claims 83-85 are rejected under 35 U.S.C. 112(b) as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor regards as the invention. This is a new ground of rejection necessitated by Applicant's amendment. Claim 83 is directed to a method for making a pharmaceutical composition. However, neither the preamble nor the body of the claim identifies the specific antibody or antigen-binding fragment to be included in the pharmaceutical composition. Instead, the claim recites a method of formulating a pharmaceutical composition using an unidentified antibody selected through screening. Furthermore, the claim fails to specify the plurality of candidate antibodies and provides only functional criteria without reciting the substantive steps required to perform the screening. Accordingly, claims 83–85 are rejected under 35 U.S.C. 112 for lack of definiteness. Conclusion No claims are allowed. Advisory Information 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 extension fee 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 date of this final action.
