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 . Claims 1-13, 16 and 17 are pending in the application. This action is in response to applicants' amendment dated February 6, 2026. Claims 1, 3, 4, 8 and 16 have been amended. Response to Amendment Applicant's arguments filed February 6, 2026 have been fully considered with the following effect: The applicants’ amendments are sufficient to overcome the improper Markush rejection, labeled paragraph 1) in the last office action, which is hereby withdrawn. The applicants’ amendments are sufficient to overcome the 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph rejection, labeled paragraph 4) in the last office action, which is hereby withdrawn. The applicant's amendments and arguments are sufficient to overcome the 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph rejections, labeled paragraph 5a), b), c), d), e), f), g), h), i), j) and k) in the last office action, which are hereby withdrawn. In view of the amendment dated February 6, 2026, the following new grounds of rejection apply: 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 1-13, 16 and 17 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 pre-AIA the applicant regards as the invention. The following reasons apply: Claim 1 and claims dependent thereon are vague and indefinite in that it is not known what is meant by the period that appears after the definition of HET. 608.01(m) Form of Claims [R - 3] The claim or claims must commence on a separate sheet and should appear after the detailed description of the invention.< While there is no set statutory form for claims, the present Office practice is to insist that each claim must be the object of a sentence starting with "I (or we) claim", "The invention claimed is" (or the equivalent). If, at the time of allowance, the quoted terminology is not present, it is inserted by the clerk. Each claim begins with a capital letter and ends with a period. Periods may not be used elsewhere in the claims except for abbreviations. See Fressola v. Manbeck, >36 USPQ2d 1211< (D.D.C. 1995). ** >Where a claim sets forth a plurality of elements or steps, each element or step of the claim should be separated by a line indentation, 37 CFR 1.75(i). Claim 1 and claims dependent thereon are vague and indefinite in that it is not known what is meant by the definition of R4a where R4a forms a group selected from the group consisting of =O, =S, =CRbRc, =NRc, and =NNRcRc. R4a is monovalent and this definition is divalent. 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.
