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 .
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 and 4-14 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.
The claims had been rejected on the basis that claim 1 had defined diamine units (X) first as containing 6 to 10 carbon atoms, and then as containing 9 carbon atoms thus casting doubt on how many carbon atoms were permitted in this particular structural attribute. Applicant has clarified in their remarks an aim to disclose a requirement that the polyamide be derived from aliphatic diamines having to 6 to 10 carbon atoms, but wherein at least some non-zero fraction of the diamine has exactly 9 carbon atoms. While the Examiner appreciates that Applicant has acknowledged on the record their intended meaning, the claim language should still be modified to properly reflect these intentions.
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.
Claims 1, 4, and 6-14 are rejected under 35 U.S.C. 103 as being unpatentable over Joel et al., WO 2021/037850.
The salient teachings of Joel are the same as those summarized in the February 25, 2026 Office communication. Whereas the indicated amount of C9-12 diamine monomer with 2-3 carbon branches at the 2-position employed in the preparation of the prior art polyamides (25-45 mol%) had previously overlapped the corresponding claimed range, Applicant has since amended the range defining the amount of diamine unit (X) so that it instead abuts the prior art range. However, “ a prima facie case of obviousness exists where the claimed ranges and prior art ranges do not overlap but are close enough that one skilled in the art would have expected [the claimed product and a product disclosed in the prior art] to have the same properties.” Titanium Metals Corp. of America v. Banner, 778 F.2d 775, 227 USPQ 773 (Fed. Cir. 1985). To the extent that the amended range may include quantities as high as, for example, 24.99 mol% of diamine units obtained from 2-ethyl-1,7-diaminoheptane, a skilled practitioner of the prior art invention would have a reasonable expectation that any properties of the polyamide influenced by the presence of these units would not be significantly altered.
Double Patenting
Claims 1, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 13 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, and 15 of copending Application No. 18/721,481 (reference application) for the reasons outlined previously.
This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented.
Allowable Subject Matter
Claim 5 would be allowable if rewritten to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action and to include all of the limitations of the base claim and any intervening claims.
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.
