Office Action

§102 §112 §DP
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 . Election/Restriction Applicant's election with traverse of Group I, claim(s) 1-9 in the reply filed on 06/29/2026 is acknowledged. The traversal is on the ground(s) that the amended claims are not read upon by DuPont, and thus, there is unity of invention. This is not found persuasive because the linear polymer is known in the prior art, as cited in the following rejections below and incorporated herein, and thus, the linear polymer is not a special technical feature as it does not make a contribution over the prior art The requirement is still deemed proper and is therefore made FINAL. Claims 10, 11, 13-17, 19-21, and 23, are withdrawn from further consideration pursuant to 37 CFR 1.142(b), as being drawn to a nonelected invention, there being no allowable generic or linking claim. Applicant timely traversed the restriction (election) requirement in the reply filed on 06/29/2026. Double Patenting The nonstatutory double patenting rejection is based on a judicially created doctrine grounded in public policy (a policy reflected in the statute) so as to prevent the unjustified or improper timewise extension of the “right to exclude” granted by a patent and to prevent possible harassment by multiple assignees. A nonstatutory double patenting rejection is appropriate where the conflicting claims are not identical, but at least one examined application claim is not patentably distinct from the reference claim(s) because the examined application claim is either anticipated by, or would have been obvious over, the reference claim(s). See, e.g., In re Berg, 140 F.3d 1428, 46 USPQ2d 1226 (Fed. Cir. 1998); In re Goodman, 11 F.3d 1046, 29 USPQ2d 2010 (Fed. Cir. 1993); In re Longi, 759 F.2d 887, 225 USPQ 645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ 761 (CCPA 1982); In re Vogel, 422 F.2d 438, 164 USPQ 619 (CCPA 1970); In re Thorington, 418 F.2d 528, 163 USPQ 644 (CCPA 1969). A timely filed terminal disclaimer in compliance with 37 CFR 1.321(c) or 1.321(d) may be used to overcome an actual or provisional rejection based on nonstatutory double patenting provided the reference application or patent either is shown to be commonly owned with the examined application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. See MPEP § 717.02 for applications subject to examination under the first inventor to file provisions of the AIA as explained in MPEP § 2159. See MPEP § 2146 et seq. for applications not subject to examination under the first inventor to file provisions of the AIA . A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b). The filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13. The USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms. The actual filing date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AIA /25, or PTO/AIA /26) should be used. A web-based eTerminal Disclaimer may be filled out completely online using web-screens. An eTerminal Disclaimer that meets all requirements is auto-processed and approved immediately upon submission. For more information about eTerminal Disclaimers, refer to www.uspto.gov/patents/apply/applying-online/eterminal-disclaimer. Claim 1-9 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claims 7-12 of copending Application No. 18/852,980 (App. No. 18/852,980). Although the claims at issue are not identical, they are not patentably distinct from each other because App. No. 18/852,980 teaches each and every component and reads upon the claims in an anticipatory manner. Regarding claims 1-9, App. No. 18/852,980 teaches a conjugated polymer having the repeating structure of formula PNG media_image1.png 93 138 media_image1.png Greyscale , wherein Ar is an arylene or heteroarylene group, p is at least 1, one of Y1 or Y2 is CR1, wherein R1 is H, the other Y1 and Y2 is N. (claim 7), wherein p is also 2-5 (claim 8), Ar is p-phenylene (claim 9), wherein one of the substituents of Ar is F (claim 10), and specifically, the formula is PNG media_image2.png 385 368 media_image2.png Greyscale (claim 12). This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. Claims 1-2 are provisionally rejected on the ground of nonstatutory double patenting as being unpatentable over claim 6 of copending Application No. 18/284,850 (App. No. 18/284,850). Although the claims at issue are not identical, they are not patentably distinct from each other because App. No. 18/284,850 teaches each and every component and reads upon the claims in an anticipatory manner. Regarding claims 1-2, App. No. 18/284,850 teaches a conjugated polymer with the repeating unit of formula PNG media_image3.png 65 135 media_image3.png Greyscale , wherein Ar is an arylene or heteroarylene group, p is at least 1, one of Y1 and Y2 is CR7, and the other Y1 and Y2 is N. (claim 6). This is a provisional nonstatutory double patenting rejection because the patentably indistinct claims have not in fact been patented. 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. Claim 9 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 applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. Claim 9 recites the repeating units of formulae (II to IV), however “Y1,” “Y2,” “Ar,” and “p,” are not defined. It is unclear whether they are defined by the same definitions as in claim 1 or by another definition. Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 1-7 and 9, is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by US 2010/0041862 A1 to Li (hereinafter Li). Regarding claims 1-7 and 9, Li teaches a semiconducting polymer having the formula PNG media_image4.png 152 317 media_image4.png Greyscale (para 6), wherein a and b are 0 to 10, n is 2 to 5000, (para 7-11), and specifically, the formula is PNG media_image5.png 122 321 media_image5.png Greyscale , wherein R3 is an alkyl groups, (para 12-13), such as C1-C20 alkyl groups, (para 13), which meets the claimed linear polymer wherein Ar is heteroarylene groups of thiophene, p=4, Y1 is N, and Y2 is -CH- of claims 1-7. Li also teaches the semiconducting polymer can have the formula PNG media_image6.png 99 301 media_image6.png Greyscale , which appears to meet the claimed formula (II) in claim 9, wherein q is 1 and p does not appear to be defined.
