Office Action

§102 §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 . 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, 5, and 6 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Schneider et al. (ACS Combinatorial Science, 2017). The instant claims are drawn to a peptoid compound having a structure of formula (I) as shown in the claims. Schneider et al. discloses a compound designated #92 (page 726) that anticipates the instant claims when n=1, R1 = hydroxyethyl and R2= C11 alkyl, in the compound of instant formula (I). 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. Claims 1-12, 102, 103, 112, and 114 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 8, 9, and 10-13 of U.S. Patent No. 12,102,675. Although the claims at issue are not identical, they are not patentably distinct from each other because the ‘675 patent contains claims that are drawn to a composition comprising mRNA, which is a polyanionic compound, encapsulated with a delivery vehicle that may be a peptoid compound of formula (I). The composition claimed in the ‘675 patent may be used as a vaccine or may be administered to treat cancer of viral infections. The disclosure of a compound of formula (I) in the composition claimed in the reference patent, as well as the fact that the composition may be used as a vaccine or to treat cancer or viral infections, renders the instant claims obvious. Claims 1-12 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 6, and 7 of U.S. Patent No. 12,011,478. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims of the ‘478 patent recite a composition that comprises a delivery vehicle that includes a peptoid of formula (I). The disclosure of the peptoid compound of the present invention in the composition recited in the claims of the ‘478 patent renders the instant claims obvious of the claims in the reference patent. Claims 1-12, 15, 50, 107, and 110 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1, 3-6, 10, 12, 14, 15, and 17-26 of U.S. Patent No. 11,446,394. Although the claims at issue are not identical, they are not patentably distinct from each other because the claims in the reference patent recite a composition that comprises a cationic peptide that encompasses the compound of instant formula (I), and may include phospholipids, a polyanionic compound, and PEG lipids, and according to the reference patent, the composition may be used as a delivery vehicle for delivering a polyanionic compound to a cell. The claims of the reference patent therefore render the instant claims obvious.
