Office Action

§DOUBLEPATENT
DETAILED ACTION Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. Claims 27-35 are pending as of the preliminary amendment of 12/5/23, and are considered herein. Claim Objections Applicant is advised that should claim 27 be found allowable, claim 33 will be objected to under 37 CFR 1.75 as being a substantial duplicate thereof. When two claims in an application are duplicates or else are so close in content that they both cover the same thing, despite a slight difference in wording, it is proper after allowing one claim to object to the other as being a substantial duplicate of the allowed claim. See MPEP § 608.01(m). Claim 33 is to culturing the monolayer obtained in Claim 27, step C. However, the monolayer claimed is already being cultured, in Claim 27, step C. Thus, despite a slight difference in wording these claims have substantially the same scope. 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 27-35 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-9 of U.S. Patent No. 9,730,962. Although the claims at issue are not identical, they are not patentably distinct from each other because: Claim 27: Claim 1 of the patent teaches culturing RPE cells in the presence of basic FGF (which an FGF), the cells losing pigmentation and epithelial morphology (step b), and the cells obtained (Applicant’s step b) are then cultured in the absence of bFGF (step c), and it is presumed, as the steps are performed, the same characteristics are obtained. Claim 28: Claim 5 requires the obtained monolayer to have cells with the same expressed proteins. Claim 29: Claim 6 requires the absence of cells expressing at least one of the same marker Markush, indicating that all four markers may be non-expressed. Claim 30: Claim 7 teaches further isolating the cells produced. Claim 31: Claim 8 teaches the cells may be further provided a matrix or substrate. Claim 32: Claim 9 teaches the cells may be provided in a suspension. Claim 33: As noted in the double patenting warning, the claim limitation does not alter the scope of Claim 27. Thus, it is taught. Also, Claim 1, step d teaches repeating steps b-c. Claim 34: Claim 1, step c, teaches the absence of bFGF. Claim 35: Claim 1, step c teaches culturing the subsequent culture of the non-pigmented cells lacking epithelial morphology, in the absence of bFGF, in step c. Thus, in light of the patent, the invention is obvious. The Artisan would do so, and expect success, as it is claimed. Claims Free of the Art The claims are free of the prior art of record. No art suggests the bFGF dedifferentiation of these cells, then redifferentiation of the same. Simiarly, this agrees with the NSDP rejections above. Conclusion No claim is allowed.
