Office Action

§DP
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 . Detailed Action This Office Action is in response to the Applicant’s reply received 7/17/24. Claims 1-35 are pending and considered on the merits. 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 1-35 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-25 of U.S. Patent No. 11746325. Although the claims at issue are not identical, they are not patentably distinct from each other because both sets of claims disclose a method of treating a hematological disease, which includes aplastic anemia by administering a combination of cells comprising i) ex vivo cultured CD133+/CD34+ cells and ii) a second CD133-/CD34- cell fraction of umbilical cord blood that has been cryopreserved then thawed prior to administration (compare claim 1 from both sets). While the current claims treats aplastic anemia, this falls into the broader scope of “hematological disease” (US’325, col 29, lines 30-40). Free of the Prior Art This Application is a CON of 11746325 (US App # 16614057) and is free of the art for similar reasons. The closest prior art is Peled et al. (US 2012/0141434, in IDS 9/30/24) in combination with Ebner et al. (transplantation in Hematology and Oncology II, in IDS 9/30/24). Peled et al. teaches a method similar to claim 8 for selecting and transplanting either CD34+ or CD133+ cells ([0052], [0085]). Ebner et al. teach CD34+/CD133+ cells are an alternative to CD34+ selection to cell transplantation for leukemia treatments (last three paragraphs). However it is not known to combine expanded CD34+/CD133+ cells with CD133-/CD34- cell fractions for transplantation. And when reading both pieces of prior art, this combination does not seem to be advantageous or even advised for cell transplantation to treat hematological disease since significant effort is placed on purging CD133-/CD34- cells. In response to this office action the applicant should specifically point out the support for any amendments made to the disclosure, including the claims (MPEP 714.02 and 2163.06).
