Office Action

§DOUBLEPATENT §OTHER
DETAILED ACTION 1. The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . 2. Applicant’s amendment filed on August 12, 2026 is acknowledged. Claims 1-22, 25-29, and 50 have been canceled. Claims 23, 24, and 30-49 are pending and currently under consideration. 3. In view of applicant’s amendment, following rejections are set forth. 4. 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. 5. Claims 23, 24, and 30-49 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of US 10,723,788 (‘788 Patent) in view of Presta (US 6,727,056) for the reasons of record. Applicant’s arguments have been fully considered but have not been found persuasive. Applicant argues that the rejection is improper because this application is entitled to the safe harbor protection under 35 USC 121. Specifically, applicant asserts that during the prosecution of the ‘788 patent (matured from USSN 15/360,549), an Examiner in a restriction requirement separated isolated polynucleotide from the antibody. Thus, applicant asserts that the instant application is entitled to the safe harbor protection. This is not found persuasive for following reasons: Contrary to applicant’s reliance on an restriction requirement set forth in the prosecution history in the ‘788 Patent, note that the instant applicant and the ‘788 Patent are not related. In the footnote in page 9 of the REMARKS filed on August 12, 2026, applicant indicated that the ‘788 Patent was issued from USSN 14/933,517 which is great grandparent of the instant application. However, this is incorrect because the ‘788 Patent was issued from USSN 15/360,549, not 14/933,517. The USSN 15/360,549 (from which the ‘788 Patent is issued) is not related to the instant application. The 121 safe harbor is only applicable to patents/applications in the same 120 benefit chain as the application under examination. That is, a restriction must be in the chain of the application under examination in order for an earlier issued patent to be unavailable for a nonstatutory double patenting rejection. See Pfizer Inc. v Teva pharmaceuticals USA Inc., 86 USPQ2d 1001, at page 1008 (March 2008) and Amgen, Inc. v. F. Hoffman-La Roche Ltd., 580 F.3d 1340 (Fed. Cir. 2009), the court indicated that the prohibition under 35 U.S.C. 121 does not apply to claims in a pending case which are directed to a non-elected invention of an application and the case is not a divisional of the application. As such, the rejection is proper in spite of the restriction requirements set forth in the unrelated USSN 15/360,549 (issued as the ‘788 Patent) as the instant application was not filed as a result of the restriction requirement in the family that includes the ‘788 patent As such, applicant’s arguments have not been found persusive. 6. No claim is allowed. 7. THIS ACTION IS MADE FINAL. 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. 8.
