Office Action

§DP
DETAILED ACTION This Office action is in response to a non-provisional utility patent application filed by Applicant on 5/1/2025. 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 . Information Disclosure Statement PTO-1449 The Information Disclosure Statement submitted by applicant on 5/1/2025 has been considered. The submission is in compliance with the provisions of 37 CFR § 1.97. Form PTO-1449 signed and attached hereto. 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 1–9 rejected on the ground of nonstatutory obviousness-type double patenting as being unpatentable over claims 1 and 8 of US 21,316,620 B1, issued May 27, 2025. Although the claims at issue are not identical, they are not patentably distinct from each other. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: Nix (US 11,153,080 B1, issued Oct. 19, 2021), secure communication sessions between client and server using multiple post-quantum cryptography key encapsulation algorithms and includes generating an ephemeral public key for the device and using encapsulation to generate a first shared secret and a first ciphertext; Chikara (US 2025/0016140 A1, published Jan. 9, 2025), using a public key with an encryption encapsulation algorithm to generate a session key and a cipher text; O’Connell (US 2023/0247010 A1, Aug. 3, 2023), creating a shared secret using a post-quantum encryption key encapsulation module and randomly generates ephemeral static key and an ephemeral public key; Cap (US 2023/0353349 A1, published Nov. 2, 2023), a quantum secure layer using long-term public/private key pair encapsulation mechanism to send ephemeral keys by the server to establish a master shared secret; and Watson (US 2024/0235842 A1, published Jul. 11, 2024), key encapsulation mechanisms to generate key pairs that are independent session keys for secure data transfer.
