Office Action

§DP
CTNF 18/975,721 CTNF 83771 DETAILED ACTION Notice of Pre-AIA or AIA Status 07-03-aia AIA 15-10-aia The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA. Claims 1-24, filed on 12/10/2024 are presented examination. Double Patenting 08-33 AIA The non-statutory 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 non-statutory 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 non-statutory 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 non-statutory 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. Independent Claims 1, 7, 13 and 19 are rejected on the ground of non-statutory double patenting as being unpatentable over independent claims 1, 9, 17 and 33 of U.S. Patent No. 12199962 B2. Although the claims at issue are not identical, they are not patentably distinct from each other because the claim features of the instant application are broader versions of the patent; which is the parent case.

Allowable Subject Matter Claims 1, 7, 13 & 19 would be allowable if the above non-statutory double patenting rejection is overcome (i.e., by filing terminal disclaimer/s). 13-03 AIA The following is an examiner’s statement of reasons for allowance: Regarding Independent Claims 1, 7, 13 and 19 , With examiner’s thorough search the closest prior arts found are Faibish et al. (US 8719590 B1) directed to Cloud infrastructure of an information processing system comprises one or more processing devices implementing a plurality of virtual machines. The cloud infrastructure is configured to receive a processing job from a tenant, to obtain a first key specific to the tenant, to determine a second key utilizing information supplied by the tenant, and to encrypt one or more results of the processing job utilizing a combination of the first key and the second key. At least a portion of the second key is determined by at least one application that is run on at least one virtual machine of the cloud infrastructure in conjunction with performance of the processing job. The encrypted results of the processing job may be stored in a virtual memory of the cloud infrastructure and transmitted to the tenant; and, Ferguson et al. (2015/0319160 A1) is directed to Deploying an encrypted entity on a trusted entity is illustrated herein. A method includes, at a trusted entity, wherein the trusted entity is trusted by an authority as a result of providing a verifiable indication of certain characteristics of the trusted entity meeting certain requirements, receiving an encrypted entity from an untrusted entity. The untrusted entity is not trusted by the authority. At the trusted entity, a trust credential from the authority is used to obtain a key from a key distribution service. The key distribution service is trusted by the authority. The key is used to decrypt the encrypted entity to allow the encrypted entity to be deployed at the trusted entity. However, neither Faibish et al. nor Ferguson et al., alone or in combination teach or suggest the claimed subject matter as disclosed in the independent claims. And, the features in the claim features of the instant application are broader versions of the patented claims in the parent application. Claims 2-6, 8-12, 14-18 & 20-24 are indicated as allowable because of their dependence . Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.” Conclusion 07-96 AIA The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. (S ee PTO—892). F or example, US 2015/0379282 A1 is directed to Encryption System In A Virtual Environment.
