Office Action

§DP
DETAILED ACTION 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 . Specification The disclosure is objected to because of the following informalities: The specification should be updated to reflect the current status of all co-pending applications. Appropriate correction is required. 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 1-13 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-16 of U.S. Patent No. 12,273,248. Although the claims at issue are not identical, they are not patentably distinct from each other because claims 9-10 of the ‘248 patent anticipate claim 1 of the instant application, for example as shown below. Claim 9 of ‘248 patent Claim 1 of instant application A method for use in a network device, the method comprising: An integrated circuit for use in a network device, the integrated circuit comprising: using a receiver, receiving a signal over a link and processing the received signal; a receiver having one or more settings, wherein the receiver is configured to receive, based on the one or more settings, data traffic over a first link; and a link quality estimation circuit configured to: running an Artificial Prediction (AI) model that predicts a link quality measure indicative of a probability that the link will fail within a future time interval having a predefined length, wherein the AI model predicts the link quality measure by analyzing at least one or more settings of circuitry of the receiver; and run a pre-trained machine learning model configured to (i) analyze the one or more settings of the receiver, and (ii) predict whether a link quality of the first link is trending towards falling below a minimum requirement for the link quality; and initiating a responsive action depending on the predicted link quality measure responsive to the pre-trained machine learning model predicting that the link quality of the first link is trending towards falling below the minimum requirement, initiate a remedial measure to prevent data loss, (claim 10) wherein initiating the responsive action comprises initiating a diversion of subsequent communication, at least partially, from the link to another link. wherein the remedial measure to prevent data loss includes diverting the data traffic from the first link to a second link. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. CN 109039884 A Yadav US 12,003,282 Koul et al. US 7,720,136 Friedman et al.
