Office Action

§DP
DETAILED ACTION Claims 2-17 are pending for examination. 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 . Priority Acknowledgment is made of applicant's claim under GB 1812708 filed on 8/3/2018. Response to Arguments The previous rejection made in the non-final office action dated 1/28/2026 has been withdrawn since it did not reject the preliminary amendments filed 6/20/2025. A new non-final rejection is written with respect to the previous presented claims written in the Applicant’s arguments filed 5/28/2026. Double Patenting 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 time-wise 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, 140F.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 USPQ645 (Fed. Cir. 1985); In re Van Ornum, 686 F.2d 937, 214 USPQ761 (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 §§ 706.02(l)(l) - 706.02(l)(3) 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 USPTO Internet website contains terminal disclaimer forms which may be used. Please visit www.uspto.gov/patent/patents-forms.Thefiling date of the application in which the form is filed determines what form (e.g., PTO/SB/25, PTO/SB/26, PTO/AI A/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/process/file/efs/guidance/eTD-info-l.jsp. Claims 2-17 are rejected on the ground of non-statutory double patenting as being unpatentable over claims 21-33 and 35-38 of U.S. Patent No. 12,212,781. The claims at issue are not identical because the present invention claims the decoder embodiments that perform similar functions but in reverse with respect to the input/bitstream/output claimed to the encoder embodiments claimed in the US Patent. However, they are not patentably distinct from each other because they both claim limitations relating to producing a base signal to select between kernels of different configurations, to produce residual signals, to produce where residual signal have mass ranges within a threshold around 0, such that level 0 and level 1 enhancement streams have their masses at about a value of 0. Allowable Subject Matter Claims 2-17 are objected to as having a double patent rejection on said claims. The Double Patent rejection can be overcome through sufficient amendments to the claims or a terminal disclaimer.
