Office Action

§DP
Notice of Pre-AIA or AIA Status The present application is being examined under the pre-AIA first to invent provisions. DETAILED ACTION This office action is in response to an amendment filed with an RCE on 07/27/2026. Claim Objections Claims 6-8 are objected to because they should each read “The non-transitory computer readable storage medium of claim 5” instead of “The bitstream of claim 5”. 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 obviousness-type 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); and 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 a nonstatutory double patenting ground provided the conflicting application or patent either is shown to be commonly owned with this application, or claims an invention made as a result of activities undertaken within the scope of a joint research agreement. Effective January 1, 1994, a registered attorney or agent of record may sign a terminal disclaimer. A terminal disclaimer signed by the assignee must fully comply with 37 CFR 3.73(b). Claims 1-12 are rejected on the ground of nonstatutory double patenting over claims 1-3 of U.S. Patent No. 9,088,796. The subject matter claimed in the instant application is fully disclosed in the patent and is covered by the patent since the patent and the application are claiming common subject matter, as follows: Although the conflicting claims are not identical, they are not patentably distinct from each other because claims 1-3 of U.S. Patent No. 9,088,796, either singularly or in combination, contain each and every element and/or render each and every element of claims 1-12 of the instant application obvious. The claims of the instant application therefore are not patently distinct from the issued patent claims and as such are unpatentable over obvious-type double patenting. Claims 1-12 are rejected on the ground of nonstatutory double patenting over claims 1-3 of U.S. Patent No. 9,516,343. The subject matter claimed in the instant application is fully disclosed in the patent and is covered by the patent since the patent and the application are claiming common subject matter, as follows: Although the conflicting claims are not identical, they are not patentably distinct from each other because claims 1-3 of U.S. Patent No. 9,516,343, either singularly or in combination, contain each and every element and/or render each and every element of claims 1-12 of the instant application obvious. The claims of the instant application therefore are not patently distinct from the issued patent claims and as such are unpatentable over obvious-type double patenting. Claims 1-12 are rejected on the ground of nonstatutory double patenting over claims 1-15 of U.S. Patent No. 9,774,863. The subject matter claimed in the instant application is fully disclosed in the patent and is covered by the patent since the patent and the application are claiming common subject matter, as follows: Although the conflicting claims are not identical, they are not patentably distinct from each other because claims 1-15 of U.S. Patent No. 9,774,863, either singularly or in combination, contain each and every element and/or render each and every element of claims 1-12 of the instant application obvious. The claims of the instant application therefore are not patently distinct from the issued patent claims and as such are unpatentable over obvious-type double patenting. Claims 1-12 are rejected on the ground of nonstatutory double patenting over claims 1-3 of U.S. Patent No. 9,930,337. The subject matter claimed in the instant application is fully disclosed in the patent and is covered by the patent since the patent and the application are claiming common subject matter, as follows: Although the conflicting claims are not identical, they are not patentably distinct from each other because claims 1-3 of U.S. Patent No. 9,930,337, either singularly or in combination, contain each and every element and/or render each and every element of claims 1-12 of the instant application obvious. The claims of the instant application therefore are not patently distinct from the issued patent claims and as such are unpatentable over obvious-type double patenting. Claims 1-12 are rejected on the ground of nonstatutory double patenting over claims 1-3 of U.S. Patent No. 10,136,137. The subject matter claimed in the instant application is fully disclosed in the patent and is covered by the patent since the patent and the application are claiming common subject matter, as follows: Although the conflicting claims are not identical, they are not patentably distinct from each other because claims 1-3 of U.S. Patent No. 10,136,137, either singularly or in combination, contain each and every element and/or render each and every element of claims 1-12 of the instant application obvious. The claims of the instant application therefore are not patently distinct from the issued patent claims and as such are unpatentable over obvious-type double patenting. Claims 1-12 are rejected on the ground of nonstatutory double patenting over claims 1-3 of U.S. Patent No. 11,006,115. The subject matter claimed in the instant application is fully disclosed in the patent and is covered by the patent since the patent and the application are claiming common subject matter, as follows: Although the conflicting claims are not identical, they are not patentably distinct from each other because claims 1-3 of U.S. Patent No. 11,006,115, either singularly or in combination, contain each and every element and/or render each and every element of claims 1-12 of the instant application obvious. The claims of the instant application therefore are not patently distinct from the issued patent claims and as such are unpatentable over obvious-type double patenting. Claims 1-12 are rejected on the ground of nonstatutory double patenting over claims 1-9 of U.S. Patent No. 11,445,197. The subject matter claimed in the instant application is fully disclosed in the patent and is covered by the patent since the patent and the application are claiming common subject matter, as follows: Although the conflicting claims are not identical, they are not patentably distinct from each other because claims 1-9 of U.S. Patent No. 11,445,197, either singularly or in combination, contain each and every element and/or render each and every element of claims 1-12 of the instant application obvious. The claims of the instant application therefore are not patently distinct from the issued patent claims and as such are unpatentable over obvious-type double patenting. Claims 1-12 are rejected on the ground of nonstatutory double patenting over claims 1-6 of U.S. Patent No. 12,081,762. The subject matter claimed in the instant application is fully disclosed in the patent and is covered by the patent since the patent and the application are claiming common subject matter, as follows: Although the conflicting claims are not identical, they are not patentably distinct from each other because claims 1-6 of U.S. Patent No. 12,081,762, either singularly or in combination, contain each and every element and/or render each and every element of claims 1-12 of the instant application obvious. The claims of the instant application therefore are not patently distinct from the issued patent claims and as such are unpatentable over obvious-type double patenting. Allowable Subject Matter The closest prior art of record, considered individually or in combination, fails to teach or reasonably suggest all the claimed features of claims 1, 5, and 9, structurally and functionally interconnected with other limitations in the manner as cited in the claims and dependent claims. The independent claims are particularly interpreted based on FIG. 8 of applicant’s drawings and [0030] of applicant’s specification. Response to Arguments Applicant's arguments filed 07/27/2026 been fully considered. However, because the above double patenting rejections have not yet been addressed, Examiner is maintaining the aforementioned double patenting rejections.
