Office Action

§DP
DETAILED ACTION 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 §§ 706.02(l)(1) - 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. The 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/process/file/efs/guidance/eTD-info-I.jsp. Claims 1–20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1–16 of U.S. Patent No. 12,177,494. Although the claims at issue are not identical, they are not patentably distinct from each other because they are nearly identical but for some minor semantic differences, like repeating clauses from earlier in the claim or changing the ordering of the description of the claimed elements, but not in a technologically distinct way. Claims 1–20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1–16 of U.S. Patent No. 11,575,945. Although the claims at issue are not identical, they are not patentably distinct from each other because they are nearly identical but for some minor semantic differences, like repeating clauses from earlier in the claim or changing the ordering of the description of the claimed elements, but not in a technologically distinct way. Claims 1–20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1–7 of U.S. Patent No. 11,134,277. Although the claims at issue are not identical, they are not patentably distinct from each other because they are nearly identical but for some minor semantic differences, like repeating clauses from earlier in the claim or changing the ordering of the description of the claimed elements, but not in a technologically distinct way. Claims 1–20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1–7 of U.S. Patent No. 10,623,780. Although the claims at issue are not identical, they are not patentably distinct from each other because they are nearly identical but for some minor semantic differences, like repeating clauses from earlier in the claim or changing the ordering of the description of the claimed elements, but not in a technologically distinct way. Claims 1–20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1–13 of U.S. Patent No. 9,955,188. Although the claims at issue are not identical, they are not patentably distinct from each other because they are nearly identical but for some minor semantic differences, like repeating clauses from earlier in the claim or changing the ordering of the description of the claimed elements, but not in a technologically distinct way. Claims 1–20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1–16 of U.S. Patent No. 9,641,841. Although the claims at issue are not identical, they are not patentably distinct from each other because they are nearly identical but for some minor semantic differences, like repeating clauses from earlier in the claim or changing the ordering of the description of the claimed elements, but not in a technologically distinct way. Allowable Subject Matter The following is an examiner’s statement of reasons for allowance: Examiner adopts as his reasons for allowance the explanation in the submission filed by Applicant on 04/20/2016 in application no. 14/001,627. Specifically, Applicant’s argument, that the claims cover a separate treatment of the pixels on each side of the block boundary, so that the decision to filter a determined number of pixels on one side of a block boundary has no mathematical basis in (no relationship with) the pixels on the other side of the block boundary, was persuasive. Bjontegaard describes filtering equations that consider pixel values on both sides of a block boundary, so that the decision regarding how many pixels to filter is tied to the values of pixels on both sides (i.e., no separation in pixel analysis). Applicant’s arguments regarding the prior art’s separate embodiments was not persuasive to Examiner. Examiner finds the combination and/or substitutions among/between embodiments disclosed in Bjontegaard would have been obvious in view of the skill in the art. 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 Any inquiry concerning this communication or earlier communications from the examiner should be directed to Michael J Hess whose telephone number is (571)270-7933. The examiner can normally be reached Mon - Fri 9:00am-5:30pm. If attempts to reach the examiner by telephone are unsuccessful, the examiner’s supervisor, William Vaughn can be reached on (571)272-3922.
