Office Action

§DP
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 . Detailed Action Response to Amendment This Office Action is in response to the correspondence on 12/23/2025. Applicant’s argument, filed on 12/23/2025 has been entered and carefully considered. Claims 1-6 are pending. Response to Arguments Applicant’s arguments in the 12/23/2025 Remarks have been fully considered but they are not persuasive because of the following: Regarding claims, on page 6-11 argues “second quad-division”. While the applicant’s argument points are understood, the examiner respectfully disagrees (The claim limitation recites, “…. a second quad-division …”, so, any one options would satisfy the scope of the current claim, the rejection is maintained). Therefore, the rejection is maintained. 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, 4-6 and similar dependent claims are rejected on the ground of nonstatutory double patenting as being unpatentable over claim 1 of Conflicting Patent PAT US 11,902,579 B2. Although the claims at issue are not identical, they are not patentably distinct from each other because the subject matter claimed in the instant application is anticipated by the Conflicting Patent and is covered by the Patent since the Patent and the application are claiming common subject matter, below is a list of limitations that perform the same function, however, different terminology may be used in both sets to describe the limitations, as follows, Claim 1 is used as an example to analyze the common subject matter: Conflicting Patent No. US 11,902,579 B2 Instant Application:-18/809,722 1. A method of decoding an image with a decoding apparatus, comprising: receiving a bitstream in which the image is encoded; obtaining, from the bitstream, a single index for specifying a block division type of a current block in the image; determining, based on the single index, the block division type of the current block from a candidate group pre-defined in the decoding apparatus, wherein the single index is used to select one candidate division types among a plurality of candidate division types included in the candidate group, wherein the plurality of candidate division types include a non-division, a first quad-division, a second quad-division, a binary-division and a triple-division, wherein the first quad-division is representative of dividing, based one horizontal line and one vertical line, one coding block into four coding blocks, the second quad-division is representative of dividing, based on three horizontal lines or three vertical lines, one coding block into four coding blocks, the binary-division is representative of dividing one coding block into two coding blocks, and the triple-division is representative of dividing one coding block into three coding blocks, wherein the binary-division includes a horizontal binary-division and a vertical binary-division, and wherein the bitstream includes a first flag specifying whether to perform the horizontal binary-division and a second flag specifying whether to perform the vertical binary-division, the first flag being different from the second flag; dividing, based on the determined block division type, the current block into a plurality of sub-blocks; and decoding each of the sub-blocks with reference to syntax information obtained from the bitstream, wherein two coding blocks among the three coding blocks obtained by the triple-division have the same size each other and the remaining coding block among the three coding blocks has a size different from the size of the two coding blocks. 1. An image decoding method performed by an image decoding apparatus, the image decoding method comprising: receiving a bitstream in which an image is encoded; obtaining index information for specifying a block division type of a current block in the image from the bitstream; determining the block division type of the current block from a candidate group pre-defined in the image decoding apparatus based on the index information; dividing the current block into a plurality of sub-blocks based on the determined block division type; and decoding each of the sub-blocks to reconstruct the current block, wherein the current block is reconstructed based on prediction for the current block, wherein, when a size of the current block is within a predetermined range, the candidate group includes at least one of a non-division, a first quad-division, a second quad-division, a binary-division or a triple-division, wherein, when the size of the current block is out of the predetermined range, the plurality of candidate division types does not include at least one among the second quad-division or the triple-division, and wherein the first quad-division divides one coding block into four coding blocks based one horizontal line and one vertical line, the second quad-division divides one coding block into four coding blocks based on three horizontal lines or three vertical lines, the binary-division divides one coding block into two coding blocks, and the triple-division divides one coding block into three coding blocks. As demonstrated, the claim of US patent US 11,902,579 B2 anticipate the features of the claim of instant application 18/809,722. Similar rejections can be presented against patents, US 11,910,018 B2, US 11,902,668 B2, US 11,882,281 B2, US 11,539, 979 B2, and US 11,483,476 B2. A nonstatutory type (35 U.S.C. 101) double patenting rejection can be overcome by amending the conflicting claims so they are no longer coextensive in scope or filing of a terminal disclaimer. Conclusion THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a). A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
