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 .
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claim(s) 1-20 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Chen et al. (US 2023/0034458).
Regarding claim 1, Chen discloses a method of video processing (see 400 in fig. 4), comprising: obtaining, for a conversion between a video unit of a video and a bitstream of the video (see 420 and 430 in fig. 4), a prediction of at least one hypothesis of the video unit (e.g. see ¶ [0030]) by using an intra block copy (IBC) (see S1720 in fig. 17), wherein the video unit is predicated by a plurality of hypotheses (e.g. see ¶ [0165]); and performing the conversion based on the prediction of the at least one object of the video unit (see 420 and 430 in fig. 4).
Regarding claim 2, Chen further discloses wherein obtaining the prediction comprises: in accordance with a determination that the video unit is geometrically divided into a plurality of sub-partitions (see 1524 in fig. 15C), obtaining the prediction of at least one sub-partition in the video unit by using the IBC (see 1526 in fig. 15C).
Regarding claim 3, Chen further discloses wherein when the IBC is used to obtain the prediction, at least one of:
Regarding claim 4, Chen further discloses or wherein an intra prediction mode (IPM) candidate list is used and one or more IPMs of the IPM candidate list are used to obtain the prediction of the at least one sub-partition of the video unit (see fig. 1B),
Regarding claim 5, Chen further discloses wherein the IPM candidate list includes one or more IPMs from a primary most probable mode (MPM) list (see fig. 1B; e.g. see ¶ [0017])
Regarding claim 6, Chen further discloses wherein an approach of obtaining a prediction of a first component of the video unit is a same approach as an approach of obtaining a prediction of a second component (see 1522 in fig. 15C).
Regarding claim 7, Chen further discloses or wherein the prediction of the first component is obtained using a specific prediction method except IBC-GPM (see intra prediction in fig. 15C).
Regarding claim 8, Chen further discloses wherein a prediction of an area along a geometric partitioning edge of the video unit is obtained by combining predictions of two sub-partitions of the video unit (see 1526 and 1528 in fig. 15C).
Regarding claim 9, Chen further discloses wherein weights for combining the predictions are derived on-the-fly or pre-defined (e.g. see ¶ [0145]), or
Regarding claim 10, Chen further discloses wherein coding information of the video unit coded with IBC-GPM is stored and used by at least one of: one or more following video units in a current picture, or one or more video units in one or more following pictures (e.g. see ¶ [0145], [0181]).
Regarding claim 11, Chen further discloses wherein the coding information refers to at least one: block vector (BV), intra prediction mode, or motion vector (e.g. see ¶ [0168], [0181]),
Regarding claim 12, Chen further discloses or wherein one or more BVs in a first sub-partition are used (see BVIBC in fig. 15C),
Regarding claim 13, Chen further discloses wherein a determination of whether the video unit is allowed to be coded with IBC-GPM mode depends on coded information (e.g. see ¶ [0160]-[0161]), or
Regarding claim 14, Chen further discloses wherein whether to and/or how to apply IBC-GPM to the video unit are indicated in the bitstream (e.g. see ¶ [0160]-[0161]).
Regarding claim 15, Chen further discloses wherein whether to enable IBC-GPM to the video unit is indicated using one or more syntax elements (e.g. see ¶ [0160]-[0161]), or
Regarding claim 16, Chen further discloses wherein a syntax element is used to indicate whether IBC-GPM is applied to the video unit (e.g. see ¶ [0160]-[0161]), or
Regarding claim 17, Chen further discloses wherein the conversion includes encoding the video unit into the bitstream, or wherein the conversion includes decoding the video unit from the bitstream (see 420 and 430 in fig. 4).
Regarding claim 18, the claim(s) recite an apparatus (see 400 in fig. 4) with analogous limitations to claim 1, and is/are therefore rejected on the same premise.
Regarding claim 19, the claim(s) recite analogous limitations to claim 1, and is/are therefore rejected on the same premise.
Regarding claim 20, the claim(s) recite analogous limitations (e.g. see ¶ [0034]) to claim 1, and is/are therefore rejected on the same premise.
Response to Arguments
Applicant's arguments filed 5/26/26 have been fully considered but are moot in view of the new ground(s) of rejection.
Citation of Pertinent Art
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
1. Chiu et al. (US 2021/0227206), discloses coding/decoding geometric partition and intra block copy.
2. Chen et al. (US 2023/0073917), discloses coding/decoding geometric partition and intra block copy.
3. Chen et al. (US 2023/0079960), discloses coding/decoding geometric partition and intra block copy.
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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.
