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
Following prior arts are considered pertinent to applicant's disclosure.
US 10491902 B1 (hereinafter Xu; provisional application 62/698,559 relied upon in the analysis)
Zhang et. al. “CE4-related: History-based Motion Vector Prediction” Joint Video Experts Team (JVET) of ITU-T SG 16 WP 3 and ISO/IEC JTC 1/SC 29/WG 11 11th Meeting: Ljubljana, SI, 10-18 July 2018 (Section “2. Proposed method”, Figs.2-3)
Allowable Subject Matter
Claims 1-20 are allowable over prior art.
The following is an examiner’s statement of reasons for allowance:
The primary reason for allowance of independent claim 1 is that the “wherein the rule of updating specifies to skip updating the one or more HMVP tables due to a prediction direction being a uni-direction” limitations in the context of other limitations in the claim, considering the claim as a whole, is not anticipated nor is obvious over the prior art of record or prior art found during Examiner’s search. Other Independent Claims are allowable for similar reason. Depended claims are allowable, at least, because of their dependence on the allowable independent claim.
For instance, Xu teaches a rule of updating one or more history-based motion vector predictor (HMVP) tables with HMVP candidates is satisfied, wherein the rule of updating is based on a prediction direction used for the conversion [(“Method 1” of pages 4-5 describes based on uni-prediction or bi-prediction new MV are added to the existing one; list teaches table)]
Zhang et. al. teaches updating HMVP candidate tables and various rules to update it (Section “2. Proposed method”, Figs.2-3)
However, none of the prior art alone or in a combination teaches “wherein the rule of updating specifies to skip updating the one or more HMVP tables due to a prediction direction being a uni-direction”.
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 claims at issue 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 reference 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. A terminal disclaimer must be signed in compliance with 37 CFR 1.321(b).

Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-19 of U.S. Patent No. 12132889. Although the claims at issue are not identical, they are not patentably distinct from each other. For instance, instant independent claim 1 taught by patented claim combinations of 1 & 2. Similarly instant claims 19 and 20 are obvious over patented claims 18 & 2 and 19 & 2 respectively (see the table below). Instant dependent claims are obvious variation of or combinations of patented claims

Claims 1-20 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 11616945. Although the claims at issue are not identical, they are not patentably distinct from each other. For instance, instant independent claims (i.e. claims 1, 19 & 20) are obvious variation of patented claims 1, 17 & 18 (see the table below). Instant dependent claims are obvious variation of or combinations of patented claims
