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).

Although the conflicting claims are not identical, they are not patentably distinct from each other, because claims 1, 8-11 of the instant application differs from claims 1-5 of US Pat 12,047,583 B2 in that the instant application recites a broader claim scope while the claims in US Pat 12,047,583 B2 recites additional features that encompasses the claim scope of the corresponding claims of instance application.
Claims 2-5, 7, 13-16, 22-25, and 27-30 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-5 of U.S. Patent No. 12,047,583 B2 in view of Xu (US 20200186823 A1).
Regarding claim 2, the corresponding claims of US Pat 12,047,583 B2 discloses the limitation

But it does not disclose determining whether the second syntax element identifying the motion vector difference is included in the bitstream of encoded video data based on the value of the first syntax element comprises determining that the second syntax element is not included in the bitstream of encoded video data in response to value of the first syntax element not being equal to K, wherein K is an integer value corresponding to an index of a second candidate in the first list of candidate motion vectors, wherein the second candidate is different than the candidate.
However, Xu teaches determining whether the second syntax element identifying the motion vector difference is included in the bitstream of encoded video data based on the value of the first syntax element comprises determining that the second syntax element is not included in the bitstream of encoded video data in response to value of the first syntax element not being equal to K, wherein K is an integer value corresponding to an index of a second candidate in the first list of candidate motion vectors, wherein the second candidate is different than the candidate (Xu; Para.

A second syntax element is determined being not included in the bitstream in accordance with a first syntax element when a first syntax element is not equal to any integer K less than a threshold, wherein K corresponds to an index of a second candidate in a first list of motion vectors, being different from the candidate.).
Therefore, it would have been obvious to a person with ordinary skill in the pertinent before the effective filing date of the claimed invention to further modify the video coding system of corresponding claims of US Pat 12,047,583 B2 to adapt a motion vector syntax element signaling scheme, by incorporating Xu’s teaching wherein motion vectors in the bi-directions are signaled and derived, for the motivation to obtain motion vectors based on MVD and MVP (Xu; Abstract.).
Regarding claim 3, the modification further teaches determining the first motion vector for the current block based on the motion vector predictor and the motion vector difference comprises setting a value of the motion vector difference equal to zero in response to determining that the second syntax element is not included in the bitstream of encoded video data (Xu; Para. [0151], Fig. 8. For a MVD being not included in a bitstream, a motion vector is determined without using the MVD, i.e. being set to zero.).
Regarding claim 4, , the modification further teaches determining whether the second syntax element identifying the motion vector difference is included in the bitstream of encoded video data based on the value of the first syntax element comprises determining that the second syntax element is included in the bitstream of encoded video data in response to value of the first syntax element being equal to K, wherein K is an integer value corresponding to an index for the candidate in the first list of candidate motion vectors (Xu; Para. [0151], Fig. 8. A second syntax element is determined being included in the bitstream in accordance with a first syntax element when a first syntax element is not equal to any integer K greater than a threshold, wherein K corresponds to an index of a second candidate in a first list of motion vectors.).
Regarding claim 5, the modification further teaches receiving an instance of the second syntax element in the bitstream of encoded video data in response to determining that the second syntax element is included in the bitstream of encoded video data (Xu; Para. [0151], Fig. 8. An instance of a second syntax element is received for a second syntax being included in the bitstream.).
Regarding claim 7, the modification further teaches determining whether the second syntax element identifying the motion vector difference is included in the bitstream of encoded video data based on the value of the first syntax element comprises determining that the second syntax element is included in the bitstream of encoded video data in response to value of the first syntax element being equal to k, wherein k is integer value corresponding to an index for the candidate in the first list of candidate motion vectors (Xu; Para. [0151], Fig. 8. A second syntax element is determined being included in the bitstream in accordance with a first syntax element when a first syntax element is not equal to any integer K greater than a threshold, wherein K corresponds to an index of a second candidate in a first list of motion vectors.).
Claims 6, 17, and 31 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-5 of U.S. Patent No. 12,047,583 B2 in view of Xu (US 20200186823 A1), and further in view of Liu’2 (WO 2020221258 A1).
Regarding claim 6, the modification determining whether the second syntax element identifying the motion vector difference is included in the bitstream of encoded video data based on the value of the first syntax element (See the table regarding claim 1 above.).
But it does not specifically teach determining whether the second syntax element identifying the motion vector difference is included in the bitstream of encoded video data based on the value of the first syntax element comprises: determining a reference picture index associated with the first motion vector; and determining whether the second syntax element identifying the motion vector difference is included in the bitstream of encoded video data based on the reference picture index.
However, Liu’2 teaches determining whether the second syntax element identifying the motion vector difference is included in the bitstream of encoded video data based on the value of the first syntax element comprises: determining a reference picture index associated with the first motion vector; and determining whether the second syntax element identifying the motion vector difference is included in the bitstream of encoded video data based on the reference picture index (Liu’2; Para. [0077-78]. A second syntax element indicating the MVD is determined to be included in a bitstream in accordance with a reference picture index.).
Therefore, it would have been obvious to a person with ordinary skill in the pertinent before the effective filing date of the claimed invention to further modify the video coding system of corresponding claims of US Pat 12,047,583 B2 to adapt a MVD mode scheme, by incorporating Liu’2’s teaching wherein MVD is enabled according to reference picture indexes, for the motivation to MVD coding (Liu’s; Abstract.).
Claims 17 is directed to a device for decoding a bitstream of encoded video data, the device comprising: a memory; and one or more processors implemented in circuitry and configured to perform a sequence of processing steps corresponding to the same as claimed in claim 6 , and is non-patentable over the prior art for the same reason as previously indicated.
Claim 31 is directed to a device for encoding video data, the device comprising: a memory configured to store the video data; and one or more processors implemented in circuitry and configured to perform a sequence of processing steps that are in reverse/reciprocal manner with the steps corresponding to the same as claimed in claim 6, and is non-patentable over the prior art for the same reason as previously indicated.
