Office Action

§DP
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 . 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. 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(1)(1) - 706.02(1)(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/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.

The method of claim 16, wherein the switching further includes performing left shift operations on at least some results of the color space conversion operations. 1. A computer system comprising one or more processors and memory, wherein the computer system implements a video encoder configured to perform operations comprising: encoding video in a sequence, including: switching color spaces, color sampling rates and/or bit depths spatially and/or temporally between at least some units of the video within the sequence during the encoding, the color spaces including an RGB-type color space and a YCoCg color space; for a given unit of the units of the video, determining a prediction mode of the given unit; determining whether or not a condition is satisfied, the condition depending on one or more of the prediction mode of the given unit and whether the given unit has residual values; based at least in part on the condition being satisfied, setting a flag value for the given unit, the flag value indicating a selection between the RGB-type color space and the YCoCg color space for the given unit; entropy coding the flag value using context-adaptive binary arithmetic coding; and selectively performing deblock filtering of previously reconstructed content according to one or more rules, including adjusting strength of the deblock filtering depending on whether primary components of two adjacent blocks have non-zero residual values; and outputting encoded data in a bitstream, the encoded data including one or more signals indicating how the color spaces, the color sampling rates and/or the bit depths switch between the at least some units of the video within the sequence, wherein the one or more signals include the flag value for the given unit as part of a syntax structure for the given unit when the prediction mode of the given unit is intra or when the prediction mode of the given unit is inter and the given unit has residual values. 3. One or more non-transitory computer-readable media having stored thereon computer-executable instructions for causing one or more processors, when programmed thereby, to perform operations comprising: encoding video in a sequence, including switching color spaces, color sampling rates and/or bit depths spatially and/or temporally between at least some units of the video within the sequence during the encoding, the color spaces including an RGB-type color space and a YCoCg color space, wherein the encoding further includes: for a given unit of the units of the video, determining a prediction mode that applies for the given unit; determining whether or not a condition is satisfied, the condition depending on the prediction mode that applies for the given unit and whether the given unit has residual values; based at least in part on the condition being satisfied, setting a flag value for the given unit, the flag value indicating a selection between the RGB-type color space and the YCoCg color space for the given unit; and entropy coding the flag value using context-adaptive binary arithmetic coding; and outputting encoded data in a bitstream, the encoded data including one or more signals indicating how the color spaces, the color sampling rates and/or the bit depths switch between the at least some units of the video within the sequence, wherein the one or more signals include the flag value for the given unit as part of a syntax structure for the given unit when the prediction mode that applies for the given unit is inter and the given unit has residual values. 2. The computer system of claim 1, wherein the encoding further includes selecting between: for lossy coding, using color space conversion operations to switch between the RGB-type color space and the YCoCg color space; and for lossless coding, using invertible color space conversion operations to switch between the RGB-type color space and the YCoCg color space. 4. The one or more computer-readable media of claim 3, wherein the encoding further includes selecting between: for lossy coding, using color space conversion operations to switch between the RGB- type color space and the YCoCg color space; and for lossless coding, using invertible color space conversion operations to switch between the RGB-type color space and the YCoCg color space. 3. The computer system of claim 1, wherein the units of the video are coding units of a given picture of the sequence. 5. The one or more computer-readable media of claim 3, wherein the units of the video are coding units of a given picture of the sequence. 5. The computer system of claim 1, wherein the switching includes performing color space conversion operations between the RGB-type color space and the YCoCg color space for the given unit. 8. The one or more computer-readable media of claim 3, wherein the switching includes performing color space conversion operations between the RGB-type color space and the YCoCg color space for the given unit. 6. The computer system of claim 5, wherein the switching further includes performing right shift operations on at least some results of the color space conversion operations. 9. The one or more computer-readable media of claim 8, wherein the switching further includes performing right shift operations on at least some results of the color space conversion operations. Claims 3--22 are rejected on the ground of nonstatutory double patenting as being unpatentable over claims 1-20 of U.S. Patent No. 11,184,637 B2, 1-20 11,683,522 and claims 2-21 of PG PUB US 2025/0220227. Although the claims at issue are not identical, they are not patentably distinct from each other because most of the limitations of the instant application are similarly recited in the cited patent documents. A close look at the instant application will show that claim 3, for example, calls for [one] or more non-transitory computer-readable media having stored thereon computer-executable instructions for causing one or more processors, when programmed thereby, to perform operations comprising: encoding video in a sequence, including switching color spaces, color sampling rates and/or bit depths spatially and/or temporally between at least some units of the video within the sequence during the encoding, the color spaces including an RGB-type color space and a YCoCg color space, wherein the encoding further includes: for a given unit of the units of the video, determining a prediction mode that applies for the given unit; determining whether or not a condition is satisfied, the condition depending on the prediction mode that applies for the given unit and whether the given unit has residual values; based at least in part on the condition being satisfied, setting a flag value for the given unit, the flag value indicating a selection between the RGB-type color space and the YCoCg color space for the given unit; and entropy coding the flag value using context-adaptive binary arithmetic coding ;and outputting encoded data in a bitstream, the encoded data including one or more signals indicating how the color spaces, the color sampling rates and/or the bit depths switch between the at least some units of the video within the sequence, wherein the one or more signals include the flag value for the given unit as part of a syntax structure for the given unit when the prediction mode that applies for the given unit is inter and the given unit has residual values. Representative claims 1 of cited Patent No 11,683,522 and Patent No 11,184,637 call for similar limitations. In fact, claim 1 of Patent No 11,184,637 additionally calls for selectively performing deblock filtering of previously reconstructed content according to one or more rules, including adjusting strength of the deblock filtering depending on whether primary components of two adjacent blocks have non-zero residual values. When comparing claim 3 of the instant application and claims 1 of cited Patent No 11,683,522 and Patent No 11,184,637, it is clear that each and every limitation of claims 3, 12 and 20 of the instant application are included in claims 1-20 of the cited patents. As evidence shows, the differences between the claims of the instant application and the claims of cited Patent No 11,683,522 and Patent No 11,184,637 do not rise to the patentability level. Dependent claims 4-9, 13-19, and 21-22 are rejected by dependency from claim 3, 12 and 20.
