Claim Rejections - 35 USC § 112
The following is a quotation of the first paragraph of 35 U.S.C. 112(a):
(a) IN GENERAL.—The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
The following is a quotation of the first paragraph of pre-AIA 35 U.S.C. 112:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
Claims 1-24 are rejected under 35 U.S.C. 112(a) or 35 U.S.C. 112 (pre-AIA ), first paragraph, as failing to comply with the written description requirement. The claim(s) contains subject matter which was not described in the specification in such a way as to reasonably convey to one skilled in the relevant art that the inventor or a joint inventor, or for applications subject to pre-AIA 35 U.S.C. 112, the inventor(s), at the time the application was filed, had possession of the claimed invention.
The claims include the limitation “pre-set” output delta. The examiner notes this claim language was previously added to application (17/527,894, Amendment 10/21/24) however no comments regarding support of such amendment were included, nor could the examiner locate support in the original disclosure for such amendment. If the applicant’s position is that Pre-set is inherent, although not explicitly recited, clarification from applicant is required.
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 § 2146 et seq. 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 filing of a terminal disclaimer by itself is not a complete reply to a nonstatutory double patenting (NSDP) rejection. A complete reply requires that the terminal disclaimer be accompanied by a reply requesting reconsideration of the prior Office action. Even where the NSDP rejection is provisional the reply must be complete. See MPEP § 804, subsection I.B.1. For a reply to a non-final Office action, see 37 CFR 1.111(a). For a reply to final Office action, see 37 CFR 1.113(c). A request for reconsideration while not provided for in 37 CFR 1.113(c) may be filed after final for consideration. See MPEP §§ 706.07(e) and 714.13.

Although the claims at issue are not identical, they are not patentably distinct from each other because the claims are obvious variants of each other.
Examiner notes that the instant claims compared to the copending claims lack the features of based on the error, determining, based on a pre-set output delta and the audio frame output time, a corrected video frame output time and adjusting the video frame output time to the corrected video frame output time
However, You (Pub 20210368223) discloses based on the error, determining, based on a pre-set output delta and the audio frame output time, a corrected video frame output time, (Para. [0048] note recorded timestamp, construed as pre-set output delta, is used to determine target audio/video timestamps) and adjusting the video frame output time to the corrected video frame output time, (In Step 303, an adjusting module adjusts timestamps of either audio or video when an abnormality is detected in previous Step 302). It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify the claims for the benefit of allowing accurate audio-video synchronization. See table below.

Claim Rejections - 35 USC § 102
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)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 1-3, 5-9, 11-15, 17-21, 23, and 24 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by You (Pub 20210368223).
Regarding claims 1, 7, 13, and 19, You discloses:
determining, by a computing device, a video frame output time associated with a video
frame and an audio frame output time associated with an audio frame, (note Step 301 “determination module” Fig 3 and Para. [0052]. The determination module extracts audio and video frames and respective timestamps);
determining, based on the video frame output time and the audio frame output time,
an error associated with the video frame output time, (in Fig 3 Step 302, a decision module determines whether abnormality exists by comparing audio/video timestamps acquired in previous Step 301);
based on the error, determining, based on a pre-set output delta and the audio frame output time, a corrected video frame output time, (Para. [0048] note recorded timestamp, construed as pre-set output delta, is used to determine target audio/video timestamps)
and adjusting the video frame output time to the corrected video frame output time, (In Step 303, an adjusting module adjusts timestamps of either audio or video when an abnormality is detected in previous Step 302).
Regarding claims 2, 8, 14, and 20, You discloses wherein determining the corrected video frame output time comprises subtracting the pre-set output delta from the audio frame output time, (Para. [0048], note subtracting a recorded timestamp, construed as a preset output delta from audio/video timestamps to generate target audio/video timestamps).
Regarding claims 3, 9, 15, and 21, You discloses further comprising causing output of the video frame at the corrected video frame output time, (Para. [0049] note adjusting target audio/video timestamps).
Regarding claims 5, 11, 17, and 23, You discloses further comprising receiving the video
frame comprising video frame metadata, wherein the video frame output time and the audio frame output time are determined based on the video frame metadata, (note push-stream edge node may retrieve timestamp corresponding to audio/video frame preceding a target audio/video frame, Para. [0040]).
Regarding claims 6, 12, 18, and 24, You discloses wherein determining the error
associated with the video frame output time comprises: determining, based on the video frame output time and the audio frame output time, a calculated output delta; and determining, based on a difference between the pre-set output delta and the calculated output delta satisfying a threshold, the error associated with the video frame output time, (note when a gap between target and preceding audio/video timestamps, an abnormality is determined. The timestamps may be adjusted when they exceed a preset time difference threshold Para. [0039][0043]).
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
The factual inquiries for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows:
1. Determining the scope and contents of the prior art.
2. Ascertaining the differences between the prior art and the claims at issue.
3. Resolving the level of ordinary skill in the pertinent art.
4. Considering objective evidence present in the application indicating obviousness or nonobviousness.
Claim(s) 4, 10, 16, and 22 are rejected under 35 U.S.C. 103 as being unpatentable over You in view of Matsuo (Pub 20150215496).
Regarding claims 4, 10, 16, and 22, You discloses claims 1, 7, 13, 19. However,
determining, based on a video frame decode time and the corrected video frame output time, a corrected video frame decode time; and adjusting the video frame decode time to the corrected video frame decode time is not disclosed.
In a similar field of endeavor, Matsuo discloses determining, based on a video frame decode time and the corrected video frame output time, a corrected video frame decode time; and adjusting the video frame decode time to the corrected video frame decode time, (Para. [0104] changing decoding time based on frame output time, PTS, and decoding time DTS). It is known in the art to synchronize audio and video streams based on decoding and presentation timing so that the user’s enjoyment is improved. It would have been obvious to one of ordinary skill in the art before the effective filing date of the invention to modify You by Matsuo to achieve noted benefit.
