Claim Rejections - 35 USC § 102 07-07-aia AIA 07-07 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 – 07-08-aia AIA (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. 07-15 AIA Claim (s) 1-6 and 12-20 are rejected under 35 U.S.C. 102( a)(1 ) as being anticipated by Soman et al. (US 20220337888 A1) . Regarding claims 1, 12, and 18 , Soman teaches: “receiving a mixed-bitrate encoded audio packet that includes encoding vectors representative of a quantized current audio frame and quantized past audio frames, wherein the encoding vectors include a current high-bitrate encoding vector having a high encoding bitrate and past low-bitrate encoding vectors having low encoding bitrates that are less than the high encoding bitrate” (par. 0081; ‘The segmenter module [208C] is configured to receive the uniform segments of content from the encoder [204B] of the content encoding server [204] encoded at different bitrates and create the streams of the audio-visual data based on the virtual manifest created by the manifest module [208B].’); “selecting a subset of the encoding vectors” (par. 0081; ‘The segmenter module [208C] of the content transmission server [208] dynamically modifies at least one of a segment length and a segment size for the one or more segments based on the determined the target segment length and the target segment size, in an event the expected efficiency is above a pre-defined threshold.’); “repacketizing the subset of the encoding vectors into a transcoded audio packet that has different encoding bitrates from the mixed-bitrate encoded audio packet” (par. 0151; ‘Further, the segmenter module [208C] may dynamically and virtually combine the uniform size segments of 2 MB encoded at different bit rates to form a stream of data to be transferred.’); and “transmitting the transcoded audio packet over a network link” (par. 0143; ‘The transceiver [208A] of the content transmission server [208] delivers the content to the at least one user device [202] based on the at least one target failsafe rendition.’). Regarding claims 2 (dep. on claim 1), 13 (dep. on claim 12), and 19 (dep. on claim 18) , Soman further teaches: “receiving includes receiving the mixed-bitrate encoded audio packet to further include a current low-bitrate encoding vector having a low encoding bitrate that is less than the high encoding bitrate” (par. 0151; ‘Further, the segmenter module [208C] may dynamically and virtually combine the uniform size segments of 2 MB encoded at different bit rates to form a stream of data to be transferred.’). Regarding claims 3 (dep. on claim 1), 14 (dep. on claim 12), and 20 (dep. on claim 18) , Soman further teaches: “the current high-bitrate encoding vector includes q codeword indices representative of the high encoding bitrate, and the past low-bitrate encoding vectors each includes less than q codeword indices representative of the low encoding bitrates” (par. 0059; ‘As used herein, a “first parameters” may comprise of the information about the user device [202] to which the audio-visual content is being transmitted, the bit rate at which the segments are being transmitted, the time taken by the playback buffer to download a single segment, the segment size in respect of all segments of the an audio-visual content delivery session, the size of the data in every segment, a network type (for example, network is a cellular network, e.g. 3G, 4G, 5G, or a Wi-Fi network), the playback buffer information of the user device [102].’ Q codeword indices are used in 4G and 5G networks.). Regarding claims 4 (dep. on claim 1) and 15 (dep. on claim 12) , Soman further teaches: “the low encoding bitrates of the past low-bitrate encoding vectors vary across the past low-bitrate encoding vectors” (par. 0151; ‘Further, the segmenter module [208C] may dynamically and virtually combine the uniform size segments of 2 MB encoded at different bit rates to form a stream of data to be transferred.’). Regarding claims 5 (dep. on claim 4) and 16 (dep. on claim 15) , Soman further teaches: “the low encoding bitrates decrease as time offsets increase between the current high-bitrate encoding vector and the past low-bitrate encoding vectors” (par. 0150; ‘That is, the same data has 4 segments of 2 MB size each with bitrates 1.5 mbps, 4 mbps, 6 mbps and 13 mbps (as shown).’). Regarding claims 6 (dep. on claim 1) and 17 (dep. on claim 12) , Soman further teaches: “determining link parameters for the network link, wherein selecting includes selecting the subset based on the link parameters” (par. 0151; ‘Thereafter, upon receipt of the one or more parameters from the at least one user device [202] by the content transmission server [208], the manifest module [208B] of the content transmission server [208] dynamically creates a virtual manifest for transfer of the audio-visual data encoded at different bitrates.’) . Allowable Subject Matter 12-151-08 AIA 07-43 12-51-08 Claim s 7-11 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. 13-03-01 AIA The following is a statement of reasons for the indication of allowable subject matter: Regarding claim 7 (dep. on claim 6) , Soman does not expressly teach packet-loss rate, as in “the link parameters indicate a bandwidth and a packet-loss rate; and selecting includes selecting the subset based on the bandwidth and the packet-loss rate.” While there are prior art, such as Jensen et al. (US 20200194029 A1), that teach speech encoder and decoder systems that provide high-quality voice and audio over insufficient bandwidth or high packet loss rates (see Jensen: par. 0058), the prior art, whether taken alone or in combination, fails to teach, inter alia, “selecting includes selecting the subset based on the bandwidth and the packet-loss rate.” Claims 8-10 are dependent upon objected claim 7. Regarding claim 11 (dep. on claim 6) , the prior art of record, taken alone or in combination, fails to teach “the link parameters indicate a packet-loss burst length; and selecting increases or decreases a number of the encoding vectors in the subset in correspondence with increases or decreases in the packet-loss burst length.” Conclusion Other pertinent prior art are cited in the PTO-892 for the applicant's consideration.
