FRAHM, JOHNNY A. KUMAR, and NORMAN H. BEAMER, Administrative Patent Judges. KUMAR, Administrative Patent Judge. DECISION ON REQUEST FOR REHEARING Appeal 2017-006450 Application 13/599,360 Appellants filed a Request for Rehearing under 37 C.F.R. § 41.52(a)(1) (“Request”) on (Dec. 12, 2017), for reconsideration of our Decision mailed (Nov. 13, 2017) (“Decision”).1 The Decision affirmed the Examiner’s rejections of claims 1, 2, 4—11, 13—16, and 21—25. We reconsider our decision in light of Appellants’ Request for Rehearing, but we decline to change the decision. Representative Claim Independent claim 1, reproduced below, is representative of the subject matter on Request for Rehearing. 1. A method for decoding a video signal having a plurality of frames including a current frame, comprising: generating an alternate reference frame, wherein the alternate reference frame occurs prior to the current frame in the video signal and wherein the alternate reference frame is other than a frame immediately prior to the current frame; detecting, after generating the alternate reference frame, an error in the current frame and reporting the detected error; receiving a recovery frame in response to reporting the detected error; and decoding the recovery frame using the alternate reference frame. App. Br. 9-10 (Claims Appendix). We find Appellants’ arguments unpersuasive for the reasons given in our prior Decision. For the reasons given in the Final Rejection and Examiner’s Answer, we agree with the Examiner’s findings (Final Act. 2— 12; Ans. 11—12) that exemplary independent claims 1 and 10 are obvious 1 “The request for rehearing must state with particularity the points believed to have been misapprehended or overlooked by the Board.” 37 C.F.R. § 41.52(a)(1). 2 Appeal 2017-006450 Application 13/599,360 over Cosman (US 2006/0098738 Al, pub. May 11, 2006) and Wiegand {LONG-TERM MEMORY MOTION-COMPENSATED PREDICTION FOR ROBUST VIDEO TRANSMISSION, 0-7803-6297-7 (2000) IEEE. We highlight the following for emphasis. Appellants simply repeat their contentions from their Appeal and Reply Briefs and contend: 1. Both Cosman and Wiegand are directed to techniques wherein the encoder receives feedback indicating a decoding error such that that the most recent reference frame at the decoder differs from the corresponding frame at the encoder, and, in response, the encoder redecodes the most recent reference frame to match the corresponding frame at the decoder so that the re-decoded most recent reference frame can be used. Appeal 5-6. Given that both Cosman and Wiegand describe re-decoding frames at the encoder in response to feedback, and that neither Cosman nor Wiegand describes using a long-term reference frame in response to feedback, Appellant respectfully submits that “generating a recovery frame in response to the received report, and encoding the recovery frame using the alternate reference frame,” as recited by independent claim 10, is not obvious. Appeal 6. Request 4. 2. The Board also overlooked or misapprehended Appellant’s arguments that the Wiegand does not disclose “encoding the recovery frame,” as recited by independent claim 10. Appeal 6-7, Reply 2-3. In particular, the Examiner expressly admits that “Wiegand fails to disclose using the alternate reference frame to encode the feedback frame.” Final Act. 7. The Examiner’s phrasing implies that “using the alternate reference frame” is the sole operative element that Wiegand fails to disclose; however, this phrasing obfuscates the more significant deficiency of Wiegand, that Wiegand does not teach, suggest, or imply “[encoding] the recovery frame” at all. Appeal 7, Reply 3.” Request 5. 3. To the extent that Examiner is arguing that any operation of the encoder with respect to a feedback frame qualifies as encoding the 3 Appeal 2017-006450 Application 13/599,360 feedback frame, Appellant respectfully submits that “[one] skilled in the art would not consider the operations of the encoder with respect to the "feedback frame" described by Wiegand as being equivalent to "encoding the recovery frame" as recited by independent claim 10.” Final Act. 2. For example, one skilled in the art would not considering receiving a NACK to be equivalent to encoding a feedback frame. Furthermore, one skilled in the art would not consider “error concealment in the feedback frame” as being equivalent to encoding the feedback frame. “When a portion of [a] received frame is corrupted, the decoder’s post-processing methods seek to conceal this from the viewer [using error concealment], (Cosman A [0033]).” Appeal 5. “Thus, “[the encoder uses] the feedback information to decode a past frame so that it is identical to the decoder’s version of that frame.” (Cosman A [0076], see also Wiegand § 4.2, NACK mode).” Appeal 5. Request 6. 4. The Board also either overlooked or misapprehended Appellant’s arguments showing that combining Cosman and Wiegand as suggested by the Examiner would not have produced the asserted benefit of increasing the robustness of a video codec. In particular, Appellant argued that both Cosman and Wiegand describe substantially similar subject matter. For example, “both Cosman and Wiegand describe feedback based techniques for addressing error propagation when multiple reference frames and error concealment are used.” Appeal 5. Wiegand is cited narrowly for the content of section 4.2, which the Examiner concludes “discloses robust video transmission wherein a feedback frame, i.e. a recovery frame, is generated in response to a received error report from the decoder.” However, Cosman describes “the use of feedback from the decoder[, wherein] the encoder knows which GOBs were received intact and which ones were dropped, [and] can simulate the decoder's operation exactly, including error concealment.” Cosman, [0076]; Appeal 5. Request 7—8. Appellants’ contentions are restatements of the arguments presented in Appellants’ briefing as to alleged errors in the Examiner’s fact finding. 4 Appeal 2017-006450 Application 13/599,360 Appellants’ arguments were addressed in our decision (Decision 4—6) and will not be repeated here. We find that Appellants’ restatements of arguments are addressed to the Examiner’s application of the references rather than to points believed to have been misapprehended or overlooked by the Board. Based on the Examiner’s claim construction, we agreed with findings and conclusions made by the Examiner (see Final Act. 2—11; Ans. 6—7). Appellants have failed to show any matter that was misapprehended or overlooked by the Board in rendering this Decision. We decline to change our prior Decision. CONCLUSION In view of the foregoing discussion, we grant Appellants’ Request for Rehearing to the extent of reconsidering our decision, but we deny Appellants’ request with respect to making any change thereto. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(l)(iv). REHEARING DENIED 5 Copy with citationCopy as parenthetical citation
