Paper No. 29 UNITED STATES PATENT AND TRADEMARK OFFICE __________ BEFORE THE BOARD OF PATENT APPEALS AND INTERFERENCES __________ Ex parte YASUHIRO TAKISHIMA, SHIGEYUKI SAKAZAWA, and MASAHIRO WADA __________ Appeal No. 2002-0745 Application 08/893,379 ___________ ON BRIEF ___________ Before JERRY SMITH, BARRETT and LEVY, Administrative Patent Judges. JERRY SMITH, Administrative Patent Judge. DECISION ON APPEAL This is a decision on the appeal under 35 U.S.C. ' 134 from the examiner=s rejection of claims 1-7, 9, 13-19 and 21. Claims 8, 10-12, 20 and 22-24 have been allowed by the examiner. The disclosed invention pertains to a method and apparatus for second or later generation coding of a video signal in the field of tandem stage coding. The invention is disclosed Appeal No. 2002-0745 Application 08/893,379 2 as providing a solution which will enable the encoding of a video signal which considers the coding history of the video signal when the actual coding parameters are not available. Representative claim 1 is reproduced as follows: 1. A method for second or later generation coding of a video signal in tandem stage coding which includes a previous stage coding process and a later stage coding process which are separately and sequentially executed, comprising the steps of: estimating at least one coding parameter used in the previous stage coding process in accordance with picture properties of the video signal coded by said previous stage coding process; and secondly coding the video signal coded by said previous stage coding process, based upon the estimated coding parameter. The examiner relies on the following references: Trew 4,941,044 July 10, 1990 Fuchigama et al. (Fuchigama) 5,079,547 Jan. 07, 1992 Murakami et al. (Murakami) 5,367,335 Nov. 22, 1994 Tahara 5,412,428 May 02, 1995 Lin et al. (Lin) 5,485,214 Jan. 16, 1996 The following rejections are on appeal before us: 1. Claims 1 and 13 stand rejected under 35 U.S.C. ' 102(b) as being anticipated by the disclosure of Murakami. 2. Claims 9 and 21 stand rejected under 35 U.S.C. ' 103(a) as being unpatentable over the teachings of Murakami taken alone. 3. Claims 2, 4-6, 14 and 16-18 stand rejected under Appeal No. 2002-0745 Application 08/893,379 3 35 U.S.C. ' 103(a) as being unpatentable over the teachings of Murakami in view of Lin. 4. Claims 3 and 15 stand rejected under 35 U.S.C. ' 103(a) as being unpatentable over the teachings of Murakami and Lin in view of Fuchigama and Tahara. 5. Claims 7 and 19 stand rejected under 35 U.S.C. ' 103(a) as being unpatentable over the teachings of Murakami and Lin in view of Trew. Rather than repeat the arguments of appellants or the examiner, we make reference to the briefs and the answer for the respective details thereof. OPINION We have carefully considered the subject matter on appeal, the rejections advanced by the examiner and the evidence of anticipation and obviousness relied upon by the examiner as support for the rejections. We have, likewise, reviewed and taken into consideration, in reaching our decision, the appellants= arguments set forth in the briefs along with the examiner=s rationale in support of the rejections and arguments in rebuttal set forth in the examiner=s answer. Appeal No. 2002-0745 Application 08/893,379 4 It is our view, after consideration of the record before us, that the evidence of record does not support any of the examiner=s rejections which are on appeal. Accordingly, we reverse. We consider first the rejection of claims 1 and 13 under 35 U.S.C. ' 102(b) as being anticipated by the disclosure of Murakama. Anticipation is established only when a single prior art reference discloses, expressly or under the principles of inherency, each and every element of a claimed invention as well as disclosing structure which is capable of performing the recited functional limitations. RCA Corp. v. Applied Digital Data Systems, Inc., 730 F.2d 1440, 1444, 221 USPQ 385, 388 (Fed. Cir.); cert. dismissed, 468 U.S. 1228 (1984); W.L. Gore and Associates, Inc. v. Garlock, Inc., 721 F.2d 1540, 1554, 220 USPQ 303, 313 (Fed. Cir. 1983), cert. denied, 469 U.S. 851 (1984). With respect to claims 1 and 13, the examiner has indicated how he reads the two steps of claim 1 and the two means of claim 13 on the disclosure of Murakami [Office action mailed on March 21, 2000]. Appellants argue that Murakami fails to disclose the limitation of [means for] estimating at least one coding parameter used in the previous stage coding process. Specifically, appellants argue that Murakami uses actual coding Appeal No. 2002-0745 Application 08/893,379 5 parameters and does not disclose estimating coding parameters. Appellants also argue that Murakami discloses a single stage coding process and does not relate to tandem stage coding as claimed. Appellants assert that since Murakami is directed to single stage coding which provides the actual previous stage coding, there would be no need to estimate a previous stage coding as claimed [brief, pages 25-28]. The examiner responds that Murakami teaches updating at least one past coding parameter. The examiner notes that since the past coding parameter was slightly wrong, the examiner considers it an estimate within the meaning of claims 1 and 13. The examiner asserts that it is the motion detection information which is estimated and which constitutes the coding parameter [answer, pages 5-6]. Appellants respond that Murakami only discloses updating actual coding parameters and not estimating past coding parameters. Appellants repeat the argument that past coding parameters are available in Murakami so that there is no need to estimate them as asserted by the examiner [first reply brief, pages 6-7]. We will not sustain the examiner=s rejection of claims 1 and 13. We essentially agree with all of appellants= arguments directed to the rejection of these claims. First, it must be Appeal No. 2002-0745 Application 08/893,379 6 noted that the invention of claims 1 and 13 relates to tandem stage coding in which the stages execute the process separately and sequentially. The coding process of Murakami does not relate to tandem stage coding of this type. Second, the later stage coding process must estimate at least one coding parameter used in the previous stage coding process in accordance with picture properties of the video signal coded by the previous stage coding process. The process of Murakami uses the actual coding parameters and measurements of motion in one frame of information to code subsequent frames of information. Thus, as noted by appellants, Murakami relies on actual data from previous calculations to code subsequent frames of data. Although the coding in Murakami may not be completely accurate, each stage of calculation in Murakami relies on the actual data from a previous stage of calculation rather than an estimate of a coding parameter used in the previous stage of calculation. Therefore, we agree with appellants that Murakami does not disclose every feature recited in claims 1 and 13. We now consider the various rejections under 35 U.S.C. ' 103. In rejecting claims under 35 U.S.C. ' 103, it is incumbent upon the examiner to establish a factual basis to support the legal conclusion of obviousness. See In re Fine, Appeal No. 2002-0745 Application 08/893,379 7 837 F.2d 1071, 1073, 5 USPQ2d 1596, 1598 (Fed. Cir. 1988). In so doing, the examiner is expected to make the factual determinations set forth in Graham v. John Deere Co., 383 U.S. 1, 17, 148 USPQ 459, 467 (1966), and to provide a reason why one having ordinary skill in the pertinent art would have been led to modify the prior art or to combine prior art references to arrive at the claimed invention. Such reason must stem from some teaching, suggestion or implication in the prior art as a whole or knowledge generally available to one having ordinary skill in the art. Uniroyal, Inc. v. Rudkin-Wiley Corp., 837 F.2d 1044, 1051, 5 USPQ2d 1434, 1438 (Fed. Cir.), cert. denied, 488 U.S. 825 (1988); Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 293, 227 USPQ 657, 664 (Fed. Cir. 1985), cert. denied, 475 U.S. 1017 (1986); ACS Hosp. Sys., Inc. v. Montefiore Hosp., 732 F.2d 1572, 1577, 221 USPQ 929, 933 (Fed. Cir. 1984). These showings by the examiner are an essential part of complying with the burden of presenting a prima facie case of obviousness. Note In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir. 1992). If that burden is met, the burden then shifts to the applicant to overcome the prima facie case with argument and/or evidence. Obviousness is then determined on the basis of the evidence as a whole and the relative Appeal No. 2002-0745 Application 08/893,379 8 persuasiveness of the arguments. See Id.; In re Hedges, 783 F.2d 1038, 1039, 228 USPQ 685, 686 (Fed. Cir. 1986); In re Piasecki, 745 F.2d 1468, 1472, 223 USPQ 785, 788 (Fed. Cir. 1984); and In re Rinehart, 531 F.2d 1048, 1052, 189 USPQ 143, 147 (CCPA 1976). Each of the claims rejected under 35 U.S.C. ' 103 depends from claim 1 or claim 13. All of the examiner=s rejections under 35 U.S.C. ' 103 rely primarily on the teachings of Murakami as discussed above. The examiner=s findings with respect to Murakami are erroneous for reasons discussed above. None of the additionally applied references against these claims overcomes the deficiencies in Murakami discussed above. Therefore, each of the examiner=s rejections under 35 U.S.C. ' 103 fails to establish a prima facie case of obviousness for at least the limitations recited in claims 1 and 13. Accordingly, we do not sustain any of the examiner=s rejections under 35 U.S.C. ' 103. Appeal No. 2002-0745 Application 08/893,379 9 In summary, we have not sustained any of the examiner=s rejections of the claims on appeal. Therefore, the decision of the examiner rejecting claims 1-7, 9, 13-19 and 21 is reversed. REVERSED Jerry Smith ) Administrative Patent Judge ) ) ) ) BOARD OF PATENT Lee E.
