DECISION ON APPEAL2 1 The real party in interest is Thomson Licensing S.A. 2 The two-month time period for filing an appeal or commencing a civil action, as recited in 37 C.F.R. § 1.304, or for filing a request for rehearing, as recited in 37 C.F.R. § 41.52, begins to run from the “MAIL DATE” (paper delivery mode) or the “NOTIFICATION DATE” (electronic delivery mode) shown on the PTOL-90A cover letter attached to this decision. Appeal 2009-006782 Application 10/479,537 2 STATEMENT OF THE CASE Appellants appeal under 35 U.S.C. § 134 (a) from a Final Rejection of claims 1-21. We have jurisdiction under 35 U.S.C. § 6(b). We reverse. Appellants’ invention relates to a video data coder-decoder (“CODEC”) that employs discrete cosine transform ("DCT") based manipulation of video data that is organized as macro blocks. Moving Picture Experts Group’s (MPEG) standard, MPEG-4, for streaming video includes fine-grain scalability ("FGS") that uses a minimum-bitrate previous frame for motion compensation. In alignment with this standard, the encoder chooses between the minimum-bitrate previous frame and a higher- bitrate previous frame for each macroblock. The encoder tracks the accumulated prediction drift at each frame. For a given macroblock, if using the higher-bitrate previous frame for motion compensation results in a prediction drift energy above a maximum limit, the encoder chooses the minimum-bitrate previous frame to predict that macroblock. Otherwise, the encoder chooses the higher-bitrate previous frame to predict the macroblock. The encoder sets a bit (flag) in the coded macroblock to convey to the decoder which version of the previous frame was used for the prediction (Abstract; Spec. 2:23-3:4) Claim 6 is exemplary: 6. A fine-grain scalable video data apparatus for receiving encoded video macroblock data wherein each macroblock is capable of being represented by DCT coefficients representing a minimum bitrate version of the macroblock data and DCT coefficients representing an intermediate bitrate version of the macroblock data, the apparatus comprising a decoder for decoding one of the intermediate and minimum bitrate encode DCT data for each macroblock received from an encoder to produce reconstructed Appeal 2009-006782 Application 10/479,537 3 macroblock data responsive to a predicted energy of an accumulated predicted drift error frame. The prior art relied upon by the Examiner in rejecting the claims on appeal is: Radha US 6,292,512 B1 Sep. 18, 2001 Watanabe US 6,668,071 B1 Dec. 23, 2003 Wu US 2002/0150158A1 Oct. 17, 2002 Shipeng, Experimental Results with Progressive Fine Granularity Scalable (PFGS) Coding, International Organisation For Standardisation Organisation Internationalede Normalisation, ISO/IEC JTC1/SC29/WG11, Coding of Moving Pictures and Audio, March 2000, pp. 14-27 Claims 12-16 stand rejected under 35 U.S.C. § 101 as being directed to non-statutory subject matter. Claims 6, 11, and 16 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Wu in view of Radha. Claims 1-4, 7-9, 12-14, and 17-19, and 21 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Wu in view of Radha. Claim 5 stands rejected under 35 U.S.C. § 103(a) as being unpatentable over Wu in view of Radha and Watanabe. Claims 10, 15, and 20 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Wu in view of Radha and Li. Rather than repeat the arguments of Appellants or the Examiner, we make reference to the Appeal Brief (filed Apr. 3, 2008), the Reply Brief (filed Aug. 21, 2008), and the Examiner’s Answer (mailed July 15, 2008) for their respective details. Appeal 2009-006782 Application 10/479,537 4 ISSUES Appellants contend that the claims include descriptive material that is recorded on a computer readable medium (App. Br. 16). Appellants assert that the Specification discloses that the application program is tangibly embodied on a program storage unit, wherein the program may be uploaded to, and executed by, a machine comprising any suitable architecture having a computer platform that includes hardware such as one or more central processing units ("CPU"), a random access memory ("RAM"), and input/output ("I/On) interfaces (App. Br. 17). Appellants argue further that, although Wu discloses “‘drifting errors,’” Wu does not even remotely mention "‘predicted energy;’” nor "‘predicted energy of an accumulated predicted drift error frame,’" as recited in the claims (App. Br. 22). Appellants’ contentions present us with the following two dispositive issues: 1. Whether a claim reciting “program storage device readable by machine” defines a computer-readable medium or computer-readable memory that becomes functional descriptive material when software is tangibly embodied upon it and, thereby, represents statutory subject matter? 2. Do the references disclose producing “a reconstructed macroblock data responsive to a predicted energy of an accumulated predicted drift error frame”? Appeal 2009-006782 Application 10/479,537 5 FINDINGS OF FACT The following Findings of Fact (FF) are shown by a preponderance of the evidence. The Invention 1. An adaptive motion compensation method may be implemented as software tangibly embodied on a program storage unit. The software application may be uploaded and executed by a machine which is implemented on a computer platform having a CPU, RAM, I/O interfaces, an operating system, and microinstruction code (Spec. 7:25-35). 2. "Accumulated predicted drift error frame energy" as a measure of accumulated error of prediction between an encoder and decoder in a frame due to a mismatch between the reference picture used in the encoder and decoder for FGS enhancement layer coding (Spec. 1:22-26; 6:13-17; and 6:28-7:12). Wu 3. Wu discloses a motion-compensated video encoding scheme that employs progressive fine-granularity layered coding to encode macroblocks of video data into frames having multiple layers including a base layer and enhancement layers. Drifting errors are estimated during the encoding and chooses a coding mode for each macroblock in the enhancement layer to maximize high coding efficiency while minimizing drifting errors (Abstract). Appeal 2009-006782 Application 10/479,537 6 PRINCIPLES OF LAW Patentability Under § 101, there are four categories of subject matter that are eligible for patent protection: (1) processes; (2) machines; (3) manufactures; and (4) compositions of matter. 35 U.S.C. § 101. But even if a claim fits “within one or more of the statutory categories, it may not be patent eligible.” In re Ferguson, 558 F.3d 1359, 1363 (Fed. Cir. 2009). “[A]n applicant may show that a process claim satisfies § 101 either by showing that his claim is tied to a particular machine, or by showing that his claim transforms an article” into a different state or thing. In re Bilski, 545 F.3d 943, 961 (Fed. Cir. 2008) (en banc), cert. granted, 77 U.S.L.W. 3442, 3653, 3656 (U.S. June 1, 2009) (No. 08-964); see also Gottschalk v. Benson, 409 U.S. 63, 70 (1972). “[A] machine is a ‘concrete thing, consisting of parts, or of certain devices and combination of devices.’ This ‘includes every mechanical device or combination of mechanical powers and devices to perform some function and produce a certain effect or result.’” Ferguson, 558 F.3d at 1364 (quoting In re Nuijten, 500 F.3d 1346, 1355 (Fed. Cir. 2007), reh’g denied en banc, 515 F.3d 1361 (Fed. Cir. 2008), and cert. denied, 129 S. Ct. 70 (2008)). Obviousness On the issue of obviousness, the Supreme Court has stated that “the obviousness analysis cannot be confined by a formalistic conception of the words teaching, suggestion, and motivation.” KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 419 (2007). Further, the Court stated “[t]he combination of Appeal 2009-006782 Application 10/479,537 7 familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.” Id. at 416. ANALYSIS § 101 Rejection of Claims 12-16 We select claim 12 as representative of this group, pursuant to our authority under 37 C.F.R. § 41.37(c)(1)(vii). Representative claim 12 recites “[a] program storage device readable by machine, tangibly embodying a program of instructions executable by the machine to perform steps for performing fine-grain scalable video data operations.” We consider Appellants’ arguments to be persuasive to show Examiner error. Specifically, we do not agree with the Examiner’s finding that the claim does not define a computer-readable medium or computer- readable memory and is thus non-statutory for that reason (Ans. 3). The issue thus turns on whether the Examiner properly determined that “[a] program storage device readable by machine” as it is recited in claim 12 is not the same as including “recorded on a computer-readable medium” in the preamble of the claim. Computer programs and data structures are deemed “functional descriptive material,” which impart functionality when employed as a computer component. When functional descriptive material is recorded on some computer-readable medium, it becomes structurally and functionally interrelated to the medium and will be statutory in most cases since use of technology permits the function of the descriptive material to be realized. Appeal 2009-006782 Application 10/479,537 8 Compare In re Lowry, 32 F.3d 1579, 1583-84 (Fed. Cir. 1994) (claim to data structure stored on a computer readable medium that increases computer efficiency held statutory) with In re Warmerdam, 33 F.3d 1354, 1361-62 (Fed. Cir. 1994) (claim to computer having a specific data structure stored in memory held statutory product-by-process claim but claim to a data structure that referred to ideas reflected in nonstatutory process rather than referring to a physical arrangement of the contents of a memory held nonstatutory). The Specification discloses that a software application may be tangibly embodied on a program storage unit and that the application may be uploaded and executed by a machine (FF 1). The Specification provides that the machine is implemented on a computer platform having a CPU, RAM, I/O interfaces, an operating system, and microinstruction code (FF 1). Hence, we find that the “program storage device readable by machine” as disclosed in the Specification is equivalent to a computer-readable medium. We, therefore, find that the Examiner has not met the burden of proof to prove that claim 12 is directed to nonstatutory subject matter, since the claim and Specification disclose the computer program recorded on a computer-readable medium (FF 1). Thus, we reverse the Examiner’s rejection of claims 12-16 under 35 U.S.C. § 101 as being directed to nonstatutory subject matter. 103 Rejection of Claims 1-4, 6-9, 11-14, 16-19, and 21 Independent claims 1, 7, 12, and 17 recite predicting “whether a decoded version of the intermediate bitrate macroblock data has an Appeal 2009-006782 Application 10/479,537 9 accumulated predicted drift error frame energy exceeding a maximum threshold.” Independent claim 6 recites producing “reconstructed macroblock data responsive to a predicted energy of an accumulated predicted drift error frame.” Independent claims 11 and 16 recite a similar claim limitation. We consider Appellants’ arguments summarized supra to be persuasive to show Examiner error. Specifically, we do not agree with the Examiner’s finding that “[e]nergy is the computation of prediction error, which Wu teaches in the use of layers where such computation takes place” (Ans. 15). The Specification discloses that "accumulated predicted drift error frame energy" is a measure of accumulated error of prediction between an encoder and decoder in a frame due to a mismatch between the reference picture used in the encoder and decoder for FGS enhancement layer coding (FF 2). Wu discloses a video encoding scheme that estimates drifting errors during the encoding and chooses a coding mode for each macroblock in the enhancement layer to maximize high coding efficiency while minimizing drifting errors (FF 3). Although Wu discloses minimizing drifting errors, Wu and Radha are silent as to producing “reconstructed macroblock data responsive to a predicted energy of an accumulated predicted drift error frame” (emphasis added). Further, Wu and Radha are silent as to predicting “whether a decoded version of the intermediate bitrate macroblock data has an accumulated predicted drift error frame energy exceeding a maximum threshold” (emphasis added). Therefore, we find that the Examiner has not established the prima facie obviousness of the claims, because the combination of Wu and Radha does not disclose a decoder that produces “reconstructed macroblock data Appeal 2009-006782 Application 10/479,537 10 responsive to a predicted energy of an accumulated predicted drift error frame.” As a result, we will not sustain the Examiner’s § 103 rejection of independent claims 1, 6, 7, 11, 12, 16, and 17, nor that of dependent claims 2-4, 8-9, 13-14, 18-19, and 21. 103 Rejection of Claims 5, 10, 15, and 20 As noted supra, we reversed the rejection of claim 1, 7, 12, and 17 from which claims 5, 10, 15, and 20 respectively depend. If an independent claim is nonobvious under 35 U.S.C. 103, then any claim depending therefrom is nonobvious. In re Fine, 837 F.2d 1071, 1076 (Fed. Cir. 1988). We therefore reverse the Examiner’s rejections of claims 5, 10, 15, and 20 under 35 U.S.C. § 103, for the same reasons expressed with respect to the § 103 rejection of parent claims 1, 7, 12, and 17, supra. CONCLUSION A claim reciting “program storage device readable by machine” defines a computer-readable medium which becomes functional descriptive material when software is tangibly embodied upon and, therefore, is directed to statutory subject matter. The references do not disclose producing “a reconstructed macroblock data responsive to a predicted energy of an accumulated predicted drift error frame.” Appeal 2009-006782 Application 10/479,537 11 ORDER The Examiner’s rejection of claims 1-21 is reversed.
