MacDONALD, AMBER L. HAGY, and KARA L. SZPONDOWSKI, Administrative Patent Judges. MacDONALD, Administrative Patent Judge. DECISION ON APPEAL 1 1 Appellant indicates the real party in interest is Texas Instruments Incorporated of Dallas, Texas, United States of America. App. Br. 2. Appeal 2018-001019 Application 13/917,540 STATEMENT OF THE CASE Appellant appeals under 35 U.S.C. § 134(a) from a Final Rejection of claims 19 and 20. Appellant has cancelled claims 1-18. App. Br. 2. We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM. Claims Claims 19 and 20 under appeal read as follows (emphasis and bracketed material added): 19. A method comprising: [A.] determining, with a video coder that includes one or more processors, a region of a transform block to which a one-dimensional (JD) inverse discrete cosine transformation (IDCT) is to be applied in a first direction based on a group significance map corresponding to the transform block; and [B.] applying, with the video coder, the ID IDCT in the first direction to the determined region of the transform block to generate an interim results block, wherein 1 D IDCT computations are not performed on transform coefficients outside of the region. 20. The method of claim 19, wherein the group significance map includes a plurality of significant coefficient group flags, each of the significant coefficient group flags being indicative of whether a respective one of a plurality of blocks in a significance map includes at least one non-zero transform coefficient. 2 Appeal 2018-001019 Application 13/917,540 Handley et al. Nguyen et al. References US 2008/0232475 Al Sep. 25, 2008 US 2013/0188735 Al Jul. 25, 2013 Rejections 1. The Examiner rejected claim 19 under 35 U.S.C. § 102(b) as being anticipated by Applicant Admitted Prior Art ("AAPA"). 2. The Examiner rejected claims 19 and 20 under 35 U.S.C. § 103(a) as being unpatentable over the combination of Handley and Nguyen. Issues on Appeal Did the Examiner err in rejecting claim 19 as being anticipated? Did the Examiner err in rejecting claims 19 and 20 as being obvious? ANALYSIS We have reviewed the Examiner's rejections in light of Appellant's arguments (Appeal Brief and Reply Brief) that the Examiner has erred. A. Section 102 Argument Appellant raises the following argument in contending that the Examiner erred in rejecting claim 19 under 3 5 U.S. C. § 102 (b). The Examiner alleged that paragraphs [0006] and [0007]2 of the published application for Applicant's disclosure allegedly admit as prior art all of the limitations of claim 19. The Examiner erred, however, because paragraphs [0006] and [0007] make no mention of a "group significance map" in the first place, much disclose "determining a region of a transform block ... based on 2 Paragraphs 6 and 7 of Appellant's published application correspond to paragraphs 4 and 5 of Appellant's application as filed. 3 Appeal 2018-001019 Application 13/917,540 a group significance map," as positively recited in pending claim 19. If paragraphs [0006] and [0007] of the published application for Applicant's disclosure fail to even mention a "group significance map" in the first place, then such paragraphs also fail to admit as prior art any group significance map-based determination. In the Final Office Action, the Examiner pointed to a statement in paragraph [0007] of the published application for Applicant's disclosure, which states "IDCT pruning is a well known technique." However, this statement makes no mention of a "group significance map," and therefore fails to admit as prior art "determining ... a region of a transform block to which a [ID IDCT] is to be applied in a first direction based on a group significance map corresponding to the transform block," as recited in pending claim 19. App. Br. 4. The Examiner responds: [Appellant's] paragraph [0007] makes it clear that "[t]he knowledge that a large portion of a transform block may be zero is exploited for IDCT pruning, also referred to as partial inverse transformation . . . . IDCT pruning is a well known technique supported by existing video coding standards that use a zigzag scan patter to scan coefficients in a transform block." This very language is one of the steps utilized in constructing significance maps in the H.264/ A VC standard, which Appellant's disclosure refers to and is understood by a person having ordinary skill in the art. Examiner also made it of record "paragraph [0006] refers to H.264/ A VC which supports CABAC and thus significance maps." (See Final Rejection point 17). Thus, at minimum, Appellant's admitted prior art enables the determined region of a transform block to be "based on a group significance map". Ans. 5 (emphasis omitted). 4 Appeal 2018-001019 Application I3/9I 7,540 In response to the Examiner's Answer, Appellant further contends that the Examiner erred in rejecting claim I9 under 35 U.S.C. § I02(b) because: The Examiner's logic is flawed ... because it assumes that because the H.264 standard is admitted prior art, then making ID IDCT pruning decisions based on any data structure that is allegedly inherent in the H.264 standard is also admitted prior art. This logic is not sound, and should not be used as the basis for an applicant admitted prior art[§ I02] rejection. Reply Br. 2. We conclude, consistent with Appellant's arguments as to claim I9, there is insufficient articulated reasoning to support the Examiner's findings that AAP A discloses the argued limitations. Therefore, we conclude that there is insufficient articulated reasoning to support the Examiner's findings that claim I 9 is anticipated by AAP A. B. Section 103 Argument 1. Appellant raises the following arguments in contending that the Examiner erred in rejecting claim I9 under 35 U.S.C. § I03(a). Handley et al. identifies optimized sets of transpose operations based on patterns of non-zero coefficients of a 2D- encoded block, and performs the optimized set of transpose operations on a ID-encoded block. No mention is made of a group significance map, much less determining a region of a transform block to which a one-dimensional (ID) inverse discrete cosine transformation (IDCT) is to be applied based on a group significance map. Therefore, Handley et al. fails to disclose or suggest "determining ... a region of a transform block to which a one- dimensional (ID) inverse discrete cosine transformation (IDCT) is to be applied in a first direction based on a group significance 5 Appeal 2018-001019 Application 13/917,540 map corresponding to the transform block," as recited m pending claim 19. App. Br. 7-8 (emphasis added). No mention is made in Nguyen et al. of determining a region of a transform block to which a JD IDCT is to be applied in a first direction based on a group significance map corresponding to the transform block. Therefore, Nguyen et al. fails to overcome the deficiencies discussed above with respect to Handley et al. App. Br. 8 (emphasis added). As to Appellant's contentions regarding claim 19, we disagree. First, Appellant argues the Handley reference fails to disclose or suggest the limitation of a group significance map corresponding to the transform block. However, Examiner did not cite Handley for this limitation. Rather, the Examiner cited Nguyen. Final Act. 12. Then, Appellant argues the Nguyen reference fails to disclose or suggest the limitation of determining a region of a transform block to which a ID IDCT is to be applied. However, Examiner did not cite Nguyen for this limitation. Rather, the Examiner cited Handley. Final Act. 11. We conclude that Appellant's arguments do not address the actual reasoning of the Examiner's rejection. Instead, Appellant attacks each of the Handley and Nguyen references singly for lacking teachings that the Examiner relied on the combination of references to show. It is well established that one cannot show nonobviousness by attacking references individually where the rejections are based on combinations of references. See In re Keller, 642 F.2d 413 (CCPA 1981); In re Merck & Co., 800 F.2d 1091 (Fed. Cir. 1986). This form of argument is inherently unpersuasive to show Examiner error. Our reviewing court requires that references must be 6 Appeal 2018-001019 Application I3/9I 7,540 read, not in isolation, but for what they fairly teach in combination with the prior art as a whole. Merck, 800 F.2d at I097 (Fed. Cir. I986). 2. Appellant also raises the following argument in contending that the Examiner erred in rejecting claim I9 under 35 U.S.C. § I03(a). The Examiner further erred because the Examiner's proposed combination of references for previously presented claim I does not result in a system that "determin[ es] a region of a transform block to which a [ID IDCT] is to be applied ... based on a group significance map," as recited in pending claim I9. Instead, the Examiner's proposed combination would appear, at most, to identify optimized sets of transpose operations based on significant-coefficient flags, which does not correspond to determining regions of a transform block to which a ID IDCT is to be applied, as recited in claim I 9. App. Br. 9-IO (emphasis added). We are unpersuaded by Appellant's above contention. Appellant's argument speculates that the combination of Handley and Nguyen would render obvious "identify[ing] optimized sets of transpose operations based on significant-coefficient flags." App. Br. 9-IO. Even if we were to agree that the cited combination also renders obvious an invention other than the invention of Appellant's claim I9, this is simply not a relevant argument as to whether the Examiner has provided a proper final conclusion that the combination of references renders obvious the claimed invention. A combination of references is not precluded from rendering obvious any number of distinct inventions. 7 Appeal 2018-001019 Application 13/917,540 3. Appellant also raises the following argument in contending that the Examiner erred in rejecting claim 19 under 35 U.S.C. § 103(a). [E]ven if step 1205 in Handley et al. were modified to have the pattern of coefficients identified based on a group significance map, such a process would still perform complete ID IDCTs for the entire transform block in Handley et al. In other words, there would be no regions of the transform block in which an IDCT is not performed. This is because the patterns that are identified in step 1205 serve only to determine what set of transpose operations to use in a transpose step (which is not a 1 D IDCT) of Handley et al. Such patterns are not used in Handley et al. to prune JD IDCT operations or to determine regions to which a JD IDCT is to be applied, and the applied references make no suggestion of using the patterns for such a purpose. Reply Br. 6 (emphasis added). We are unpersuaded that the Examiner erred based on Appellant's above contention. Even if we adopt Appellant's argument that step 1205 of Handley is insufficient to show using identifying patterns to determine regions to which encoding operations are applied, paragraph 53 Nguyen of does teach identifying non-zero coefficients to determine where encoding is to be applied as Examiner points out at page 12 of the Final Action. 4. Appellant also raises the following argument in contending that the Examiner erred in rejecting claim 19 under 35 U.S.C. § 103(a). [T]here is no mention anywhere (in either Handley et al. or Nguyen et al.) of pruning 1 D IDCT operations in general, much less the particular group significance map-based pruning described in pending claim 19. Reply Br. 6 (emphasis added). 8 Appeal 2018-001019 Application 13/917,540 We are unpersuaded by Appellant's above contention. Again, we conclude that Appellant's argument does not address the actual reasoning of the Examiner's rejection. Instead, Appellant attacks each of the Handley and Nguyen references singly for lacking teachings that the Examiner relied on the combination of references to show. 5. Appellant also raises the following argument in contending that the Examiner erred in rejecting claim 20 under 35 U.S.C. § 103(a). Examiner erred because Handley ... in view of Nguyen ... fails to disclose or suggest "determining ... a region of a transform block to which a [ 1 D IDCT] is to be applied in a first direction based on a group significance map corresponding to the transform block ... wherein the group significance map includes a plurality of significant coefficient group flags, each of the significant coefficient group flags being indicative of whether a respective one of a plurality of blocks in a significance map includes at least one non-zero transform coefficient" as positively recited in claims 19 and 20. App. Br. 10. Appellant's contention does not persuade us that the Examiner erred. Appellant merely recites the particular language of claims 19 and 20, and asserts the cited prior art references does not teach or suggest the claim limitations. Without more, this fails to constitute an argument on the merits. See 37 C.F.R. § 41.37(c)(l)(iv); In re Lovin, 652 F.3d 1349, 1357 (Fed. Cir. 2011). 9 Appeal 2018-001019 Application 13/917,540 CONCLUSIONS (1) Appellant has established that the Examiner erred in rejecting claim 19 as being anticipated under 35 U.S.C. § 102(b). (2) The Examiner has not erred in rejecting claims 19 and 20 as being unpatentable under 35 U.S.C. § 103(a). (3) Claims 19 and 20 are not patentable. DECISION The Examiner's rejection of claim 19 as being unpatentable under 35 U.S.C. § 102(b) is reversed. The Examiner's rejection of claims 19 and 20 as being unpatentable under 35 U.S.C. § 103(a) is affirmed. Because we have affirmed at least one ground of rejection with respect to each claim on appeal, the Examiner's decision is affirmed. See 37 C.F.R. § 41.50(a)(l). 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). AFFIRMED 10 Copy with citationCopy as parenthetical citation
