ORLICK, JEROME D. SHIELDS, and SCOTT J. MILLER Appeal2015-006535 Application 13/511,534 Technology Center 2600 Before CATHERINE SHIANG, LINZY T. McCARTNEY, and JAMES W. DEJMEK, Administrative Patent Judges. SHIANG, Administrative Patent Judge. DECISION ON APPEAL Appellants appeal under 35 U.S.C. § 134(a) from the Examiner's rejection of claims 90-105, which are all the claims pending and rejected in the application. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. Appeal2015-006535 Application 13/511,534 STATEMENT OF THE CASE Introduction The present invention relates to controlling backlight panels of dual modulation displays in response to input image data. See generally Spec. 1. Claim 90 is exemplary: 90. A method for determining backlight drive values for backlight elements of a backlight panel of a dual modulation display, said dual modulation display comprising a front panel illuminated by said backlight panel, in response to input image data indicative of an image to be displayed, the method comprising the steps of: (a) determining statistical data indicative of at least one statistical measure of each of a number of spatially compact subsets of pixels of image data, wherein each spatially compact subset of pixels comprises a block whose spatial location in the input image corresponds to a subset of the pixels in said front panel that is illuminated by a subset of said backlight elements, including by performing at least one nonlinear operation on each of the spatially compact subsets, where said front panel having a first resolution, the image data being mapped to the first resolution, the statistical data have resolution lower than the first resolution, and the pixels of image data comprise elements of the group consisting of pixels of the input image data, color components of pixels of the input image data, and data values derived from pixels of the input image data, and band-limiting the statistical data; and (b) determining the backlight drive values from the band- limited statistical data, wherein the statistical data are indicative of the mean and standard deviation of each of the spatially compact subsets, and step (a) comprises a step of determining standard deviation values including by filtering mean values of the spatially compact subsets to determine filtered mean values, and squaring each of the filtered mean values. 2 Appeal2015-006535 Application 13/511,534 References and Rejections Claims 90-97 and 101-103 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Seetzen (US PG-Pub 2007 /0216819 A 1; published Sept. 20, 2007), Fletcher (US PG-Pub 2009/0219244 Al; published Sept. 3, 2009), and Damberg (US PG-Pub 2009/0201320 Al, published Aug. 13, 2009). Claims 98-100 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Seetzen, Fletcher, Damberg, and Kerofsky (US PG-Pub 2009/0267876 Al, published Oct. 29, 2009). Claims 104 and 105 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Seetzen, Fletcher, Damberg, and Kerofsky. ANALYSIS Obviousness On this record, we find the Examiner did not err in rejecting claim 90. We disagree with Appellants' arguments, and agree with and adopt the Examiner's findings and conclusions in (i) the action from which this appeal is taken and (ii) the Answer to the extent they are consistent with our analysis below. 1 Appellants contend Seetzen and Fletcher do not collectively teach "determining statistical data indicative of at least one statistical measure of each of a number of spatially compact subsets of pixels of image data," as 1 To the extent Appellants advance new arguments in the Reply Brief without showing good cause, Appellants have waived such arguments. See 37 C.F.R. § 41.4l(b)(2). 3 Appeal2015-006535 Application 13/511,534 recited in claim 90. See App. Br. 12-15; Reply Br. 2--4. In particular, Appellants assert "Seetzen does not teach, disclose or suggest the use of 'statistical data' anywhere within the reference" and "Fletcher (at paragraphs 0068-0069 and elsewhere) does not disclose the mean and/or standard deviation for any spatially compact subset of pixels." App. Br. 12-13; see also App. Br. 14--15; Reply Br. 2--4. Appellants have not persuaded us of error. In response to the Examiner's explanation in the Answer, Appellants concede "Seetzen utilizes statistics." Reply Br. 2. Additionally, in response to Appellants' arguments, the Examiner provides further findings showing Seetzen and Fletcher collectively teach the disputed claim limitation. See Ans. 3--4. In particular, the Examiner finds: Appellant makes specific reference to [0067]-[0068] in their arguments. However, [0069] of Fletcher states: "Another exemplary algorithm is to calculate the average luma and standard deviation of the Zuma of the image. Then the luma gain of the image may be determined by a number of standard deviations (or other statistical measures) that are desired to be preserved within the image." Further, Fletcher notes at [0071] that the intensity of the backlight can be dynamically calculated to provide different images to be displayed on the screen. At [0072], Fletcher again notes that calculations can be made to determine pixel values. Thus, Fletcher does teach the use calculations of statistical data, utilizing an average and standard deviation, to determine the intensity of the pixels. [Further], Fletcher . .. teaches utilizing the calculated Zuma gain, which is done by using statistical data, on a compact subset of pixels. As provided in [0072], the backlight can adjust the pixel intensity values on selected portions of the display, based on the determined pixel luma value. Additionally, [0080]-[0084] describes how Fletcher can adjust and utilize the statistical data on a portion of 4 Appeal2015-006535 Application 13/511,534 the display pixels. . . . l 0082 J notes that an adjustment may be made on selected pixels, which shows that a subset of pixels may be adjusted due to statistical data. Ans. 3--4 (emphases added).2 Appellants fail to persuasively respond to such findings and therefore, fail to show error in the Examiner's findings. See In re Baxter Travenol Labs., 952 F.2d 388, 391 (Fed. Cir. 1991) ("It is not the function of this court [or this Board] to examine the claims in greater detail than argued by an appellant, looking for [patentable] distinctions over the prior art."). In particular, Appellants do not critique the Examiner's finding that "Fletcher does teach the ... calculations of statistical data, utilizing an average and standard deviation" (Ans. 3). Likewise, Appellants do not persuasively respond to the Examiner's findings that "spatially compact subsets of pixels of image data" are taught by or would have been obvious in light of Fletcher's teachings. See Ans. 4; Fletcher i-f 72 ("adjust the pixel intensity values of selected portion(s) of the image"); i182 ("an adjustment is applied to the selected pixels in the image"). 3 2 Appellants' argument about "a single pixel scenario" (Reply Br. 4) is inadequate for showing reversible error, because of the Examiner's findings based on Fletcher's paragraphs 72 and 82, which teach more than a single pixel. 3 Cumulatively, the Examiner cites Fletcher's paragraph 68, which states: "One exemplary algorithm which may be implemented to determine a percentage is to analyze all or part of the histogram." Fletcher i-f 68 (emphasis added). Appellants' argument that the cited Fletcher portions "does not necessarily teach the use of 'statistical data' on a 'compact subset of pixels"' (App. Br. 14 (emphasis added)) is unpersuasive: in an obviousness determination, the Examiner does not need to show the reference necessarily teaches the disputed claim limitation. In any event, Appellants have not persuasively shown how their interpretation of the cited 5 Appeal2015-006535 Application 13/511,534 Further, Appellants argue: The Answer/Office Actions do not cite any corresponding structure and/ or teaching in Fletcher wherein the required statistical data of blocks corresponding to subsets of pixels illuminated by a subset of backlight elements is taught or suggested. [T]he limitations of Claim 90 noted above that "each compact subset of pixels" comprise: (1) "a block"; (2) "whose spatial location"; (3) "corresponds to a subset of the pixels in said front panel"; and (4) "that is illuminated by a subset of said backlight elements". And, for each of these "compact subset of pixels", Claim 90 yet further requires that statistical data be determined and then applied to the backlight elements ("determining the backlight values from the ... statistical data [determined for] each of the spatially compact subsets'') - thereby effecting dual modulation on a block-by-block basis. [E]ven if Fletcher's histogram were deemed some type of block based statistic, the histogram is not applied to elements of the backlight, which, as noted above, are absent from Fletcher. Reply Br. 2--4. Appellants' arguments are unpersuasive, because the Examiner finds-and Appellants fail to offer any substantive argument to dispute- "wherein each spatially compact subset of pixels comprises a block whose spatial location in the input image corresponds to a subset of the pixels in said front panel that is illuminated by a subset of said backlight elements" and "determining the backlight drive values" are taught by or would have been obvious in light of Seetzen's teachings. See Final Act. 3--4; Baxter Travenol Labs., 952 F .2d at 391. In the Reply and for the first time, Appellants belatedly argue: Fletcher portion (App. Br. 15) is correct, as Appellants do not cite any evidence to support their interpretation (App. Br. 15). 6 Appeal2015-006535 Application 13/511,534 [T]he Otlice Actions and the Answer each fail to provide a rational underpinning to modify Seetzen and/or Damberg to include the limitations of Fletcher, and thus each have failed to establish a prima facie case of obviousness for the rejection of claims 90 et al. .... Reply Br. 4. Appellants have waived such arguments because they are untimely, and Appellants have not demonstrated any "good cause" for the belated presentation. See 37 C.F.R. § 41.41(b)(2) (2012). Because Appellants have not persuaded us the Examiner erred, we sustain the Examiner's rejection of claim 90, and corresponding dependent claims, which Appellants do not separately argue. Appellants argue independent claims 103-105 are patentable for similar reasons discussed above with respect to claim 90. See App. Br. 16- 17. Therefore, for similar reasons discussed above with respect to claim 90, we sustain the Examiner's rejection of claims 103-105. DECISION We affirm the Examiner's decision rejecting claims 90-105. 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 7 Copy with citationCopy as parenthetical citation
