NAPPI, ERIC S. FRAHM, and MICHAEL T. CYGAN, Administrative Patent Judges. CYGAN, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF CASE Introduction Appellant appeals under 35 U.S.C. § 134(a) from the Examiner's Final Rejection of claims 1, 2, 7-15, 18, 19, 21-25, 27, and 28 We have jurisdiction under 35 U.S.C. § 6(b). We affirm. 1 According to Appellant, the real party in interest is the University of Houston System. App. Br. 3. Appeal2018-005726 Application 13/852,672 Disclosed Invention and Exemplary Claim The disclosed invention is a handheld imaging device ( claim 1) having algorithms to identify an object of interest present on a body, a method ( claim 10), of using the handheld imaging device of claim 1 to identify an object of interest, a digital processor-implemented system ( claim 14) and method (claim 22) for classifying an object of interest on a body, and a non-transitory computer-readable medium storing a library of algorithms to classify an object of interest on a body (Spec. ,r,r 8-13; claims 1, 10, 14, 22, 25). Independent claim 1 is exemplary of the disclosed invention, and reads as follows ( with key limitations of the claim emphasized): 1. A portable imaging system, comprising: a hand-held imaging device having a digital camera, a display, a memory, a processor and a network connection; and a library of algorithms tangibly stored in the memory and executable by the processor, said algorithms configured for identification of an object of interest present on a body via processor-executable instructions that function to: segment the imaged object to detect a border of the object via steps to: determine an initial contour of the imaged object; classify pixels as contained within the initial contour as foreground, as contained without the initial contour as background or as remaining pixels if they are not classified as foreground pixels or background pixels; and apply a supervised classifier to the remaining pixels for classification as foreground or background; extract features from the segmented object image via steps to: divide the segmented object image into regions based on saliency values calculated for at least one patch within the segmented object; 2 Appeal2018-005726 Application 13/852,672 divide the regions into two regions of higher or lower intensity based on average intensity values thereof; and extract feature representations from a sampling of patches within the intensity regions based on sampling percentages determined for the regions; classify the object based on the extracted features via steps to: input the extracted feature representations into a support vector machine trained with manually segmented objects; and classify the object based on a comparison of the inputted extracted features with those in the trained support vector machine. Remaining independent claims 14 and 25 recite limitations commensurate with the above-emphasized limitations recited in claim 1. Examiner's Rejections (1) The Examiner rejected claims 1, 2, 7-15, 18, 21-25, and 27 under 35 U.S.C. § I03(a) as being obvious over the combination Zouridakis et al. (US 2008/0226151 Al; published September 18, 2008), Guyon et al. (US 2012/0008838 Al; published January 12, 2012), and Wilensky et al., (US 2008/0095429 Al; published April 24, 2008). Final Act. 4--12; Ans. 2- 6. (2) The Examiner rejected claims 19 and 28 under 35 U.S.C. § I03(a) as being obvious over the combination of Zouridakis, Guyon, Wilensky, and Hattery et al., (US 2005/0273011 Al; published December 8, 2005). Final Act. 12-14; Ans. 6. Appellant's Contentions As to independent claims 1, 14, and 25, Appellant contends, inter alia (see generally App. Br. 8-14) the following: 3 Appeal2018-005726 Application 13/852,672 (1) the incorporation of the Guyon and/or Wilensky algorithms into Zouridakis' device would result in a device performing a step of merging regions into small clusters that is not required by Appellant's claimed invention (App. Br. 1-13); (2) the incorporation of the Guyon and/or Wilensky algorithms into Zouridakis' device would result in a device that classifies pixels based on a foreground or background color, instead of classifying pixels into foreground, background or remaining pixels as required by Appellant's claimed invention (App. Br. 13); and (3) the combination of Zouridakis, Wilensky, and Guyon would result in a user-controlled extraction and classification of pixels, instead of the claimed invention's use of an algorithm to extract and classify the pixels (App. Br. at 13-14). Appellant relies on these contentions as to the patentability for claims 1, 2, 7-15, 18, 21-25, and 27. Based upon Appellant's contentions, and because claims 1, 2, 7-15, 18, 21-25, and 27 contain commensurate limitations, we select claim 1 as representative of claims 1, 2, 7-15, 18, 21- 25, and 27 rejected over the base combination of Zouridakis, Guyon, and Wilensky. Issues on Appeal The primary issue on appeal is whether the Examiner erred in rejecting claims 1-2, 7-15, 18, 21-25, and 27 under 35 U.S.C. § 103(a) over the base combination of Zouridakis, Guyon, and Wilensky, because the base combination fails to teach or suggest the following limitation (italicized 4 Appeal2018-005726 Application 13/852,672 below) recited in independent claim 1 (and as commensurately recited in remaining independent claims 14 and 25): ... algorithms configured for identification of an object of interest present on a body via processor-executable instructions that function to: segment the imaged object to detect a border of the object via steps to: determine an initial contour of the imaged object; classify pixels as contained within the initial contour as foreground, as contained without the initial contour as background or as remaining pixels if they are not classified as foreground pixels or background pixels . .. Claim 1 ( emphasis added). ANALYSIS We have reviewed the Examiner's rejections (Final Act. 4--14) in light of Appellant's contentions in the Appeal Brief that the Examiner has erred (App. Br. 8-17). We disagree with Appellant's arguments. With regard to representative claim 1, we adopt as our own (1) the findings and reasons set forth by the Examiner in the action from which this appeal is taken (Final Act. 6-10), and (2) the reasons set forth by the Examiner in the Examiner's Answer (Ans. 3-7) in response to Appellant's Appeal Brief. We concur with the findings and conclusions reached by the Examiner as to the obviousness rejection of claim 1. Appellant first contends that the incorporation of the Guyon and/ or Wilensky algorithms into Zouridakis' device would result in a device performing a step of merging regions into small clusters that is not required by Appellant's claimed invention (App. Br. 1-13). However, this contention 5 Appeal2018-005726 Application 13/852,672 is unpersuasive as failing to be commensurate in scope with the language of representative claim 1. See In re Hiniker Co., 150 F.3d 1362, 1369 (Fed. Cir. 1998) ("[The] proffered facts ... are not commensurate with the claim scope and are therefore unpersuasive."); In re Self, 671 F.2d 1344, 1348 (CCPA 1982) (limitations not appearing in the claims cannot be relied upon for patentability). The language of claim 1 recites a step of determining an initial contour of the imaged object, but does not limit the manner of its performance such that it cannot be performed through merging regions into small clusters to determine the initial contour. As explained by the Examiner, the use of an algorithm based upon finding a curve to segment an image into two regions based on intensity within those regions, and more particularly, the use of the Chan-Vese model in such segmentation, is common both to Appellant's disclosure and to the teachings of Zouridakis. Ex. Ans. at 3. The Examiner thus concludes that Zouridakis teaches or suggests the claimed "segment the imaged object to detect a border of the object via steps to[] determine an initial contour of the imaged object." Id. Although the claim does not require regions to be merged into small clusters during the segmentation, no negative limitation exists in the claims that would exclude merging regions into small clusters in performance of the step of determining the initial contour of the imaged object. 2 2 It is further noted that independent claims 15 and 25 do not require any step of determining the initial contour of the imaged object; similarly, those claims lack limitation that would exclude merging regions into small clusters. 6 Appeal2018-005726 Application 13/852,672 Appellant next contends that the incorporation of the Guyon and/or Wilensky algorithms into Zouridakis' device would result in a device that classifies pixels based on a foreground or background color, instead of classifying pixels into foreground, background or remaining pixels as required by Appellant's claimed invention (App. Br. 13). However, this contention is unpersuasive because, as explained by the Examiner, Wilensky teaches segmentation of the image into three separate regions: foreground, uncertain, and background. Final Act. 6; Ex. Ans. 4. The test for obviousness is "what the combined teachings of the references would have suggested to those of ordinary skill in the art." In re Keller, 642 F.2d 413,425 (CCPA 1981). Here, Appellant asserts that the combination would result in a device that classifies pixels based on a foreground or background color, but does not provide reasoning to explain that bare assertion. App. Br. 13. In view of the facts and reasoning presented, we find that one having ordinary skill in the art would find the that the combination of the Zouridakis, Guyon, and Wilensky references teach or suggest the claimed classification of pixels into foreground, background, or remaining pixels. Appellant also contends that the teaching of Wilensky is for user- performed operation rather than the claimed algorithm-performed operation, stating, "the claimed invention requires that the algorithm extracts and classifies the foreground, background, and remaining pixels." App. Br. 13- 14. However, as noted by the Examiner, Wilensky teaches "[t]he algorithm then segments the entire image or a portion of the image bounding the selection into three separate regions: foreground, uncertain, and background." Wilensky Jr 52; Ex. Ans. 5. 7 Appeal2018-005726 Application 13/852,672 Appellant's contention is unpersuasive as failing to be commensurate in scope with the language of representative claim 1. See In re Hiniker Co., 150 F.3d 1362, 1369 (Fed. Cir. 1998) ("[The] proffered facts ... are not commensurate with the claim scope and are therefore unpersuasive."); In re Self, 671 F.2d 1344, 1348 (CCPA 1982) (limitations not appearing in the claims cannot be relied upon for patentability). The language of claim 1 requires that the algorithm, via processor-executable instructions, classify pixels as foreground, background, or as remaining pixels. Claim 1 does not contain any language excluding user input in the instructions of the algorithms in any of the recited steps, including the step of classifying the pixels. Nor does claim 1 contain any language concerning the "extract[ion ]" of pixels as contended by Appellant. In this light, Appellant's contention that Wilensky fails to teach or suggest an algorithm having processor- executable instructions that function to segment than imaged object via steps to determine an initial contour of the imaged object and to classify pixels therein is unpersuasive. In view of the foregoing, we sustain the Examiner's obviousness rejection of claim 1, as well as claims 2, 7-15, 18, 21-25, and 27 grouped therewith. As to the rejection of dependent claims 19 and 28 as being obvious over the combination of Zouridakis, Wilensky, Guyon, and Hattery, Appellant's brief presents the same arguments presented concerning the rejection of the respective independent claims 15 and 25 as being obvious over the combination of Zouridakis, Wilensky, and Guyon. We decide the outcome of claims 19 and 28 on the same basis as claims 15 and 25 from which claims 19 and 28 depend, which in tum we decide on the basis of 8 Appeal2018-005726 Application 13/852,672 representative claim 1. Therefore, Appellant has not shown that the Examiner erred in rejecting claims 19 and 28. See 37 C.F.R. § 41.37( C )(1 )(iv). CONCLUSIONS ( 1) We conclude that the Examiner did not err in rejecting claims 1, 2, 7-15, 18, 21-25, and 27 under 35 U.S.C. § 103(a) over the base combination of Zouridakis, Wilensky, and Guyon. (2) We conclude that Appellant has not shown that the Examiner has erred in rejecting claims 19 and 28 under 35 U.S.C. § 103(a) as being obvious over the combination of Zouridakis, Wilensky, Guyon, and Hattery. DECISION We affirm the Examiner's rejections of claims 1, 2, 7-15, 18, 19, 21- 25, 27, and 28 under 35 U.S.C. § 103(a). 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 9 Copy with citationCopy as parenthetical citation
