BENITEZ Appeal 2015-005681 Application 12/668,718 Technology Center 2400 Before JOSEPH L. DIXON, JUSTIN BUSCH, and CARL L. SILVERMAN, Administrative Patent Judges. BUSCH, Administrative Patent Judge. DECISION ON APPEAL This is a decision on appeal under 35 U.S.C. § 134(a) of the rejection of claims 1—24. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. Appeal 2015-005681 Application 12/668,718 CLAIMED SUBJECT MATTER Claims 1,12, and 24 are independent claims. The claims relate generally to three dimensional object modeling using two-dimensional images and, more specifically, to applying multiple depth acquisition functions to the same set of two or more two-dimensional images to improve the accuracy of three-dimensional information. Spec. 1:6—10, 3:20-31. Claim 1 is reproduced below: 1. A three-dimensional acquisition method comprising: acquiring at least two two-dimensional images of a scene; applying a first depth acquisition function to the at least two two-dimensional images; applying a second depth acquisition function to the same at least two two-dimensional images; combining an output of the first depth acquisition function with an output of the second depth acquisition function; and generating a disparity map from the combined output of the first and second depth acquisition functions. REJECTIONS Claims 1, 2, 5, 6, 8—15, 17, 18, and 20-24 stand rejected under 35 U.S.C. § 103(a) as unpatentable in view of Jones (US 7,567,703 B2; July 28, 2009). Non-Final1 Act. 2—5. 1 Although this Appeal is taken from the Final Action mailed on June 30, 2014, the statement of rejection in the Final Action merely refers to the rejection made in the Non-Final Action, mailed on November 7, 2013. Final Act. 4. Accordingly, we reference the Non-Final Action for purposes of identifying the Examiner’s findings regarding the pending rejection. 2 Appeal 2015-005681 Application 12/668,718 Claims 3, 4, and 16 stand rejected under 35 U.S.C. § 103(a) as unpatentable in view of Jones and Ha (US 7, 944, 444 B2; May 17, 2011). Non-Final Act. 5—6. Claims 7 and 19 stand rejected under 35 U.S.C. § 103(a) as unpatentable in view of Jones, Ha, and V. Michael Bove, Jr., Probabilistic Method for Integrating Multiple Sources of Range Data, 7 J. Optical Soc’y Am. 2193 (Dec. 1990) (“Bove”). Non-Final Act. 6—7. OPINION Appellant argues Jones does not disclose applying two depth acquisition functions to the same at least two two-dimensional images. Br. 5—6. There appears to be no dispute regarding this point because the Examiner acknowledges that Jones fails to disclose applying first and second depth acquisition functions to the same at least two two-dimensional images. Non-Final Act. 2—4, 5; see also, e.g., Ans. 9 (“Jones et al discloses all of the claimed invention with the only exception of applying the second depth acquisition functions to the same at least two two-dimensional images.”). Appellant also argues the Examiner fails to provide a sufficient rationale for modifying Jones, basing the proposed combination only on impermissible hindsight. Br. 6—7. Appellant further asserts “the mere fact that a prior art device could (in hindsight) be modified to produce a claimed invention is not a basis for an obviousness rejection unless the prior art suggests the desirability of such a modification.” Id. at 7 (citing In re Laskowski, 871 F.2d 115 (Fed. Cir. 1989). The Examiner explains that the difference between Appellant’s claims and Jones are minor, and concludes it would have been obvious to recognize that the two depth acquisition functions “functioning separately (using at 3 Appeal 2015-005681 Application 12/668,718 least four of two dimensional images) can very well be substituted for” the two depth acquisition functions “functioning together (using at least two dimensional images), just as long as the end result remains substantially the same.” Non-Final Act. 3; Ans. 9. In response to Appellant’s contention that the conclusion of obviousness is based only on impermissible hindsight, the Examiner reiterates the above-quoted statement about the depth acquisition functions acting together instead of independently and states it would have been obvious “in order to provide an effective single representation of the depth information (3D structure) of the scene.” Ans. 11. The Federal Circuit has stated that “rejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006), cited with approval in KSR Int’l Co., 550 U.S. 398, 418 (2007). Obviousness, however, does not require a specific teaching, suggestion, or motivation from the cited art. KSR Int’l Co., 550 U.S. at 401 (noting that an obviousness analysis “need not seek out precise teachings directed to the challenged claim’s specific subject matter, for a court can consider the inferences and creative steps a person of ordinary skill in the art would employ”). In determining the differences between the prior art and the claims, the question under 35 U.S.C. § 103 is not whether the differences themselves would have been obvious, but “whether the claimed invention as a whole would have been obvious.” Stratoflex, Inc. v. Aeroquip Corp., 713 F.2d 1530 (Fed. Cir. 1983). The Supreme Court has held that in analyzing an obviousness rationale, a court need not find specific teachings, but rather 4 Appeal 2015-005681 Application 12/668,718 may consider “the background knowledge possessed by a person having ordinary skill in the art.” See KSR Int’l Co. v. Teleflex Inc., 550 U.S. at 418 (quoting In re Kahn, 441 F.3d at 988). Further, an artisan is presumed to possess both skill and common sense. See KSR, 550 U.S. at 421 (“A person of ordinary skill is also a person of ordinary creativity, not an automaton.”). We agree with Appellant that the end result in Jones being the same as the end result of Appellant’s claims is not enough, by itself, to render Appellant’s claims obvious. However, it is relevant to our consideration of the scope and content of the prior art and the differences between that prior art and Appellant’s claims. See Graham v. John Deere Co., 383 U.S.l, 17 (1966). Appellant admits that various depth acquisition techniques for generating 3D models, each with their own benefits and disadvantages, were well known, even stating that the different methods “have been extensively studied for decades.” See, e.g., Spec. 1:13—3:16. Appellant characterizes the invention as “combining multiple 3D acquisition methods for the accurate recovery of 3D information.” Id. at 8:19—20. As explained by the Examiner, Jones describes applying a first depth acquisition function to one pair of images and a second depth acquisition function to another pair of images, and uses the combined output of the two functions2 to generate a single disparity map. See Non-Final Act. 2—3 (citing 2 We note that, although Jones does not explicitly state whether the same or different depth acquisition functions are applied to each of its image pairs, claim 1 does not recite that the first and second depth acquisition functions are different from each other. Regardless, Appellant does not dispute that Jones discloses “applying a first depth acquisition function to the at least two two-dimensional images” and “applying a second depth acquisition function to ... at least two two-dimensional images.” 5 Appeal 2015-005681 Application 12/668,718 Jones 5:47—63). Jones also explains that “where there are multiple estimates of the same disparity, it should be possible to obtain a more accurate value,” and “by merging disparity maps from different viewpoints, a more complete representation of the scene can be obtained.” Id. at 5:14—18 (emphases added). We are not persuaded by Appellant’s argument that the Examiner does not provide a rationale for modifying Jones and that the modification is based only on impermissible hindsight. The Examiner provided some reasoning in the initial rejection and expanded upon that reasoning in the Answer, to which Appellant did not respond. Considering the broad scope of Appellant’s independent claims and the identified difference between those claims and the prior art, we determine the Examiner has sufficiently articulated a reason with a rational underpinning for modifying Jones to arrive at Appellant’s independent claims—namely, “in order to provide an effective single representation of the depth information (3D structure) of the scene.” See Ans. 11; see also In re Kahn, 441 F.3d at 988, cited with approval in KSR, 550 U.S. at 418. Accordingly, Appellant has not presented a sufficient persuasive showing of error in the Examiner’s factual findings or conclusion of obviousness, and we sustain the Examiner’s rejection of independent claims 1, 12, and 24. The Examiner also finds Jones teaches the additional limitations recited in dependent claims 2, 5, 6, 8—11, 13—15, 17, 18, and 20—23, which ultimately depend from one of claims 1 and 12. Non-Final Act. 4—5. The Examiner finds the combination of Jones and Ha or Jones, Ha, and Bove teaches or suggests the subject matter recited in dependent claims 3, 4, 7, 16, and 19, which ultimately depend from independent claims 1 or 12. 6 Appeal 2015-005681 Application 12/668,718 Non-Final Act. 5—7; Ans. 6—8. Appellant does not present separate substantive argument for any of the dependent claims. Accordingly, we also sustain the Examiner’s rejection of dependent claims 2—11 and 13—23 for the same reasons as discussed above. DECISION We affirm the Examiner’s decision to reject claims 1—24 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). See 37 C.F.R. § 41.50(f).
