DROESCH, NORMAN H. BEAMER, and JOYCE CRAIG, Administrative Patent Judges. CRAIG, Administrative Patent Judge. DECISION ON APPEAL Appellant appeals under 35 U.S.C. § 134(a) from the Examiner’s Non-Final Rejection of claims 13, 15—17, 19, 22—30, and 32^40, which constitute of all of the claims pending in this application. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. 1 According to Appellant, the real party in interest is STMicroelectronics (Research & Development) Limited. App. Br. 2. Appeal 2016-000889 Application 13/241,976 INVENTION Appellant’s application relates to a control device using an array of single photon avalanche diodes (“SPAD”) and related methods. Abstract. Claim 13 is illustrative of the appealed subject matter and reads as follows 13. A control device for controlling an associated electronic device, the control device comprising: a proximity detector comprising an array of single photon avalanche diodes (SPAD); an input surface configured to receive control input from an object adjacent said input surface, the control input being for the associated electronic device; an illumination source configured to generate illumination to be reflected by the object to said array of SPADs; said proximity detector configured to measure movement of the object; and a controller coupled to said proximity detector and configured to adjust a first operation parameter based upon movement of the object in first and second dimensions, calculate a phase change between transmitted illumination and the illumination received following reflection from the object, determine a range of the object based upon operating said illumination source with a plurality of different modulation frequencies, adjust a second operation parameter based upon movement of the object at different positions in a third dimension using the phase change, the first operation parameter being different than the second operation parameter, and control the electronic device based upon the first and second operation parameters. 2 Appeal 2016-000889 Application 13/241,976 REJECTIONS Claims 13, 15—17, 19, 22—24, 26—30, 32, 33, and 35—40 stand rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Han (US 2006/0086896 Al; published Apr. 27, 2006), Niclass et al. (US 2006/0202129 Al; published Sept. 14, 2006) (“Niclass-1”), Hotelling et al. (US 2008/0297487 Al; published Dec. 4, 2008) (“Hotelling”), Alameh et al. (US 2010/0295772 Al; published Nov. 25, 2010 ) (“Alameh”), and Niclass (US 2007/0182949 Al; published Aug. 9, 2007)(“Niclass-2”). Claim 25 and 34 stand rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of Han, Niclass-1, Hotelling, Alameh, Niclass-2, and Homma et al. (US 2010/0156830 Al; published June 24, 2010) (“Homma”). ANALYSIS We have reviewed the Examiner’s rejections in light of Appellant’s contentions that the Examiner has erred. We disagree with Appellant’s contentions. Except as noted below, we adopt as our own: (1) the findings and reasons set forth by the Examiner in the action from which this appeal is taken and (2) the reasons set forth by the Examiner in the Examiner’s Answer in response to Appellant’s Appeal Brief. We concur with the conclusions reached by the Examiner. We highlight the following additional points. In rejecting claim 13, the Examiner found that Han teaches or suggests all of the recited limitations, except: (i) the light sensors are of SPADs, for which the Examiner relied onNiclass-1 (Non-Final Act. 5—6 (citing Niclass-11 5)); 3 Appeal 2016-000889 Application 13/241,976 (ii) “a controller coupled to said proximity detector and configured to adjust a first operation parameter based upon movement of the object in first and second dimensions,” “adjust a second operation parameter based upon movement of the object at a different position in a third dimension using the phase change, the first operation being different than the second operation parameter,” and “control the electronic device based upon the first and second operation parameters,” for which the Examiner relied on Hotelling (id. at 6—7 (citing Hotelling Fig. 5a, 10, 26, 44)); (iii) “adjust a second operation parameter based upon movement of the object at a different position in a third dimension,” for which the Examiner relied on Alameh (id. at 7—8 (citing Alameh | 111)); and (iv) a controller configured to “calculate a phase change between transmitted illumination and the illumination received following reflection from the object,” “determine a range of the object based upon operating said illumination source with a plurality of different modulation frequencies,” and “adjust a second operation parameter based upon movement of the object at a different positions in a third dimension using the phase change,” for which the Examiner relied on Niclass-2 (id. 8—9 (citing Niclass-2 ]f]f 15— 17, 24, 78, 86)). Rejection of Claims 13, 15—17, 19, 22—24, 26—30, 32, 33, and 35—40 under 35 U.S.C. § 103(a) Appellant contends the cited portions of Niclass-2 do not disclose determining a range of the object based upon operating the illumination source with a plurality of different modulation frequencies, as claim 13 requires. App. Br. 9. Appellant argues that Niclass-2 teaches the optical source operating with a continuous modulation and, although Niclass-2 uses 4 Appeal 2016-000889 Application 13/241,976 changes in frequency for improved resolution, it does not use them in the determination of range. Id. at 9-10 (citing Niclass-2 || 23, 47, 78). Appellant’s arguments do not persuade us of Examiner error. Appellant attacks Niclass-2 individually even though the Examiner relies on the combination of Han, Niclass-1, and Niclass-2 as teaching or suggesting the disputed features. Non-Final Act. 3—9; Ans. 3^4; In reMouttet, 686 F.3d 1322, 1332 (Fed. Cir. 2012) (citing In re Keller, 642 F.2d 413, 425 (CCPA 1981)) (“The test for obviousness is what the combined teachings of the references would have suggested to those having ordinary skill in the art.”). Moreover, the Examiner found that Han teaches a solid-state image sensor based on avalanche photodiodes that measures the distance of objects in addition to their intensity. Ans. 4 (citing Han 12). Appellant presents insufficient persuasive explanation or objective evidence to rebut the Examiner’s findings. Appellant next contends Niclass-2 teaches away from the Examiner’s proposed modification of Han with the teachings of Niclass-2. App. Br. 10. In support of that contention, Appellant relies on the disclosure in Niclass-2 that “[cjontinuous modulation offers the advantage of using off-the-shelf and therefore low-cost components in the illumination subsystem.” Id. (citing Niclass-2 H 23-24.) We are not persuaded that Niclass-2 teaches away from the Examiner’s proposed modification because Appellant has not identified where Niclass-2 actually criticizes, discredits, or otherwise discourages the use of multifrequency light sources. See In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). 5 Appeal 2016-000889 Application 13/241,976 Appellant further contends the Examiner’s proffered rationale for combining the teachings of Han and Niclass-2 “appears nonsensical to the disclosure of Han” and “is tantamount to a conclusory statement and cannot support a proper conclusion of obviousness.” App. Br. 11. We disagree. We specifically find that the Examiner has articulated (see Ans. 3—8) how the claimed features are met by the reference teachings with some rational underpinning to combine Niclass-2’s teachings with those of Han. See KSR Inti Co. v. Teleflex, Inc., 550 U.S. 398, 418 (2007). Moreover, “[t]he combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.” See KSR, 550 U.S. at 416. The Examiner’s proposed combination, in which Han’s red diode detector is replaced with the SPAD taught in Niclass-1 and Niclass-2 (see Ans. 6), is based on the predictable use of prior art elements according to their established functions and, thus, would have been obvious to one of ordinary skill in the art. See id. at 417. Appellant further contends the proposed modification of Han with the teachings of Niclass-2 renders Han “unsatisfactory for its intended purpose.” App. Br. 11. Appellant argues that an artisan of ordinary skill would recognize that modifying Han with the SPAD teachings of Niclass-2, “which by definition require reverse biasing the diode past the breakdown voltage, would likely destroy the LEDs of Han.” Id. Appellant’s arguments do not persuade us of Examiner error. We agree with the Examiner (Ans. 6) that it would have been within the skill of an ordinarily-skilled artisan to modify the detector of Han with the known technique of using SPADs, as suggested by Niclass-2. See KSR, 550 U.S. at 417) (“[l]f a technique has been used to improve one device, and a person of 6 Appeal 2016-000889 Application 13/241,976 ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill” (citations omitted)). Appellant has not persuaded us that combining the respective familiar elements of the cited references in the manner proffered by the Examiner would have been “uniquely challenging or difficult for one of ordinary skill in the art” at the time of Appellant’s invention. Leapfrog Enters., Inc. v. Fisher-Price, Inc., 485 F.3d 1157, 1162 (Fed. Cir. 2007) (citing KSR, 550 U.S. at 418). Appellant also contends the Examiner’s rationale for combining Han and Hotelling is improper because “the addition of multi-dimensional touchless gestures to a touch input device of Han would likely frustrate and confuse the user.” App. Br. 12. Appellant further contends the Examiner’s rationale for combining Han and Alameh is improper because it “is insufficient and amounts to no more than a cursory statement of obviousness.” Id. Appellant also contends the Examiner’s rationale for combining Han and Niclass-2 is improper because it is “insufficient and amounts to no more than a cursory statement of obviousness.” Id. Appellant’s arguments are unpersuasive. In each instance, the Examiner has articulated some basis with rational underpinning to combine the references. See Ans. 3—8. Appellant makes no persuasive substantive arguments with regard to any of three disputed combinations. See App. Br. 12. For these reasons, we are not persuaded that the Examiner erred in finding that the combination of Han, Niclass-1, Hotelling, Alameh, and Niclass-2 teaches or suggests the limitations of claim 13. 7 Appeal 2016-000889 Application 13/241,976 Accordingly, we sustain the 35 U.S.C. § 103(a) rejection of independent claim 13, as well as the 35 U.S.C. § 103(a) rejection of independent claims 26 and 35, which Appellant argues are patentable for similar reasons. App. Br. 13. We also sustain the Examiner’s rejection of dependent claims 15—17, 19, 22—24, 27—30, 32, 33, and 36-40, for which Appellant makes no additional arguments. Id. Rejection of Claims 25 and 34 under 35 U.S.C. § 103(a) Claim 25 depends from claim 13 and recites the further limitation “wherein said proximity detector comprises an elongate slide proximity detector.” App. Br. 18. Claim 34, dependent from claim 26, recites identical limitations as claim 25. See id. at 20. The Examiner relied on Homma as teaching an elongate slide proximity detector. Non-Final Act. 24 (citing Homma Fig. 1, element 101a). Appellant contends the Examiner erred in combining the teachings of Homma with those of Han because the Examiner’s “generic rationale to combine is largely identical to the rationale to combine Han and Hotelling et al., Han and Alameh et al., and Han and Niclass.” App. Br. 13. Appellant’s arguments are unpersuasive of Examiner error. The Examiner articulated some basis with rational underpinning to combine the references. Ans. 8. In addition, the Examiner explained that modifying Han with the cited teachings of Homma would “make the device more versatile and convenient for the user as it is able to perform more function[s] . . . .” Id. Appellant makes no persuasive substantive arguments with regard to the disputed combinations. See App. Br. 13. 8 Appeal 2016-000889 Application 13/241,976 Appellant also contends that modifying the Han with an elongate slide proximity detector would “substantially impair” the display purpose of Han’s array of LEDs. App. Br. 14. We are not persuaded. The Examiner found that “Han teaches the principle of operation of the device can also be a touch sensing device as recited in paragraph 18 of Han,” and modifying Han with Homma’s elongate slide proximity detector would not impair the display purpose of Han’s array of LEDs because “Han’s array of LEDs can be used for touch sensing purpose only, or additional strips of LED as taught by Han can be used for elongate slide proximity detector only.” Ans. 9. Appellant presents no persuasive explanation or evidence to rebut the Examiner’s findings. Thus, we are not persuaded the Examiner erred in finding that the combination of Han, Niclass-1, Hotelling, Alameh, Niclass-2, and Homma teaches or suggests the limitations of claim 25. Accordingly, we sustain the Examiner’s 35 U.S.C. § 103(a) rejection of claim 25, and of claim 34, for which Appellant makes no additional arguments. See App. Br. 13—14. DECISION We affirm the decision of the Examiner rejecting claims 13, 15—17, 19, 22—30, and 32^40. 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
