HAGY, DAVID J. CUTITTA II, and SCOTT RAEVSKY, Administrative Patent Judges. CUTITTA, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Pursuant to 35 U.S.C. § 134(a), Appellant1 appeals from the Examiner’s decision to reject claims 1–20, all of the claims under consideration. We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM. 1 “Appellant” refers to “applicant” as defined in 37 C.F.R. § 1.42(a). Appellant identifies the real party in interest as Symbol Technologies, LLC. Appeal Brief filed May 24, 2019 (“Appeal Br.”) 3. Appeal 2020-000263 Application 15/000,660 2 CLAIMED SUBJECT MATTER Summary Appellant’s claimed subject matter relates to using a pair of cameras to capture full-frame stereo image pairs and “transmitting full-frame images and sub-sampled images over a communication interface.” Spec. ¶ 3.2 According to Appellant, due to bandwidth limitations of USB, “bandwidth of interface 111 is limited such that a frame rate of full-frame images from cameras 105 over interface 111 is not large enough to provide a live-image preview at a host device.” Id. ¶ 38. To reduce the required bandwidth, the invention scales a first subset of pairs of the full-frame images to produce a set of pairs of sub-scaled images. Id. ¶ 33. The scaled subset of pairs allows a live-image preview to be provided to a host device. Id. ¶ 38. Exemplary Claims Claims 1, 11, and 20 are independent. Claims 1, 2, 3, 6, 7, and 10, reproduced below with certain limitations at issue italicized, exemplify the claimed subject matter: 1. A device comprising: a first camera device and a second camera device; one or more camera communication interfaces in communication with the first camera device and the second camera device; an output communication interface; and, an image streaming processor configured to: 2 In addition to the Appeal Brief noted above, we refer to: (1) the originally filed Specification filed January 19, 2016 (“Spec.”); (2) the Final Office Action mailed July 27, 2018 (“Final Act.”); and (3) the Examiner’s Answer mailed August 16, 2019 (“Ans.”). Appeal 2020-000263 Application 15/000,660 3 receive full-frame images from each of the first camera device and the second camera device using the one or more camera communication interfaces; synchronize the full-frame images in pairs; scale a first subset of the pairs of the full-frame images to produce a set of pairs of sub-scaled images; and, transmit the set of pairs of sub-scaled images and a second subset of the pairs of the full-frame images over the output communication interface, the second subset of the pairs of the full-frame images remaining unscaled. 2. The device of claim 1, further comprising a memory and the image streaming processor is further configured to store at least the second subset of the pairs of the full-frame images in the memory prior to transmitting the set of pairs of sub-scaled images and the second subset of the pairs of the full-frame images over the output communication interface. 3 The device of claim 1, further comprising an image converter configured to convert the set of pairs of sub- scaled images and the second subset of the pairs of the full- frame images to an output data format prior to transmitting the set of pairs of sub-scaled images and the second subset of the pairs of the full-frame images over the output communication interface. 6. The device of claim 1, wherein the image streaming processor is further configured to scale the first subset of the pairs of the full-frame images to produce the set of pairs of sub-scaled images by one or more of reducing a size and reducing a resolution of the first subset of the pairs of the full-frame images. 7. The device of claim 1, wherein the image streaming processor is further configured to transmit the set of pairs of sub-scaled images and the second subset of the pairs of the full-frame images over the output communication interface by interleaving the pairs of sub-scaled images and the second subset of the pairs of the full-frame images. Appeal 2020-000263 Application 15/000,660 4 10. The device of claim 1, further comprising a host device comprising: a respective communication interface, physically and communicatively mated with the output communication interface; a display device; and an image processor configured to: receive the set of pairs of sub-scaled images and the second subset of the pairs of the full-frame images over the respective communication interface, from the output communication interface; render at least a subset of the set of pairs of sub-scaled images at the display device; and, process the second subset of the pairs of the full-frame images to determine dimensions of items represented in the second subset of the pairs of the full-frame images. Appeal Br. 18–20. REFERENCES AND REJECTION The Examiner rejects claims 1–20 under 35 U.S.C. § 103 as obvious over the combined teachings of Fu et al., A Reconfigurable Real-Time Compressive-Sampling Camera for Biological Applications, PLOS ONE, vol. 6, no. 10 (2011) (“Fu”) and Kim et al. (US 2011/0181694 A1, published July 28, 2011) (“Kim”). Final Act. 2–10. OPINION We review the appealed rejection for error based upon the issues identified by Appellant and in light of Appellant’s arguments and evidence. Ex parte Frye, 94 USPQ2d 1072, 1075 (BPAI 2010) (precedential). Arguments not made are waived. See 37 C.F.R. § 41.37(c)(1)(iv) (2018). Appellant does not persuade us that the Examiner errs, and we adopt as our own the findings and reasons set forth by the Examiner to the extent Appeal 2020-000263 Application 15/000,660 5 consistent with our analysis herein. Final Act. 2–10; Ans. 10–12. We add the following primarily for emphasis. Obviousness Rejection of Claim 1 The Examiner finds Kim teaches or suggests “scale a first subset of the pairs of the full-frame images to produce a set of pairs of sub-scaled images,” as recited in claim 1. Final Act. 6 (citing Kim ¶ 256). Appellant argues that “Kim nowhere teaches or suggests scaling of any ‘subset’ of the full-frame images” because “Kim merely discusses two separate cases that operate on the entire video stream.” Appeal Br. 10 (citing Kim ¶ 256). According to Appellant, in Kim, “both left and right view frames of the entire video stream are reduced to half size of the original frame” and thus “Kim nowhere teaches or fairly suggests scaling a ‘subset’ of full-frame images.” Id. Appellant’s argument is unpersuasive of reversible Examiner error. Kim discloses an additional-view video stream having a 3D composite frame format reducing to half “the sizes of a left-view frame and a right-view frame that constitute the composite frame.” Kim ¶ 256. Even assuming, as Appellant argues, that Kim’s video ultimately scales the entire stream of frames, we find Kim still teaches scaling a subset of frames upon an initial scaling of the first pair of frames in the series and, again, when each subsequent pair of frames in the series is scaled. That is, each time Kim reduces a pair of frames in a video stream to half-size data by halving a vertical resolution, Kim teaches scaling a first subset of the pairs, as claimed, where each pair of scaled frames in Kim represents a subset of frames in the series of pairs making up the entire video stream. Appellant’s argument that Kim does not teach scaling a subset because Kim’s scaling of left and right Appeal 2020-000263 Application 15/000,660 6 view frames is of the entire video stream is not commensurate with the claim scope, because claim 1, by reciting “scal[ing] a first subset of the pairs,” does not preclude eventually scaling an entire series of frames in succession. Claim 1 further recites “transmit the set of pairs of sub-scaled images and a second subset of the pairs of the full-frame images over the output communication interface.” Appeal Br. 18. The Examiner finds, and we agree, that Kim “discloses transmitting a full size base-view video and half size additional view video at the same time during broadcasting.” Ans. 11– 12 (citing Kim ¶¶ 241, 253–256, Fig. 12); Final Act. 6. Appellant argues: As explained above, Kim either reduces both left and right view frames of the entire video stream to half size of the original frame or keeps both the right and the left view frames of the entire video stream at full size. Therefore, it also does not teach or suggest transmitting scaled and unscaled subsets of images. Appeal Br. 12. This argument relies on Appellant’s argument that “Kim nowhere teaches or suggests scaling of any ‘subset’ of the full-frame images.” Id. at 10. Because we find that argument unpersuasive, as discussed above, we find Appellant’s additional argument unpersuasive for similar reasons. Accordingly, Appellant does not persuade us of error in the Examiner’s obviousness rejection of independent claim 1. We, therefore, sustain the Examiner’s rejection of that claim, as well as the rejection of claims 4, 5, 8, 9, 11, 14, 15, 18, and 20, which Appellant does not argue separately with particularity. Appeal Br. 13–17. Appeal 2020-000263 Application 15/000,660 7 Obviousness Rejection of Claims 2 and 12 The Examiner finds the combination of Fu and Kim teaches or suggests the “image streaming processor is further configured to store at least the second subset of the pairs of the full-frame images in the memory prior to transmitting the set of pairs of sub-scaled images and the second subset of the pairs of the full-frame images over the output communication interface,” as recited in claim 2. Final Act. 7–8 (citing Fu, page 1, left column; Kim ¶¶ 241, 253–256, Fig. 12). Appellant argues that: The Office action refers to the left column on page 1 of [Fu] in rejecting claim 2. Office action page 7. However, it is submitted that [neither] the highlighted portion, nor any portion of [Fu], fairly discloses storing at least the second subset of the pairs of the full-frame images in the memory prior to transmitting both the set of pairs of sub-scaled images and the second subset of the pairs of the full-frame images. Appeal Br. 13 (emphasis omitted). The Examiner responds that “Fu is relie[d on] to teach a need for storage in the camera before images transmission. The two subset of images is disclosed and rebutted as above.” See Ans. 12 (referring to the Examiner’s reliance on Kim to teach transmitting the subsets of pairs of images). Appellant’s argument based on Fu is unpersuasive because the Examiner relies on the combined teachings of Fu and Kim, rather than Fu alone, to teach the limitation at issue. Accordingly, Appellant’s argument regarding claims 2 and 12 is not responsive to the Examiner’s findings. Appeal 2020-000263 Application 15/000,660 8 Obviousness Rejection of Claims 3 and 13 The Examiner finds the combination of Fu and Kim teaches or suggests “an image converter configured to convert the set of pairs of sub- scaled images and the second subset of the pairs of the full-frame images to an output data format prior to transmitting the . . . images over the output communication interface,” as recited in claim 3. Final Act. 7 (citing Fu, page 1, left column; Kim ¶ 150, Fig. 8). Appellant argues: As neither Kim nor [Fu] discloses or suggests transmitting the set of pairs of sub-scaled images and the second subset of the pairs of the full-frame images, neither cited reference can disclose converting the set of pairs of sub-scaled images and the second subset of the pairs of the full-frame images to an output data format prior to said transmission. Appeal Br. 14. The Examiner responds that Kim’s paragraph 150 teaches a “channel encoder [to] convert the image signal into channel signal for transmission,” and that Kim further teaches transmitting the two subsets of images, as discussed with respect to claim 1. Ans. 13. Appellant’s argument as to this limitation relies on Appellant’s argument that Kim fails to teach transmitting the images, in claim 1, which in turn relies on Appellant’s first claim 1 argument that “Kim nowhere teaches or suggests scaling of any ‘subset’ of the full-frame images.” Appeal Br. 10. Because we find both of those claim 1 arguments unpersuasive, as discussed above at pages 5–6, we find Appellant’s additional argument regarding claims 3 and 13 unpersuasive for similar reasons. Appeal 2020-000263 Application 15/000,660 9 Obviousness Rejection of Claims 6 and 16 The Examiner finds the combination of Fu and Kim teaches or suggests the “image streaming processor is further configured to scale the first subset of the pairs of the full-frame images to produce the set of pairs of sub-scaled images by one or more of reducing a size and reducing a resolution of the first subset of the pairs of the full-frame images,” as recited in claim 6. Final Act. 8 (citing Fu; Kim ¶ 254). Appellant argues that: neither Kim nor [Fu] discloses or suggests scaling the first subset of the pairs of the full-frame images to produce the set of pairs of sub-scaled images and therefore neither cited reference can disclose or suggest scaling the first subset by one or more of reducing a size and reducing a resolution of the first subset. Appeal Br. 15. This argument relies on Appellant’s argument that “Kim nowhere teaches or suggests scaling of any ‘subset’ of the full-frame images.” Id. at 10–11. Because we find that argument unpersuasive, as discussed above at pages 5–6, we find Appellant’s additional argument regarding claims 6 and 16 unpersuasive for similar reasons. Obviousness Rejection of Claims 7 and 17 The Examiner finds the combination of Fu and Kim teaches or suggests the “image streaming processor is further configured to transmit the set of pairs of sub-scaled images and the second subset of the pairs of the full-frame images over the output communication interface by interleaving the pairs of sub-scaled images and the second subset of the pairs of the full- Appeal 2020-000263 Application 15/000,660 10 frame images,” as recited in claim 7. Final Act. 8 (citing Fu; Kim ¶ 258, Table 10). Appellant argues that neither Kim nor Fu teaches an image streaming processor interleaving images as recited in claim 7, because in the claimed interleaving “images of one of either the pairs of sub-scaled images or the second subset of the pairs of the full-frame images are transmitted, followed by images of the other one of the pairs of sub-scaled images or the second subset of the pairs of the full-frame images, and so on.” Appeal Br. 15. The Examiner responds: What is claimed is “by interleaving the pairs of sub-scaled images and the second subset of the pairs of the full-frame images.” Instead Applicant argue[s]: “interleaving results in that images of one of either the pairs of sub-scaled images or the second subset of the pairs of the full-frame images are transmitted, followed by images of the other one of the pairs of sub-scaled images or the second subset of the pairs of the full- frame images, and so on.” Ans. 14–15 (citing Kim ¶¶ 261, 258, Table 10). Appellant’s argument is not commensurate with the scope of claim 7 because, as the Examiner notes (id.), the claim does not specifically recite interleaving images in a particular order. Limitations not appearing in the claim cannot be relied upon for patentability. In re Self, 671 F.2d 1344, 1348 (CCPA 1982). Accordingly, this argument is unpersuasive of reversible Examiner error, and we sustain the obviousness rejection of dependent claims 7 and 17. Appeal 2020-000263 Application 15/000,660 11 Obviousness Rejection of Claims 10 and 19 The Examiner finds the combination of Fu and Kim teaches or suggests “a host device,” as recited in claim 10. Final Act. 9. Appellant argues: [Fu] describes a camera system that adaptively concentrates available bandwidth on certain pixels while sampling the remainder of the pixels at low speed. However, [Fu] fails to disclose scaling images of any kind. [Fu] therefore further cannot disclose rendering at least a subset of the set of pairs of sub-scaled images at a display device of the host device and processing the second subset of the pairs of the full-frame images to determine dimensions of items represented in the second subset of the pairs of the full-frame images, as recited in claim 10 and as similarly recited in claim 19. Appeal Br. 16–17. The Examiner responds by finding that Fu teaches the claimed host device with components including a communication interface that receives the set of pairs of sub-scaled images. Ans. 16 (citing Fu, page 3, left column, Fig. 1). The Examiner notes that Kim is relied upon to specifically teach the receiving of scaled of subsets of pairs of images, as set forth in the rejection of claim 1. Ans. 16. Appellant’s argument based on Fu is unpersuasive because the Examiner relies on the combined teachings of Fu and Kim, rather than Fu alone, to teach the limitation at issue. Final Act. 9; Ans. 16. Accordingly, Appellant’s argument is not responsive to the Examiner’s findings and we sustain the obviousness rejection of dependent claims 10 and 19. Appeal 2020-000263 Application 15/000,660 12 CONCLUSION We affirm the Examiner’s decision to reject claims 1–20 under 35 U.S.C. § 103.
