HAMANN, and SCOTT E. BAIN, Administrative Patent Judges. HAMANN, Administrative Patent Judge. DECISION ON APPEAL Appellants file this appeal under 35 U.S.C. § 134(a) from the Examiner's Final Rejection of claims 1-28. We have jurisdiction under 35 U.S.C. § 6(b). We reverse. 1 Our decision relies upon Appellants' Appeal Brief ("App. Br.," filed Oct. 8, 2017), Reply Brief ("Reply Br.," filed Mar. 30, 2018), and Specification ("Spec.," filed Aug. 14, 2014), as well as the Examiner's Answer ("Ans.," mailed Feb. 1, 2018) and the Final Office Action ("Final Act.," mailed May 11, 2017). 2 According to Appellants, the real party in interest is Irdeto B.V. App. Br. 2. Appeal2018-004702 Application 14/378,962 THE CLAIMED INVENTION Appellants' claimed invention relates to "generating, from initial content data, output content data for provision to one or more receivers." Spec. 1. Claim 1 is illustrative of the subject matter of the appeal and is reproduced below. 1. A method, implemented by one or more computer processors, for generating, from initial content data, output content data for provision to one or more receivers, wherein the initial content data is encoded according to a coding scheme, wherein for a quantity of data encoded according to the coding scheme, the coding scheme provides a mechanism for including in the quantity of encoded data additional data such that a decoder for the coding scheme, upon decoding the quantity of encoded data, does not use the additional data to generate decoded data, the method comprising: selecting one or more portions of the initial content data; for each selected portion, generating a data construct that comprises a plurality of data structures, each data structure comprising data, including a version of the selected portion, that is encrypted using a corresponding encryption process different from each encryption process used to encrypt data in the other data structures, wherein the data construct is arranged such that using a decryption process that corresponds to the encryption process for one data structure on the encrypted data in each data structure in the data construct produces a quantity of data encoded according to the coding scheme that uses the mechanism so that a decoder for the coding scheme would not use any data structure in the data construct other than said one data structure; and using the generated data constructs in the initial content data instead of their corresponding selected portions to form the output content data. 2 Appeal2018-004702 Application 14/378,962 REJECTIONS ON APPEAL (1) The Examiner rejected claims 1-9, 11-24, and 26-28 under 35 U.S.C. § 102 as being anticipated by Wasilewski (US 2005/0152548 Al; published July 14, 2005). Final Act. 6-17. (2) The Examiner rejected claims 10 and 25 under 35 U.S.C. § 103 as being unpatentable over the combination of Wasilewski and Candelore (US 2005/0169473 Al; published Aug. 4, 2005). Final Act. 17-19. ISSUE The dispositive issue for this appeal is whether Wasilewski discloses that "the data construct is arranged [to] ... us [ e] a decryption process that corresponds to the encryption process for one data structure on the encrypted data in each data structure in the data construct." ANALYSIS We have reviewed the Examiner's rejections in light of Appellants' contentions that the Examiner errs. We find Appellants' arguments discussed herein3 persuasive. Appellants argue that Wasilewski fails to disclose that "the data construct is arranged [to] ... us [ e] a decryption process that corresponds to the encryption process for one data structure on the encrypted data in each data structure in the data construct," as recited in independent claims 1, 14, and 16. App. Br. 10-12; Reply Br. 5---6. In other words, Wasilewski fails to 3 Because we agree with at least one of the dispositive arguments advanced by Appellants, we need not reach the merits of Appellants' other arguments. 3 Appeal2018-004702 Application 14/378,962 disclose using the decryption process on both data structures, including for the data structure having encrypted data that uses a different encryption process, according to Appellants. Id. Appellants argue that Wasilewski instead discloses applying the decryption process to just the data structure that employs the corresponding encryption process (i.e., the same coding scheme) and skipping the other data structure that employs a different encryption process. See Reply Br. 6-7 (citing Wasilewski ,r,r 34--37); App. Br. 10-11 (citing Wasilewski Fig. 5). The Examiner finds that Wasilewski discloses the disputed limitation. See Ans. 6-7, 12. More specifically, the Examiner finds that the disputed limitation means "encrypting segmented data separately by different associated key for each version and decrypting correct one by the receiver with corresponding decryption key and method." Ans. 12. Based on this interpretation, the Examiner finds that Wasilewski teaches "that incoming packets are separated in 2 streams for different encryption methods, and appropriate subscriber decrypts the packet with matching decryption key separately. This reference uses separate encryption/ decryption method for different type of set top boxes." Id. ( citing Wasilewski Fig. 5); see also id. at 11 ( citing Wasilewski ,r,r 3-5). Based on the evidence of record, we are constrained to agree with Appellants that the Examiner errs in finding that the cited portions of Wasilewski disclose the disputed limitation. First, we disagree with the Examiner's interpretation of the disputed limitation. "Although the [US]PTO must give claims their broadest reasonable interpretation, this interpretation must be consistent with the one that those skilled in the art would reach." In re Cortright, 165 F.3d 1353, 1358 (Fed. Cir. 1999) (citing 4 Appeal2018-004702 Application 14/378,962 In re Morris, 127 F.3d 1048, 1054 (Fed. Cir. 1997)). Simply put, the Examiner's interpretation is not consistent with the one that those skilled in the art would reach because the unambiguous claim language recites "using a decryption process that corresponds to the encryption process for one data structure on the encrypted data in each data structure in the data construct." App. Br. 15 ( emphasis added); see also Texas Instruments Inc. v. US. Int 'l Trade Comm 'n, 988 F.2d 1165, 1171 (Fed. Cir. 1993) (quoting Autogiro Co. v. United States, 384 F.2d 391,396 (1967)) ("Courts can neither broaden nor narrow claims to give the patentee something different than what he has set forth."). In applying Wasilewski's disclosure to the plain meaning of the disputed limitation ( as Appellants do), we agree with Appellants that Wasilewski discloses applying the decryption process to just one data structure (i.e., the one that employs the same coding scheme) and skipping the other data structure that employs a different encryption process. See Wasilewski ,r,r 34--37, Fig. 5. In other words, we find that Wasilewski fails to disclose using the decryption process on the encrypted data in each data structure in the data construct. Id. CONCLUSION Based on our reasoning above, we do not sustain the Examiner's § 102 rejection of independent claims 1, 14, and 16, as well as claims 2-9, 11-13, 15, 17-24, and 26-28, as they depend from one of these independent claims. As to the Examiner's § 103 rejection of claims 10 and 25, the Examiner relies on the above discussed findings from Wasilewski regarding 5 Appeal2018-004702 Application 14/378,962 the disputed limitation. Accordingly, we also do not sustain the Examiner's § 103 rejection of claims 10 and 25. DECISION We reverse the Examiner's decision rejecting claims 1-28.
