“measurement value, as Jover teaches.” Id. (citing Ex. 1005 ¶¶ 39–40; Ex. 1003 ¶¶ 115–30). Among other reasons, Petitioner contends that a POSITA would have been motivated to combine “to improve the accuracy and reliability of the beam failure determination.” Id. at 37 (citing Ex. 1003 ¶¶ 115–30). Petitioner further contends that a POSITA would have had a reasonable expectation of success because “it would have been straightforward for a POSITA to implement Jover’s triggering condition in Xia’s method.” Id. at 38 (citing Ex. 1003 ¶¶ 115–30). After considering Patent Owner’s arguments, which we address below, we agree with Petitioner at this stage that the combination of Xia and Jover renders obvious limitation [1e]. Patent Owner first argues that Jover “does not cure the deficiencies of Xia because Jover’s threshold condition for an increase in BER is not used for triggering a transmission of the first and second radio signal.” Prelim. Resp. 20. Just like Xia, Patent Owner contends, Jover discloses no “causality between the threshold being exceeded and transmitting the first and second radio signal.” Id. at 21. This argument does not undermine Petitioner’s showing at this stage because Petitioner relies on Xia, not Jover, for the claimed “triggering the transmission,” or “causality,” as Patent Owner calls it. See Pet. 36–38. That is, Petitioner relies on Jover for the triggering condition and on Xia for the actual triggering. See id. Patent Owner’s argument attacking the references individually is unpersuasive. See In re Merck & Co., Inc., 800 F.2d 1091, 1097 (Fed. Cir. 1986) (“Non-obviousness cannot be established by attacking references individually where the rejection is based upon the teachings of a combination of refences.”). Patent Owner next contends that one of ordinary skill in the art would not have combined Xia and Jover “since Jover is directed to the opposite objective of the ’113 Patent or Xia.” Prelim. Resp. 21. That is, Patent Owner asserts, Jover teaches away from the disclosed methods. Id. at 22. Patent Owner explains, “Jover provides no attempt to improve the beam strength, but rather ignores it through beam sweeping or nullif[ies] it, in contrast to the purpose of the ’113 Patent.” Id. at 22–23.

Moreover, we are persuaded that a person of ordinary skill in the art at the critical time would have had reason to apply the teachings of Suzuki to Peterka. Specifically, we credit the testimony of Mr. Wechselberger, who testifies that (1) Peterka and Suzuki are in the same field of art and (2) both references disclose “periodically” changing keys that protect distributed content. Ex. 1003 ¶ 154 (citing Ex. 1006 ¶¶ 3, 12; Ex. 1005 ¶¶ 82, 110). Mr. Wechselberger explains that an ordinarily skilled artisan would have recognized the importance of identifiers “to differentiate amongst keys, and that providing unique values (such as key numbers) to keys would ensure that the system does not confuse keys.” Id. ¶ 153. According to Mr. Wechselberger, an ordinarily skilled artisan “would have had reasons to implement Peterka’s client in view of Suzuki to acquire and use ‘key information’ about a next key—its ‘remaining validity time’ and ‘key number’—at a set time before the expiration of the current key, and thereby facilitate timely key acquisition and use.” Id. ¶ 155 (citing Ex. 1006 ¶¶ 76–77, 80–81, 43–48) (emphasis added). At this stage of the proceeding, and crediting the testimony of Mr. Wechselberger, we are persuaded that the combined teachings of Peterka and Suzuki would have allowed a person of ordinary skill in the art “to ‘eliminat[e] the confirmation delay’ during key changes, and realize Peterka’s embodiment where “each client keeps track of the keys and their expiration times and actively requests new keys before the current keys expire so as to avoid service interruptions.” See Ex. 1006 ¶ 11; Ex. 1005 ¶ 105.” slip op. at 30

“The standard for instituting an inter partes review is set forth in 35 U.S.C. § 314(a), which provides that an inter partes review may not be instituted unless the information presented in the Petition and any preliminary response shows that “there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” For the reasons explained below, we determine that Petitioner has established a reasonable likelihood that it would prevail with respect to at least one challenged claim. Accordingly, we institute an inter partes review as to the challenged claims and grounds raised in the Petition.” slip op. at 2

“Petitioner’s expert contends that person of ordinary skill in the art (POSITA): [W]ould have had a bachelor’s degree in computer science, computer engineering, electrical engineering, or a related field, and 2–3 years of practical engineering experience relating to information security systems that employ cryptographic keys to encrypt/decrypt digital data. Additional education could substitute for professional experience, or significant experience in the field could substitute for formal education. Ex. 1003 ¶ 41. Patent Owner does not dispute the Petitioner’s proposal at this time. Prelim. Resp. 8. Based on a review of the record, we adopt Petitioner’s proposed level of ordinary skill in the art because it is consistent with the evidence of record, including the asserted prior art and ’178 patent specification.

“the special case of key changes requested for security reasons outside of any fixed duration lifespan. Ex. 1001, 10:40–42. Considering, as we must, the disclosure of the ’178 patent as a whole, the scope of the disclosure is directed broadly to key rotation in general, whether due to scheduled key expiration times or otherwise. Id. at code (57), Fig. 3, 1:63–65, 2:23–25, 3:26–28, 9:47–49; see also Superguide Corp. v. DirecTV Enter., Inc., 358 F.3d 870, 875 (Fed.

“combine the teachings of Peterka, Suzuki, and Bocharov. Pet. 51–53, 57– 59, 66–67. Petitioner argues that Suzuki, like Peterka, discloses clients acquiring keys for multiple media segments, and provides implementation details, not disclosed in Peterka, regarding how to keep track of keys and their expiration times, and how to determine when a new key is required. Pet. 51–52 (citing Ex. 1003 ¶¶ 161–164). Petitioner argues that, given that Peterka and Suzuki are in the same field of art, one of ordinary skill would have been motivated to use the specific details of Suzuki in implementing the disclosure of Peterka. Id. at 53, 66 (citing Ex. 1003 ¶¶ 165–167, 202–204). Petitioner also argues that Peterka indicates that video content can be streamed using various protocols and bit rates, but does not provide implementation details. Pet. 57–59, 66–67 (citing Ex. 1003 ¶¶ 179–184, 204). However, argues Petitioner, one of ordinary skill in the art would have had reason to use the manifest files of Bocharov to provide the necessary information to handle different protocols and bit rates. Id. Petitioner argues that one of ordinary skill in the art would have been so motivated because implementing Peterka’s system to use Bocharov’s manifests would have provided an effective solution for allowing clients to switch between multiple versions of a media program having different encodings/qualities/bit rates. Id. Patent Owner does not specifically address the merits of combining Peterka, Suzuki, and Bocharov. See generally Prelim. Resp. Nonetheless the burden remains on Petitioner to demonstrate unpatentability. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). For purposes of this Decision, we determine that Petitioner has provided sufficiently articulated reasoning with rational underpinnings for the proffered combined teachings of Peterka, Suzuki, and Bocharov.” slip op. at 29

“Petitioner contends that one motivation for combining would have been that Marcus ’904 includes additional disclosure of targeting media programming to specific users, which would lead to better customization of media programming by Cristofalo. Pet. 38 (citing Ex. 1002 ¶ 122). This assertion is vague and unexplained. Petitioner also asserts that Marcus ’904 provides “additional implementation details” on how final media programming is generated and formatted for display. Id. at 38–39 (citing Ex. 1002 ¶ 123). We fail to see, at this stage, how merely disclosing additional details would motivate a skilled artisan to combine references. If we were to agree with a proposed combination merely because one reference includes details another does not, this could “swallow all of patent law.” Cf. Alice Corp. Pty. Ltd. v. CLS Bank Int’l, 573 U.S. 208, 217 (2014) (addressing patent eligibility). Finally, Petitioner contends that combining Marcus ’904’s advertising sources would unlock new revenue sources for Cristofalo. Pet. 39 (citing Ex. 1002 ¶ 124). Patent Owner argues that this rationale appears to be superfluous, since Cristofalo already discloses targeting advertising to users. Prelim. Resp. 26 (“Cristofalo’s receiving system ‘already’ assembles the programming with advertisements.”); see Pet. 38 (referring to Cristofalo’s “targeted advertising”). We tend to agree at this stage. Thus, we question Petitioner’s rationale to combine Cristofalo with Marcus ’904.” slip op. at 16

“Patent Owner attacks Petitioner’s “post-hoc rationalization for its proposed modification,” namely “more efficient processing or ‘simplifying processing and communications.’” Prelim. Resp. 26 (citing Pet. 18–19).14 Patent Owner asserts, in part, that Whitehead’s design already permits the “real time or near-real time” assembly of a custom media channel, so “it would be superfluous to include the same information again in the custom channel request.” Id. at 27–28 (citing, e.g., Ex. 1003, 4:40–44, 8:45–51, 11:45–49). At this stage, we tend to agree with Patent Owner. Petitioner acknowledges that “[m]ixing server 130 creates custom media channel 170 in real time or near real-time” yet asserts a POSITA would have modified Whitehead to speed up this process. See Pet. 18. If Whitehead already processes in real time or near real time, it is unclear why a skilled artisan would have sped up that process. Thus, Petitioner’s rationale does appear to be superfluous and hindsight-based at this stage.” slip op. at 17
