    “350 receiving a request for a listing of “services” from a gateway device and provisioning one or more tunnel servers has not been shown to teach generating “a list of available servers.” There is no persuasive evidence to support Petitioner’s assertion. Petitioner relies on unsupported argument because, at best, Hankins discloses gateway devices 311 and 321, each of which is located in different logical broadcast domains, requesting services from one another. Ex. 1005, 12:9–16. This particular disclosure, however, does not appear to implicate the functionality of Hankins’s controller 350, much less result in controller 350 generating a list of available tunnel servers that would allow gateway devices 311 and 312 to exchange a listing of “services” therebetween. Petitioner’s reliance on Hankins’s controller 350 provisioning additional tunnel servers both to improve performance and without human intervention fares no better. Ex. 1005, 25:45–55. There is no indication in Hankins that this provisioning performed by controller 350 is done in response to receiving a request for a list of available tunnel servers from either gateway device 311 or 312.” slip op. at 20

More specifically, Petitioner argues, a person of ordinary skill in the art “would have had a master’s degree in computer science, computer engineering, or an equivalent, and two years of professional experience relating to network communications and resource allocations,” where “[a]dditional work experience can substitute for specific educational background, and vice versa.” Id.

Because our conclusion that Petitioner has not demonstrated that any of the challenged claims are unpatentable does not turn on the construction of either “predetermined” or “quantum,” there is no need for us to construe those terms.

The specification supports this understanding. “When a receiver is actively receiving a desired signal, each block in the signal path has at its input the desired signal as well as noise and possibly interfering signals.” Ex. 1001, 5:20–22; see also id. at 5:31–33 (“FIGS. 2A and 2B illustrate examples of desired signals, interferers, and noise that may be received by one of the various circuits in a” slip op. at 21

    “We agree with Patent Owner that Rauhala does not state that the signal strengths are measured simultaneously or at the same time. Indeed, as discussed above, Rauhala indicates unequivocally in the same paragraph the opposite—that detector DET provides to control unit 42 “an indication about either the receive channel signal strength RSS or the strength of any signal on the reception band.” Ex. 1004 ¶ 17. Rauhala describes that “control unit 42 provides two one-bit control signals cA and cM” based on indications received from detector DET. Id. Importantly, Rauhala indicates that “at the same time as” describes how the control unit 42 uses the received inputs RSS and RSSn shown in Figure 4, which are described earlier in paragraph 17 as indications of either RSS or RSSn from detector DET.

The burden remains on Petitioner to demonstrate by a preponderance of the evidence that Rauhala discloses the disputed limitations as arranged or combined in the claim. Petitioner does not persuasively reconcile these “either/or” statements regarding the functioning of detector DET with the “at the same time as” statements regarding control signals output by control unit 42 in paragraph 17. We do not find persuasive Petitioner counsel’s position expressed at the hearing that Rauhala’s “either/or” statements are “simply an imprecise description” (Tr. 16:22–24).

Petitioner does not identify any testimony from Dr. Lieberman that supports Petitioner’s Reply position that Lebrun’s group-surfing server “forwards” the session-creation message to the group-surfing session participants, nor are we aware of any such testimony. See, e.g., Ex. 1003 ¶ 149 (The group-surfing server “responds to the group session request ‘by (1) creating a group-surfing session, and (2) informing the participants [web clients] in the group-surfing session.”); see generally Ex. 1034.

Similarly, claim 1 requires the invitee device to retrieve data from the website server in response to receiving “the information related to the shared web browsing interaction from the synchronization server” (limitation [1f.iii]). For the reasons discussed above, Petitioner has not shown by a preponderance of the evidence its combination of Lebrun and Wang does so.

    “time of the ’726 patent would likely understand the relationship between power and energy. We also agree that there is a relationship between power and energy, and that it is possible to derive information about one from the other. See Ex. 1012, 18:14–25:8; Ex. 2001, 25:10–27:14; Ex. 2005, 238. Based on the evidence of record, we do not agree, however, that power and energy “are essentially equivalent and can be used interchangeably” as asserted in the Petition. See id.; see Pet. 36 (citing Ex. 1009 ¶¶ 174–177). Nor do we agree one of ordinary skill in the art would have understood that the Gupta energy threshold is the same as the power level threshold disclosed in Li. See Ex. 1012, 18:14–25; Ex. 2001, 25:10–27:14; Ex. 2005, 238. Petitioner’s reliance on Dr. Williams’s testimony regarding Gupta’s disclosure that “[a] minimum energy threshold may be programmed to [the cadence tone’s] required power level for a valid signal on a line” is equally unpersuasive. Ex. 1009 ¶ 181 (citing Ex. 1004, 6:41–44). We are unpersuaded because neither Petitioner nor Dr. Williams explains sufficiently how Gupta’s minimum energy threshold relates to a required power level or how it relates to Li’s power estimator and the purpose of Li’s power estimators. Given the lack of equivalence between power and energy, we find Petitioner fails to present sufficient evidence explaining why a person of ordinary skill in the art would have switched from detecting a power threshold, such as that described in Li and required by the challenged claims, to detecting an energy threshold as disclosed in McNitt and Gupta.

Dr. Franzon’s testimony as to the level of 12 ordinary skill is based on “the type of problems encountered in the art, prior art solutions to those problems, the rapidity with which innovations are made, the sophistication of the technology, and the educational level of active workers in the field.” Ex. 1002 ¶ 53.

    “As noted in our claim construction section, above and as referenced in our Final Written Decision in IPR2016-00386, a preponderance of the evidence establishes that, in the context of semiconductor substrates, mere thinning is not the same as flexibility—being able to bend without breaking. 20 Although Petitioner presents arguments attempting to demonstrate thinning, there are no arguments that this thinning necessarily results in flexibility. Thus, we determine that Petitioner has not met its burden to demonstrate that the required “substantial flexibility.” This reason alone sufficiently supports our conclusion. However, we also conclude, as set forth below that for a second, independent reason, Petitioner has not established that the challenged claims are unpatentable. Petitioner has not sufficiently established that one of ordinary skill would have substituted the dielectric material of Leedy ’695 for the various layers proposed for substitution in Hsu.
