  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Patent Owner does not provide a different assessment of the level of ordinary skill, but Dr. Przybylski states that an individual with the level of experience identified by Petitioner “would have less knowledge and familiarity” than presumed by Petitioner’s definition. Ex. 2003 ¶ 46. Dr. Przybylski, however, provides no further discussion explaining this apparent disagreement with Petitioner, nor does he set forth what level of knowledge and familiarity a person of ordinary skill in the art would have had. Based on the complete trial record, we determine that Petitioner’s proposed skill level is consistent with the level of ordinary skill evidenced by the ’314 patent and the asserted prior art, and we adopt that skill level with the exception of the phrases “at least,” which introduce vagueness as to the amount of experience.” slip op. at 6

    “We disagree with Petitioner’s interpretation. Taking Petitioner’s point that “‘specified data rate’ means only that the data rate is specified in some way” (Pet. Reply 4), we do not see how, once the rate is specified, claim 1’s later recitations of “the specified data rate” could refer to any other rate, as Petitioner’s arguments suggest. Petitioner argues that “it is clear that the ‘specified data rate’ that provides antecedent basis for later recitations of that term is merely the data rate specified for ‘communicat[ing] data’ between the ‘memory module’ and the external ‘memory controller of the computer (alteration by Petitioner). We agree with this statement, and later recitations of “the specified data rate,” therefore, refer to the data rate that is so specified. Petitioner provides no persuasive argument to support its position that later recitations of “the specified data rate” could be satisfied by data rates that are not the “specified data rate.”” slip op. at 7

    “PO Resp. 19; see also Ex. 2003 ¶¶ 68–72 (Dr. Przybylski’s testimony explaining this annotated figure). Halbert’s Figure 5 is a timing diagram for two consecutive read operations (Ex. 1005 ¶¶ 16, 37), and Patent Owner includes annotations to show each of ranks 140 and 142 outputting data onto their respective data busses at half the rate that data are output from data interface circuit 120 on the DQ data line. In particular, Halbert explains that each of ranks 140 and 142 is “capable of performing m-bit-wide data transfers.” Ex. 1005 ¶ 30. On a read command, rank 140 sends m-bit-wide data to bi-directional data register 126 on line RDQ0 at the same time that rank 142 sends m-bit-wide data to bi-directional data register 128 on line RDQ1, as shown in Figure 5 between T7n and T8n. Ex. 1005 ¶¶ 31–32, 39. Halbert discloses that register 126 or from register 128 to output to buffer 122, which are then output on line DQ. Ex. 1005 ¶ 33. Halbert explains that “[d]ata is serialized from the data registers onto the memory data bus by reading 2m bits into the data registers during one memory device read cycle, and then driving these bits, m at a time, through MUX 124.” Ex. 1005 ¶ 33. As shown in Halbert’s Figure 5, over one clock cycle (T7n–T8n), each of ranks 140 and 142 outputs one piece of m-bit-wide data, and over one clock cycle (T8–T9), those two pieces of m-bit-wide data are output on line DQ to the system memory data bus. Halbert explains that the second read operation proceeds in the same fashion as the first and that “[t]he net result is that the memory data bus transfers 4m bits of data in two memory bus clock cycles (four mbit transfers), with only two data accesses performed at each memory device on the module.” Ex. 1005 ¶ 42. Thus, Halbert’s memory module outputs data to the system memory data bus at twice the rate that each of ranks 140 and 142 outputs data. See Ex. 2003 ¶¶ 68–73 (Dr. Przybylski’s credible testimony explaining Halbert’s data rates).” slip op. at 11

    “network-based portal” as recited in the challenged claims is sufficiently broad to encompass residing at either a client or server side of a network, as Petitioner contends, or is limited to residing at the server side, as Patent Owner contends.

    “5. Summary As we note above, we find certain of Patent Owner’s arguments adequately rebutted by Petitioner, such that we do not consider them in our assessment. Nevertheless, Patent Owner retains compelling arguments for its proposed construction, supported by expert testimonial evidence, including dictionary definitions and the ’038 patent specification’s reference to a “portal or a gateway.” We find such references more compellingly refer to “portal” and “gateway” as synonyms rather than alternatives. In addition, Patent Owner provides convincing evidence and argument that rebuts the concern raised by the Board at institution whether Patent Owner’s proposed construction would exclude preferred embodiments. Petitioner, who bears the overall burden, addresses that concern only with attorney argument, which we accord less weight. In light of these considerations, we construe “network-based portal” as Patent Owner advocates, namely as residing on a server side of a network.” slip op. at 27

    “Both the preamble and the body of independent claim 7 recite “a network-based portal.” Ex. 1001, 21:53, 21:58, 22:2, 22:14–15, 22:19, 22:20–21, 22:27, 22:33, 22:38–39; see PO Resp. 21 (Patent Owner noting repeated recitation of “network-based portal” in independent claim 7). Contending that a “network-based portal” is “a web page or interface that connects clients to a network,” Petitioner identifies client-resident user-interface 112 of Diacakis as meeting the claim’s requirement for such a feature. Pet. 34–35. As explained above, after evaluating the record evidence developed during the trial, we do not adopt such a broad construction of “network-based portal.” Supra § II.D. Instead, we construe “network-based portal” as Patent Owner advocates, namely as residing on a server side of a network. Id. Because Petitioner does not show that Diacakis discloses a “network- based portal” as so construed, we conclude that Petitioner does not show, by a preponderance of the evidence, that independent claim 7 is unpatentable under 35 U.S.C. § 103(a) over Diacakis. The same deficiency exists with respect to Petitioner’s analysis of independent claims 38 and 46. See Pet. 55–56 (Petitioner’s analysis of claim 38 relying substantially on analysis of claim 7), 57–58 (Petitioner’s analysis of claim 46 relying substantially on analysis of claim 7).

    “One difficulty with Petitioner’s position is that it treats the refractive index and extinction coefficient as independent variables in its argument. But the prior art is clear that the adjusting the hydrogen content of Si:H to achieve a desired extinction coefficient necessarily affects the refractive index—and, as we discuss above, that such adjustments do so in a direction counterproductive to the combination of parameters the inventors sought. And we agree with Patent Owner that the refractive index and extinction coefficient “are not parameters subject to simple adjustment, but properties resulting from the parameters of the fabrication process.” PO Resp. 52 (citing Ex. 2001 ¶¶ 121–122; Ex. 1016, Figs. 2–3). At the Oral Hearing, Petitioner conceded that Patent Owner’s characterization is accurate when considering the hydrogenated silicon material. See Tr. 65:7– 12. When Petitioner refers to the refractive index and extinction coefficient as result-effective variables, Petitioner means that those parameters are variables that can affect the properties of the claimed optical filter. See id. at 64:6–65:12. As we note above, Petitioner’s argument thus presumes that the refractive index and extinction coefficient can be independently adjusted to achieve desired filter properties—but the asserted prior art teaches against such independence because the known method of adjusting the hydrogen content of Si:H not only affects both the refractive index and extinction coefficient, but does so in a manner counterproductive to the inventors’ objective.” slip op. at 35

    “phrase creates a degree of ambiguity, we are mindful that “the claims themselves provide substantial guidance as to the meaning of particular claim terms” and that “the context in which a term is used in the asserted claim can be highly instructive.” Phillips, 415 F.3d at 1314. In this instance, the related phrasing that appears in the “automatically adding” and “causing” limitations of issued independent claim 1 is illuminating. Both of those limitations refer to “the controllable function of the controllable appliance that was identified by the data received from the controllable appliance.” Ex. 1001, 17:11–14, 17:21–24 (emphasis added). There is no question that the only antecedent for “the data” in these limitations is the “data that functions to identify a controllable function of the controllable appliance” recited in the “receiving” limitation. See id. at 17:8–9. And there is no apparent room in the language “that was identified by the data” for the introduction or consideration of such “other information” that Petitioner would like to use “in connection with” the recited “data” to identify the controllable function.

    “Petitioner reasons that a person of ordinary skill in the art would have combined such teachings from HDMI 1.3a with Chardon’s system because HDMI 1.3a “is a technical guide for the interoperability of the HDMI standard and how HDMI enabled devices operate,” and that “Chardon relies on HDMI capabilities to facilitate communication and monitoring-device state changes in its system.” Pet. 30–31 (citing Ex. 1005, 4:18–21; Ex. 1010, 17; Ex. 1003 ¶¶ 130–131).

See supra § II.C. As Patent Owner asserts, HDMI 1.3a “does not contemplate the exchange of any information that itself functions to identify a controllable function of a playback device.” PO Resp. 24 (emphasis added). All that the “Deck Status” message indicates in the example of Figure 17 is that the current status of the playback device is “Stop.” We also are not persuaded by Petitioner’s and Dr. Russ’s argument that HDMI 1.3a’s Tables 13 and 26 disclose that “Deck Info” information is returned with the “Deck Status” message, and that such “a deck status message includ[es] the features that the device can provide (e.g., play, pause, stop, etc.).” Pet. 41; Ex. 1003 ¶ 117.

    “Reply: that the first internal temperature is acquired using the setpoint. See Pet. Reply 20. The Consolidated Trial Practice Guide states that a “Petitioner may not submit new evidence or argument in reply that it could have presented earlier, e.g. to make out a prima facie case of unpatentability.” Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 2019)10 73. Although “a reply . . . may . . . respond to arguments raised in the preceding brief,” “[r]espond . . . does not mean proceed in a new direction with a new approach as compared to the positions taken in a prior filing.” Id. at 74. As discussed below, we find Petitioner improperly shifted its position in the Reply by advocating a new approach. In the Petition, Petitioner argues that Wedekind teaches “acquiring at least a first internal temperature inside said structure at a third time prior to said target time” by the “continuous measurement of various air temperatures” including the internal temperature inside the structure. Pet. 42 (quoting Ex. 1006, code (57) and citing Ex. 1002 ¶ 97). According to Petitioner, “[t]he continuous measurement of temperatures includes measurement of a first a [sic] internal temperature inside said structure at or before time t3 in Fig. 2, which is the third time prior to said target time.” Id. (citing Ex. 1002 ¶ 98). Petitioner argues that “[e]ven during times of steady-state temperature, the temperature is being continuously measured to check against the current temperature setpoint.” Id. Nowhere does Petitioner mention acquiring a temperature by using the setpoint 10 Available at https://www.uspto.gov/TrialPracticeGuideConsolidated. temperature as opposed to a measured temperature. See Pet.; PO Sur-reply 9. In its Reply, Petitioner alternatively argues that the claim limitation is satisfied even if Wedekind uses the setback/setpoint11 temperature: Even Wedekind’s parameter Ti, however, would still meet the claim language. EcoFactor principally argues that Ti is not a measured temperature, but rather just a setpoint. A setpoint, according to EcoFactor, is at best a “predict[ion] [of] air temperature at or before time t3”. To this there are three responses. First, EcoFactor simply assumes that the “setback temperature” is a setpoint, but Wedekind refers to it in the relevant passage as “the setback temperature which exists at time, t3”. (Ex. 1006, 19:61)(Emphasis added). The phrase “setback temperature setpoint”, as used by EcoFactor, does not actually occur in Wedekind. Second, even if the setback temperature were a setpoint, the setpoint is a good estimate for the temperature (Ex. 1014, 19:23-21:3), and the claims do not require a measured “first internal temperature”, merely one that is “acquired”. Finally, even if the setback temperature of Wedekind were a predicted temperature, the ’753 patent works in exactly the same way, namely by using a “predicted initial temperature PT” as the temperature at the beginning of the recovery period. (Ex. 1001, 6:17-22)(Ex. 1014, 55:25-58:4). Thus, even if EcoFactor had made an express claim construction argument, the “first internal temperature” would not have been construed to exclude predicted temperatures.” slip op. at 22
