As there is no controversy, we need not, and do not, construe the meaning of “cognate.” However, Patent Owner’s requirement that “at least one other of the plurality of users” is specifically cognate to “the user” who was sent the content is plainly recited in the claim language itself.

The package substrate 310 includes a package common ground rail 360, and the segmented SoC ground rails 350, 355 are independently connected to the package common ground rail 360 via separate connections 370, 375 respectively.”). As set forth above, Dr. Foty describes the three ground lines in Saint Figure 7-7 as “segmented rails” when discussing the combination of Saint and Haralabidis, thus equating the three ground lines in Saint Figure 7-7 with Haralabidis’ segmented ground rail. Ex. 1003 ¶ 368. Neither Petitioner nor Dr. Foty, however, adequately addresses how or why a POSITA would have understood that the three separate grounds lines in Saint Figure 7-7 were “segmented rails” like the segments of the single ground line described in Haralabidis. In contrast, Dr. Khatri credibly testifies: Haralabidis teaches the use of a “common ground rail” to connect “segmented ground rails.” Haralabidis, 3:9–22, 3:34– 40, 3:65–4:12. A POSITA would understand “segmented ground rails” to refer to a single ground signal that has been “segmented.” That is fundamentally different from the design of Saint’s Figure 7-7 that Dr. Foty relies on, which uses three different ground signals, GND1, GND2, and GND3—not a single ground signal that has been “segmented.” Because of that, a POSITA would not have been motivated to change the Figure 7-7 design completely to connect three separate signals (GND1, GND2, and GND3) together as Dr. Foty proposes. Ex. 1003 ¶ 368. Indeed, for these reasons, a POSITA would have understood Haralabidis’ teachings of a “common ground rail” are inapplicable to Saint’s Figure 7-7. Ex. 2010 ¶ 129. Petitioner’s arguments and Dr. Foty’s testimony with respect to the modification of Saint Figure 7-7 leave an analytical gap that does not apprise us of why a POSITA would have modified Saint Figure 7-7 to include a common ESD bus as described in Haralabidis.” slip op. at 37

    “For these reasons, we find that Yoshinaga’s statement that “[r]eference potential pads are not shown to simplify the drawing” indicates that reference potential pads are not depicted in Yoshinaga Figure 6, and determine that Yoshinaga Figure 6 does not disclose “a plurality of pad groups, adjacent and connected to the plurality of ESD buses” as recited in claim 6. Petitioner also argues that a POSITA would have understood that power supply pads 3, 4, and 58 in Yoshinaga “could just as readily be used as reference pads” and it would have been obvious “to use the pads immediately next to the saved areas as reference pads (e.g., pads 5 and 6) as pad assignments were left to the designer’s discretion.” Pet. 31 (citing Ex. 1003 ¶¶ 137–139). Petitioner asserts that “selecting which pads to use for ground, power signals, etc. is a design choice that depends on factors like chip size, the number of I/O signals, and the number of pads available.” Pet. 31 (citing Ex. 1003 ¶ 137–139).

Neither Petitioner nor Dr. Foty adequately explain, however, why a POSITA would have made this specific design choice, namely, replacing power supply pads 3, 4, and 58 with reference pads.

Cir. 2016))). Petitioner offers the general proposition that pad assignments are left to the designer’s discretion, but this does not provide a reason why a POSITA would have been motivated to modify Yoshinaga Figure 6 as proposed. Pet. 31; Ex. 1003 ¶¶ 137–139. We have determined that Yoshinaga does not show (rather than does not label) reference pads. Because all of Yoshinaga’s illustrated pads are power supply pads, Petitioner’s proposed reassignment of pads would not be a simple matter of rearrangement of an existing mixture of power supply and reference pads, but require that reference pads be imported from elsewhere, and power supply pads be moved to some unspecified location. Petitioner’s arguments and Dr. Foty’s testimony with respect to the modification of Yoshinaga Figure 6 leave an analytical gap that does not apprise us of why a POSITA would have modified Yoshinaga Figure 6 to include reference pads in the place of power supply pads 3, 4, and 58.

    “Based on the record before us, we agree with Petitioner that “on a surface” should be interpreted in line with the definition of “on” set forth in the ’711 patent. Ex. 1001, 4:1–6. We particularly note that the ’711 patent states that “‘on’ . . . should be interpreted in the broadest manner” and that “on” is not limited to “directly on.” Id. Instead, the ’711 patent states that “‘on’ also includes the meaning of ‘on’ something with an intermediate feature or layer therebetween.” Id. Patent Owner agrees that this definition controls the “standalone ‘on’” term such that A may be on B even if there is an intervening layer between them. Tr. 55:8–11 (“The standalone ‘on,’ we agree in the context of the patent, you can have intervening layers. I think the patent is clear about that.”). Claim 14 recites that the etch-stop layer is “on” something; i.e., “on a side surface and a top surface of each step.” Ex. 1001, 16:20–22. Patent Owner agrees that a surface is a “something.” Tr. 56:5–8 (“surface obviously is a something”). Substituting the “a “‘on’ something with an intermediate feature or layer therebetween” results in claim 14 reading as, “on a surface with an intermediate feature or layer therebetween.” Unlike “directly on,” which specifies the relation between two things, “a surface” may merely indicate the thing that something is “on,” particularly when “on” is “interpreted in the broadest manner” as expressly required by the ’711 patent.” slip op. at 7

    “Although Dr. Campbell testified in his deposition in response to Petitioner’s counsel that “on the surface” requires direct contact with the surface, his interpretation was based on “embodiments of” the patent rather than a general understanding of a person skilled in the art confronted with that term. Ex. 1027, 122:6–25, 124:6–23 (“I’m not sure if there are other sources for that, but it was on the ’711, so I’ve taken it there.”). Dr. Campbell, upon questioning from Patent Owner’s counsel, later stated that “an expert in semiconductor fabrication” would understand “on the surface” to mean “contact between one layer and another . . . with nothing in between.” Id. at 146:25–147:6. However, Dr. Campbell did not explain why such an interpretation is particular to the semiconductor fabrication art, or provide other explanation or support for this statement, which is in tension with the definition of “on” in the ’711 patent. Accordingly, we significantly discount the weight accorded to that statement. Phillips, 415 F.3d at 1318 (stating, “conclusory, unsupported assertions by experts as to the definition of a claim term are not useful to a court. Similarly, a court should discount any expert testimony ‘that is clearly at odds with the claim construction mandated by the claims themselves, the written description, and patent.’”). On balance, Dr. Campbell’s testimony is best understood as a description of certain Figures of the ’711 patent rather than a representation of an ordinarily skilled person’s understanding of the term “on the surface.” See Ex. 2009 ¶ 47 (describing Figs. 1, 3, and 4 as depicting layers in contact with the underlying layer or substrate). For example, Dr. Campbell describes Figure 9A as having a barrier layer “on and directly contacting the top and side surfaces of each step.” Id. ¶ 28 (emphasis added) (citing inter alia Ex. 1001, 7:6–67). Dr. Campbell does not explain why, beyond the fact that many Figures show layers as adjacent and in contact, a person of ordinary skill in the relevant art would understand those Figures to limit the claim language rather than illustrating particular embodiments that fall within a broader scope of claims 14 and 15.

    “information” should be given its plain and ordinary meaning as “data,” and that Patent Owner’s narrower construction of “first information” and “second information” lacks sufficient support in the intrinsic record. We agree with Petitioner that the ’802 patent Specification defines “information” as data when it uses the phrase “information (i.e., data).” See Ex. 1001, 5:60–62 (“Information (i.e., data) to be transmitted may be received in a baseband digital system 250, such as a wireless digital baseband processor.” (emphasis added)), 11:30–32 (“In this example, the signals 911 and 912 carry the same information (data).” (emphasis added)).

See Pet. 76–77 Ex. 1003 ¶ 235. Petitioner’s only rationale for this modification to Fernandez is that “[a] single amplifier has several advantages compared to multiple amplifiers, including lower complexity, a single (vs. multiple) potential point of failure, and lower cost,” and that one of ordinary skill “would have found a single amplifier to be a simple matter of design preference.” Pet. 76–77.

    “We find credible and agree with Dr. Cooklev’s testimony that the predistortion signals from tables 17-1 and 17-2 “are cancelled out by Suzuki’s amplifier” 28. Ex. 2013 ¶ 50. Dr. Cooklev supports his opinion by referring to paragraph 1 of Suzuki, which states that Suzuki’s invention is directed to “a multi-band lookup table type predistorter” (such as the one implemented using lookup tables 17-1 and 17-2 in Figure 6) that “compensates for a distortion of a power amplifier.” Ex. 2013 ¶ 54; Ex. 1004 ¶ 1. Dr. Cooklev’s opinion is also supported by paragraph 3 of Suzuki, which explains that a conventional digital predistorter uses a lookup table “for linearizing non-linear characteristics of an amplifier.” Ex. 1004 ¶ 3; Ex. 2013 ¶ 54. Dr. Cooklev further supports his opinion by relying on Suzuki’s disclosure in paragraph 46 that power amplifier 28 is “subject to distortion compensation” by the predistorter, and that distortion components in the signal output by the amplifier are canceled by “distortion compensation data [that] are read out from the lookup tables 17-1 and 17-2 and provided to the adders 13-1 and 13-2, respectively.” Ex. 1004 ¶ 46; Ex. 2013 ¶ 54. And, Dr. Cooklev’s opinion is supported by Suzuki’s disclosure in paragraph 47 that the distortion compensation added by adders 13-1 and 13-2 add the distortion compensation data from lookup tables 17-1 and 17-2 “to perform distortion compensation (addition of predistortion)” to “signals to be transmitted.” Ex. 1004 ¶ 47; Ex. 2013 ¶ 54. Petitioner agrees that the distortion compensation data from lookup tables 17-1 and 17-2 “are added to the respective frequency band from” input signal ST “in order to predistort the output signal, which is then transmitted,” and does not dispute that the distortion compensation data from lookup tables 17-1 and 17-2 is ultimately cancelled out by the distortion created by amplifier 28. Pet. Reply 8. In light of the above evidence, we agree with Patent Owner that Suzuki’s distortion components from lookup tables 17-1 and 17-2 in Figure 6 (which Petitioner relies on for the first and second digital signals in limitations 10a and 10b) are cancelled out by the distortion created by power amplifier 28 before the signal is ultimately transmitted. We agree with Petitioner that these first and second digital signals include data in the form of distortion compensation data. However, because these signals are cancelled by the distortion from amplifier 28 before transmission, the data from these signals is never transmitted. Thus, the first and second digital signals identified by Petitioner (the distortion compensation data from lookup tables 17-1 and 17-2) do not comprise data “to be transmitted,” as limitations 10a and 10b require.” slip op. at 35

    “The claim language and specification define and describe an “activation cue” in functional terms: a data communication from an external source is received by the cell phone and recognized as an activation cue if it causes the switching element to be assigned its first (activated) state.

Patent Owner agrees that “upon an activation cue being received by portable electronic device 10, switching element 44b switches to its activated state.” Resp. 19 (quoting Ex. 1001, 10:14–16). The activation cue may be a predetermined bit sequence, a predetermined contactless data transmission, continuously emitted, pulsed, or punctual, but these are unclaimed non-limiting embodiments of the preferred form of data transmission.

    “operatively linked to said electronic circuit” under 35 U.S.C. Section 112, sixth paragraph or not, the result is the same. We note there is no presumption of applying means-plus-function analysis to the switching element, because the limitation does not use the words “means for” that would mandate such claim construction treatment, and “switching” may invoke structure as well as function. See Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1349–1350 (Fed. Cir. 2015) (en banc) (holding that “use of the word ‘means’ creates a presumption that § 112, ¶ 6 applies”). Regardless, we look to the meaning of the claim phrase at issue in view of the specification. We determine that the ’294 patent provides a clear, concise meaning for the switching element upon which both parties rely for construction. Patent Owner’s express agreement with Petitioner, that the claimed switching element is described in the ’294 patent as “any type of device allowing data to be conveyed according to alternate data conveyance operations in response to an activation cue being received by transceiver 18 or not,’” is particularly telling because it is not consistent with Patent Owner’s argument that the switching element means “switching of the data.” Resp. 7, 31 (citing Ex. 1001, 9:28–318). The claim language does not recite, and the specification does not describe, the switching element as a device that switches the data. Therefore, we determine the claimed “data conveyance switching element” means any type of switching device that allows data to be 8 We presume Patent Owner’s citation to “Exh. 2001, 9:28-31” on page 7 was intended to be a citation to the ’294 patent (Ex. 1001), as cited on page 31. whether or not an “activation cue” is received by the cell phone “cue receiver.”” slip op. at 21

    “[external] data exchange device” as a device with a data transceiver coupled to a circuit that carries out the function of exchanging data. Pet. 7–8 (citing Ex. 1001, 2:14–17, 4:7–14, 9:3–6; Ex. 1003 ¶¶ 67–68). As above, whether we construe the “[external] data exchange device” under 35 U.S.C. Section 112, sixth paragraph or not, the result is the same. Patent Owner, quoting the description of a data exchange device in the ’294 patent, contends that a “[external] data exchange device” “can be any sort of data exchange device comprising an electronic circuit (not shown) therein and a data transceiver 9a.” Resp. 8 (quoting Ex. 1001, 9:4–6). Patent Owner also responds to the Petition by clarifying that “[a]n external data exchange device is not a transceiver but a device with a transceiver.” Id. (citing Ex. 2001 ¶ 48). Petitioner argues in reply that Patent Owner does not contest Petitioner’s mappings of Mooney’s “cordless telephone base unit” or “cellular network infrastructure” to the claimed data exchange devices, such that no construction is necessary to resolve the dispute. Reply 5 (citing Resp. 16–37; Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011)). Limitations [1.c] and [1.d] recite “a first [second] data transceiver operatively linked to said electronic circuit [in the cell phone],” both of which are defined functionally as “for exchanging data between said electronic circuit [in the cell phone] and a first [second] external data exchange device over a first [second] communication link.” Nothing in the the other independent claims, further limits the form or function of the “[external] data exchange device,” although a device external to the cell phone may invoke additional structure. We determine the plain meaning of “[external] data exchange device” as claimed and described in the ’294 patent governs: any [external] device that comprises an electronic circuit and data transceiver for exchanging data with the electronic circuit in the cell phone over a communication link. slip op. at 22
