“persuaded us that applying the Phillips standard would affect our determination of this case. In fact, throughout this proceeding, Patent Owner has taken no position on claim construction. Prelim. Resp. 4; PO Resp. 6. The only claim term the Board construed in its Institution Decision is the term “deformities,” appearing in both challenged claims. Paper 11, 4. It was Petitioner who asserted that the ʼ370 patent “expressly defines” the term to mean “any change in the shape or geometry of the panel surface and/or coating or surface treatment that causes a portion of light to be emitted.” Pet. 7 (citing Ex. 1001, col. 4, ll. 36–40). Patent Owner did not oppose that construction. Hearing Tr. 45:20–25. In fact, Patent Owner pointed out that the construction of “deformities” proffered by Petitioner was agreed to and adopted by the district court. PO Resp. 7; Hearing Tr. 47:7–15. Patent Owner’s counsel agreed at the oral hearing that the expiration of the ʼ370 patent has no impact on that construction. Id. at 47:1– 18. Nor does Patent Owner seek any other particular constructions in light of the ʼ370 patent’s expiration. Id. at 46:9–19. In short, Patent Owner points to nothing that would change if the Phillips standard were applied. In light of the foregoing, we see no reason to modify our previous construction of “deformities” based either on the expiration of the ʼ370 patent or positions of the parties as developed during the trial, and adopt that construction for this Final Written Decision. Nor do we see the need to make any further constructions of the claims for the purposes of this decision that would be affected by the expiration of the ʼ370 patent or the Phillips standard.” slip op. at 5

“We are not persuaded by Patent Owner’s arguments attempting to distinguish Pristash. Instead, we are convinced by Petitioner’s arguments, citations to the Pristash disclosure, and the testimony of its expert, Dr. Escuti, that Pristash describes a panel that meets this limitation. Specifically, Pristash, taken as a whole, discloses in Figures 5 and 6 the combination of prismatic deformities with other deformity types (e.g., lenticular) on the same side of the light emitting panel as this claim requires. We are supported also in this conclusion by the testimony of Mr. Werner, who agreed that a lens is a different type of deformity than a prism. Werner Dep. 111:12–17. At oral argument, Patent Owner’s counsel asserted that Pristash does not meet this limitation because prismatic surface 48 in Figure 6 is not a “deformity” as the claims require, but is itself the surface of the panel. Hearing Tr. 49:7–10. We are not persuaded by this argument. There is no requirement in the claims that the deformities be on separate surfaces, only that they be on the same side of the panel. Moreover, the ʼ370 patent specifically refers to “prismatic surfaces, depressions or raised surfaces of various shapes” as examples of light extracting deformities. Ex. 1001, col. 5, ll. 57–60. We credit also Petitioner’s evidence, summarized supra (which Patent Owner does not challenge), that the other elements of claim 15 are found in Pristash. We conclude, therefore, that Petitioner has demonstrated, by a preponderance of the evidence that claim 15 would have been obvious over Pristash.” slip op. at 15

“Fischer teaches that the comparators in coherent demodulator 114 convert a “‘spread spectrum modulated’ analog signal into a digital signal,” as opposed to “other analog signals.” See PO Resp. 13. To the contrary, Fischer states that “[t]he communicators preferably transmit and receive messages over a wireless physical layer provided by a direct-sequence, spread spectrum (DSSS) radio data link.” Ex. 1004, 14:24–27. Fischer further explains that “[s]ince many of the signals in the coherent demodulator 114 are analog signals, the coherent demodulator 114 includes comparators to establish digital waveforms.” Ex. 1004, 16:58–60. As shown in Figure 5 of Fischer, the coherent demodulator 114 is followed by spread spectrum correlator and decoder 130, which “handles the demodulator 114 output to regenerate the unspread data.” Ex. 1004, 17:58– 60. Thus, we agree with Petitioner, as supported by Prof. Ding, that a person of ordinary skill in the art “would have understood Fischer to describe that the demodulator 114 converts the analog DSSS modulated messages received by antennas 100/102 to digital signals and outputs these digital DSSS modulated messages in I and Q format to spread spectrum correlator and decoder 130.” Reply 3–4; Ex. 1013 ¶ 5.” slip op. at 18

“The Petition makes no mention of Nakamura in its discussion of the additional limitations of claims 2 and 11. Yet in reply, Petitioner argues that “[i]n view of Fischer’s variable length preambles, a [person of ordinary skill in the art] would have found it obvious to utilize Nakamura’s timer function and its repetitive duration function.” Reply 15. Petitioner may not rely on a new argument asserting that Nakamura teaches the additional limitations for claims 2 and 11 presented for the first time in its Reply. Moreover, Petitioner fails to address how either Fischer or Nakamura teaches means for adjusting means for timing when Fischer contains no timer, and when the timer of Nakamura is described as being based on a predetermined period of time. See Ex. 1005, 6:31–36 (“timer 34 permits the switch 14 to transfer from terminal A to terminal B after the lapse of predetermined time”); see also Ex. 2006, ¶¶ 83–84. Petitioner’s contention that “Nakamura’s timer is also flexible” is insufficiently supported by any reference to either Nakamura or the declaration of Prof. Ding. See Reply 16–17; see also Ex. 1013 (no discussion of claims 2 or 11). Petitioner has not demonstrated that the features of claims 2 or 11 are disclosed by the combination of Fischer and Nakamura. 5. Claims 4, 5, 6, 13, 14, 16, and 18–20 Petitioner has persuasively shown that each of the additional limitations of dependent claims 4, 5, 6, 13, 14, 16, and 18–20 are taught by the combination of Fischer and Nakamura. For example, claims 4, 14, and 19 all require a “single monolithic device.” Petitioner has shown that Fischer RF modem 96 is a single monolithic device, and that Fischer communicator 60 is a circuit contained on a single monolithic device that includes RF modem 60. See Pet. 27–28; Ex. 1003 ¶¶ 41–42. Petitioner has also shown that RF modem 96 includes coherent demodulator 114 that provides in-phase and quadrature data outputs that are responsive to an analog signal that has in-phase and quadrature components, corresponding to the requirements of an analog signal “in the form of in-phase and quadrature components” as recited in claims 5 and 16. See Pet. 28–29; Ex. 1003 ¶ 38. With respect to the limitations of claims 6, 16, and 20 requiring PN modulation and phase shift keyed modulation, Petitioner has shown that Fischer discloses RF modem 96 supports BPSK or QPSK, and that it would have been obvious to implement direct sequence spread modulation by using PN modulation. See Pet. 29; Ex. 1003 ¶¶ 34, 37. We are also persuaded that Fischer discloses the “antenna selection circuitry” as recited in claim 13 and the “serial data stream” as recited in claim 18.

“Patent Owner contends that “[i]f reliability alone is the concern,” then “the most reliable method is to use BPSK for the entire packet (as taught by Fischer).” PO Resp. 38. We are not, however, persuaded that “reliability alone is the concern.” Nakamura and Fischer clearly teach a benefit to using both BPSK and QPSK consisting of improved reliability for BPSK with enhanced speed from QPSK. Thus, we find Patent Owner’s contention that those of skill “would not look beyond the teachings of Fischer” unpersuasive. See id. Likewise, Patent Owner’s contention that Fischer already teaches improved reliability by using longer preambles has no bearing on whether one of ordinary skill in the art would have also looked to Nakamura for other means of improving reliability.

“the art “would have appreciated the benefit of including multi-carrier modulation in the Wu system” because “Wu itself references the 802.11a standard as a multi-carrier OFDM scheme that is able to achieve data rates that are faster than the 802.11b transmission rates used in the Wu system.” Id. at 48 (citing Ex. 1120 ¶¶ 43–47, 65–68; Ex. 1108, 411). Petitioner contends that [w]ith this motivation in mind a [person of ordinary skill in the art] would have recognized that adding the multi-carrier 802.11a modulation scheme to the modulation schemes already available in the Wu system would have been a simple addition, if a technique was available for using a channel estimate obtained from data modulated according to a single carrier modulation scheme for acquisition of data modulated according to a multi-carrier modulation scheme[,] and supports that contention with testimony by Dr. Almeroth. Id. at 48 (citing Ex. 1120 ¶¶ 43–47, 65–68). Petitioner identifies such a technique as disclosed by Böhnke. Id. at 49. Böhnke “relates to the mapping of data and pilot symbols in an OFDM-system.” Ex. 1113, col. 1, ll. 4–5. Figure 2 of Böhnke is reproduced below. Figure 2 illustrates a sequence that includes a first OFDM modulated signal S1, a midamble MA that can be OFDM modulated or single-carrier modulated, and a second OFDM symbol S2. Id. at col. 4, ll. 36–41. The midamble can be used for the transmission of pilot symbols, which “are necessary for a channel estimation such as to effect coherent detection of e.g. OFDM-modulated signals,” and such pilot symbols can be created by a single carrier modulation with a known training sequence.

Böhnke, thus, uses the channel estimation obtained from the single-carrier training sequence to detect multi-carrier OFDM symbols by matching bandwidth and performing synchronization. Id. at col. 2, ll. 43–45, col. 2, ll. 61–62. Petitioner reasons that the Böhnke channel-estimation techniques “provide a way to combine a high-rate, multicarrier OFDM data transmission scheme with a single carrier training sequence” and that [w]ith this background, a [person of ordinary skill in the art] investigating options for including the multi-carrier 802.11a standard in the Wu system would have appreciated that Bohnke’s channel estimation techniques could be applied to Wu’s single-carrier 802.11b preamble and used for acquisition of data modulated according to multi-carrier 802.11a.” slip op. at 12

“We agree with Patent Owner that Petitioner’s analysis of claim 22, which recites separate single-carrier and multi-carrier receivers, as well as a switch coupled to such receivers, is deficient. Petitioner’s assertion that claim 22 is unpatentable for “reasons similar to those explained in regards to claims 1-3 and 5” insufficiently addresses these limitations, which do not appear in claims 1–3 or 5.

“considerations are relevant. First, the Specification of the ’285 patent explains that the “flat cable transmits scanning control signals . . . instead of timing control signals.” Ex. 1001, col. 4, ll. 26–28 (emphasis added). In the related proceeding, we observed that this portion of the Specification “suggests a distinction between scanning control signals and timing control signals,” but “does not support unambiguously Patent Owner’s position of complete independence between scan control signals and timing control signals.” Canon Inc. v. Intellectual Ventures I LLC, Case IPR2014-00535, slip op. at 8 (PTAB Sept. 23, 2015) (Paper 37). We note that a construction of “scan control signals” and “timing control signals” that effected such complete independence would render the negative limitation that “the received scan control signals do not comprise any timing control signals” superfluous in the claims of the ’285 patent. “A claim construction that gives meaning to all the terms of the claim is preferred over one that does not do so.” Merck & Co., Inc. v. Teva Pharms. USA, Inc., 395 F.3d 1364, 1372 (Fed. Cir. 2005) (citing Elekta Instrument S.A. v. O.U.R. Sci. Int’l, Inc., 214 F.3d 1302, 1307 (Fed. Cir. 2000)); see Gen. Am. Transp. Corp. v. Cryo- Trans, Inc., 93 F.3d 766, 770 (Fed. Cir. 1996) (rejecting district-court claim construction that rendered claim requirement superfluous).

“generation of timing control signals in response to receipt of scan control signals, “wherein the [received] scan control signals do not comprise any timing control signals.” Petitioner contends that all limitations of the independent claims, including this recitation, are disclosed by Hayashi. Pet. 17–25. Specifically, Petitioner contends that the set of signals WR*, A<0>, and CDATA<7, . . . ,0> are “scan control signals” and that the signals output by driving clock generating circuit 112 are “timing control signals.” Id. at 17–19. Petitioner identifies a distinction in the functionality of signals WR*, A<0>, and CDATA<7, . . . ,0>, and the functionality of signals output by driving clock generating circuit 112. Because the signals output by the driving clock generating circuit are produced in response to a data value carried by CDATA<7, . . . ,0>, Petitioner contends that CDATA<7, . . . , 0> is not itself a timing control signal. Id. at 19. According to Petitioner, only signals output by Hayashi’s driving clock generating circuit are timing control signals, not signals traveling to the driving clock generating circuit. Id. Petitioner supports its argument with testimony by Richard Carley, Ph.D. Ex. 1002 ¶¶ 52–60, 121–128, 196–203.” slip op. at 12

“Petitioner thus contends that all limitations of the independent claims, including the requirement that “the [received] scan control signals do not comprise any timing control signals,” are disclosed by Tsuboi and Wada. Pet. 41–54. Patent Owner responds that “[p]eople of ordinary skill in the art would readily recognize Tsuboi’s primary scanning synchronization signal and Wada’s synchronization signal TR are timing control signals.” PO Resp. 25. Similar to its argument directed at the Hayashi-based grounds, Patent Owner relies on testimony by Dr. Zech that a “CPU is understood by one of ordinary skill in the art to control a timing generator.” Id. at 25–26 (citing Ex. 2004 ¶ 69). Patent Owner observes that “Tsuboi’s primary scanning synchronization signal is generated . . . by CPU 21” and that “Wada’s synchronization signal TR is also generated by a timing generator, namely control signal generating circuit 27.” Id. (citing Ex. 1005 ¶ 39; Ex. 1006 ¶ 18). Patent Owner further notes that Petitioner’s expert, Dr. Carley, acknowledged during his deposition that the primary scanning synchronization signal “is used to align the reading out of the CCD in time, meaning it starts it up.” Id. at 26 (citing Ex. 2006, 72:14–16). Under the claim construction we have adopted, we are persuaded by Patent Owner’s analysis. Based on the evidence before us, we find that Petitioner has not demonstrated that Tsuboi or Wada discloses “wherein the received scan control signals do not comprise any timing control signals,” as recited in each independent claim. Patent Owner’s analysis thus applies to all claims of the ’285 patent. Accordingly, we conclude that Petitioner has not established, by a preponderance of the evidence, that any claim of the ’285 patent is unpatentable over Tsuboi and Wada together or in combination with other art.” slip op. at 17
