      “e. Summary For the reasons described above, we find that a person of ordinary skill in the art at the time of invention would have had reason to combine Yamamoto’s and Nishimoto’s teachings as asserted by Petitioner and that the combination teaches all of claim 13’s limitations. Accordingly, Petitioner has shown by a preponderance of the evidence that the subject matter of claim 13 would have been obvious over Yamamoto and Nishimoto.” slip op. at 21

      “tunable compensators is a contingent argument, applicable only if one reads claim 13 to require a certain transmission rate. PO Resp. 21–25. We do not read Petitioner’s argument as so constrained. Rather, we understand Petitioner to argue that a desire for higher transmission speeds would drive skilled artisans to use solutions such as Nishimoto’s tunable compensators, particularly in light of Nishimoto’s guidance regarding the ability to achieve high speeds with the system. See Pet. 21–23. In that regard, we agree with Petitioner that the increase in transmission rates from Yamamoto’s to Nishimoto’s disclosures would have given skilled artisans reason to consider Nishimoto’s teachings. Pet. Reply 16–18 (citing Ex. 1005 8:9–11; Ex. 1007, 12:37–39). As Petitioner points out, Nishimoto specifically discloses that higher-speed transmissions were more sensitive to dispersion. Pet. Reply 17 n.9. Thus, we find the desire for higher transmission speeds and the need for techniques such as taught by Nishimoto would have given skilled artisans reasons to combine Nishimoto’s disclosure regarding dispersion compensation with Yamamoto’s system to achieve Yamamoto’s goals regarding the dispersion maps for multiple channels. Further, Petitioner does not rest entirely on the desire for high-speed operation. Petitioner argues also that using Nishimoto’s adjustable compensators and feedback control would “yield an improved WDM system capable of automatic compensation for degradation of the optical signal waveform caused by both wavelength dispersion and polarization mode dispersion of the optical transmission path, resulting in further reduced size and cost.” Pet. 16 (citing Ex. 1003 ¶¶ 99, 101; Ex. 1007, 3:41–60, 4:3–58, Figs. 17, 20, 21), 29–30 (quoting Ex. 1007, Abstract, 3:37–40, 6:56–64, 7:53–56, 11:41–46, 17:53–55, 17:59–60; citing Ex. 1003 ¶¶ 114–115); accord id. at 14 (quoting Ex. 1007, 3:19–25). Patent Owner recognizes that basis for the combination but argues that the record lacks evidence to support Petitioner’s claim of reduced size and cost. PO Resp. 25–26. Patent Owner does not contest that the modification would give Yamamoto’s system the ability to automatically compensate for signal degradation from dispersion. Nishimoto discloses that as transmission speeds increase, “changes in wavelength dispersion characteristics due to temperature changes of optical fiber; and the influence by polarization mode dispersion” both “can not be neglected,” therefore requiring a system for automatically compensating for wavelength dispersion and polarization mode dispersion,” as taught by Nishimoto. Ex. 1007, 1:34–41. We find that a skilled artisan would have had reason to make the combination because the system would gain capability for automatic compensation. Regarding reduced size and cost resulting from the combination, Patent Owner does not provide any contrary evidence and we conclude that Nishimoto’s statements regarding the benefit of its invention also would have motivated skilled artisans to make the combination. See Ex. 1007, 3:17–26 (“to thereby provide a dispersion compensating apparatus of reduced sizes at a reduced cost”).” slip op. at 18

      “Although Petitioner contends “a POSITA would have been motivated to provide greater protection for the decimal integer portion (an error in which would be magnified versus an error in the decimal fraction portion)” in Padovani (Pet. 33), Petitioner does not identify any passage or combination of passages in Padovani that teaches or suggests providing, or even the need to provide, greater protection for one decimal portion than the other decimal portion, let alone by using “different coding schemes for the different parts.” Id. As Patent Owner asserts, “Padovani discloses using a single code to encode the DRC message[,]” and “does not teach using multiple codes to encode different portions of the DRC message.” Prelim. Resp. 14 (citing Ex. 1009, 45:20–22 (emphasis added)). We recognize that Petitioner’s Declarant, Dr. Min, testifies that, “by virtue of Padovani contemplating the use of an (n,k) coding scheme,” the POSITA “would have naturally sought out similar coding schemes [as those of Gils] to protect DRC messages.” See Pet. 41 (citing Ex. 1017 ¶ 156). Dr. Min further testifies that “a POSITA would have been motivated to provide greater protection for certain bits by selecting appropriate code words generated by one or more of the coding schemes contemplated by Gils,” and thus, use “different coding schemes for the different parts.” Ex. 1017 ¶ 132. Dr. Min’s testimony, however, does not address adequately why one of ordinary skill in the art would have used together different coding schemes from Gils, let alone a separate scheme for certain bits over the other bits. As Dr. Min testifies, “a single UEP coding scheme could also be used depending upon how a POSITA would have wanted to implement unequal error protection.” Ex. 1017 ¶ 132; see Pet. 33 (citing Ex. 1017 ¶ 132). As such, Dr. Min acknowledges that a single unequal error protection coding scheme could be used as well as applying different coding schemes to different parts of a message. Here, Dr. Min’s testimony that a single unequal error protection coding scheme could be used further undermines Petitioner’s position that one of ordinary skill in the art would have used the different coding schemes for different parts as set forth in Gils. Thus, Dr. Min’s testimony does not adequately explain why one of ordinary skill in the art would have applied different coding schemes from Gils to the DRC message of Padovani, much less in the manner proposed by Petitioner, of providing greater protection for the decimal integer portion than the decimal fraction portion, especially when Padovani discloses “using a single code to encode the DRC message.” See Prelim. Resp. 14 (citing Ex. 1009, 45:20–22).” slip op. at 14

      “Here, for these reasons discussed above, we conclude that Petitioner has not provided sufficient evidence from prior art references or Dr. Min’s declaration testimony to support its contention that one of ordinary skill in the art would have used Gils’s techniques to encode Padovani’s DRC message in the manner required by the claims—such that the most significant bit of the plurality of bits is encoded to be less susceptible to errors. Petitioner also has not demonstrated articulated reasoning with rational underpinning to support the legal conclusion of obviousness. See PAR Pharm., Inc. v. TWI Pharm., Inc., 773 F.3d 1186, 1193 (Fed. Cir. 2014). Instead, we conclude that Petitioner used improper hindsight to reconstruct the claimed subject matter by using the claims as a guide to combine the prior art references. Grain Processing Corp. v.

      “Moreover, Dr. Min’s contention that “[t]he nature of binary numbers (or other base-x number systems) means that the leftmost bit of any binary number is the most significant bit” (Ex. 1017 ¶ 154) is conclusory. As Patent Owner points out, “Dr Min’s declaration, however, merely repeats the allegations of the Petition without any explanation or citation to any supporting or corroborating evidence.” Prelim. Resp. 20 (citing Ex. 1017 ¶ 154). That is, “[t]here is no proffered evidence that it was well understood by a POSITA at the time that the leftmost bit in binary numbers, and specifically in the DRC message of Padovani, is the ‘most significant bit.’” Prelim. Resp. 20. For that reason, we give little weight to Dr. Min’s uncorroborated testimony that “the leftmost bit of any binary number is the most significant bit.” 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); In re Acad. of Sci.

      “We agree with Patent Owner. “A statutory disclaimer under 35 U.S.C. § 253 has the effect of canceling the claims from the patent and the patent is viewed as though the disclaimed claims had never existed in the patent.” Guinn v. Kopf, 96 F.3d 1419, 1422 (Fed. Cir. 1996) (citing Altoona Publix Theatres, Inc. v. Am. Tri–Ergon Corp., 294 U.S. 477 (1935)). An inter partes review cannot be instituted on claims that have been disclaimed and no longer exist. See 37 C.F.R. § 42.107(e) (“No inter partes review will be instituted based on disclaimed claims.”). This conclusion is consistent with other panel decisions addressing this issue. See, e.g., Intuitive Surgical, Inc. v. Ethicon LLC, Case IPR2018-00935, Paper 9, 9–10 (PTAB Dec. 7, 2018); Vestas-Am. Wind Tech. Inc. v. Gen. Elec. Co., Case IPR2018-01015, Paper 9, 12–14 (PTAB Nov. 14, 2018). Accordingly, we treat claim 3 as having never been part of the ’587 patent, and do not institute inter partes review on this claim. As discussed above, we regard claim 4 as the only challenged claim. See Sections I.A and I.E.” slip op. at 9

      “Accordingly, a plain reading of the reference does not support a finding that Bender teaches or suggests that the FEC scheme is used to encode the SNR itself. Therefore, we are not persuaded that Bender’s FEC description would have provided reason to look to Piret’s encoding techniques for encoding Bender’s “quality” information. That is, although we agree with the Petitioner that Piret teaches and suggests a method of encoding less significant bits differently from the more significant bits of each data word, wherein the most significant bit of the plurality of bits is encoded to be less susceptible to errors (Ex. 1005, 1:20–33), that alone is insufficient to support a conclusion of obviousness of providing an encoder that encodes Bender’s SNR “quality” information, as required by claim 4. That Piret discloses encoding transmitted information does not address the requirements set forth in KSR to provide articulated reasoning with rational underpinning to support the legal conclusion of obviousness. That is, the Petitioner’s obviousness position does not explain why a person of ordinary skill in the art would have encoded the SNR value in Bender, which may not even be transmitted, using Piret’s encoding method. Indeed, Petitioner does not direct us to persuasive evidence that encoding the SNR value would have been expected to provide any advantage, outside the teachings of the ’587 patent. Here, for these reasons discussed above, we conclude that Petitioner has not provided sufficient evidence from prior art references or Dr. Singer’s declaration testimony to support its contention that one of ordinary skill in the art would have used Piret’s techniques to encode Bender’s SNR values in the manner required by the claims—such that the most significant bit of the plurality of bits is encoded to be less susceptible to errors. Therefore, Petitioner has not demonstrated articulated reasoning with rational underpinning to support the legal conclusion of obviousness. See PAR Pharm., Inc. v. TWI Pharm., Inc., 773 F.3d 1186, 1193 (Fed. Cir. 2014).

      “may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” Id. In that regard, Petitioner’s Declarant, Dr. Singer, testifies that a person of ordinary skill in the art at the time of the ʼ587 Patent’s invention would have been a person having a Bachelor’s degree in electrical engineering or the equivalent plus three years of experience working with wireless communication systems or a Master’s degree in electrical engineering with an emphasis on communication systems or the equivalent plus one year of experience working with digital communication systems or in network engineering. Pet. 6; Ex. 1003 ¶ 39. At this juncture, Patent Owner does not dispute Dr. Singer’s assessment on the level of ordinary skill in the art. See generally Prelim. Resp. Based on the current record, we apply Dr. Singer’s assessment for purposes of this Decision. We also note that the prior art of record currently in the instant proceeding is consistent with this level of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1354–55 (Fed.
