“Finally, Petitioner argues obviousness over each of Banes and Calvignac. These assertions of obviousness rely on testimony on the understanding of a person of ordinary skill in the art of the “spare” code and flags as “out-of-band symbols.” Pet. 20−21. Petitioner also argues that it was “well-known” to include in-band symbols in data packets and to include out-of-band symbols in control indicators to obtain the benefit of allowing data payload information to be readily distinguished from control information. Pet. 63−64. The testimony cited in support relies on the disclosure of Shin ’464 for this statement.5 Ex. 1003 ¶ 225. The exact same disclosure of an 8-bit encoding technique that uses in-band and out-of-band symbols within a transmission is found in another Shin patent that is incorporated by reference in the ’905 patent and has overlapping inventors.

With respect to factor (b), RavenWhite does not provide an explanation as to how the teachings of Flash that were applied by the Examiner during prosecution of the ’823 patent are cumulative to the teachings of Hinton and Varghese applied by Home Depot in the Petition. Turning to factor (d), RavenWhite asserts that there is overlap between arguments that were presented during prosecution of the ’823 patent to distinguish the then-pending claims over Flash and the arguments presented in the Preliminary Response to distinguish the challenged claims over Hinton and Varghese. See Prelim. Resp. 25. This overlap, by itself, does not warrant discretionary denial because, as we explain below, Home Depot persuasively explains how the teachings of Hinton and Varghese account for the claimed “first client device browser storage area” and “second client device browser storage area.” See infra Section II.D.4.b and II.E.2.b.

However, we find that Dr. Brogioli provides sufficient persuasive evidence as to how firmware FRC logic would be used and modified in the Bigbee/Nguyen combination. See Ex. 1002 ¶¶ 57–58, 96–98. As discussed above, Bigbee uses firmware FRC logic to check for an error within a processor core. See Ex. 1005 ¶¶ 35–37, Fig. 4A.

In contrast, Patent Owner’s arguments fail to convince us that a person of ordinary skill in the art, having knowledge of Nguyen’s teaching of determining lockstep recovery, would not have able to modify Bigbee’s firmware FRC logic to determine if lockstep is recoverable. See KSR, 550 U.S. at 421 (“A person of ordinary skill is also a person of ordinary creativity, not an automaton.”); see also id. at 418. Accordingly, Petitioner has presented reasoning, with rational underpinnings, that a person of ordinary skill in the art would have had reasons to modify Bigbee’s firmware FRC logic based upon Nguyen’s teachings and would have had a reasonable expectation of success in doing so. Accordingly, we find for the reasons given that Petitioner demonstrates by a preponderance of the evidence that this element is taught or suggested by the Bigbee/Nguyen combination.” slip op. at 29

“particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (citing 35 U.S.C. § 312(a)(3) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”)); Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015) (discussing the burden of proof in inter partes review). A claim is unpatentable under 35 U.S.C. § 103 if “the differences between the subject matter sought to be patented and the prior art are such that the subject matter as a whole would have been obvious . . . to a person having ordinary skill in the art to which said subject matter pertains.” KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations, including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of skill in the art; and (4) when in evidence, objective indicia of non-obviousness.

“A Person of Ordinary Skill in The Art (“POSITA”) in Sept. 2007 would have had a working knowledge of network communications techniques and highspeed packet processing technologies. Ex.1003, ¶20. A POSITA would have had a bachelor’s degree in computer science, computer engineering, electrical engineering, or an equivalent training, and approximately two years of work experience in network communications. Lack of work experience can be remedied by additional education, and vice versa. Ex.1003, ¶20. Pet. 13. We use this definition for purposes of this Decision because it appears consistent with the level of skill reflected in the prior art and the ’471 patent.” slip op. at 6

“As to the claim requirement that the direct memory access device concurrently write the packet buffer memory and the protocol stack layer memory, Petitioner asserts that neither Cornett nor Paatela explicitly describes the timing of packet writing. Pet. 42. Petitioner asserts, however, that Nelson discloses writing a packet header separately and in parallel with writing the entire packet. Id. (citing Ex. 1006, 6:66–7:4; Ex. 1003 ¶ 89). Indeed, Nelson explains that the parallel storage action “avoid[s] having to read the frames out of the [larger frame] buffer” when reading a header, which eliminates the need for a separate reading step and “allows the routing decision to be made before the [frame] buffer becomes available.” Ex. 1006, 2:1–22 (containing the quoted language), 7:1–4 (describing “parallel . . . storage”). Petitioner asserts that it would have been obvious to write the packet header at the same time as writing the entire packet in Cornett, because Cornett, Paatela, and Nelson are concerned with speed, and writing in parallel would increase speed (vs. writing serially). Id. at 43–44 (citing Ex. 1003 ¶ 90); see also id. at 26 (similar argument). Reviewing Petitioner’s position with respect to independent claim 13, we determine that Petitioner has addressed each limitation in sufficient detail and with adequate citations to the record. Petitioner has also provided sufficient reasons for combining the teachings of Cornett, Paatela, and Nelson with a reasonable expectation of success. Reviewing the record before us, we determine that Petitioner has established a reasonable likelihood of success in showing that claim 13 would have been obvious in view of Cornett, Paatela, and Nelson.” slip op. at 11

“1. Means-Plus-Function Terms Challenged claim 26 recites elements using the word “means.” See Ex. 1001, 21:6–22:5. The use of the word “means” in a claim element creates a rebuttable presumption that 35 U.S.C. § 112 ¶ 6 applies.9 See Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015) (en banc in relevant part). Construing a means-plus-function claim term is a two-step process. We must first identify the claimed function. Then, we must determine what structure, if any, disclosed in the specification corresponds to the claimed function. Id. at 1351 (citation omitted). The parties do not dispute that 35 U.S.C. § 112 ¶ 6 applies to those “means” elements recited in claim 26. See Pet. 6–8; see generally Prelim.

“Petitioner argues that these terms “should be construed to include both mismatch errors and errors that may eventually result in mismatch errors constituting a ‘precursor to lockstep mismatch’—including at least one of (1) detecting a lockstep mismatch error; and (2) detecting an error that may eventually cause a lockstep mismatch error.” Pet. 6. Petitioner asserts that “[t]he specification provides detecting these two types of errors as examples of detection of LOL.” Id. (citing Ex. 1001, 2:40–3:6, 7:25–36; Brogioli Decl. ¶¶ 34–36). Petitioner further asserts that this construction “is consistent with the undisputed construction in the IPR challenging U.S. Patent No. 7,502,958.” Id. (citing BMW of N. Am., LLC v. Foras Techs.

Therefore, we determine that at this stage, we do not need to expressly construe these claim terms to resolve a controversy. 3. Summary and Conclusion For the reasons given, we determine that at this stage, we do not need expressly to construe any claim term for this Decision. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.
