According to Petitioner, Jaye “recognizes the importance of collecting profile information for targeted advertising” and discloses “techniques for combining profile information from multiple local websites visited by users into more comprehensive global profiles that may be shared with ‘interested outside parties, such as advertisers.’” Id. at 21 (citing Ex. 1005, code (57), 1:18–38, 2:6–10, 2:6–8, 2:15–3:40, 5:5–19, 6:1– 7:45, 8:40–10:41,14:22–25; Ex. 1002 ¶ 123). Petitioner contends that a person of ordinary skill in the art would have been motivated to “incorporate Jaye’s techniques for collecting and combining profile information to enhance and improve Meriman061’s ad targeting by providing more information about the users to whom the ads are targeted.” Id. (citing Ex. 1002 ¶ 123). Having reviewed the arguments and evidence included in the Petition, including the Houh Declaration, which are not substantively addressed by Patent Owner at this stage, we are persuaded that Petitioner sufficiently demonstrates, for purposes of this Decision, that it would have been obvious to combine Merriman061 and Jaye in the manner set forth in the Petition.” slip op. at 26

“and “how” the references would have been combined. As the Petition explains, Krummacher discloses radiation scattering particles having a size range of 50 to 1000 nm. See Pet. 26 (citing Ex. 1107 ¶ 39). Petitioner further explains that a person of ordinary skill in the art would use Stokes teachings to further refine that size range to optimize the particle size to preferentially scatter blue light. See id. at 26–27. Petitioner further provides reasons, suggested in Stokes itself, why a person of ordinary skill would have made this modification to Krummacher. See id. at 27–28 (citing Ex. 1108, 7:17–26; Ex. 1102 ¶ 128). Petitioner provides sufficient evidence that such a particle size selection was within the level of skill in the art at the time of the invention. See Ex. 1102 ¶¶ 122–128, 140–144; Ex. 1108, 7:1– 17; Ex. 1124 ¶¶ 80–81. We note that we have reviewed the testimony of Patent Owner’s expert, Dr. Schubert, but this testimony does not, at this stage, diminish the weight we give to Petitioner’s expert. Thus, we find that Petitioner has shown sufficiently that the combination of Krummacher and Stokes accounts for this limitation and that a person of ordinary skill would have combined the references in the manner suggested with a reasonable expectation of success.” slip op. at 23

“In our Institution Decision in IPR2024-01357, we analyzed claim 1 of the ’678 patent in light of Basin-2007 and Basin-2005. ’1357 IPR, Paper 17, 23–28. We concluded, after reviewing the arguments presented there, that “Petitioner has demonstrated a reasonable likelihood of proving that the combined teachings of Basin-2005 and Basin-2007 render claim 1 unpatentable as obvious.” Id. at 28. In this proceeding, Petitioner has presented a challenge to claim 1 based on those same references that it represents is a “verbatim” copy of its previous challenge to claim 1 in the ’1357 IPR. Pet. 1–2, 28–35. Petitioner supports its challenge with expert testimony. Ex. 1002 ¶¶ 107–125.7 Patent Owner has not submitted a response on the merits of this challenge. For the purposes of this Decision, and for the reasons given in the Petition, we adopt the analysis in our Institution Decision in the ’1357 IPR (at pp. 23–28), where we determined that Petitioner has demonstrated a reasonable likelihood of prevailing on its obviousness challenge to claim 1 based on Basin-2005 and Basin-2007. Turning now to Petitioner’s challenge to claim 11, Petitioner relies on Basin-2007 and Stokes for the particle size limitations added to claim 1 by that dependent claim. Pet. 35–39. Thus, Petitioner asserts that “Basin-2007 discloses a light scattering material with an average TiO2 particle size that is ‘sub-micron’ (less than 1000 nm).” Id. at 37 (citing Ex. 1005 ¶ 5). 7 Exhibit 1002 appears to be a duplicate copy of Dr. Doolittle’s declaration from the ’1357 IPR. Petitioner concludes, “Basin-2007 renders obvious claim 11 by literally disclosing the selection of average particle sizes that preferentially scatter blue light.” Id. Further, “to the extent that the claim language ‘an average particle size that is selected such that [it preferentially scatters blue light]’ requires an average particle size selected for that reason (rather than an average particle size that leads to that outcome), this claim element is rendered obvious by Stokes.” Id. at 38 (citing Doolittle Decl. ¶ 45) (alterations in original). Petitioner explains that “Stokes explicitly discloses the selection of an average particle size ‘such that the particles preferentially scatter blue . . . LED light as compared to yellow . . . light from the luminescent material.’” Id. at 38 (citing Ex. 1008, 7:1–4) (alterations in original). Petitioner provides a motivation for combining Stokes with Basin- 2007 with a reasonable expectation of success. Pet. 38–39. Petitioner explains that “[t]o the extent that claim 11 is understood to also claim the basis for selecting a particular average particle size, a [person of ordinary skill] would have had reason to use such a basis for selecting average particle size as taught by Stokes.” Id. at 38 (citing Doolittle Decl. ¶¶ 46–48). Further, “a [person of ordinary skill] would have been motivated to apply this principle to Basin-2007, because it would increase the conversion of blue light to yellow light and improve the uniformity of the light source.” Id. at 39 (citing Doolittle Decl. ¶ 48).

Users in Fuloria may like a piece of content or “for a given price” the user may turn their like into a “super-like.” Id. ¶ 37. “The ‘super-liked’ story is priced and directed toward users in a similar manner as a social ad. In particular embodiments, sponsored story system 304 may also add a weight to the story to alter its direction toward users.” Id. ¶ 39. Petitioner argues that “[t]his functionality represents uncapped engagement . . . because Fuloria places no limitation on how many times a user can super-like a piece of content.” Pet. 24–25. Dr. Bederson supports Petitioner by noting that Fuloria does not “place any limitation on how many credits a user can spend to increase the reach of the content.” Ex. 1002 ¶ 76. Further, Dr. Bederson states that “[m]ultiple different users can also promote the same content item. By allowing users to promote or ‘super-like’ content which also increases engagement with that content by other users, Fuloria’s system also facilitat[es] uncapped engagement with that content.” Id. ¶77. We find these arguments to be persuasive. The ’687 patent states that “[s]o long as the user has sufficient resources, the user may promote herself or others with uncapped (i.e., unlimited) engagements, which may facilitate getting noticed by other users, whether with respect to a social media content item.” Ex. 1001, 2:6–10.

“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.

“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.
