In assessing the level of ordinary skill in the art, various factors 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.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

Based on the testimony of Mr. Crevelt, we determine that a person of ordinary skill in the art would have had at least a bachelor’s degree in computer science or computer engineering, with at least three years of experience in game development. Pet. 14 (citing Ex. 1003 ¶¶ 62–65). Additional experience could substitute for less education, and additional education could likewise substitute for less experience. Id. We determine that the level of ordinary skill in the art adopted above is consistent with the level of technical understanding and competence reflected in the ’336 patent Specification and the asserted prior art references, based on our review of the record. Patent Owner states that “[f]or the purposes of this response, Patent Owner does not dispute Petitioners’ proposed level of skill, and under any level of skill a POSITA would not understand the asserted Grounds to raise any unpatentability issue,” and “this POR and supporting declarations apply Petitioner’s proposed level of skill.” PO Resp. 8.

Petitioner only explains how the ’298PROV discloses “predetermined criteria” but does not provide any other explanation for how the other subject matter relied on in Walker is supported by the ’298PROV.

In its Reply, Petitioner does not dispute Patent Owner’s assertion, but merely reiterates its arguments from the Petition. See Reply 23–24, 26. However, none of these arguments or evidence demonstrates that the “game play events” in limitation 1[f] are same the “game play events” that are allegedly stored in limitation 1[d].

    “III. ANALYSIS LEVEL OF ORDINARY SKILL A. Petitioner explains the applicable level of skill in the art as follows: As of June 24, 2010, a person of ordinary skill in the art (POSITA) would be a person having a bachelor’s degree in computer science, computer engineering, or an equivalent, as well as two years of industry experience and who would have had a working knowledge of software security analysis, and dynamic malware analysis. Additional graduate education could substitute for professional experience, or significant experience in the field could substitute for formal education. Pet. 8 (Ex. 1003 ¶¶ 30–31). Patent Owner does not dispute Petitioner’s explanation of the level of skill in the art. See Ex. 2031 ¶¶ 15–16. We adopt Petitioner’s uncontested proposed level of ordinary skill in the art, which we find consistent with the level of ordinary skill in the art reflected by the ’872 patent and the prior art of record.

    “We begin with the claim language in view of the Specification, which weighs heavily against Patent Owner’s position that we should rewrite “computer system” as narrowly referring to a “computing device.” PO Resp. 24. As Petitioner notes, the ’872 patent’s Specification uses “computer system” to refer to a wide range of equipment, from a component of a computing device, to a whole computing device, to a collection of computing devices. Reply 9–10 (citing Ex. 1001, 4:5–8, 11:15–18, 16:50–55). In one example, the Specification refers to “one or more other computer systems (e.g., protected network devices 136).” Ex. 1001, 18:52–53. Thus, the Specification lists “protected network devices 136” as only an example of “other computer systems,” demonstrating that “computer systems” refers to things other than protected network devices. Although Patent Owner may be correct that this passage more than a single computing device,” we find that other disclosures in the ’872 patent do. Specifically, the Specification uses the language “distributed computer system” when referring to numerous components, including “protected network devices” and an “IDS/IPS system.” Ex. 1001, 3:26–28; Reply 10. In addition to showing that a “computer system” is not limited to a single computing device, this conveys that a “computer system” according to the ’872 patent can include an IDS/IPS.” slip op. at 14

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

    “Based on our review of the complete record, we find Petitioner’s arguments and evidence to be more persuasive. Patent Owner does not dispute Petitioner’s argument and evidence that capturing detailed information like Goel’s activity sources, activity targets, and association was recognized as enhancing threat analysis. Pet. 44 (citing Ex. 1003 ¶ 79); see PO Resp. 55–59; Sur-Reply 15–17. Additionally, contrary to Patent Owner’s suggestion, we find that the Petition does not propose incorporating Goel’s kernel hooks into Capalik’s system. See Pet. 41–46. Patent Owner contends that the Petition’s reference to modifying Capalik by “adding lines of code” suggests implementing the code disclosed in Goel include kernel hooks. Id. Notwithstanding Patent Owner’s assertion otherwise, this is an unpersuasive bodily incorporation argument, as the Petition never says an ordinarily skilled artisan would have used the exact lines of code from Goel in Capalik. Rather, the Petition says that an ordinarily skilled artisan would have had sufficient skill to implement straightforward code modifications to identify activity sources, targets, and associations: a [person of ordinary skill in the art] would have understood that modifying Capalik’s system (e.g., Linux-based) to additionally monitor, identify, and store each individual activity of an attack including “activity sources, activity targets, and associations” would have required straightforward modifications to programs/code instructions, which would have been well-within the skillset of a [person of ordinary skill in the art]. Pet. 46. Patent Owner argues that Petitioner does not explain how an ordinarily skilled artisan would have modified Capalik without using kernel hooks. Sur-Reply 17. But Patent Owner does not cite any evidence to counter Dr. Jakobsson’s testimony that an ordinarily skilled artisan would have had the skill to apply Goel’s general teaching of identifying sources, targets, and associations to Capalik’s system. Ex. 1003 ¶ 182. On the whole, the evidence does not support Patent Owner’s position that the combination would have required substantially increased detection risk. Moreover, even if the combination would have somewhat increased detection risk, Petitioner persuades us that an ordinarily skilled artisan still would have had reason to combine the references teachings. Patent Owner’s allegations of increased detection risk do not negate the undisputed evidence that the combination would have provided the advantage of improved threat analysis. Pet. 44 (citing Ex. 1003 ¶¶ 175–182). Ultimately, Patent Owner’s that activity logging be undetectable.” PO Resp. 56 (emphasis added) (citing Ex. 1004 ¶ 6). This exaggerates Capalik’s disclosure. Although the cited paragraph suggests that certain systems unfortunately may be detectable by some users, it does not convey that it is a requirement for the system to be categorically undetectable. See Ex. 1004 ¶ 6.8 In sum, Petitioner persuades us by a preponderance of the evidence that it would have been obvious to modify Capalik “to identify and store unauthorized activities including the activity source, activity target, and association of each activity.” Pet. 41–46; PO Resp. 55–59; Reply 20–22; Sur-Reply 15–17.” slip op. at 47

  • Obviousness (§103) › Objective indicia / secondary considerations › NexusObjective indicia no nexusDecided for patent owner

    “arguments and evidence, we determine that Patent Owner fails to sufficiently show a nexus between any of its objective indicia evidence and the claimed invention. See Fox Factory, Inc. v. SRAM, LLC, 944 F.3d 1366, 1373 (Fed. Cir. 2019) (“The patentee bears the burden of showing that a nexus exists”). A showing of sufficient nexus is required to establish that the evidence relied upon traces its basis to a novel element in the claim, not to something in the prior art. Institut Pasteur & Universite Pierre Et Marie Curie v. Focarino, 738 F.3d 1337, 1347 (Fed. Cir. 2013). Objective evidence that results from something that is not “both claimed and novel in the claim” lacks a nexus to the merits of the invention. In re Kao, 639 F.3d 1057, 1068 (Fed. Cir. 2011) (emphasis omitted). Thus, establishing nexus involves a showing that novel elements in the claim, not prior-art elements, account for the objective evidence of nonobviousness. Id. As discussed above, Petitioner shows that Capalik teaches all limitations of claim 1. Petitioner persuades us that none of claim 1’s elements individually nor any combination thereof is novel over Capalik’s disclosure. Accordingly, claim 1 is not novel over Capalik, which disproves Patent Owner’s assertion of nexus. PO Resp. 73–76. Moreover, even if claim 1 were novel, Patent Owner otherwise fails to show nexus for its commercial success, praise, or copying assertions. Patent Owner’s evidence does not show that Petitioner’s commercial product embodies claim 1. For example, we agree with Petitioner that Patent Owner “failed to analyze any meaningful detail regarding” how the Falcon Platform allegedly meets limitation 1(d). Reply 28–29. In particular, Patent Owner has not sufficiently addressed limitation 1(d) with the following argument: “1[D] The Falcon Platform transmitted to other computer systems” slip op. at 37

    “We find that Petitioner has shown that the combination of Doughty and Van Boucq accounts for these limitations. We are not persuaded by Patent Owner’s arguments that claim 1 somehow excludes, what Patent Owner calls, the “Unique Identifier/Tracker Embodiment.” See PO Resp. 27, 31. Beginning with the language of the claims, the claims are silent as to where the “location data” recited in limitation 1[c] is stored. See Tr. 21:7– 16 (Patent Owner agreeing that “the stored location data does not actually have a required location at all” in the claim, and need not be stored in a database). Nor does Patent Owner direct us to any claim language that would specifically exclude “location data” stored on the user’s device. See Sur-reply 2–3. “The patentee is free to choose a broad term and expect to obtain the full scope of its plain and ordinary meaning unless the patentee clearly redefines the term (lexicography) or disavows claim scope (claim disavowal).” Aortic Innovations LLC v.

Patent Owner directs us to statements in the Specification, stating “[f]or example, the computing device may access a database or other storage location that maintains a mapping of unique identifier to a browser session, a user computing device, and/or location data.” Ex. 1001, 9:52–55; see also id. at 39:26–30 (same), 43:55– 59 (same). But none of those passages amounts to lexicography or disavowal of claim scope. Indeed, when read in their full context, these passages support a broad reading, not a narrow reading, of the claims. The full passage of the Specification states: The computing device may determine, at 406, whether there is a unique identifier that is associated with the user (e.g., the user computing device, the browser, and/or the browser session) stored on the computing device. For example, the script may inform the computing device that there is no unique identifier for the user computing device. The computing device may determine that there is no unique identifier associated with the user computing device when there is no location data stored for the user computing device. For example, the computing device may access a database or other storage location that maintains a mapping of unique identifier to a browser session, a user computing device, and/or location data. Additionally or alternatively, the computing device may determine whether there is a unique identifier for associated with the user based on presence of a location tracker (e.g., cookie) installed in the browser application on the user computing device. Ex. 1001, 9:43–59. The passage above is full of language that indicates that the patentee did not intend to limit the claims to a single embodiment. Indeed, the specific portion of the passage cited by Patent Owner begins with “[f]or example” and further states “[a]dditionally or alternatively, the computing device may determine whether there is a unique identifier for associated with the user based on presence of a location tracker (e.g., cookie) installed in the browser application on the user computing device.” Id. at 9:52–59 (emphasis added). Moreover, the Specification states “[a]dditionally or alternatively, the computing device may determine the location data using the tracker installed in the browser application on the user computing device.” Id. at 10:2–5. The Specification also explains that the tracker may “maintain data related to the user and/or user computing device.” Id. at 12:62–63.

    “We find persuasive Petitioner’s reasoning that a POSITA would have been motivated to modify Doughty, based on Doughty’s own teachings regarding cookies and similar files, and would have recognized that the techniques of Van Boucq would have offered an efficient and commonly used way to determine whether the user already has been assigned a unique identifier. See Ex. 1007 ¶ 153. Patent Owner’s arguments about the precise contents of Van Boucq’s connection cookie attack Van Boucq individually and ignore the combination and modifications that Petitioner proposes. In the combination, Petitioner proposes incorporating the unique identifier from Doughty into Van Boucq’s connection cookie. See Pet. 26 (citing Ex. 1008, 16:59–17:33; Ex. 1007 ¶ 153).

Regardless of which definition of a POSITA were used, my conclusions would remain the same Ex. 2005, Bretschneider Decl., ¶ 39.

    “We find these definitions to be of some help in construing this term. We find that the common thread is that a “passivation layer” is an insulating layer that provides protection from the environment to the layers below it. See Ex. 1012, 140; Ex. 1013, 542, Ex. 1014, 798; Ex. 2010, 3; Ex. 2013, 1. We find this construction to be most consistent with the broad claim language and the disclosure in the Specification. Although “tying up dangling bonds,” may be a mechanism by which some materials provide such protection, nothing in the Specification or the extrinsic evidence provided appears to require that. Also, while chemical protection may be one kind of protection none of the evidence suggests that is the only protection that is provided. Moreover, nothing in the Specification supports reading a chemical protection requirement into the construction. Thus, we decline to adopt that portion of Patent Owner’s construction. Instead, we construe passivation layer as “an insulating layer that provides protection from the environment to the layers below it.” We need not construe the term any further to resolve the parties’ dispute over this claim language.

See Ex. 1002 ¶¶ 62–65. We further find that Petitioner has shown sufficiently that “first planarization film 17” is “formed over the entire surface for flattening, which will protect the semiconductor surface from the surrounding environment.” Id. ¶ 63. We have rejected Patent Owner’s contentions that the film must tie up “dangling bonds,” and instead determined that protecting the surface from the environment is sufficient. Thus, we find that Petitioner has shown by a preponderance of the evidence that Anzai discloses the “passivation layer” of claim 3. As we explained above, we have construed “capping layer” to be “an insulation layer covering (i.e., capping) an underlying layer or structure.” Here, Petitioner has shown that Anzai’s planarization film 19 meets the claimed “capping layer.” See Pet. 20. We find that Petitioner has shown that it is more likely than not that “planarization film 19” is made of insulating material.

While Anzai does not disclose the material for planarization layer 19, it must be made of an insulation material because in the embodiment of Fig. 3A, it is the sole layer between electrode layer 71 and cathode layer 65 forming the second capacitor. Id., 6:3–8; Fig. 3A. Moreover, Anzai discloses that the first planarization film 17 and the second planarization film 19 for the first embodiment “function as the capacitance insulating film for this configuration.” Id., 5:62–67. Ex. 1002, Neikirk Decl., ¶ 62. We find this testimony well-reasoned and entitled to substantial weight. We further agree with Dr. Neikirk that a “POSITA would further understand that the second planarization film 19 is then further disposed on the first planarization film 17 (capping the passivation layer).” Id. ¶ 63 (citing Ex. 1003, 5:3–13; Figs. 2A–B, 3A–B).

    “motivation to combine Anzai and Yamazaki. See Pet. 25–27; Ex. 1002, Neikirk Decl., ¶¶ 78–79. First, Patent Owner argues that essentially silicon nitride is an inferior material to use for Anzai’s planarization layer 17 compared with organic resin. PO Resp. 13–15. However, “[i]t’s not necessary to show that a combination is the best option, only that it be a suitable option.” Intel Corp. v. Qualcomm Inc., 21 F.4th 797, 800 (Fed. Cir. 2021) (emphasis in original). Patent Owner does not argue that silicon nitride would not work, but rather that it would be more difficult and more expensive to use. See PO Resp. 14. But “the fact that the two disclosed apparatus[es] would not be combined by businessmen for economic reasons is not the same as saying that it could not be done because skilled persons in the art felt that there was some technological incompatibility that prevented their combination. Only the latter is telling on the issue of nonobviousness.” Grit Energy Solutions LLC v. Oren Techs., LLC, 957 F.3d 1309, 1323 (Fed. Cir. 2020) (quoting Orthopedic Equip. Co., Inc. v. United States, 702 F.2d 1005, 1013 (Fed. Cir. 1983)). “Likewise, a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine.” Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006). Here, Petitioner explains that “a POSITA would have known that organic materials usually have lower dielectric constants than inorganic materials, such as SiN, and a higher dielectric constant is desirable for the insulator in a capacitor since that leads to higher capacitance per unit area.” Pet. 26 (citing Ex. 1002, Neikirk Decl., ¶ 78). Petitioner further explains that this “then allows a reduced area storage capacitance element, one of the objectives of Anzai.” Id. (citing Ex. 1003, code (57)). Patent Owner’s focus mainly on planarization (PO Sur-reply 16–17) ignores that the Anzai’s planarization layers 17 and 19 also “function as the capacitance insulating film.” Ex. 1003, 5:65–67. Thus, although there are tradeoffs, Petitioner has shown sufficiently that a POSITA would have been motivated to incorporate the teachings of Yamazaki regarding potential materials for planarization layers 17 and 19. Second, Patent Owner argues that a Petitioner has failed to provide an adequate reason to select silicon nitride from Yamazaki’s list of potential materials. We disagree. Petitioner has explained the benefits of selecting a high dielectric inorganic material. Pet. 26. Yamazaki provides only three potential options—silicon oxide, silicon nitride, and silicon oxynitride. See Ex. 1004, 11:45–50. Moreover, Dr. Neikirk testified, supported by multiple references, that using silicon nitride was well known in the prior art at the time of the invention. See Ex. 1002, Neikirk Decl., ¶ 75 (citing Ex. 1007; Ex. 1008; Ex. 1009). “When there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp.” KSR, 550 U.S. at 421. Indeed, “[i]f a person of ordinary skill can implement a predictable variation, § 103 likely bars its patentability.” Id. at 417. This is the case here. Petitioner has shown that a person of ordinary skill seeking to improve the capacitance of Anzai’s planarization layers 17 and 19, without increasing the size of the capacitor, would have looked at the inorganic materials identified in Yamazaki as suitable for the purpose, and it would have been would obvious to choose silicon nitride, a well-known, and predictable material for the application. Thus, we disagree with Patent Owner that Petitioner has failed to show a sufficient reason for selecting silicon nitride from Yamazaki’s list of suitable materials. Third, Patent Owner argues that Petitioner’s contentions only support” slip op. at 37

    “We disagree. Although claim 1 recites step 1b before step 1d, method steps are not ordinarily construed to require a specific order of performance unless the claims or Specification directly or implicitly require that specific order. See Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369–70 (Fed. Cir. 2003). Here, nothing in the express claim language precludes performing step 1d before step 1b. The claim does not expressly recite signaling the device(s) previously “identified as available.” Nor does the claim otherwise specify that step 1b must precede step 1d. For example, the claim does not contain temporal terms like “then,” “next,” or “further.” Although Patent Owner points out that a term of step 1d (i.e., “the” one more available devices) derives antecedent basis from step 1b, this alone does not require performing step 1b before step 1d. PO Resp. 5, 10; Sur-reply 11. Rather, we agree with Petitioner that step 1d’s reliance on step 1b for antecedent basis only serves to clarify that the steps refer to the same device(s), not to determine the performance order.

Missing in Zhang is an explicit teaching that its cellular calls (as opposed to other media) are routed. Pasanen explicitly teaches routing cellular calls to networked audio devices. Ex. 1006; 4:20–37. Taken together, routing Zhang’s cellular calls across its network would have been obvious to a POSITA. Patent Owner’s argument that Zhang-Fillebrown’s 802.11 or HomeRF network do not support routing cellular calls discounts Zhang’s teaching that “its network can be built on top of many different kinds of communication media” including but not limited to 802.11 and HomeRF, as well as the “optional HomeRF features” Petitioner claims would sufficient to implement the claimed functionality.

    “We find Patent Owner’s arguments unavailing. In particular, we find unavailing Patent Owner’s contention that “‘bus line 430’ is not an ‘auxiliary electrode’” (PO Resp. 28–33), because Patent Owner is relying on a claim construction of “auxiliary electrode” as precluding “essential” elements and requiring “more than the end structure of a conductor” (id.), that is not adopted by our construction discussed above. Here, we are persuaded by Petitioner’s reliance on Weaver’s bus line 430 for providing the claimed “electrode,” that is “supplemental to other electrodes in the structure.” Pet. 18; see also Ex. 1004 ¶ 26, Fig. 4; Ex. 1003 ¶ 92. We find availing Petitioner’s contention, supported by Dr. Baker’s testimony, that a POSITA would have understood that “anode 406 and bus line 430 are connected in parallel,” which means that “bus line 430 is a supplemental electrode that reduces the total resistance of the pixel structure.” Pet. 19; Ex. 1003 ¶ 94. Thus, we find availing Petitioner’s contention, supported by Dr. Baker’s testimony, that Weaver’s bus line 430 is an electrode supplemental to other electrodes in the structure that is electrically insulated from transistor 410 by passivation layer 409, wherein OLED 400, which includes cathode 422, organic layer 424, and anode 406, is disposed above bus line 430, and wherein anode 406 of OLED 400 is electrically connected to bus line 430 by via 428.

Reply 17–18 (citing Ex 1003 ¶ 157; Ex. 1020 ¶ 45). Further, contrary to Patent Owner’s contention that POSITA would not have combined Weaver with Lee ’053, Song, Lee ’149, or Bae without the use of hindsight (PO Resp. 33–45), as Petitioner points out, Lee ’149, for example, “explicitly teaches that ‘the electrode pattern 45 serves to lower the resistance of the first electrode 41.” Pet. Reply 58 (citing Ex. 1011 ¶ 38). Similarly, Bae “explicitly teaches that the “auxiliary electrodes 139 contact the first electrode 132 to commonly apply a voltage to the sub-pixels” and “reduces the resistance of the first electrode.” Id. at 66 (citing Ex. 1012 ¶¶ 37, 59). As such, Petitioner’s proposed combinations are supported by at least by Lee ’149’s and Bae’s teachings of applying a second electrode to lower the resistance and voltage drop between anode 406 and the VDD line of Weaver. See, e.g., Ex. 1011 ¶ 38; Ex. 1012 ¶¶ 37, 59. We are persuaded by Dr. Baker’s testimony that a POSITA would have understood that higher resistance between the power or ground line to the light emitting device would consume more power and require higher operating voltages, and thus, would have been motivated to implement the solutions of Lee ’053, Song, Lee ’149, or Bae to lower the resistance between anode 406 and voltage source VDD in Weaver. Ex. 1003 ¶¶ 145, 158, 184, 203. We agree with Petitioner, supported by Dr. Baker’s testimony, that a POSITA would have had a reasonable expectation of success the combining the references as suggested, wherein such modification “involves modifications of only routine skill in the art,” which “involve known method,” and “would have yielded predictable results. Pet. 42, 48–49, 59, 67–68; Ex. 1003 ¶¶ 145, 158, 184, 203.

    “The Federal Circuit found that “[t]he factual record and Willis’s concession on appeal conclusively establish that the cost of copper was a known problem in the art, Debladis ’120 (and Kumada) helped address that issue, and Willis has not disputed that combining the teachings of Kumada and Debladis ’120 was within the skill of an ordinary artisan,” concluding “[n]othing more is required to establish a motivation to combine.” Everstar II, 2025 WL 1501940, 4. The Federal Circuit observed that “Willis has conceded that the combination of Kumada and Debladis ’120 disclose all the limitations in claim 1,” and accordingly, “reverse[d] the Board’s patentability determination as to that claim and vacate[d] the Board’s judgment as to the remaining claims of the ’037 patent,” remanding to us for further proceedings. Id. at 4–5. With those instructions in mind, we review the Petitioner’s allegations regarding claims 2–33.” slip op. at 6

    “The parties agree that we do not need to construe any claim terms. Pet. 8–9; PO Resp. 16–17. We likewise agree. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed.

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

    “Patent Owner did not dispute that the combined teachings of Kumada and Debladis ’120 disclose each limitation of claim 1. Patent Owner, however, did dispute Petitioner’s proposed reasons for combining Kumada and Debladis ’120, and argues that Debladis ’120 is not analogous art. PO Resp. 36–61. The Federal Circuit stated that substantial evidence only supports the conclusion that a POSA would have been motivated to combine the teachings of Kumada and Debladis ’120. The factual record and Willis’s concession on appeal conclusively establish that the cost of copper was a known problem in the art, Debladis ’120 (and Kumada) helped address that issue, and Willis has not disputed that combining the teachings of Kumada and Debladis ’120 was within the skill of an ordinary artisan. Nothing more is required to establish a motivation to combine. Given that Willis has conceded that the combination of Kumada and Debladis ’120 disclose all the limitations in claim 1, we reverse the Board’s patentability determination as to that claim and vacate the Board’s judgment as to the remaining claims of the ’037 patent. Everstar II, 2025 WL 1501940, 4 (internal citations omitted). The Federal Circuit further noted Patent Owner’s secondary considerations arguments as to claim 1 and stated [t]he cited evidence consists only of a temporal connection between the introduction of Willis’s invention and the UL 588 standards, and deposition testimony of a single witness who seemingly disclaimed any connection between the two. This is not sufficient to rescue a claim as to secondary considerations. Id. at 4, n. 5 (internal citations omitted). Accordingly, the Federal Circuit ruled that claim 1 would have been obvious over Kumada and Debladis ’120. 6. Analysis of Independent Claim 33” slip op. at 17
