      “We regarded Petitioner’s description as consistent with the prior art before us. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself may reflect an appropriate level of skill). Thus, for the purpose of our Institution Decision, we adopted Petitioner’s proposal. Institution Dec. 8–9. In its Response, Patent Owner does not take exception to our definition. See PO Resp. 3. However, Patent Owner asserts that a person of ordinary skill in the art “would have the equivalent of a bachelor’s degree in Computer Science, Computer Engineering (or a related field) and approximately two years of work experience with computer architecture design.” Id. We find Patent Owner’s and Petitioner’s definitions of a person of ordinary skill in the art are not meaningfully distinguishable from one another. Accordingly, we do not see the need to modify our adoption of Petitioner’s proposed level of ordinary skill in the art. However, our findings would not change even under Patent Owner’s proposed level of skill in the art.” slip op. at 13

      “We are satisfied that Mr. Jones qualifies as a person of ordinary skill in the art. See, e.g., Ex. 2008, 1 (“Summary” including “embedded systems including both software and hardware”, “Representative Design Work” including, e.g., “Design and implement multiple device drivers for complex Integrated circuits,” “Design of a highly fault tolerant, distributed data acquisition and control, system for a rebreather . . . system architecture, hardware design and layout, embedded firmware, documentation,” “hardware and firmware design,” “[h]ardware and firmware for controlling a unique, battery powered diesel burner…”), 2–3 (list of Publications). We are also satisfied that Mr. Jones’ degree in Electrical and Mechanical Engineering is sufficiently “equivalent” to a degree in Computer Engineering or Computer Science. See PO Sur-reply 11. We decline to give Mr. Jones’ declaration no weight for several additional reasons. One, Petitioner has not moved or otherwise sought to exclude Mr. Jones’ declaration, nor has Petitioner filed an objection. See Pet. Reply 2–5; see also Hearing Tr. 32, 33:15–34:8. Two, we are afforded broad discretion in assigning weight that is to be accorded expert testimony. See Yorkey v. Diab, 601 F.3d 1279, 1284 (Fed. Cir. 2010) (“[T]he Board was well within its discretion to give more credibility to [one expert over another] unless no reasonable trier of fact could have done so.”); see also CTPG5 34–36. In sum, Petitioner has not persuaded us that Patent Owner’s expert’s testimony should be given no weight because Mr. Jones is not qualified as a person of ordinary skill in the art according to our definition. See Pet. Reply 2–5; see also PO Sur-reply 10–13. 5 Patent Trial and Appeal Board Consolidated Trial Practice Guide (CTPG) (Nov. 2019) (available at https://www.uspto.gov/TrialPracticeGuideConsolidated).” slip op. at 14

      “Patent Owner did not challenge Petitioner’s position on these terms. See Prelim. Resp. 1–13. We determined there were no claim terms that needed to be construed in our Institution Decision. See Institution Dec. 9– 10. Post-institution, Patent Owner does not dispute Petitioner’s construction of these terms and “does not believe either term requires construction, because . . . Petitioner fails to demonstrate obviousness regardless of how these terms [(“lockstep is recoverable” and “loss of lockstep is recoverable”)] are construed. PO Resp. 2. We agree with Patent Owner that no claim construction is necessary for purposes of this Decision. That is, we do not discern any claim terms that are in controversy on the full record. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

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

      “We find Mr. Jones’ testimony amounts to conjecture because it is unsupported by evidence, for the reasons explained by Petitioner. See Pet. Reply 10–11; Ex. 2007 ¶ 32; see 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”). 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. Bigbee’s firmware FRC logic does not determine if lockstep is recoverable. Id. Similar to Bigbee, Nguyen also uses firmware FRC logic to check for an error within a processor core. See Ex. 1006 ¶¶ 9, 18, Fig. 7. However, the difference is that Nguyen’s firmware FRC logic determines if lockstep is recoverable. Id. We find for the reasons given by Petitioner and Dr. Brogioli including those summarized supra, that it would have been obvious to one of ordinary skill in the art to modify Bigbee by implementing Nguyen’s determination in firmware. Pet. 33–35 (citing, e.g., Ex. 1002 ¶ 94 (stating that “[i]mplementing logical steps in firmware was known in the art”); ¶ 95 (stating that Bigbee’s system “is compliant with well-known industry standards”); ¶ 98 (stating that “firmware is flexible” and “can be modified after production, updated, and supported relatively quickly and inexpensively.”)). 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

      “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

      “Motivation to Combine Fox, Safford, and Arai and Fox, Safford, Landry, and Arai Petitioner asserts that a person of ordinary skill “would have found it obvious to combine Fox’s multiprocessor system with Safford’s lockstep processor and error detection logics and Arai’s processor-switching implementation details.” Pet. 10. Dr. Brogioli testifies that “[a person of ordinary skill] would have been motivated to implement the processors in Fox as lockstep processors to improve reliability and availability of Fox’s server system for critical processes, for which higher reliability and availability of the system are desired.” Brogioli Decl. ¶ 90. He further testifies that “[a person or ordinary skill] also would have been motivated to implement in Fox the error detection logics that detect loss of lockstep together with the lockstep processors as taught by Safford to implement lockstep functions and further improve availability of the system.” Id. He testifies that “[a person of ordinary skill] would have understood how to implement Fox’s processors as lockstep processors with error detection logics and expect success. [A person of ordinary skill] would only have applied well-known configurations and ordinary hardware and software configuration skills.” Id. ¶ 91. Dr. Brogioli provides additional reasons motivating the combination. Id. ¶¶ 92–99. Petitioner contends that “Arai discloses switching the role of a failing processor with a spare processor.” Pet. 10. Dr. Brogioli testifies that “[a person of ordinary skill] would have been motivated to incorporate Arai’s teaching of transferring processor context from the failing processor to the spare processor not to interrupt the operating system and its running applications as desired by Fox.” Brogioli Decl. ¶ 109. He reasons that “[a person of ordinary skill] would have understood that incorporating Arai’s benefit of switching the role of the failing processor to the spare processor without affecting the operating system and running applications, which is expressly taught as desirable by both Fox and Arai and well known in the art.” Id. ¶ 110. Petitioner asserts that a person of ordinary skill also would have been motivated to further combine these references with Landry. Pet. 33–35. Dr. Brogioli testifies that “Landry discloses a fault-tolerant boot process that dynamically designates a functional CPU as logical CPU0 that performs the unique functions of a boot processor.” Brogioli Decl. ¶ 147. He testifies further that “[a person of ordinary skill] would have understood Landry’s process would have been a suitable option for selecting a boot processor in Fox’s system consistent with the initialization protocol of the IA-32 multiprocessor system.” Id. He asserts that “[a person of ordinary skill] would have understood the benefits of implementing Landry’s boot processor selection process in Fox.” Id. ¶ 148. Among other reasons, “[a person of ordinary skill] would have further understood that using the logical CPU0 as the identification for the boot processor allows for transparent replacement of the physical processor experiencing a failure with another processor without interrupting the operating system.” Id. At this stage, Patent Owner does not respond to these arguments by Petitioner or refute the testimony by Dr. Brogioli. On this record, we find that Petitioner has sufficiently demonstrated a motivation to combine Fox and Safford with Arai and to further combine these references with Landry with a reasonable expectation of success.” slip op. at 29

      “prevail in showing that it would have been obvious to use blue light with a wavelength that is greater than 440 nm. Basin-2007 does not specify a specific wavelength for the blue light, but, as Patent Owner acknowledges, “blue light is generally emitted in the range of 380 to 500 nm.” Prelim. Resp. 55; see Ex. 1002 ¶ 121. Thus, the question is whether a skilled artisan, when looking for which wavelength to use, would have found it obvious to use anything in the half of the blue-light range that is greater than or equal to 440 nm. On its own, this overlap in ranges would be strong evidence of obviousness. See Galderma Lab’ys, L.P. v. Tolmar, Inc., 737 F.3d 731, 738 (Fed. Cir. 2013). Petitioners show even more. Basin-2005 discloses that there is an “assum[ption]” that blue-light LEDs emit “in the range of 420-490 nm.” Ex. 1006 ¶ 30 (cited in Pet. 25). Basin-2005 additionally teaches that its “blue, UV, or near UV LED[s]” are “relatively easy to implement and consistently produce[] the desired white light temperature.” Id. ¶ 6 (cited in Pet. 25). Furthermore, Shimizu and Stokes indicate that people were using higher wavelength blue-light in their LEDs. See Pet. 8, 24–25 (citing sources). Because a skilled artisan would have needed to select some wavelength for the blue light disclosed in Basin-2007, at this stage, we conclude that the skilled artisan would have found it obvious to include wavelengths from the higher end of the range—as disclosed in so many references. Basin-2007 discloses using a “conventional white light LED.” See Ex. 1005 ¶ 21. As evidenced by Shimizu and Stokes, the conventional white light LED sources used blue light with wavelengths greater than or equal to 440 nm. See Ex. 1002 ¶ 121 (citing sources). Patent Owner argues that “quantum efficiency” considerations would lead to using lower wavelengths, but Patent Owner does not explain why these same considerations did not convince Basin-2005, Shimizu, or Stokes to use lower wavelengths. Based on our review of the current record, we find 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.” slip op. at 27

With respect to the second issue, institution generally will be denied if a “petitioner fails to make a showing of material error,” and “[i]f reasonable minds can disagree regarding the purported treatment of the art or arguments, it cannot be said that the Office erred in a manner material to patentability.” Id. at 8–9. “[T]his framework reflects a commitment to defer to previous Office evaluations of the evidence of record unless material error is shown.” Id. at 9.” slip op. at 29

      “2. Reasons to Combine Shiplacoff and Nan Petitioner contends that a person of ordinary skill in the art would have implemented the touch gestures of Nan in Shiplacoff’s device that includes a touch screen for the benefits of avoiding latency and not displaying on-screen controls. Pet. 43–44. Petitioner contends that using the gestures of Nan, which include factors such as length, speed, hold time, and number of fingers, to execute a change from one of Shiplacoff’s display modes to another, does no more than yield predictable results. Id. at 43, 45. We are sufficiently persuaded that Petitioner has shown a reason to use the edge gestures of Nan to switch from one of Shiplacoff’s display screens to another.” slip op. at 26

Prelim. Resp. 32–33 & n.4. On the present record, Petitioner’s proposed construction appears correct, and for purposes of institution, we apply this proposed construction of “a magnitude of the blurring” as discussed below in our analysis of limitation [1.d.ii]; the construction of this term may be addressed by the parties as this inter partes review proceeds.” slip op. at 9

      “Patent Owner contends that “Petitioner’s alleged motivation for modifying Ramos’ Zlider to be transparent is superficial and conclusory.” Prelim. Resp. 24; see generally Prelim. Resp. 24–26. As noted above, Petitioner relies on evidence from Ording itself and Dr. Cockburn’s testimony that relies on evidence to support its conclusion. Thus, we do not agree with Patent Owner that Petitioner’s motivation is insufficient for institution. Patent Owner also argues, relying on Dr. Davis’ declaration testimony, that the Vernier on a semitransparent Zlider widget would be “completely illegible” in some circumstances “rendering the very core of Ramos’ work unusable.” Prelim. Resp. 24–25 (citing Ex. 2001 ¶ 88); see Ex. 2001 ¶ 88 (not adding reasoning or evidence beyond that in the Patent Owner Preliminary Response). On this preliminary record, it would appear that when the Zlider widget and the portion of the image underlying the Zlider widget are the same color, the semitransparent Zlider widget may not work as well as when the Zlider widget and the underlying image are different colors. That does not outweigh, for purposes of determining whether to institute trial, the prior art evidence that Petitioner offers of the from Ording and other prior art references on which Dr. Cockburn’s declaration testimony relies. Ex. 1003 ¶ 66 (citing Ex. 1025 ¶¶ 77, 94, 101; Ex. 1026 ¶¶ 153, 162); see Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 799– 800 (Fed. Cir. 2021) (determining that a showing of the obviousness in predictable use of prior art elements according to their established functions requires only a showing that the combination be a suitable option, rather than a showing that it is the best option). Petitioner also contends, relying on declaration testimony from Dr. Cockburn, that one of ordinary skill would have had a reasonable expectation of success in combining the references in the manner proposed by Petitioner. Pet. 33–34. Petitioner contends that implementing the Zlider widget “described in the Ramos Paper and Ramos Video in a device, as taught by Ording, would have required only routine knowledge well within the skill of a POSITA” and would involve “combining prior art elements according to known methods to yield the predictable results” described by Petitioner’s proposed combination of the references.

      “On this record, we preliminarily agree with Petitioner that the claim limitations amount to a combination of known elements that a POSITA could have combined to achieve predictable results. See Intel, 21 F.4th at 799–800 (determining that a showing of the obviousness in predictable use of prior art elements according to their established functions requires only a showing that the combination be a suitable option). Among other reasons, the preliminary record supports Petitioner’s arguments that combining the teachings of Blumenberg, Bhumkar, and Griffin amounts to applying known solutions in the field of computer interfaces with predictable outcomes. See Pet. 12–18. As noted above, we encourage the parties to address the scope and meaning of the “when” limitations as a matter of claim interpretation, but we do not currently understand the plain language of Limitation [1.o] to require that the “portion of the second web page” or “menu” is displayed only after expiration of the “second user-configurable predefined duration,” termed by Patent Owner the “Alternative Modification.” Again, we encourage the parties to fully address this issue as a matter of claim construction. We additionally note that, even if we were to interpret the claims to require that the recited functions of Limitation [1.o] occur only the “prerequisite elements” are satisfied, we are still preliminarily persuaded by Petitioner’s arguments that combined teachings of the prior art satisfy the claim elements as a mere combination of known elements combined according to their known functions with predictable results.” slip op. at 27

      “scenarios.

Resp. 3 (“With respect to claim 1, these three scenarios include: . . . .”); see Ex. 2001 ¶¶ 28 (“As recited in claim 1, the three different claimed functionalities are executed ‘when’ the prerequisite elements are met (described as three scenarios by Dr. Cockburn.”) (citing Ex. 1001, 102:50–103:55; Ex. 1003 ¶¶ 33–35), 29–32 (describing the first, second, and third scenarios). In substance, the parties’ dispute appears to concern whether the plain language of the claims requires that a recited function must be performed only after or in response to expiration of a threshold (and other prerequisites), as opposed to requiring a function that begins before and continues after expiration of a threshold. Notably, dependent claim 3 recites: “The electronic device of claim 1, wherein the electronic device is configured such that the first feedback that is perceptible by touch is output prior to the display of the menu.” Ex. 1001, 104:1–4 (emphasis added). Given that independent claim 1 is necessarily broad enough to include claim 3, it seems on this record that the functions recited in Limitation [1.o] necessarily can happen at different times, as opposed to, for example, only responses that are triggered by the so-called “prerequisite elements.” We encourage the parties to address this issue as a matter of claim interpretation in future briefing. Based on the current record, however, we determine that it is not necessary to provide an express interpretation of any claim terms at this stage of the proceeding. See Realtime Data, LLC v. Iancu, 912 F.3d 1368 (Fed.

After considering Hotelling and the parties’ arguments and testimony, we determine that, on the present record, Petitioner has sufficiently shown that Hotelling’s general teachings regarding gestures received on a touch screen includes the recognition of touch gestures (pressing a button, sliding a finger or stylus, moving the entire device spatially) while Hotelling’s main page is being displayed.
