    “We find insufficient support in the specification or prosecution history to narrow the term “haptic effect” to only one that has not been modified or combined with another haptic effect. The ’738 patent still refers to combined or modified haptic effects as a “haptic effect.” Ex. 1001, 11:35–38 (“a haptic effect may further be modified or combined with another haptic effect” and “the haptic effect can include one or more haptic effects”). We also find no support for importing into the construction of “haptic effect” the ’738 patent’s example in which a haptic effect can be “based on the proximity signal and the touch sensor signal.” That is already an explicit claim limitation. Id. at 14:19–20 (“generate a haptic output signal based at least in part on the first [proximity] and second [touch] sensor signals”). Including that limitation as part of the construction of “haptic effect” would render the limitation superfluous. See Apple, Inc. v. Ameranth, Inc., 842 F.3d 1229, 1237 (Fed. Cir. 2016) (“The Board was correct to not include in its construction of ‘menu’ features of menus that are expressly recited in the claims . . . . Construing a claim term to include features of that term already recited in the claims would make those expressly recited features redundant.”). We also disagree with Patent Owner that the ’738 patent’s references to haptic effects modified or combined with other haptic effects are unclaimed embodiments. The ’738 patent discloses that a proximity-based haptic effect may be combined with a touch-based haptic effect, such as when “a particular haptic effect associated with a particular control on a user interface element [is] further . . . modified or combined with another haptic effect based on the proximity sensor signal,” or when “the haptic effect [to be output by the processor] . . . include[s] a haptic effect meant to confirm ‘pushing’ on a virtual button.” Ex. 1001, 11:32–40. These examples are consistent with the claim language and we find no credible evidence in the record that these embodiments are intended to be excluded from the claimed invention. Thus, we agree with Petitioner that it would be incorrect to construe the term “haptic effect” to include the extraneous limitations Patent Owner proposes. We also agree with Petitioner that a person of ordinary skill in the art reading the ’738 patent disclosure would have understood that a combined or modified haptic effect is still a haptic effect.” slip op. at 11

    “We find Petitioner’s arguments persuasive and disagree with Patent Owner’s arguments to the contrary. Ku discloses summing two overlapping vibration signals, one “based at least in part on” data from a proximity sensor and another “based at least in part on” data from a touch sensor. Ex. 1008, Fig. 12 (items 705, 710, and 715). The summed signal 715 is the basis for generating what the user would perceive as a single haptic effect. See Ex. 1004 ¶ 210–212. This meets limitation 1F. We agree with Petitioner’s argument as to why there would have been a motivation to modify Pratt to include Ku’s teachings. Petitioner’s argument is not merely that Pratt was ready for improvement; Petitioner persuasively argues that a person of ordinary skill in the art would have had reason to add Ku’s method for confirming that the user has touched the intended icon to Pratt’s system. Both Pratt and Ku already disclose using both proximity and touch data in generating a haptic effect, and based on the evidence of record, we are of the view that combining the two teachings would not have been uniquely challenging or otherwise beyond the level of ordinary skill in the art.

However, Patent Owner does not provide a specific number of years of industry experience and Patent Owner would include mixed-signal IC design as an alternative to analog circuit design. We consider analog circuit design to be most pertinent to the problems and solution discussed in the ’074 patent. See Ex. 1001, 1:15–2:44. In addition, we find credible Petitioner’s argument that an ordinarily skilled artisan with a bachelor’s degree would have had two years of experience, whereas Patent Owner’s proposal does not provide a specific number of years.

    “We agree with Petitioner that “gm boosting” is the only gm enhancement referred to in the ’074 patent, that the ’074 patent uses the terms “gm enhanced” and “gm-boost” synonymously, and that Patent Owner has failed to point to any credible intrinsic evidence of this alleged distinction. Although, “[i]n the absence of any evidence to the contrary, we must presume that the use of . . . different terms in the claims connotes different meanings, CAE Screenplates Inc. v. Heinrich Fiedler GmbH, 224 F.3d 1308, 1317 (Fed. Cir. 2000), in this case there is evidence to the contrary. In particular, the ’074 patent never refers to “gm enhancement” as a function separate from “gm boosting.” Indeed, the transistors (368, 370, and 382) that Patent Owner identifies as performing the function of “gm enhancement” are disclosed as part of a “gm-boost stage.” Ex. 1001, 5:8–24. Patent Owner’s alleged separation of Figure 3B into distinct “gm boosting” and “gm enhancement” is not consistent with the intrinsic evidence and is based on the conclusory testimony of Dr. Taylor. Thus, based on the evidence of record, we disagree with Patent Owner’s proposed construction distinguishing the terms “gm enhanced” and “gm-boost” in claim 1. Rather, we find persuasive Petitioner’s argument that a person of ordinary skill in the art would have regarded these terms to be synonymous. We need not otherwise construe these two terms to resolve the contested issues in this proceeding. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

    “Looking first at the claim language itself, Patent Owner’s construction is unduly narrow. The “for” recitations derive antecedent basis from limitation 4a. Ex. 1001, 36:44–45. Limitation 4a recites “a 4-step” procedure and “a 2-step” procedure. Thus, the claim includes one of each procedure type: “one” 4-step and “one” 2-step (i.e., single instances of each procedure). Patent Owner similarly reads the claim as requiring “one or more” of each procedure type. See Tr. 33:19–34:4. Because limitation 4a provides antecedent basis for a singular 4-step procedure and a singular 2-step procedure, this strongly suggests that the claim requires for the one (or for the single) 4-step procedure but not for all 4-step procedures, and for the one (or for the single) 2-step procedure but not for all 2-step procedures. At trial, Patent Owner’s interpretation was similar, stating, “that would read. . . as for the one or more 4-step . . . procedure and for the one or more 2-step . . . procedure.” See Tr. 33:25– 34:4 (emphasis added). In seeming contradiction, Patent Owner also stated, “I read that as being . . . all 4-step contention random access procedures . . . and all 2-step random access based procedures.” Id. (emphasis added). We note that Patent Owner does not, however, cite any legal precedent for interpreting “one or more” as requiring “all,” or provide reasoning for departing from the default claim construction principle that “one or more” includes “one.” For this reason and for reasons further discussed below, construing “for the 4-step” to mean “for all 4-step,” and “for the 2-step” to mean “for all 2-step,” would improperly import limitations from the Specification into the claims. See SuperGuide Corp. v. DirecTV Enters., Inc., 358 F.3d 870, 875 (Fed.

    “With these teachings in mind, we are persuaded by Petitioner that incorporating Lee2’s higher power and different ramping into Lee1’s 2-step procedure would have even further reduced the latency of Lee1’s 2-step procedure, and that this would have resulted in different power settings based on procedure type. Pet. 37–38; Ex. 1003 ¶¶ 88–89; Reply 12–13. Patent Owner does not meaningfully dispute this point. See generally PO Resp. 37–42; Sur-reply 12–17.

See PO Resp. 41–42. However, Petitioner’s burden is to provide a motivation for the proposed combination—in this case, modifying Lee1’s 2-step procedure with Lee2’s higher power and lower ramping. The obviousness analysis does not require Petitioner to explain why the references would not have been combined in an alternative way not proposed by Petitioner.

    “inside” it, the evidence does not support Patent Owner’s position. First, the plain language of independent claim 1 states that the proxy object “compris[es]” the one or more haptic output devices. Ex. 1001, 10:42–43. This is broader than the “within” language of the non-entered amendment. See Ex. 1002, 258. Not only does the evidence fail to show clear disclaimer (see United States v. Telectronics, Inc., 857 F.2d 778, 782–83 (Fed. Cir. 1988)), the adoption of broader “comprising” language shows an intent for the claims not to be limited to systems in which the proxy object contains haptic output devices “inside” it. We also do not agree with Patent Owner that the applicant’s attempts during prosecution to distinguish Gonzales are a clear disclaimer of claim scope. The applicant argued that Gonzales’s AR glove, which contained haptic output actuators in it (see, e.g., Ex. 1008 ¶¶ 80–82, Fig. 3B), was not a “proxy object” as recited in the claims because “the virtual objects and/or visible alterations to the vehicle [the user is sitting in while wearing the 6 Once again, Patent Owner mistakenly references Exhibit 2001. glove] are not overlaid on the AR glove . . . [a]nd the physical portions of the vehicle were visible alterations are overlaid do not include any feedback devices.” Ex. 1002, 287. Thus, the issue raised during prosecution was not whether the AR glove comprised haptic output devices—which it clearly did even under Patent Owner’s proposed construction—but whether the AR glove had modified visual effects displayed on it as per limitation 1D3. slip op. at 11

    “Petitioner argues that a person of ordinary skill in the art “would have a bachelor’s degree in electrical engineering, computer science, or a related field, plus at least two years of industry experience or graduate-level academic experience with human-computer interaction.” Pet. 7 (citing Ex. 1003 ¶¶ 40–45).

We agree with Petitioner that, for this Decision, we do not need to construe any of the terms explicitly. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

    “A claim is unpatentable for obviousness under § 103(a) if the differences between the claimed subject matter and the prior art are “such that the subject matter as a whole would have been obvious at the time the invention was made 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).

We base our obviousness inquiry on factual considerations 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) any objective indicia of obviousness or non-obviousness that may be in evidence.4 See Graham, 383 U.S. at 17–18.” slip op. at 7

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Plain and ordinary meaningOther

    “As we explained in the Institution Decision, we have reviewed the Board’s prior decision in IPR2016-01777 and we disagree with Valve that the previous Board panel actually construed the “determining a press” limitation. See Dec. on Inst. 9–10. The previous Board panel was merely making the point that the three conditions in the “determining a press” limitation had to be related in some way, and pointed to Figure 3 of the ’507 patent as an example of that relationship. IPR2016-01777, Paper 7 at 14–15 (Ex. 1023) (explaining that the interval in Figure 3 is “an integral part of the ‘determining a press imitation’”). The prior Board decision in IPR2016-01777 did not contain a claim construction because, in its Decision on Rehearing, the previous Board panel stated that it “did not expressly construe the ‘determining a press limitation’ or interpret[] the limitation to require the first two conditions recited in the limitation to be maintained for the duration of the first interval.” Apple Inc. v. Immersion Corp., IPR2016- 01777, Paper 9 at 3 (PTAB Apr. 27, 2017) (Decision Denying Petitioner’s Request for Rehearing). Thus, the prior Board decision outcome was not reliant on any particular claim interpretation or characterization of Figure 3; instead, it faulted the petitioner in that case for not considering the three conditions as a whole in the manner required by the claims. Id. at 3–4 (explaining that the petitioner needed to show the “‘first interval has elapsed’ condition as a part of the ‘determining a press limitation’” (emphasis added)). Notwithstanding, and for the sake of clarity, to the extent the prior Board decision in IPR2016-01777 characterized Figure 3 of the ’507 patent to require the pressure and change in pressure conditions to be met during the entire interval, we agree with Valve that such a reading of Figure 3 is incorrect. As Valve points out in its analysis, with which we agree, the flowchart in Figure 3 allows for both the pressure and change in pressure conditions to be met during some but not all of the entire time interval in certain circumstances. Pet. 12–14.3 In summary, we agree with Valve that the three conditions of the “determining a press” limitation are independent insofar as satisfaction of one condition is not predicated on the satisfaction of another condition. In our view, however, that point is merely reciting what the claim already requires—namely, that “determining a press” is defined as the satisfaction of the three conditions. Nothing more is required. Thus, we do not see the need to construe independent claim 1 beyond its plain language.” slip op. at 8

    “Relying on the testimony of Mr. Ward, Valve argues the following: [a] person of ordinary skill in the art . . . on November 26, 2003 would have had a Bachelors’ degree in computer science, electrical engineering, or a related field, plus at least two years of industry or graduate level experience with software engineering, haptics programming, and/or human-computer interaction, including experience with user-interfaces and applications involving touchscreens, touchpads, and related technologies. Pet. 7 (citing Ex. 1003 ¶¶ 47–51). Accordingly, we maintain our preliminary determination regarding the level of ordinary skill in the art. See Dec. on Inst. 8. That is, we adopt Valve’s proposed assessment of the level of ordinary skill in the art because (1) it is consistent with the ’507 patent and the asserted prior art; and (2) it is supported by the testimony of Mr. Ward. We apply this assessment of the level of ordinary skill in the art in our obviousness evaluations below.” slip op. at 12

    “Turning to rationale to combine, Valve contends that, because Shahoian recognizes that “[o]ne problem with existing touchpads is that there is no haptic feedback provided to the user” to “assist and inform the user” when interpreting gestures, a person of ordinary skill in the art would have recognized that Astala’s input touch screen 70 was ready for the improvement that Shahoian provides—namely, “haptic feedback associated with touchpad/touchscreen input gestures.” Pet. 17–18 (quoting Ex. 1006 ¶ 6) (citing Ex. 1003 ¶¶ 158–160). Valve argues that a person of ordinary skill in the art would have recognized that incorporating Shahoian’s haptic feedback into Astala’s input touch screen 70 would have introduced certain benefits taught by Shahoian, including, but not limited to, using haptic feedback to inform users of touchpad gestures by “assist[ing] users in noisy environments . . . where sound may not be easily heard by the user.” Id. at 18 (quoting Ex. 1006 ¶ 178) (citing Ex. 1006 ¶¶ 6, 187, 188, 193; Ex. 1003 ¶ 161). Valve also argues that a person of ordinary skill in the art would have been motivated to use Shahoian’s pressure-sensing components in Astala’s input touch screen 70 because, among other reasons, using actual pressure sensors in a touchpad would have provided more accurate determinations of user input. Id. at 19 (citing Ex. 1006 ¶ 41; Ex. 1003 ¶¶ 164–166). Valve asserts there was a reasonable expectation of success in making the proposed combination because it involves “us[ing] Shahoian’s haptic feedback and pressure sensors for their intended use.” Pet. 19–20 (citing Ex. 1003 ¶¶ 180, 181). In addition, Valve asserts that a person of ordinary skill in the art would have reasonably expected Shahoian’s haptic feedback and pressure sensors to succeed in Astala because “Shahoian demonstrates that algorithms for haptic feedback were known and predictable.” Id. at 20 (citing Ex. 1003 ¶ 182). In summary, upon reviewing Valve’s unrebutted arguments and evidence explaining how the combined teachings of Astala and Shahoian account for all the limitations of independent claims 1, 9, and 14, we agree with and adopt Valve’s analysis. See Pet. 17–31, 38–41. Accordingly, Valve has demonstrated by a preponderance of the evidence that the subject matter of these independent claims would have been obvious over the combined teachings of Astala and Shahoian.” slip op. at 19

    “Patent Owner contends that a POSITA would have had a bachelor’s degree in electrical engineering or computer science (or an equivalent degree), and two years of practical or industry experience in the field of human computer interaction (HCI), including implementation of computer-based systems and software for providing haptic feedback effects to a user. . . . Also, a person could have qualified as a [POSITA] with more formal education and less practical or industry experience, or vice versa. PO Resp. 17–18 (citing Ex. 2008 ¶ 17). Although these level of skill definitions are not the same, the differences are minor, and Patent Owner does not argue that its level of skill definition is dispositive. To the contrary, Patent Owner asserts that “[i]n any event, the challenged claims of the ’260 Patent are patentable under either . . . definition.” Id. at 18. We apply Petitioner’s level of skill but would have reached the same result had we applied Patent Owner’s.” slip op. at 6

    “As we explained in our Institution Decision, we disagreed then, and still disagree, “that the second pressure must be detected after the first pressure is detected (or that the third pressure must be detected after the first pressure is detected) simply because the second pressure is greater than the first pressure (and the third pressure is greater than the second pressure).” Dec. 27. As we explained there, “[t]he claimed relative magnitudes of the first, second, and third pressures do not define any temporal relationships regarding the detection of the pressures.” Id. We agree with Petitioner that claim 1 recites quantitative relationships for the pressures, not temporal relationships. Reply 4. For example, claim 1 requires “the second pressure greater than the first pressure” but says nothing about when the second pressure must be greater than the first pressure. A key misconception undergirding Patent Owner’s argument is its statement that “a ‘first pressure’ must first exist before the invention can detect that the ‘second pressure’ is greater.” PO Resp. 27 (emphasis added). The claim does not require detecting that the second pressure is greater than the first pressure. Limitation [1c] simply says, “detect a second pressure on the first input device, the second pressure greater than the first pressure.” In other words, all the detection that this limitation requires is detecting a second pressure. The claim then observes that the second pressure is greater than the first pressure but does not require detecting this. Limitation [1e] similarly detects pressure but not the comparison: “detect a third pressure on the first input device, the third pressure greater than the second pressure.” Thus, it does not follow that “a ‘first pressure’ must first exist before the invention can detect that the ‘second pressure’ is greater.” See id. Accordingly, we determine that Patent Owner’s analysis of the claim language is unpersuasive.” slip op. at 10

    “that Komata discloses all the limitations of claim 1. Patent Owner does not dispute that Komata discloses all the limitations of claim 1. Instead, Patent Owner disputes that Komata discloses the order of all the steps of claim 1, based on its construction requiring the steps to be performed in order. PO Resp. 50–54; Reply 17 (observing that Patent Owner “does not dispute that Ground 1 demonstrates how Komata anticipates or renders obvious claims 1–7 if [Patent Owner’s] ordered-steps argument is rejected”); Sur-reply 12–14 (not disputing the Reply’s observation). As Patent Owner’s argument relies on a claim construction we have not adopted, Patent Owner fails to undermine Petitioner’s persuasive showing.7 To the extent, as we note above, that the claims may require a partial ordering (i.e., limitation [1a] preceding limitation [1b] and limitation [1c] preceding limitation [1d], see supra Section I.A.1.a), Petitioner has persuasively shown that Komata discloses such ordering. a. Summary as to Claim 1 For the above reasons, Petitioner has shown by a preponderance of the evidence that claim 1 is anticipated by and would have been obvious over Komata. 3. Dependent Claims 2–7 Petitioner also contends that claims 2–7 would have been obvious over Komata. Pet. 28–35. Patent Owner does not dispute these dependent claims.
