    “We are persuaded and find for the reasons given that Petitioner fails to prove by a preponderance of the evidence that White teaches or suggests “receiving a bus workload for a communication bus and a first processing element workload for a first processing element based on an integrated circuit reaching a limit.” Patent Owner’s expert Dr. Brogioli testifies that “[t]he workload is a function of the demands imposed by, e.g., applications running on the system, and may or may not be subject to direct control, whereas the conditions under which that workload is processed are controlled directly.” Brogioli Decl. ¶ 66. We agree with Dr. Brogioli and find that White’s frequency and voltage monitoring and adjustments do not result in the power management logic receiving the bus workload as recited in claim element 4[a]. Id. ¶¶ 64–66. We find the testimony of Mr. Wyatt on this issue unconvincing. Wyatt Decl. ¶ 103. In support of his opinion that “monitoring the operating voltages and frequencies of the logic core 120A and common logic bridge 110 is monitoring the workload of those components,” he states: “It was well understood that operating frequency and voltage of a component reflect the activity and use, or workload, of that component.” Id. However, he does not provide any evidentiary support for this statement. We, therefore, give it little weight. See PTAB Consolidated Trial Practice Guide 40 (Nov. 2019)5 (“Opinions expressed without disclosing the underlying facts or data may be given little or no weight.”) (citing Rohm & Haas Co. v.

    “Post-institution, Patent Owner proposes a construction for the term “workload.” PO Resp. 15–16. Patent Owner contends that “[a] person of ordinary skill in the art would understand that in the ’494 patent, the term ‘workload’ means ‘an amount of activity over a quantum or period of time.’” Id. at 15. Dr. Brogioli’s testimony supports this construction, as does Mr. Wyatt’s. Brogioli Decl. ¶¶ 36–38; Wyatt Dep. 34:14–36:9. The ’494 patent also supports this construction. Ex. 1001, 8:20–22, 9:60–63.

    “Nowhere does Petitioner or its expert point to an explicit disclosure in Bose of making a comparison of the claimed “bus workload and a bus workload threshold.” Instead, Petitioner relies on its expert’s opinion as to what a person of ordinary skill might have known, without any additional supporting evidence. See, e.g., Pet. 26 (“[A person of ordinary skill] would have understood global PMCU compares a workload threshold as exemplified by the predicted power and performance of each power mode and the monitored workload to select and adjust the power mode of a component” (citing Wyatt Decl. ¶¶ 54–55)). This opinion is not supported by the record. The only disclosure of a comparison in Bose that we have been shown is the comparison of PowerTotal to PowerMax in step 303 of Figure 3, which Petitioner does not rely on to meet the “comparison” limitation in the claim. Hearing Tr. 17:16–20. Also without proper support is Petitioner’s assertion that “a [person of ordinary skill] would have understood that in Bose, selecting or adjusting power mode for a component entails comparing a workload threshold, such as predicted power and performance associated with each power mode with real time statistics, such as the monitored workload of a component.” Pet. 26 (citing Wyatt Decl. ¶¶ 55–56). We determine that for the reasons given, Petitioner fails to demonstrate by a preponderance of the evidence that the claimed comparison element 1[g] of claim 1 is taught or suggested by Bose. We find, therefore, that Petitioner has not demonstrated that claim 1 is anticipated by Bose, nor has Petitioner demonstrated that to a person of ordinary skill, claim 1 would have been obvious in light of Bose.” slip op. at 25

    “Figure 6 of Rauhala has been annotated by Patent Owner to show that the parallel connection (outlined in red) including resistors R1, R2. R3 and switches ka, kb is outside the signal path (highlighted in yellow) through differential amplifier 61. Prelim. Resp. 38. Petitioner identifies R1, R2, R3 and switches ka and kb as the claimed variable impedance. See, e.g., Pet. 39–41. The Petition (and the supporting Baker Declaration) do not explain adequately how, under this interpretation by Petitioner and its expert, Rauhala meets the adjusting an impedance “in the signal path” limitation. See Prelim. Resp. 39–41. For the reasons given, therefore, even if we were to disagree with Patent Owner’s construction of “impedance,” we agree with Patent Owner that Petitioner fails to demonstrate sufficiently that Rauhala meets the limitation in claims 7 and 19 requiring “dynamically adjusting one or more of an impedance . . . in the [receiver] signal path.” For the reasons given, we determine that Petitioner has demonstrated a reasonable likelihood of prevailing on its challenge to claims 11 and 13 as anticipated by Rauhala.

    “We disagree. Noting in the language of the claims requires that these method steps be performed by separate components, or that these method steps “provide two different channel indications at once” (Prelim. Resp. 38), only that they be performed as stated in the claim. In that respect, this case is distinguished from In re Robertson, where the Federal Circuit determined that the “third fastening means” required by the claims was not inherently disclosed by the prior art. Robertson, 169 F.3d at 745 (“The [prior art] patent does not expressly include a third fastening means for disposal of the diaper, as claim 76 requires.”). In further contrast to this case, Robertson addressed mechanical elements of a product (fasteners for disposable diaper), not steps in a process. More pertinent to our facts is the Federal Circuit’s decision in Microsoft Corporation v. Uniloc, 2017 LLC, No. 2021- 2039, 2022 WL 11531235 (Fed. Cir.

Cir. 1996) (corroboration requirement “arose out of a concern that inventors testifying in patent infringement cases would be tempted to remember facts favorable to their case by the lure of protecting their patent or defeating another’s patent”). Similarly, an inventor’s testimony alone is insufficient to establish an earlier reduction to practice. Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1169–71 (Fed. Cir. 2006). Instead, a party seeking to prove an actual reduction to practice must proffer evidence corroborating that testimony. Id. at 1170. The sufficiency of corroboration is determined according to a “rule of reason.” Price v. Symsek, 988 F.2d 1187, 1195 (Fed. Cir. 1993). This, however, does not dispense with the requirement that some independent evidence provide corroboration. Coleman, 754 F.2d at 360. The requirement of “independent” corroboration requires evidence other than the inventor’s testimony. In re NTP, Inc., 654 F.3d 1279, 1291–92 (Fed. Cir. 2011). 3. Discussion We find that Patent Owner has not met its burden of establishing that Mr. Kuster conceived and reduced to practice his invention prior to the filing dates of Hsiao or He. By itself, Mr. Kuster’s testimony is insufficient to establish that he reduced his invention to practice prior to the November 23, 2010, filing date or Hsiao or the June 2, 2010, filing date of He. “Throughout the history of the determination of patent rights, oral testimony by an alleged inventor asserting priority over a patentee’s rights is regarded with skepticism, and as a result, such inventor testimony must be supported by some type of corroborating evidence.” Woodland Tr. v.

    “We do not agree with this argument. “The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference; nor is it that the claimed invention must be expressly suggested in any one or all of the references. Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” MCM Portfolio LLC v. Hewlett-Packard Co., 812 F.3d 1284, 1294 (Fed.

Moreover, “[a] person of ordinary skill is also a person of ordinary creativity, not an automaton,” so the fact that it would take some creativity to carry out the combination does not defeat a finding of obviousness. KSR, 550 U.S. at 421; see also ClassCo, Inc. v. Apple, Inc., 838 F.3d 1214, 1219 (Fed.

We find there is support for making this combination of He and Cheng in the testimony of Dr. Baker that addition of a controller is “conventional” in USB flash drives. Baker Decl. ¶ 167. We find that for the reasons given by Dr. Baker, a person of ordinary skill would have added a controller to He. We determine that the combination of He and Cheng teaches each limitation of claim 11.

    “attorney argument, not evidence.” Pet. Reply 26. We agree. Patent Owner does not back up its argument with testimony or other credible evidence. To demonstrate long-felt need, a patentee must point to an “articulated identified problem and evidence of efforts to solve that problem” which were, before the invention, unsuccessful. Tex. Instruments v. Int’l Trade Comm’n, 988 F.2d 1165, 1178 (Fed. Cir. 1993). All Patent Owner proves, if anything, is that after the USB 3.0 specification issued, a number of companies rushed in to provide contacts that met the new standard. Patent Owner does not demonstrate that they failed where Mr. Kuster succeeded. In fact, there is no evidence that Mr. Kuster ever commercialized his invention.8 8 Victorinox never paid for the work Mr. Kuster did on the USB 3.0 memory device, and to Mr. Kuster’s knowledge, never marketed the product. Kuster Dep. 22:21–24:13. Patent Owner contends “Mr. Kuster’s invention filled the existing need for a durable yet slim USB flash drive compatible with USB 3.0 that was easy to manufacture.” PO Resp. 77. But instead of presenting independent evidence of failure of the others to solve known technical or manufacturing problems, Patent Owner relies on generalized statements concerning the need for USB 3.0 connectors and solutions by others that Patent Owner contends have not been successful.

    “and agree with Patent Owner that the terms “re-routing the course” and “re-route the course” mean “to change at least a portion of the route of the course relative to a previous routing.” That is, there must be a first routing of a course and that routing must be changed by performance of the marine route calculation algorithm to avoid preselected conditions by identifying one or more non-user selected waypoints. The construction is consistent with the words of the claims. The claims do not merely require routing a course, but “re-routing the course.” The ordinary meaning of the prefix “re” is that something is being done again. See Tr. 18 (Petitioner agreeing that “if you put R-E in front of a word, normally that means it’s occurring a second time”). Although the claims do not explicitly recite both an original “routing” of a course that is changed by “re-routing the course,” the original “routing” is implicitly required by the use of the prefix “re.” See Tr. 34 (Patent Owner agreeing that although the claims do not explicitly require an initial routing, the initial routing is implicit in the use of “re-routing”), 44–45 (Petitioner agreeing that “re-routing” ordinarily implies an initial routing).” slip op. at 10

    “Patent Owner’s witness, Dr. Kelley, testified “Stone is silent on its implementation, so it doesn’t actually tell you any of this is being done with current or any circuit structure.” Ex. 1030, Kelley Tr. 68:3–6. We agree. We determine that Stone studies the effect of modulating sequences on the resultant spectral power density of the square edged PWM waveform. Ex. 1020, 2, Figs 1–2. Stone’s disclosure of storing the modulation sequence for the frequency hopping spread spectrum in EPROM is not limited to any particular circuit implementation. Petitioner cites Dobkin as disclosing the relevant implementation— i.e., an implementation that reduces switching noise in a switched power regulator by generating a time varying secondary current to charge a capacitor that causes the output of VCO to vary the switching frequency of the regulator. Ex. 1004, 2:53–3:4. Dobkin varies the switching frequency by a constant amount, e.g., by 50 kHz between 75 kHz and 125 kHz, thereby spreading the noise over a broader spectrum. Id. Stone examines the effect of various switching frequency modulations. Referring to Patent Owner’s TNY256 device, Dr. Kelley testified, “you jitter somewhere around that baseline, but not very far” and “I think the prior reference Stone suggests varying the frequency very, very widely. And then if you read further on, it sort of confirms what I said about the practical difficulties in doing such an implementation.” Id. at 66:16–18, 67:21–68:3. Petitioner’s witness, Dr. Holberg, agrees with Patent Owner’s witness, Dr. Kelley, that Stone identifies potential problems of using large amounts of jitter and asserts that Stone provides a reason for a person of ordinary skill to select the low jitter embodiment of Stone. Ex. 1029, Holberg Suppl. Decl. ¶ 20 (citing (Ex. 1020, 4). Dr. Holberg further testified that a person of ordinary skill would have been motivated to adapt the magnitude of Dobkin’s primary and secondary current sources to implement Stone’s example of a small range of jitter. Ex. 1029, Suppl. Holberg Decl. ¶ 21. In view of the testimony of both Dr. Kelley and Dr. Holberg, we find that Petitioner has demonstrated that a person of ordinary skill would have been motivated to apply the teachings of Stone to jitter by a small amount the switching frequency in a power converter as configured by Dobkin, where the switching frequency is varied by changing a secondary current supplied to a circuit that drives a VCO by an amount less than the primary current.” slip op. at 12

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

    “Petitioner responds that prior litigation concerned only claim 1 of the ’876 Patent, and Patent Owner has failed to show a nexus between the secondary considerations and the merits of the subject matter recited in claim 14. Pet. Reply 16–17. Petitioner argues that “any presumption of a nexus in the IPR is overcome by the fact that PO previously attributed the same evidence of secondary considerations to features of Claim 1 that are not present in Claims 14 or 17.” Id. at 16. Specifically, Petitioner contends that the “digital jitter” feature recited in claim 1 is not recited in claims 14 and 17. Id. at 17. Petitioner notes that Patent Owner’s Vice President of marketing, David Mathews, and Patent Owner’s expert, Dr. Kelley, both agreed that the counter and the digital to analog converter in claim 1 that are not recited in claim 14 make claim 1 digital. Id. at 17–18 (citing Ex. 1031, Transcript of Deposition of David Matthews (“Matthews Tr.”) 11:7–12:9; Ex. 1030, Transcript of Deposition of Dr. Arthur Kelley (“Kelley Tr.”) 59:20–60:16, 62:15–23). Petitioner further notes that, although Mr. Matthews stated he had no knowledge of patent matters and could not speak to the patent claims (Hrg.. Tr. 43:21–45:24), Dr. Kelley acknowledged that claims 1 and 14 are distinguished from each other because claim 1 recites a counter and a digital to analog converter that are not recited features of claim 14 (Pet. Reply 18). Thus, the very features Patent Owner relies upon to demonstrate non-obviousness of the invention recited in claim 1 are not features of the claims that are the subject of the challenges in this proceeding. In view of the above, we agree that the evidence is insufficient to show a nexus between the claimed subject matter and purported secondary or objective considerations as to claims 14–16. In consideration of the above, we are persuaded that there is insufficient persuasive evidence of objective considerations of non-obviousness for claim 14 and dependent claims 15 and 16. Having determined that Petitioner has demonstrated all the limitations of claims 14– 16 are taught in the prior art and that a person of ordinary skill would have been motivated to combine the references as discussed above, we conclude that Petitioner has shown by a preponderance of the evidence that claims 14 and 16 are unpatentable as obvious over Dobkin and Stone and that claim 15 is unpatentable as obvious over the combination of Dobkin, Stone and Manlove.” slip op. at 15

    “The dispositive question is “whether one skilled in the art would reasonably understand or infer” that a reference teaches or discloses all of the elements of the claimed invention. In re Baxter Travenol Labs., 952 F.2d 388, 390 (Fed. Cir. 1991). A reference can anticipate a claim even if it “d[oes] not expressly spell out” all the limitations arranged or combined as in the claim, if a person of skill in the art, reading the reference, would “at once envisage” the claimed arrangement or combination. In re Petering, 301 F.2d 676, 681 (CCPA 1962), Kennametal, Inc. v. Ingersoll Cutting Tool Co., 780 F.3d 1376, 1381 (Fed. Cir. 2015); see also In re Preda, 401 F.2d 825, 826 (CCPA 1968) (noting that “in considering the disclosure of a reference, it is proper to take into account not only specific teachings of the reference but also the inferences which one skilled in the art would reasonably be expected to draw therefrom”). We are persuaded by Petitioner’s arguments concerning Habetler. A conventional implementation of a triangle wave generator uses known VCO circuitry that responds to a voltage control signal—Petitioner notes that Danstrom, discussed in the Petition, discloses such an oscillator where internal charging current, and thereby the slope of the triangle wave, is controlled by an input voltage. Pet. Reply 5–6 (citing Ex. 1011, 3:38–55, fig. 2). Patent Owner points out that voltage summing circuits are well-known. PO Resp. 16–17. But the notation in Habetler is not a standard circuit diagram with a junction or node, where the sum of the incoming and outgoing currents are equal. Instead, Habetler’s description of the implementation in Figure 4 explicitly discloses summing voltages using the same notation in Figure 4 that Habetler uses in Figure 5. In view of Habetler’s explicit disclosure and use of identical notation in Figures 4 and 5, we agree that in Figure 5 Habetler illustrates a summing block, and that a person of ordinary skill could reasonably infer the use of a well-known voltage summing amplifier to implement this function to supply a control voltage to Habetler’s triangle wave generator. Thus, we are persuaded that Petitioner has shown Habetler discloses all the limitations of method claim 17. Claim 18 recites the further limitation of clocking a counter with the output of the oscillator. Figure 5 of Habetler, as shown in Petitioner’s annotations, includes a triangle generator and a peak detector used to clock a counter. Thus, we are persuaded that Petitioner has demonstrated that Habetler discloses the further limitation recited in claim 18. For these reasons, we find that Petitioner has shown by a preponderance of the evidence that claims 17 and 18 are unpatentable as anticipated by Habetler.” slip op. at 20

    “Patent Owner responds that the “Petition should be denied because it fails to provide the required evidence necessary to establish the prior art status of [the MR810] technical manual.” Prelim. Resp. 25. Patent Owner asserts “[w]hether a reference has been established as prior art is not merely an evidentiary matter, but a substantive element of Petitioner’s prima facie case of invalidity.” Id. Patent Owner responds to the proofs that its own manual was published by April 2004, including the issue date appearing in the Manual itself, by challenging them as “unclear”: In attempting to establish the prior art status of the MR810 Manual, i.e., that it was “published in April 2004,” the Petition purports to rely on an “April 2004” “Date Issued” date corresponding to Revision C on page 6 of the MR810 Manual. Pet. at 6; Ex. 1006 at 6. But it is unclear from the document what this means, or to whom the document was actually “issued.” Id. at 27–28. We do not find this argument, coming from the party that produced the Manual and presumably knows when it was published, to be credible. Instead, on this record, we determine that Petitioner’s showing that the MR810 Manual was published in April 2004 is sufficient at this stage. Nor do we agree with Patent Owner’s suggestion that the determination whether the Manual qualifies as prior art is not “evidentiary.” See Fed. R.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownNo construction neededMixed

    “We are persuaded by Petitioner’s argument that their construction is correct as to some, but not all challenged claims. Specifically, claim 1 identifies the “heater wire” and “identification elements” as separate elements. “Where a claim lists elements separately, the clear implication of the claim language is that those elements are distinct components of the patented invention.” Becton, Dickinson and Co. v. Tyco Healthcare Group, LP, 616 F.3d 1249, 1253 (Fed. Cir. 2010) (internal quotation marks and alterations omitted). Furthermore, we agree with Patent Owner that the ’345 patent specification “consistently teaches that the heater wire is a separate component connected in series with the identification element.” Prelim. Resp. 34–37. As the Federal Circuit said in Microsoft Corp. v. Proxyconn, Inc., 789 F.3d 1292, 1298 (Fed. Cir. 2015), “[t]he protocol of giving claims their broadest reasonable interpretation . . . does not include giving claims a legally incorrect interpretation.” (internal quotation marks omitted). Further, the Court stated: “Even under the broadest reasonable interpretation, the Board’s construction cannot be divorced from the specification and the record evidence.” Id. (internal quotation marks omitted). We conclude, therefore, that the terms “heater wire” and “identification element” in challenged claim 1 and its dependent claims 2 and 4–7 should be construed as requiring separate elements. Claims 10 and 11 present a different situation. These claims depend from claim 8. That claim, directed to a method for identifying a conduit attached to an apparatus, recites the following step: “attaching a conduit comprising a heater wire including an identification element to said apparatus.” (emphasis added). In the context of these claims, and based on the language of the claims themselves, we conclude that “a heater wire including an identification element” could reasonably be construed to encompass a heater wire that is also the identification element.” slip op. at 10

    “the ’176 grandparent application is insufficient. “Entitlement to a filing date does not extend to subject matter which is not disclosed, but would be obvious over what is expressly disclosed.” Lockwood v. Am. Airlines Inc., 107 F.3d 1565, 1571–72 (Fed. Cir. 1997); see also Reply 5–6. We find that the cited disclosures in the ’176 grandparent application do not describe the density, size, depth, or height of the deformities at approximate midpoints between adjacent pairs of light sources. As discussed above, Patent Owner maintains that a skilled artisan reading the ’176 grandparent application would know that “the approximate midpoint between the two light sources is an area farther away from a light source.” PO Resp. 28 (emphasis added). We are not persuaded by this argument, for it does not establish that the approximate midpoint between adjacent pairs of light sources is the only area farther away from a light source. As Petitioner points out, “the increased distance from the light source is not limited to a distance along the length of the panel member, along the width of the panel member, or along any direction at all.” Reply 11.

Petitioner contends that [w]ith this motivation in mind a [person of ordinary skill in the art] would have recognized that adding the multi-carrier 802.11a modulation scheme to the modulation schemes already available in the Wu system would have been a simple addition, if a technique was available for using a channel estimate obtained from data modulated according to a single carrier modulation scheme for acquisition of data modulated according to a multi-carrier modulation scheme[,] and supports that contention with testimony by Dr. Almeroth. Id. at 48 (citing Ex. 1120 ¶¶ 43–47, 65–68). Petitioner identifies such a technique as disclosed by Böhnke. Id. at 49. Böhnke “relates to the mapping of data and pilot symbols in an OFDM-system.” Ex. 1113, col. 1, ll. 4–5. Figure 2 of Böhnke is reproduced below. Figure 2 illustrates a sequence that includes a first OFDM modulated signal S1, a midamble MA that can be OFDM modulated or single-carrier modulated, and a second OFDM symbol S2. Id. at col. 4, ll. 36–41. The midamble can be used for the transmission of pilot symbols, which “are necessary for a channel estimation such as to effect coherent detection of e.g. OFDM-modulated signals,” and such pilot symbols can be created by a single carrier modulation with a known training sequence. Id. col. 1, ll. 7–9, col. 5, ll. 45–49, col. 5, ll. 61–63. Böhnke, thus, uses the channel estimation obtained from the single-carrier training sequence to detect multi-carrier OFDM symbols by matching bandwidth and performing synchronization. Id. at col. 2, ll. 43–45, col. 2, ll. 61–62. Petitioner reasons that the Böhnke channel-estimation techniques “provide a way to combine a high-rate, multicarrier OFDM data transmission scheme with a single carrier training sequence” and that [w]ith this background, a [person of ordinary skill in the art] investigating options for including the multi-carrier 802.11a standard in the Wu system would have appreciated that Bohnke’s channel estimation techniques could be applied to Wu’s single-carrier 802.11b preamble and used for acquisition of data modulated according to multi-carrier 802.11a.” slip op. at 12
