“III. ANALYSIS A. Level of Skill in the Art Petitioner, relying on the testimony of Mr. Williams, contends that a person of ordinary skill in the art “would have had at least a bachelor’s degree in computer science, electrical engineering, or a similar field, and would have had approximately two years industry experience in networking or communication systems.” Pet. 3 (citing Ex. 1002 ¶¶ 55–58). Patent Owner does not dispute Petitioner’s proposal. PO Resp. 9. Petitioner’s proposal is consistent with the technology described in the Specification and the cited prior art. On the complete record, we adopt this level of skill.” slip op. at 9

“We have considered the parties’ citations to the specification and find examples that support Petitioner’s view that the term “entity” is broad enough to encompass dispatchers and individual users. See e.g., Ex. 1001, 3:52–4:5, 7:18–20, Fig. 1). However, we find no disclosure that redefines “entity” or excludes dispatchers and individual users from the category of “entity.” Patent Owner’s best examples (e.g., Ex. 1001, 1:15–21, 3:59–62) are no more than non-limiting examples. On the complete record, we conclude that “entity” is broad enough to include dispatchers and individual users.” slip op. at 20

“Although the parties formulate slightly differently their respective assessments of the skill level, neither party disputes directly the other’s assessment nor makes any arguments related to the assessments. See generally Pet.; PO Resp. The ’221 patent states its disclosure “relates, in general, to integrated circuits and, more particularly, to power converter integrated circuits.” Ex. 1001, 1:9–11. In view of the foregoing, we adopt Patent Owner’s formulation of the level of ordinary skill in the art. Further, this level of ordinary skill is reflected by the prior art of record. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art itself can reflect the appropriate level of ordinary skill in the art).” slip op. at 8

“construction must begin with the words of the claims themselves.”); In re NTP, Inc., 654 F.3d 1279, 1288 (Fed. Cir. 2011) (citing Phillips v. AWH Corp., 415 F.3d 1303, 1312 (Fed. Cir. 2005) (en banc)) (“As with any claim construction analysis, we begin with the claim language.”). None of the challenged claims (nor even unchallenged claim 8) recites the claimed disabling or terminating occurs in response to the detect signal independent of other circuit conditions or in response only to the detect signal. See Ex. 1001, 12:5–14:36. For instance, independent claim 4 merely recites, “wherein the control circuit disables the switched drive control signal in response to the detect signal.” Id. at 12:49–51. Independent claim 7 similarly recites, “wherein the gating circuit disables the drive control signal in response to the detect signal.” Id. at 13:11–13. Independent claim 9 discloses only, “a first comparator . . . having an output for disabling the pulse generator.” Id. at 13:27–30. Finally, independent claim 15 requires, “comparing the error signal to a reference signal . . . to terminate the step of generating in response to the error signal.” Id. at 14:21–23. Therefore, the plain language of the challenged claims does not, standing alone, support adoption of Patent Owner’s proposed construction.” slip op. at 13
- Expert testimonyPetitioner expert creditedDecided for petitioner
“testimony from their respective declarants on whether one of ordinary skill in the art would understand “in response to” as requiring “independent of other circuit conditions.” Compare Reply 2–3 (citing Ex. 1016 ¶¶ 18–21, 26–30; Ex. 2003, 43:16–45:1) with PO Resp. 14–15, 17 (citing Ex. 2001 ¶¶ 42, 44–45.) and Sur-Reply 11–12 (citing Ex. 2001 ¶ 45). Patent Owner further directs our attention to a single sentence of deposition testimony in which Petitioner’s declarant Dr. Szepesi appears to agree with Patent Owner’s construction by stating, in the context of claim 9, that “the output signal of this first comparator disables the output pulses driving the gate of that independent of anything else.” PO Resp. 8 (citing Ex. 2003, 44:16– 45:1). Petitioner rebuts Patent Owner’s arguments by identifying additional deposition testimony and statements made in a second declaration offered by Dr. Szepesi opposing Patent Owner’s construction. Reply 2–3 (citing Ex. 1016 ¶¶ 18–21, 26–30; Ex. 2003, 43:16–45:1). For instance, immediately before the statement Patent Owner cites, Dr. Szepesi testified: Q: “So is it your opinion that an output for disabling the pulse generator must disable the pulse generator regardless of the other conditions in the circuit?” . . . A: “I don't understand your question. I said disabling the pulse generator means that the output of the pulse generator which is providing the pulses to the gate of the main switch, those pulses are disabled. That’s what it means in my opinion in this context.” Ex. 2003, 43:24–44:9. And, in his supplemental declaration, Dr. Szepesi states: As a first matter, I opined during my deposition that “an output disabling a pulse generator” means that “the output signal of this first comparator disables the output pulses driving the gate of that independent of anything else.” But, at the time of my deposition I had not done a focused claim construction analysis of the limitation “a first comparator […] having an output for disabling the pulse generator.” This is because I hadn’t anticipated there being a dispute relevant to the validity analysis in view of what I understood as the plain meaning of the language. Despite the quote that Patent Owner relied upon, I believe now that a POSITA would not understand the claim language to require the first comparator to disable the output pulses independent of anything else. This belief is consistent with my responses to the first two of three successive questions in which I was asked about “disabling the pulse generator.” It is my opinion that the operation of the disclosed embodiment requires the presence of other conditions precedent before the first comparator can disable the drive pulses and this requirement is not excluded by the claim language. Ex. 1016 ¶ 18 (emphasis added). Our reviewing court has made clear that extrinsic evidence “is generally of less significance than the intrinsic record” in matters of claim construction. Wi-LAN, Inc. v. Apple Inc., 811 F.3d 455, 462 (Fed. Cir. 2016) (citation omitted). Here, beyond competing declarant testimony, neither party has entered into the record extrinsic evidence, such as dictionary definitions or contemporaneous usage in the art, addressing the scope of “in response to.” Having considered the testimony upon which Patent Owner relies and weighing it against the claim language itself, the Specification’s disclosures set forth above, and the contrary testimony of Petitioner’s declarant, we find on balance that it does not warrant departing from the plain and ordinary meaning of “in response to” as Patent Owner urges. See In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994) (holding that an inventor may define specific terms used to describe invention, but must do so “with reasonable clarity, deliberateness, and precision”) (quoting Intellicall, Inc. v. Phonometrics, Inc., 952 F.2d 1384, 1387-88 (Fed. Cir. 1992)).” slip op. at 17

“Claim 4 further recites, “a control circuit having an input coupled for receiving the detect signal, wherein the control circuit disables the switched drive control signal in response to the detect signal.” Patent Owner’s sole contention with respect to claim 4 is that “[t]he alleged detect signal in Hwang does not satisfy this limitation” because “unlike the ’221 patent, the alleged ‘control circuit’ does not disable the switched drive control signal ‘in response to the detect signal’ independent of other circuit conditions.” PO Resp. 15–16. As discussed above, we decline to import into claim 4 a requirement that the claimed disabling must occur independent of other circuit conditions. See supra Section III.C.1. Because Patent Owner’s argument relies on a claim construction that we rejected above, we are not persuaded that Hwang fails to meet the limitations of claim 4. Rather, having reviewed the evidence cited by Petitioner, we agree with Petitioner that Hwang discloses the limitations of independent claim 4, arranged as recited in the claim. Petitioner’s analysis, as supported by the Szepesi Declaration, further demonstrates where Petitioner contends each element of dependent claims 5 and 6 is disclosed in Hwang. Pet. 21–24. Patent Owner does not dispute Petitioner’s analysis beyond the argument raised with respect to claim 4. See PO Resp. 17. Having reviewed the evidence cited by Petitioner, we agree with Petitioner that Hwang discloses the limitations of dependent claims 5 and 6, arranged as recited in these claims, and we adopt that analysis as our own. Accordingly, for the foregoing reasons, we find Petitioner has shown by a preponderance of the evidence that Hwang anticipates claims 4–6.” slip op. at 25

“There are two problems with Petitioner’s assertion. First, Petitioner has not shown a reason to combine Kogge with Huey and the ATM UNI Specification. Second, to the extent this reference is used to show the scope and content of the art at the time of the invention, Kogge makes it clear that parallelism and pipelining are different concepts that are “generally discernably different in their general approach.” Ex. 1033, 1. Petitioner has not explained how Kogge shows that putting packets through the pipeline without waiting for the previous packet to finish would be considered operating in parallel given that this reference distinguishes parallel operation from pipeline operation. Petitioner argued at the oral hearing that Patent Owner was advocating “a particular flavor of parallelism, as opposed to what’s understood by normal parallel pipelining.” Tr. 41:6–14. However, neither Petitioner nor its declarant has explained what “normal parallel pipelining” is or what the basis is for us to define “normal parallel pipelining.” Thus, we are not persuaded by Petitioner’s contention that one of ordinary skill in the art would modify Huey to meet the limitation of performing at least two of said steps “in parallel using a pipeline.”” slip op. at 33
