“Petitioner contends that there is “no meaningful dispute over [the definition of] a POSITA.” Reply 1. We agree. However, we adopt Patent Owner’s definition of the level of skill because we are persuaded that it is more consistent with the problems and solutions in the ’583 patent. In particular, Patent Owner’s definition requires experience with LED devices, whereas Petitioner’s definition makes LED experience optional (“experience with LED devices and/or related circuit design”). We note that the outcome of this decision would not have changed had we adopted Petitioner’s definition.” slip op. at 7

“Petitioner argues, and we agree, that the Piepgras-Michael-Butler combination discloses that the portable telecommunications device can detect a human touch. Pet. 43. Further, Dr. Baker testifies, and we agree, that a POSITA would have understood that the modified device “would use an LED touch display and thus when touched, the LED(s) of the display would change (e.g., turning on and/or changing interface content).” Ex. 1002 ¶ 141. We credit this testimony by Dr. Baker because it is well-supported by evidence. See, e.g., Exs. 1009 (Hack), 1022 (Gillespie); Pet. 43 (citing same).13 Patent Owner does not offer any contrary evidence that would undermine Dr. Baker’s persuasive testimony that a POSITA would have understood that the modified device would use an LED touch display and that when touched, the LED(s) of the display would change (and thus provide light). See Ex. 2001 ¶¶ 105–16 (attacking the sufficiency of Petitioner’s evidence but not disputing Dr. Baker’s core assertion regarding the understanding of a POSITA). It is somewhat ironic that Patent Owner asserts that Dr. Baker’s testimony is “conclusory and not tied to supporting evidence.” Sur-reply 26 (citing Ex. 1002 ¶ 141). In reality, Petitioner supplies ample supporting evidence (e.g., Hack and Gillespie), but Patent Owner denies that we can consider it. See, e.g., Pet. 43 (citing, e.g., Exs. 1009, 1022); PO Resp. 44. Petitioner’s reliance on evidence to show the understanding of a skilled artisan is appropriate because “the obviousness ‘analysis requires an assessment of the . . . background knowledge possessed by a person having ordinary skill in the art.’” Koninklijke Philips, 948 F.3d at 1337. Petitioner does not rely upon references such as Hack and Gillespie to supply a missing claim limitation.14 Rather, Petitioner relies on Butler’s disclosure of a touch screen for this limitation and points to Hack and Gillespie to show that prior art touch screens often included LED displays and that one of ordinary skill in the art would have understood that a touch screen would have provided 13 As we explain below, we need not rely on Swartz. 14 For this reason, Petitioner need not have included Swartz, Hack, or Gillespie in its ground listing, and Petitioner need not show a motivation to combine Swartz, Hack, or Gillespie with Piepgras, Michael, and Butler. light based upon detection of human touch.

Google, 34 F.4th at 1088. Cheyer’s and Martin’s testimony that Dr. Moran’s role was administrative and non-technical with respect to the core infrastructure of OAA is belied by a separate article describing OAA that includes the facilitator and lists Dr. Moran as the lead author. Ex. 1174, 1–2, 4. Indeed, the OAA article lists Dr. Moran and Mr. Cheyer as authors but excludes Mr. Martin. Id. Although Mr. Cheyer disagrees with the article’s description of the origins of OAA and the facilitator (Ex. 2037, 78:23–79:12 (Mr. Cheyer asserting that he “would not agree in the characterization of Open Agent Architecture grew out of [earlier] works” as described in the article)), Mr. Cheyer admits patent]” (id. at 1088), “which is a continuation-in-part of the application that resulted in the ’115 patent” (id. at 1086). in his deposition that Dr. Moran was extremely technical, and probably made technical contributions to OAA (id. at 34:1–20, 64:16–20, 102:2–4).

When viewed in light of Dr. Moran’s status as a joint inventor on the closely related ’931 patent (Ex. 2002, code (75)) and as a lead author of the substantive paper that discusses OAA’s early development, we find Mr. Martin’s and Mr. Cheyer’s admissions—that Dr. Moran made technical contributions to OAA—undermine their testimony that Dr. Moran’s inclusion as an author on the Martin reference was a matter of administrative respect and not a result of a technical contribution. See PO Remand 11; PO Resp. 50–51. Indeed, we find Cheyer and Martin’s general description of Dr. Moran—as an administrator without technical contributions to the Martin reference—is not supported by the full record, which instead supports Dr. Moran’s contributions to technical work that involves the Martin reference, such as contemporary papers and the ’931 patent. See, e.g., Ex. 1174, 2002.

“We disagree. It is clear from the plain language of claim 1 that the claimed “cleaning composition” is a composition for cleaning that includes four named components and has a specified pH. Ex. 1001, 29:2–9. The ’329 patent specification unambiguously teaches that the cleaning composition is for removing residues from semiconductor substrates. Id. at 1:23–29, 2:10–12, 2:17–33, 15:52–55. Although the ’329 patent describes a cleaning composition that comprises a redox agent, a chelating agent, a metal corrosion inhibitor, an organic solvent, and water, we see no reason to construe the term “cleaning composition” itself to require these components. Claim 1 expressly recites expressly including or precluding a chelating agent or a metal corrosion inhibitor. Ex. 1001, 29:2–9. The Federal Circuit advises that the specification “is not a suitable substitute for, nor can it be used to rewrite, the chosen claim language. ‘Specifications teach. Claims claim.’” SuperGuide, 358 F.3d at 875 (quoting SRI Int’l v. Matsushita Elec. Corp. of Am., 775 F.2d 1107, 1121 n. 14 (Fed. Cir. 1985) (en banc)). The ’329 patent specification does teach a cleaning composition that includes a redox agent, a chelating agent, a metal corrosion inhibitor, an organic solvent, and water, but claim 1 is directed to a cleaning composition that expressly requires only a subset of those components. Patent Owner’s proposed construction would effectively rewrite the claim by adding unclaimed components, which we decline to do under the guise of claim construction. See id. (“Though understanding the claim language may be aided by the explanations contained in the written description, it is important not to import into a claim limitations that are not a part of the claim.”).” slip op. at 9

“that Petitioner establishes that the ’329 patent does not provide sufficient written description support for the challenged claims. Pet. 15–43; Ex. 1007 ¶¶ 56–82. More specifically, we find that the ’329 patent does not reasonably convey to a POSA that the inventor was in possession of cleaning compositions that do not include a chelating agent or a metal corrosion inhibitor. There is no dispute, on this record, that the ’329 patent specification explicitly teaches that a redox agent, a chelating agent, a metal corrosion inhibitor, an organic solvent, and water are mandatory components of the cleaning composition described therein. PO Resp. 15 (Patent Owner agreeing with Petitioner that “[t]he ’329 patent’s disclosure is unambiguously explicit regarding mandatory components of the cleaning compositions described therein.” (citing Pet. 17; Ex. 1007 ¶¶ 56–57) (emphasis omitted, alteration in original)); see Ex. 1001, 3:47–48, 3:62–64, 10:24–26, 10:66–11:2, 12:3–4; Ex. 1007 ¶¶ 56–67. Claim 1, however, does not require that the cleaning composition include a chelating agent or a metal corrosion inhibitor. Ex. 1001, 29:2–9. Therefore, establishing proper written description support for claim 1 requires more than showing that the inventor was in possession of a cleaning composition that includes a redox agent, a chelating agent, a metal corrosion inhibitor, an organic solvent, and water; the ’329 patent must also show that the inventor was in possession of a cleaning composition that includes only a redox agent (hydroxylamine), an organic solvent (an alkylene glycol), water, and an alkanolamine.

Walgreens Corp., 589 F.3d 1233, 1238, 1240 (Fed. Cir. 2009). The ordinary observer test for design patent infringement was first enunciated by the Supreme Court in Gorham Co. v. White, 81 U.S. 511 (1871), as follows: [I]f, in the eye of an ordinary observer, giving such attention as a purchaser usually gives, two designs are substantially the same, if the resemblance is such as to deceive such an observer, inducing him to purchase one supposing it to be the other, the first one patented is infringed by the other. Id. at 528. The ordinary observer test requires the fact finder to consider all of the ornamental features illustrated in the figures that are visible at any time in the “normal use” lifetime of the accused product, i.e., “from the completion of manufacture or assembly until the ultimate destruction, loss, or disappearance of the article.” Int’l Seaway, 589 F.3d at 1241. Further, while the ordinary observer test requires consideration of the overall prior art and claimed designs, [t]he mandated overall comparison is a comparison taking into account significant differences between the two designs, not minor or trivial differences that necessarily exist between any two designs that are not exact copies of one another. Just as “minor differences between a patented design and an accused article’s design cannot, and shall not, prevent a finding of infringement” . . . so too minor differences cannot prevent a finding of anticipation.

“Upon review of the record and the parties’ arguments as a whole, we agree with Petitioner that Saito discloses a driver, as that term is used in claim 1 of the ’551 patent. First, our construction of “driver” is broad, constituting any “program, circuitry, or device used to power other programs, circuits, or devices.” And, consistent with the structure of claim 1 of the ’551 patent, this construction does not require that the identified circuit or device actually generate power, only provide power to another device or circuit. switch that turns on or off a power source. Rather, the circuit of Saito monitors the voltage provided at both node A 107 and node B 715 and, depending on the reported voltages, switches between voltage sources to provide power to the LEDs. In this way, the voltage applied to the LED circuit is maintained within a range of roughly 16 and 30 Volts, and the LEDs are driven for a prolonged period of time by capacitors 106 and 107, which Saito explains “cut[s] down the consumption of electric current” and results in more efficient use of power. Ex. 1008 ¶¶ 98–103. We find persuasive Dr. Baker’s testimony that one of ordinary skill in the art would have considered such a circuit to be a “driver,” as recited in claims 1 and 5 of the ’551 patent.

“Dr. Ducharme’s testimony that “the spacing of the chips in Zhang would not likely be so close as to create overheating issues” (Ex. 2002 ¶ 111) is unsupported by any disclosure of the actual spacing of Zhang’s chips. Consequently, his testimony that there would be no overheating concerns in Zhang due to the spacing of the chips is entitled to little, if any, weight. Dr. Ducharme further testifies that the components of Zhang’s driver “could easily increase the temperature of the LED 19 chips on the circuit board, which can cause LEDs to generate less illumination, burn out and otherwise adversely affect their performance.” Ex. 2002 ¶ 126. Dr. Ducharme further testifies that “[i]t is well-known that excessive operational temperatures can reduce the illumination provided by the LEDs, can decrease the operational lifetime of the LEDs, and if the temperature is sufficiently high, it can cause LED junction failure and a burnt-out LED.” Id.
