“On this record, we determine that Petitioner advances Dr. Medlin’s testimony to make out a claim limitation that is not suggested, much less taught, by the text of the prior art reference at hand. Because that testimony lacks objective support or adequate technical reasoning, it is entitled “little weight” and, moreover, is insufficient to support institution of trial. Xerox Corp. v.

Although Patent Owner is correct that not every embodiment needs to be reflected in every claim, and indeed, some embodiments may not appear in any claim, we do not agree that there is evidence supporting Patent Owner’s argument that the construction of “communications unit” should be narrowed to the embodiment requiring only one DRU/antenna. The cited claims do not indicate that multiple units may not transmit at the sets of frequencies recited. Additionally, although Patent Owner cites claim 16 as requiring that each communications unit is a single DRU, if that were a correct reading of claim 16, it is not clear what the claim recitation would add, as it would not narrow the prior recitation of a “communications unit” from claim 15.

In contrast, § 311(b) permits challenges “on the basis of prior art consisting of patents or printed publications.” The language in § 311(b) implies that, unlike CBMs, IPRs are not limited to prior art challenges solely under § 102(a).

Based on Dr. Baker’s testimony, Petitioner provides several factors that a person of ordinary skill in the art would have considered when designing Nerone’s circuitry to satisfy the “matching” requirement of limitation 7(f). Pet. 18 (citing Ex. 1002 ¶ 120). Dr. Baker supports his testimony concerning the knowledge of these factors by one of ordinary skill with reference to disclosures in Cross and Martin. Ex. 1002 ¶¶ 121–123. Neither Patent Owner nor Dr. Ducharme dispute that a person of ordinary skill in the art would have known to consider these factors when designing Nerone’s circuit. See PO Resp. 30–43; Ex. 2001 ¶¶ 89–106. Petitioner then explains how a person of ordinary skill in the art would have used these factors to apply the teachings of Martin to configure Nerone’s circuitry so that “the forward voltage of the series-connected LEDs [] approximately match[es] the rectified AC voltage output of the above-described LED driver circuit.” Pet. 21; id. at 20–21; see also Ex. 1107 ¶ 29 (“a person of ordinary skill in the art would have understood and would have been capable of determining the appropriate number of LEDs based on the application and design of Nerone’s system such that the forward voltage drop of the LEDs . . . matches the rectified AC voltage output . . . to mitigate against overdriving or underdriving the LEDs.” (citing Ex. 1074 ¶¶ 30–31, Fig. 2)). For these reasons, we find that it was not necessary for Petitioner to provide a specific numerical calculation of the number of LEDs in its proposed modification of Nerone. We also agree with Petitioner that “matching the input voltage to the forward voltage of the LEDs had become a matter of routine optimization.” Pet. 19. Patent Owner contends that this statement is “vague and conclusory.” Sur-reply 12–13. Petitioner, however, supports this statement with the testimony of Dr. Baker. Ex. 1002 ¶¶ 120–123. Dr. Baker’s testimony, which we credit, is corroborated by both Cross and Martin. See id. (citing Ex. 1015 ¶¶ 2, 21, 22 Fig. 5; Ex. 1074 ¶ 30). In particular, Cross specifically discloses that “[t]he number of LEDs employed will vary with the intended lighting application and the value of the rectified DC voltage, wherein optimization of such is well within the skill of those in the art.” Ex. 1074 ¶ 30. Patent Owner does not dispute Cross’s statement that optimizing the number of LEDs is within the skill of an ordinarily skilled artisan. See PO Resp. 40. Martin chooses the number of LEDs “such that the maximum voltage across each individual LED . . . is low enough so as to not damage the LEDs.” Ex. 1015 ¶ 22. It also specifically discloses that “[t]he voltage across each of the individual LEDs in the array is the line voltage divided by the number of LEDs in series.” Id. (emphasis added). Consequently, Martin uses “voltage matching” to determine the number of LEDs so as not to damage the individual LEDs. See also Ex. 1002 ¶¶ 120–124 (Dr. Baker explaining that a skilled artisan “configuring Nerone’s circuit 400 would have recognized that the forward voltage of the series-connected LEDs should approximately match the rectified AC voltage output of the above-described LED driver circuit.” Id. ¶ 124.). Martin’s disclosure, thus, aligns with the reason for “matching” described in the ’400 patent. Ex. 1001, 2:24–35.” slip op. at 36

We agree with Petitioner, however, that the reflector embodiments depicted in Figures 10A–C are just one potential way of utilizing a reflective layer in Schultz, and one of ordinary skill in the art would have understood that use of an unfolded reflective layer is contemplated, and would be beneficial in, the planar embodiments of Schultz, such as the planar embodiment depicted in Figure 1.

“to use a reflective coating or substrate in Birrell because “the use of a reflective substrate to provide mechanical support for an array of LEDs was well known in the art.” Pet. 14. Petitioner further contends that Schultz expressly discloses that reflective coatings are beneficial as they prevent light from an LED die being “unutilized due to absorption or scattering of the light.” Id. at 14–15 (quoting Ex. 1046 ¶ 48); Ex. 1046 ¶ 49 (Schultz explaining that “reflective surfaced materials” provide a “higher probability” that light reflected from the LEDs will reach the focusing element). Petitioner further contends that one of ordinary skill in the art would have used a reflective substrate in Birrell in view of Birrell’s expressed desire for a uniform optical reflection to provide a uniform light source. Pet. 15 (citing Ex. 1002 ¶ 104; Ex. 1018, 6:6–18; Ex. 1022 ¶ 81; Ex. 1023, 16:16–45). Petitioner contends one of ordinary skill in the art would have had a reasonable expectation of success in using a reflective substrate in Birrell because this would have entailed “the use of known components and mounting techniques to produce the predictable result of an LED circuit that benefited from known properties of reflective base structures, as suggested by Schultz and the knowledge of a [person of ordinary skill in the art].” Id. at 16.” slip op. at 16

“understanding of a person of ordinary skill in the art at the time of the invention. Graham, 383 U.S. at 13, 17. Petitioner asserts that [a] person of ordinary skill in the art (“POSITA”) . . . would have had a bachelor’s degree in electrical engineering, or similar technical field, with two years of relevant experience in the field of design and/or development of LEDs and circuits in the context of lighting control systems. An increase in experience could compensate for less education. Pet. 10–11 (citing Ex. 1002 ¶ 22). Patent Owner does not dispute Petitioner’s definition of the level of ordinary skill. PO Resp. 14.

- Expert testimonyPetitioner expert creditedDecided for petitioner
“Under the correct claim construction, Dowling discloses this limitation because Dowling discloses several examples of two-way switch 190 turning on or off LED circuits, independent of other LED circuits. For example, Dr. Neikirk persuasively testifies that Dowling’s color wash mode (selected by switch 190) discloses this limitation by referring to LEDs that “cycle . . . through the full color spectrum,” turning different colored LEDs on or off. Ex. 1033 ¶ 26 (citing Ex. 1004 ¶¶ 44, 103 (“If two LEDs were used . . . with circuitry to turn each color on or off, four colors could be produced.”) (emphasis added)). As another example, Dr. Neikirk persuasively testifies that switch 190 can be used to select a “static color mode to produce, for example, the color red, then only the red LED will be turned on and the remaining LEDs will be turned off.” Id. ¶ 28 (citing Ex. 1004 ¶ 103). Finally, Dr. Neikirk persuasively testifies that switch 190 can select a strobing mode to cause LEDs to “alternate[] green and red,” which a POSITA would have understood to cause “at least one color LED circuit to be turned on or off independent of other LED circuits.” Id. ¶ 29 (citing Ex. 1004 ¶ 47). Patent Owner does not rebut these assertions of Dr. Neikirk. See Sur- reply 7–10. Accordingly, we determine that Petitioner has established that Dowling discloses this limitation.” slip op. at 26
- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner
“We begin our analysis with the claim language. Claim 1 requires a switch to “independently switch on or off at least one of the first LED circuit or the at least one additional LED circuit.” There is no express requirement in the claim that any switching occur independently “of other switches.” In effect, Patent Owner appears to imply that “independently” modifies only the word “switch.” Yet the plain reading of this phrase is that the word “independently” modifies the entire phrase that follows—“switch on or off at least one of the first LED circuit or the at least one additional LED circuit.” As such, the plain language of the claim encompasses switching one of the LED circuits on or off independently of another LED circuit. In other words, the switch can turn on or off either LED circuit by itself, without affecting the other LED circuit. Patent Owner even appears to have had the same understanding pre-institution, arguing that one of Dowling’s modes “is simultaneously controlling all the LEDs, not independently switching one LED circuit on or off.” Prelim. Resp. 19. The specification does not inform the meaning of this limitation because it does not include the word “independently”—this term only appears in the claims. And Patent Owner points us to no discussion of independent switching in the specification by another name. At most, Patent Owner refers to two separate claims and a few specification references that possibly mention two separate switches. Sur-reply 3–4. But Patent Owner’s references to claims 11 and 15 are unavailing, as even if claims 11 and 15 mention different switches, Patent Owner does not sufficiently explain how this compels the meaning it ascribes to “independently switch.” This is true even though claim 11 itself recites a similar “independently switch” limitation. Further, the specification’s mere mention of different switches is also insufficient to draw any conclusion about whether those switches are independently switched from one another. We therefore find no disavowal, lexicography, or any context that would counsel departing from the plain and ordinary meaning of this limitation. As such, we construe “a switch . . . configured to at least one of independently switch on or off at least one of the first LED circuit or the at least one additional LED circuit” in claims 1, 6, and 11 to encompass a switch that switches an LED circuit on or off independently of another LED circuit.” slip op. at 11
