“declaration addresses the Patent Owner Response and is relevant to the issues at hand. We start with an important observation: claim 18 (the only independent claim at issue) is an apparatus claim; the claim is directed to a “semiconductor light source.” Ex. 1001, 9:52, EPRC 1:32. One requirement of this apparatus is that it comprise “a semiconductor chip” (id. at 9:66) where “said semiconductor chip is a light emitting diode (LED) chip EPRC, 1:34–36. As we explain when addressing claim construction, infra, we adopt Patent Owner’s proposed construction (Resp. 14) of “said semiconductor chip is a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as referring to “a semiconductor LED chip capable of emitting light greater than about 40 milliwatts.” See Section III.D, infra (emphasis added). Because of these recitations, Petitioner bears the burden of establishing that the prior art teaches or suggests a semiconductor LED chip “capable of emitting light greater than about 40 milliwatts.” As explained herein, we determine that in the Petition, Petitioner met this burden by establishing by a preponderance of the evidence that the Krames reference teaches an LED chip that has this capability. Pet. 53 (quoting Ex. 1008, 10). Notably, claim 18 does not require actual operation of anything at greater than 40 milliwatts because claim 21 is not a method claim. Petitioner never had a burden of establishing a method of running the Krames reference’s LED at this power output within a semiconductor light source.” slip op. at 9

While Petitioner’s proposed description of a person having ordinary skill in the art could, in some instances, be sufficient to qualify a person as having ordinary skill, Patent Owner’s proposal is a more complete and accurate description of the level of skill commensurate with the scope of the challenged ’770 patent claims. Patent Owner’s description appears consistent with the prior art and patent specification before us and is supported by witness testimony. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

“Delaware held, with respect to related U.S. Patent 6,465,961, construed “a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as “at least one LED chip is capable of emitting light greater than about 40 milliwatts.” Resp. 14 (citing Ex. 1024, 15–18). Petitioner responds that the phrase “needs no construction” and that Petitioner’s grounds meet this construction. Reply 1. We note that the language of claim 18 does not precisely match the language the District Court considered, it is substantively the same. The record supports a construction very similar to the construction the District Court adopts, and we reference the District Court’s reasoning. Ex. 1024, 15– 18. We, thus, construe claim 18’s recitation that “said semiconductor chip is a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as referring to “a semiconductor LED chip that is capable of emitting light greater than about 40 milliwatts.” It is unnecessary to construe any other claim terms in this Decision because none of the parties’ disputes turn on the meaning of other terms.

- Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedReference is prior artDecided for petitioner
“The facts above are evidence of the Krames reference’s publication as of June 29, 2000, because the facts tend to make the Krames reference’s publication as of June 29, 2000, more probable than it would be without the evidence. See Fed. R. Evid. 401(a) (defining evidence as relevant “if it has any tendency to make a fact more or less probable than it would be without the evidence”). The evidence is sufficient to support publication. Meanwhile, no evidence of record suggests that Krames was not a printed publication as of June 29, 2000. Thus, a preponderance of the evidence supports Krames’s prior art status. Patent Owner argues that Ms. Watters “never establishes a firm date when Krames was purportedly available to the relevant public.” Resp. 21. Patent Owner bases this argument by taking a tortured reading of Ms. Watters’s statement that “[m]embers of the interested public could locate a copy of [the Proceedings] on or after June 29, 2000, the date it was catalogued.” Id. (quoting Ex. 1020, 3); see also Sur-Reply 12–13. The best understanding of Ms. Watters’s statement, in view of the context of Ms. Watters explaining the library’s cataloguing process, is that a member of the interested public had two options: the person could choose to locate the Proceedings on June 29, 2000, or the person could choose to locate the Proceedings after June 29, 2000.

“In the Reply, Petitioner uses the Krames declaration (Ex. 1028) to argue, for example, that a person of ordinary skill in the art would have used a lower amperage than the 1.5 A dc that Patent Owner’s Response focuses on. Reply 8 (citing Ex. 1028 ¶ 22). This use of the Krames declaration is timely because it responds to an argument Patent Owner makes in the Patent Owner Response. 37 C.F.R. § 42.23(b) (“A reply may only respond to arguments raised in . . . patent owner response.”). As to relevancy and whether the Krames declaration is applicable to the facts of this case, the issues at hand are (1) whether or not a person having ordinary skill would have had reason to use the Krames LED with Begemann with a reasonable expectation of success and (2) whether or not the Krames LED is capable of outputting light at greater than about 40 milliwatts. Again, we emphasize that claim 21 does not recite a method where the LED within the recited semiconductor light source actually outputs greater than about 40 milliwatts. The Krames declaration is relevant to the facts of this case because the declaration has bearing on whether or not a person of ordinary skill in the art would have combined the Krames reference’s LED with Begemann’s lightbulb design. See, e.g., Ex. 1028 ¶ 22. Patent Owner argues that evidence must be relevant to motivation to combine “an LED chip from the Krames article (operating at 1.5 amps to produce 170 milliwatts of output)” but claim 21 has no “operating at 1.5 amps to produce 170 milliwatts of output” requirement. What is relevant is that Krames discloses a single chip that has the capability of outputting more or less light depending on operating conditions. Pet. Opp. 3; see also Ex. 1008, 8 (providing that Figure 12 of the Krames reference is described as illustrating “[l]ight output vs. current characteristic of a blue … 1x1 mm2 AlGaInN LED in a power package, compared to a conventional AlGaInN LED in a 5 mm lamp a package”). Because claim 21 does not require actually running the recited LED at any particular wattage or amperage, it is appropriate for the Krames declaration to rebut Patent Owner’s argument that a person of ordinary skill would not have considered using the Krames LED with Begemann at high amperage by explaining that a person of ordinary skill in the art would have considered using the exact same Krames LED with Begemann at a low amperage instead and that at this lower amperage the Krames LED would generate an amount of heat that would be easily dissipated by Begemann’s lamp while still providing an optical output of “greater than about 40 milliwatts” as recited by claim 21. Ex. 1028 ¶¶ 23–24 (citing Ex. 1008, 8). The fact that the Krames LED is configured to run at the high amperage if desired for a different application does not negate the rationale for combining the Krames LED to run at a lower amperage.” slip op. at 14

“The parties are in general agreement as to the level of education (undergraduate degree in electrical engineering or equivalent) and the number of years of experience working with RFID devices (1–2 years), but differ as to the exact nature of that experience (developing antennas used in RFID devices versus developing antennas used in RFID devices for inductive coupling). The specification of the ’304 patent describes its technical field as relating to a smart card that may comprise an RFID (radio frequency identification) chip with antenna components for operating in contactless modes. Ex. 1001, 1:37–54. The specification discusses both inductive and capacitive coupling. See, e.g., id. at 3:14–39. Patent Owner submitted into the record a text titled RFID Handbook, which details different frequencies and types of coupling that may be used by various RFID systems. See Ex. 2005, 22–23. Although this text differentiates between “inductively or capacitively coupled system[s] and microwave system[s] or backscatter system[s]” (id. at 23 (emphasis omitted)), its description of each of these types of RFID devices indicates that an ordinary artisan would have had experience with RFID devices generally.

“Here, we decline to exercise discretion to deny this Petition based upon multiple Petitions for three reasons. First, as we explain in Section III(H) of this decision, the Petition is strong on the merits, and Patent Owner has, at this stage, offered little argument refuting the merits. Second, Patent Owner’s burden to respond to both petitions is lessened by Patent Owner’s familiarity with much of the prior art at issue. As Patent Owner emphasizes, all or nearly all of the art in the Petitions was previously raised either during prior examination or in other inter partes reviews. Indeed, it seems likely that, if the Cree IPR (or related follow on IPRs) proceeds to a decision on the merits, there may be little left unresolved for the instant Petition. Institution here, however, provides Petitioner an opportunity to challenge the ’961 patent based on Krames in the event that the IPR based on Cree does not reach a decision on the merits. Third, while the two petitions present different invalidity grounds (addressing the same claims) and, as explained above, are not wholly redundant, the two parallel petitions have a great deal of overlap. Prelim. Resp. 26 (arguing that the two petitions are “redundant”). Because portions of the petitions are similar, this also reduces Patent Owner’s burden to respond. Thus, based on the totality of specific circumstances unique to these two petitions, we decline to exercise discretion to deny institution based on parallel petitions.” slip op. at 25

“Conclusion as to claim 21 Based on the evidence in the present record, we determine that Petitioner has shown sufficiently for purposes of this Decision that the combination of Begemann, Bogner, and Sugiura teaches or suggests all elements of claim 21 and that Petitioner sufficiently shows that a person of ordinary skill in the art would have had reason to combine the references’ teachings with rational underpinning and reasonable expectation of success.

Petitioner points out that “the claims are not limited to a [Booster Antenna (BA)] operating at any particular frequency range.” Reply 25.

“The express language of claim 1 requires no solubility threshold, and dependent claim 10 of related U.S. Patent No. 10,288,620 B2 demonstrates that, where a solubility threshold was intended by the inventors of these patents, they knew how to expressly set forth that threshold in the claims.

Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
