    • Skill levelSkill level patent owner adoptedDecided for patent owner

      “Based on the record as a whole with emphasis on the technical level the ’345 patent’s disclosure and asserted prior art, we agree with Patent Owner that a degree in physics and/or optics rather than engineering could be sufficient. We disagree, however, that “at least two years work experience” is unclear. “At least two years work experience” refers to two or more years of experience working in the field of design, operation, and functioning of imaging systems. We, thus, determine that that a person of ordinary skill in the art as of the date of the invention would have had at least a bachelor’s degree in engineering, physics, or optics with relevant coursework, and the equivalent of at least two years of work experience in the design, operation, and functioning of imaging systems, amounting to familiarity with concepts related to illumination and detection schemes for optical imaging systems. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown” (quoting Litton Indus.

      “The matter now before us is distinguishable from Xerox. As we explain below, Petitioner establishes unpatentability of the amended claims by extensively citing evidence including the prior art at issue. Petitioner and Dr. Georgakoudi properly map the Patent Owner’s amended claims to the explicit teachings of the asserted art. Sur-Reply 1–2. Thus, the position of Petitioner and Dr. Georgakoudi is not unduly conclusory. Rather, Dr. Georgakoudi’s testimony is generally credible because it is consistent with and tied closely to the teachings of the cited art. Thus, when choosing whether or not to cite Dr. Georgakoudi’s testimony and consider whether or not it is credible with respect to any given issue, we do so while considering the record as a whole.” slip op. at 12

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

      “5. Reason to Combine We first address the combination of Petit and Fawzy . Petitioner argues that it would have been obvious to a person having ordinary skill in the art to combine Petit’s long pass filter with Fawzy’s imaging apparatus. Opp. 8. Petitioner’s argument is supported by a preponderance of the evidence. Both Fawzy and Petit teach devices for capturing and analyzing images of dermatological conditions based on light wavelengths reflecting off a patient’s skin. Id. (citing Ex. 1008 ¶¶ 89, 92; Ex. 1020 ¶ 88). The preponderance of evidence supports that a person of ordinary skill in the art would have understood that emission filters, such as those taught by Petit, are a well-known mechanism to predictably filter out wavelengths of light that are not relevant to the imaging at hand. Id. (citing Ex. 1020 ¶ 87). A person of ordinary would have understood that filtering out undesired wavelengths could avoid undesired interference. Id. at 8–9 (citing Ex. 1008 ¶¶ 44,80). Petit teaches a long-pass filter having a cut-on wavelength of 450±25 nm. Ex. 1020 ¶ 98. Such a filter would be helpful in accomplishing Fawzy’s goal of “control[ling] optical coupling of the digital camera to capture only reflected light originating from the interaction of light from the spectral light source with an object being imaged.” Ex. 1008 ¶ 107. The combination would also be helpful for determining effective treatment as Petit teaches. Ex. 1020 ¶ 87. As such, we determine that a person having ordinary skill in the art would have had reason to combine Petit’s long pass filter with Fawzy’s imaging apparatus and would have had a reasonable expectation of success in making the combination.” slip op. at 18

      “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

      “We agree with Patent Owner that the challenged claims relate to light fixtures, LED packaging, and LED chip layer structure and that the ’770 patent claims reflect “a hybrid of the light bulb art and semiconductor art.” Resp. 16. The prior art of record, for example, Begemann, likewise reflects “a hybrid of the light bulb art and semiconductor art.” Id. (quoting Pet. 28). Petitioner’s expert, Dr. Lebby, agreed that a person having ordinary skill in 28:16. 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. Cir. 2001) (prior art itself may reflect an appropriate level of skill). For the purpose of this Decision, we adopt Patent Owner’s description.

      “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. Thus, the statement supports public availability as of June 29, 2000.” slip op. at 21

      “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.

      “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 antennae used in RFID devices versus developing antennae used in RFID devices for inductive coupling). The Specification of the ’250 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 at use 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. Thus, we are not persuaded that the level of ordinary skill should be narrowly confined to developing antenna for RFID devices that are used for inductive coupling. For the purposes of this Decision, we adopt Petitioner’s definition of the level of ordinary skill in the art as “a Bachelor’s degree in electrical engineering or a similar field, and 1–2 years of experience researching and developing antennas used in RFID applications.” Pet. 7.5” slip op. at 10

      “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.
