Claims 1, 3, 5, 10, 13, 16, 17, 25–29, and 33–35 were not shown unpatentable under §103 over Oe and Etsuo because the proposed combinations lacked sufficient reasoned support.

“persuaded Petitioner has provided sufficient articulated reasoning with rational underpinning explaining why one with ordinary skill in the art would have modified the teachings of the applied references to address the noted differences. See KSR, 550 U.S. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (“[R]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.”)). We consider Petitioner’s first reason to combine Oe and Etsuo “because they are in the same field of backlighting for liquid crystal display devices.” Pet. 36. The mere fact that both Oe and Etsuo are in the same field of endeavor falls short of an adequate rationale. The same field of endeavor analysis is merely the jumping-off point in reaching the determination of whether a claimed invention is obvious. See K-TEC, Inc. v. Vita-Mix Corp., 696 F.3d 1364, 1375 (Fed. Cir. 2012) (to qualify as prior art in an obviousness analysis, references must be analogous art—either from the same field of endeavor, or reasonably pertinent to the problem with which the inventor is involved). Next, we consider Petitioner’s second reason to combine because “both Oe and Etsuo relate to backlight devices that use light sources located at edges of a light guide.” Pet. 36 (citing Ex. 1004 ¶ 165). Although Petitioner relies on the testimony of Dr. Escuti, he does not proffer any persuasive facts, data, or analysis to support his opinion. See Ex. 1004 ¶ 165 (“Also, both Oe and Etsuo relate to backlight devices that use light sources located at edges of a light guide.”). Merely repeating an argument from the Petition in the declaration of a proposed expert does not give that argument probative value. Dr. Escuti’s opinion lacks sufficient support. For this reason, we do not credit the testimony of Dr. Escuti on this issue. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). Petitioner’s second reason is also unavailing because it does not address the entirety of Petitioner’s proposed modification. As discussed above, Petitioner relies on the disclosure in Etsuo for both the position of the plurality of light sources adjacent a single input edge claim element, as well as the output distribution having a greater width component than height component claim element. Petitioner’s reasoning, directed only to the use of light sources at the edge of the light guide, does not explain sufficiently why one of skill in the art would have replaced a single light source positioned adjacent one input edge of Oe, with the plurality of light sources disclosed by Etsuo that have an output distribution defined by a greater width component than height component.” slip op. at 20

“We have reviewed the testimony from both Dr. Escuti, and Patent Owner’s expert, Mr. Werner (Ex. 2021). We find that both experts have, at times, taken liberties in proffering conclusory statements without real analysis.5 However, it is within our discretion to assign the appropriate weight to the testimony of both Dr. Escuti, and Mr. Werner. See, e.g., 5 Under our rules, expert testimony that does not have a proper basis is entitled to little or no weight. 37 C.F.R. § 42.65(a). Yorkey v. Diab, 601 F.3d 1279, 1284 (Fed.

“taken into account. In making this determination, we were aided by expert testimony. According to Dr. Escuti, “a person of ordinary skill in the art relevant to the ’660 Patent would have at least an undergraduate degree in physics, optics, engineering, or applied mathematics AND 3 years of work experience (or a graduate degree) in a field related to optical technology.” Ex. 1004 ¶ 23. Mr. Werner does not take issue with this testimony, and in fact proposes a similar standard: a person of ordinary skill in the art of the ’660 patent would hold an undergraduate degree in physics, material science, electrical engineering, or mathematics and have one or both of the following: (1) three or more years of work experience in a field related to optical technology; or (2) a graduate degree in a field related to optical technology. Ex. 2021 ¶ 76. We find that Mr. Werner’s definition is too limited in that it does not include a person with an undergraduate degree in optics.

“disclosure in the specification of the ’600 patent to support Patent Owner’s proposed claim construction of “height” and “width.” Indeed, our review of the specification of the ’660 patent reveals that these terms are not defined explicitly or implicitly. For example, the specification states that “the deformities may vary in shape and/or size along the length and/or width of the panel members.” Ex. 1001, 5:43–44 (emphasis added). With respect to the planar optical conductor, claims 1 and 33 each recite, in relevant part, that the input edge has “at least one input edge with a greater cross-sectional width than thickness.” Ex. 1001, 9:11–12, 10:65–67 (emphasis added). Both claims 1 and 33 recite that the output distribution generated by the plurality of light sources is “defined by a greater width component than height component.”4 Id. at 9:15–16, 11:5–6 (emphasis added). Claim 33 recites that the plurality of LED light sources each have “a greater width than height.” Id. at 11:1–2 (emphasis added). Because the terms “width” and “height” are commonly understood, we also consult a general purpose dictionary. “Width” is defined as “the horizontal measurement taken at right angles to the length.” See Merriam- Webster.com, http://www.merriam-webster.com/dictionary/width, (last viewed July 10, 2015).

“Because the terms “width” and “height” are commonly understood, we also consult a general purpose dictionary. “Width” is defined as “the horizontal measurement taken at right angles to the length.” See Merriam- Webster.com, http://www.merriam-webster.com/dictionary/width, (last viewed July 10, 2015). The dictionary definition of height is “the distance from the bottom to the top of something standing upright.” See Merriam- 3 In a related district court proceeding, the claim term “output distribution defined by a greater width component than height component” was determined to have its plain meaning. Ex. 2008, 47. See TR. 21:24–22:8. Webster.com, http://www.merriam-webster.com/dictionary/height, (last viewed July 10, 2015). Within the context of the claims, we are not persuaded by Patent Owner’s contentions that the term “width” is used other than according to its ordinary and customary meaning with respect to the shape of the input edge of the optical conductor, the output distribution of the light source, and the shape of the LED light source. Along this vein, we are not persuaded by Patent Owner’s contentions that the term “height” is used other than according to its ordinary and customary meaning with respect to the light output distribution. Based on this usage in the claims, no express construction is necessary.” slip op. at 10

We also consider Petitioner’s argument in the Reply that, in addition to Etsuo, Petitioner also relies on Oe’s explicit disclosure of “a plurality of point-like sources of light.” Reply 16–17. Petitioner directs us to the passage of Oe cited in its claim chart (Pet. 40), describing how the light source could be “a plurality of point-like sources of light arranged along the incident surface” (Ex. 1024, 7:30–31). Id. at 16. But Petitioner’s arguments in this regard do not address specifically its proffered reason to combine Oe and Etsuo. Indeed, Petitioner does not explain the relevance of the point-like sources of light to the claim element in question. See 37 C.F.R. § 42.22(a)(2) (requiring a full statement of the reasons for the relief requested, including a detailed explanation of the significance of the evidence including material facts, and the governing law, rules, and precedent). Patent Owner contends that “Petitioner never argues that ‘point-like sources’ are equivalent to LEDs.” PO Resp. 10. We agree. Petitioner’s argument that “Oe discloses a plurality of light sources 4 adjacent to the input edges” (Pet. 35 (citing Ex. 1024, 6:5–13; Ex. 1004 ¶ 161)) makes no mention of the specific passage in Oe concerning the point-like sources of light.

“We agree with Patent Owner and are persuaded that the W–2 form and pay stub should not be excluded. Petitioner’s argument based on alleged inconsistencies goes to the weight, not the admissibility, of the evidence. As to the hearsay objections, we agree with the reasoning of Snow, supra, that the EIN and other information are not assertions subject to the hearsay rule. To the same effect are United States v. Koch, 625 F.3d 470, 480 (8th Cir. 2010) (computer flash drive with manufacturer’s label “China” not inadmissible hearsay to prove place of manufacture); United States v. Bowling, 32 F.3d 326, 328 (8th Cir. 1994) (manufacturer’s name stamped on firearm not hearsay). We are persuaded that the EIN and other identifying information on the W-2 and pay stub, like the examples in those cases, are circumstantial evidence of Seals’employment and not assertions by Intersil. We agree that the pay stub is not hearsay and should be admitted.14 Although Petitioner challenges this evidence as untrustworthy, we are mindful of the fact that Petitioner had a chance to cross-examine Mr. Seals on its content.” slip op. at 22
