“In particular, neither Petitioner nor Dr. Josefowicz adequately explain why a POSITA looking for ways to make Hanafusa’s surface roughness low-profile would look to methods to achieve Dobashi’s RSm values. Dobashi teaches that because RSm “can be adopted as the period of waviness, RSm can also be used as an indicator for judgment of the surface.” Ex. 1005, 2:66–3:1, 6:23–26. Dobashi explains that waviness is “an indicator for determining whether the fine pattern forming performance is good or bad,” and “[t]he surface has small waviness and is smooth when RSm is large, and the surface has large waviness Dobashi also teaches that surface roughness Rzjis is used as a low-profile indicator. Ex. 1005, 2:66–3:1. Dobashi, therefore, teaches that RSm is an indicator of surface waviness, which Dobashi explains is different than surface roughness. Id. at 2:66– 3:3, 6:23–29. Given these teachings in Dobashi, neither Petitioner nor Dr. Josefowicz sufficiently explains how or why a POSITA would have been motivated to implement Dobashi’s RSm values to make Hanafusa’s surface roughness low-profile.

“For example, Dr. Randall does not provide adequate explanation or objective evidence to support his opinion that Khatibi’s use of a laser speckle based dilatometer instead of the claimed thermomechanical analyzer “is unlikely to significantly impact the CTE[6] value” because “variations in equipment and a heating speed of 5° C/min would not significantly alter the results.” Ex. 1003 ¶ 58. In particular, Dr. Randall neither explains what constitutes a “significant” impact on CTE, nor provides objective evidence to support his contention that equipment variations and heating differences would not “significantly alter” the resulting measurements. And although Dr. Randall opines that “the heating rate (5°C per minute) is typical for certain devices” such as a thermomechanical analyzer or dilatometer, and “[t]ypically, these devices use temperature ramp rates between 2°C and 20°C per minutes, so the ‘5° C./min’ recited in [1d] is common and should not drastically affect the measurement results,” Dr. Randall fails to point us to any evidence showing that these temperatures are “typical” or that the claimed heating rate is “common.” Id. ¶ 59 (emphases added).” slip op. at 4

“We disagree with Petitioner’s argument because it fails to address Dr. Schubert’s academic and other experience with GaN transistors. Dr. Schubert is currently a tenured full professor in the Department of Electrical Computer, and Systems Engineering at Rensselaer Polytechnic Institute and was previously a tenured full professor in the Department of Electrical and Computer Engineering at Boston University. Ex. 2001, 129. Additionally, Dr. Schubert was the director of Boston University’s Semiconductor Devices Research Laboratory. Ex. 2001, 129. Dr. Schubert persuasively explains that his general expertise is in the field of electrical engineering and applied physics, including semiconductors, processing, and devices and his specific expertise is in the field of semiconductor materials (such as GaN), semiconductor devices, semiconductor integrated circuits, ohmic contacts, Schottky contacts, HEMTs, and optoelectronic devices such as light-emitting diodes (LEDs). Ex. 2001 ¶ 11, App’x A pp.129–137. His experience includes “the design, growth, fabrication, and testing of semiconductor devices as well as the employment of these devices in a variety of applications” and he is “familiar with both the design of such transistors [HEMTs] and the manufacturing processes used for FETs. Ex. 2001 ¶ 11, App’x A, pp. 129–137. He is an author or co-author of numerous text books and articles, and co-inventor of numerous patents, including those dealing with HEMT transistors and GaN devices. Ex. 2001 ¶ 13, App’x A, pp. 129–137. Petitioner fails to present any persuasive argument or evidence that Dr. Schubert’s extensive education and experience regarding GaN transistors is insufficient or lacking such that his testimony should be given little weight. Finally, we disagree with Petitioner’s additional argument that that its expert’s testimony (Dr. Shealy) should be given more weight than Patent Owner’s expert’s testimony (Dr. Schubert) because “[u]nlike Dr. Schubert, Dr. Shealy is one of the pioneer scientists in the field of GaN transistors.” Reply 34 (stating that Dr. Shealy’s research lab built the first GaN HEMT device on silicon in 1999 and citing Ex. 2002, 87:19–238). Obviousness is determined through the lens of a “person of ordinary skill in the art,” not through the lens of a person with extraordinary skill or a pioneer in the field.

Patent Owner asserts that Petitioner’s proposed modification “mish-mashes aspects of Lundahl and Larsen ([while] avoiding the overall teachings of [challenged] claims.” Id. at 56–57. As discussed above, based on our consideration of the current record, Petitioner has provided sufficient motivation for employing Larsen’s flexible five panel configuration. These panels in Larsen already use LEDs as their light source. So, in our view, Petitioner’s incorporation of the five panels includes the lighting source, i.e., LEDs, for those panels taught by Larsen. Further, we note that Petitioner has persuasively asserted that a skilled artisan would have been motivated to use Larsen’s LEDs as they are more cost-efficient and last longer.

In construing claims, district courts give claims their ordinary and customary meaning, which is “the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention.” Phillips v. AWH Corp., 415 F.3d 1303, 1312–13 (Fed. Cir. 2005) (en banc). With respect to the challenged claims, Petitioner contends that no claim term requires express construction. Pet. 11 (citing Ex. 1034 ¶ 106 (Dr. Tucker’s testimony that “the terms in the Challenged Claims would be understood by a POSA to have their plain and ordinary meaning and do not require a special construction or definition”)). On the presents record, we agree with Petitioner that no term requires express construction. C.” slip op. at 12

“through [1e]. Pet. 28–30. Petitioner further relies on “Racz as modified in view of Fitz and Lee,” with respect to elements [1e] through [1h]. See generally, id. at 30–47. Supported by the testimony of Dr. Tucker, Petitioner contends that one of ordinary skill in the art would have been motivated to combine the teachings of Racz, Fitz, and Lee with a reasonable expectation of success of arriving at the claimed invention. Id. at 1–6, 21–27; Ex. 1034 ¶¶ 132–149. In short, Petitioner contends that “[m]ost of the recited RF needle features—including an elongate cannula, a removable RF probe, a conductive tip, and a monopolar configuration—are conventional features disclosed in . . . Racz,” whereas Fitz discloses that a single-tip device, such as disclosed in Racz, “would produce limited ablation volumes and would have motivated a POSA to solve this problem by adding deployable filaments,” as recited in claim elements [1e] and [1f]. Id. at 4–5, 21–22. In addition to its reliance on the multiple electrode tips disclosed in Fitz, Petitioner contends that Lee would have “motivate[ed] a POSA to implement deployable filaments on the tip of Racz’s device using channels within the cannula,” and “also shows how the filaments can extend outwardly around the needle’s tip to advantageously expand and control the ablation volume.” Id. at 5–6. Accordingly, Petitioner contends, one of ordinary skill in the art “would have found it obvious to modify Racz’s device to include the well-known deployable filaments described in Fitz and Lee,” and would have implemented this combination as “a matter of routine engineering.” Id. at 6, 27.” slip op. at 20

“Petitioner argues that, in view of these teachings in Racz and Lee, a skilled artisan would have found implementing Lee’s perimeter filaments (22/1622) on Racz’s distal tip (14/38) to be a routine engineering task. Pet. 39 (citing Ex. 1033 ¶ 179). According to Petitioner, a person of ordinary skill in the arts would have recognized that it would be appropriate to implement Lee’s perimeter filaments (22/1622) without including Lee’s central filament. Id. Petitioner asserts that Lee discloses that any number and arrangement of filaments may be implemented to provide a desired ablation volume. Id. at 38 (citing Ex. 1010 ¶¶ 103, 105, 106). Additionally, Petitioner argues, because Racz’s tip (14/38) is already active, a skilled artisan would have recognized that Lee’s central filament would not be necessary. Id. (citing Ex. 1009, col. 3, ll. 60–63, col. 4, ll. 18–23; Ex. 1033 ¶ 179). Petitioner therefore argues that a person of ordinary skill in the art a person of ordinary skill in the art would have been motivated to implement Lee’s perimeter deployable filaments (22/1622) on the distal tip (14/38) of Racz’s cannula (10/33) for the purpose of expanding and controlling the energy coverage area of Racz’s device. Pet. 40. Specifically, Petitioner asserts that a skilled artisan would have been motivated to implement Lee’s perimeter filaments (22/1622) around Racz’s tip (14/38) to provide a desired ablation volume (e.g., in a full or partial “cone” shape) and omit Lee’s central filament. Pet. 38 (citing Ex. 1033 ¶¶ 179, 73–75, 79–83). Petitioner contends that, as both Lee and Fitz confirm, this would improve Racz’s device by providing an expanded and controlled energy coverage area. Id. (citing Ex. 1011 ¶¶ 9–10, Abstr.; Ex. 1010 ¶¶ 12, 84, 123–131; Ex. 1033 ¶ 179). Petitioner argues further that, in implementing Lee’s perimeter filaments (22/1622) on Racz’s distal tip (14/38), a person of ordinary skill in the art would have found it obvious to modify Racz’s tip (14/38) to include internal deflection surfaces (12/1612) (e.g., channels and ramps as disclosed in Lee) to guide the perimeter filaments (22/1622) outwardly around Racz’s tip (14/38). Pet. 41 (citing Ex. 1010 ¶¶ 16, 18, 92, 102, claims 8, 10; Ex. 1033 ¶ 180). Petitioner asserts that it would have been obvious to provide openings in Racz’s distal tip (14/38) (e.g., in communication the internal deflection surfaces as disclosed in Lee) such that Lee’s perimeter filaments (22/1622) can, when deployed, exit Racz’s distal tip (14/38). Id. (citing Ex. 1010 ¶ 92, 102; Ex. 1033 ¶ 180). Furthermore, argues Petitioner, and to preserve the functionality of Racz’s removable electrical probe (22/52) and active tip (14/38) (and consistent with Lee’s teachings) a skilled artisan would have arranged the perimeter filaments, channels, and ramps around the internal perimeter of Racz’s cannula (10/33). Pet. 41 (citing Ex. 1010 ¶¶ 91, 92, 98, 102; Ex. 1033 ¶ 181). Petitioner recapitulates that Racz’s probe (22/52) is configured to extend the full length of the cannula’s shaft (12/34) to supply RF energy to the tip (14/38) and measure tissue temperature. Pet. 42. According to Petitioner, by omitting Lee’s central filament and arranging the perimeter filaments, channels, and ramps around the inner perimeter of Racz’s cannula (10/33), a skilled artisan could have implemented Lee’s perimeter filaments (22/1622) without obstructing Racz’s cannula (10/33). Id. at 40. Petitioner contends that this modification would preserve the functionality of Racz’s electrical probe (22/52), which is needed to transmit RF energy. Id. (citing Ex. 1033 ¶ 181–182).” slip op. at 29
