“Petitioner argues that a person of ordinary skill in the art (“POSITA”) relating to the ’090 patent would have had “a bachelor’s degree in mechanical engineering or a related field, and at least 2 years of experience with industrial equipment design and development.” Pet. 3 (citing Ex. 1002 ¶ 29). Petitioner further contends that one of ordinary skill “may also have a combination of more formal education and less work experience or a combination of less/different formal education and more work experience.” Id. In the Patent Owner Response, Patent Owner states that it “does not object to the defined level of skill in the art.” PO Resp. 12 (citing Pet. 3). appears consistent with the problems addressed in the ’090 patent and the prior art.” slip op. at 9

“challenge, the crux of the parties’ dispute revolves around the limitation in claim 1 of “an axial region of the shaft body extending from the second end and being tapered relative to a longitudinal axis of the shaft.” We agree with for the tapered axial region and that starting point would be the extremity of the shaft not an undefined point in the “end region.” Because Patent Owner proposes a construction of “end” that would have general application to all claim terms including the first end of the shaft, the second end of the shaft, and the sleeve end, and that construction has no bearing on the issues we address below, we do not reach Patent Owner’s proposed general construction of “end” by itself. We determine that no other claim terms require express construction for purposes of this Decision. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (noting that “we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’”) (citing Vivid Techs., Inc. v. Am.

“This paragraph discusses “accurate alignment” in connection with joint 21, not tapered end 25. Ex. 1018, 3:23–35. The paragraph subsequently states that both joint 21 and end 25 are tapered but that shaft end 25 may alternatively be cylindrical. Id. We also find nothing in this paragraph supporting Petitioner’s assertion that alignment “is notoriously more difficult with purely cylindrical shafting” (Pet. 16–17). In order to support its position, Petitioner improperly conflates separate statements in this paragraph of Piepho, i.e., joint 21 provides accurate alignment, joint 21 is tapered, and end 25 is tapered. Petitioner makes an unsupported logical leap that the result of these three statements is that tapered end 25 provides accurate alignment. However, Petitioner fails to reconcile this argument with the final sentence in this paragraph that shaft end 25 may also be cylindrical as shown in Figure 4. Figure 4 “is an external view of another embodiment of” Piepho’s shaft. Ex. 1018, 2:49–50. In Figure 4, joint 21 has the same tapered configuration as shown in Figure 3 but end 25 is not tapered. Based on our review of Piepho’s Figures 3 and 4, we find that Piepho’s reference to “accurate alignment” refers to joint 21 and not to tapered end 25 as Petitioner alleges. Because Mr. Smith’s testimony (Ex. 1002, 59) essentially parrots the Petition on this point and is inconsistent with our finding, his testimony is entitled to little, if any, weight. For the foregoing reasons, we find that Petitioner has not established that a person of ordinary skill in the art would have been motivated to would teach this claim limitation.8 Because Petitioner has not shown that the combination of Polinski and Piepho teaches limitation 1b or an adequate motivation to combine, Petitioner has not shown by a preponderance of the evidence that claim 1 is obvious over Polinski, Piepho, and Harless.” slip op. at 27

“[c]ombin[e] the tapered region of Piepho with the shaft of Torrence, the tapered region would extend from an uppermost extremity of the shaft.” RMTA Opp. 9. But, Petitioner concedes that neither reference discloses a tapered region extending from the uppermost extremity. Petitioner argues that Torrence’s shaft is straight (Amended RMTA Sur-reply 9) and that “[t]he tapered region of Piepho does not extend to the extreme end of the shaft.” RMTA Opp. 11 (emphasis added). Because neither Torrence nor Piepho discloses a shaft with a tapered region that “extends from an uppermost extremity of the shaft,” we find that the combination of Torrence and Piepho does not teach limitation 11[a]. We now analyze whether Petitioner provides reasoning with a rational underpinning why a person of ordinary skill in the art would have been motivated to modify Torrence with Piepho to extend Torrence’s taper from the upper extremity of its shaft. slip op. at 22

“Patent Owner does not contest Petitioner’s combination of Polinski and Piepho, but instead argues that no motivation to combine exists because Harless “would render both Polinski and Piepho inoperable for their intended purpose of preventing shaft failure.” Prelim. Resp. 22–31 (citing, inter alia, Ex. 2001 ¶¶ 48–59). When addressing intended purpose, Patent Owner argues that “Polinski mitigates shaft fatigue failure . . . specifically by omitting threads that are typically cut into gyratory shafts to attach a crusher mantle.” Id. at 23 (citing Ex. 1017, 1:61–67). Patent Owner asserts that Polinski instead teaches that shaft stress can be reduced “by cutting threads into a bearing sleeve.” Id. at 24 (citing Ex. 1017, 1:1–67). Piepho, according to Patent Owner, seeks a similar goal: “to prevent fretting wear and corresponding fatigue,” by “coating a portion of the shaft fit into a yoke bushing (which Petitioner alleges is a sleeve) with a ceramic coating.” Id. at 24 (citing Ex. 1007, 2:15–25; Ex. 2001 ¶¶ 42–43). Patent Owner argues that introducing Harless’s groove onto the main shaft would undermine the purposes of Piepho and Polinski because these would “introduce stress concentrations,” “lead to increased fretting wear,” and “increase the likelihood of fatigue failure.” Id. at 24–29. Patent Owner also argues that Petitioner’s approach relies on impermissible hindsight because one of ordinary skill would not seek to rely on Harless’s grooved shaft for use in “mounting of gears and similar components” rather than “for crushing applications, much less in a gyratory crusher, as claimed.” Id. at 30. According to Patent Owner, Harless fails to disclose “that its shaft is subjected to the same substantial stresses generated by the cyclic loading as the shafts disclosed by Polinski and Piepho.” Id. As to Petitioner’s argument that a POSITA would be motivated to make the combination to simplify the equipment and process for interference fits, Patent Owner contends that “Petitioner impermissibly picks and chooses aspects of the three references” and ignores what they teach to a POSITA, namely that “Polinski and Piepho are both directed to mitigating shaft fatigue” and adding Harless’s oil groove introduces several problems, as noted above. Id. at 31 (citing Ex. 2001 ¶¶ 48–59). Based on the current record, Petitioner sufficiently establishes for the purposes of institution that one of ordinary skill in the art would have been motivated to combine Piepho, Polinski, and Harless in the manner Petitioner proposes. Notably, Patent Owner does not directly contest Petitioner’s stated reasons why a POSITA would be motivated to make the proposed combination, i.e., that the combination would save money and simplify the equipment and process for making and breaking interference fits. See Pet. 19–21; Prelim. Resp. 22–31. Patent Owner instead suggests that Petitioner improperly ignores disadvantages when adding Harless’s groove to Polinski and Piepho, which at best suggests a weighing between the advantages Petitioner contends the addition of Harless’s groove provides and the alleged disadvantages. See Prelim. Resp. 22–31. While Patent Owner’s arguments may ultimately prevail, given the highly factual nature of the competing expert testimony and the weighing necessary to resolve this issue, we view the issues as best resolved after further development during trial and after Petitioner has the opportunity to respond to Patent Owner’s arguments and evidence. On this record and at this stage of the proceeding, Petitioner’s arguments and supportive declarant testimony adequately establishes a motivation to combine the references.” slip op. at 17

According to Patent Owner, “Petitioner cannot on the one hand argue that a ‘POSITA would have understood that Larsen’s applicator is configured to uniformly illuminate a treatment surface of the patient,’ while on the other ignore Larsen’s teaching that the ‘light sources 17 are placed in regular row arrangements.’” Id. 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 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.

“We agree with Patent Owner that testimony from a “custodian with any personal knowledge of arXiv.org or its regular practices” would have strengthened Petitioner’s argument that Gloor is prior art.

We find that, for purposes of institution, Petitioner has met its burden to show a reasonable likelihood that Gloor was publicly accessible before the priority date of the ’200 patent. To prevail in this inter partes review, Petitioner must meet the preponderance of the evidence standard. See 35 U.S.C. § 316(e).
