“understanding of a person of ordinary skill in the art at the time of the invention. Graham, 383 U.S. at 17. Dr. Ducharme testifies that a person of ordinary skill in the art “would have had at least an undergraduate degree in mechanical engineering, or equivalent education, training, or experience, with at least two years of experience with [Unmanned Aeriel Vehicles (UAV)].” Ex. 1003 ¶ 72. Dr. Reinholtz testifies that a person of ordinary skill in the art “would have had a bachelor’s degree in mechanical engineering and at least two years of experience designing mechanisms and mechanical structures of the type used in releasable couplings and locking devices. Additional education could substitute for professional experience and significant work experience could substitute for formal education.” Ex. 2001 ¶ 28. Dr. Reinholtz acknowledges that he does not view “Dr. Ducharme’s proposed definition as substantially different from [his own].” Ex. 2001 ¶ 30. We agree and note that our consideration of the issues presented does not turn on which proposed definition is applied. Dr. Ducharme and Dr. Reinholtz also acknowledge that their respective testimony would remain the same regardless of which of these definitions of a person of ordinary skill in the art is applied. See Ex. 1028 ¶ 23; Ex. 2001 ¶ 30. In any event, for purposes of this Final Written Decision, we adopt Petitioner’s description of a person of ordinary skill in the art, while maintaining our prior determination (Inst. Dec. 10) that the prior art reflects the appropriate level of skill at the time of the claimed invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).” slip op. at 12

“1. “lugs” and “notches” Claim 1 recites, inter alia, “the shaft lock portion defining notches configured to engage corresponding lugs on the blade lock portion.” Ex. 1001, 6:7–9 (emphasis Petitioner’s (Pet. 23)). In the Institution Decision, we construed “lugs” and “notches,” in accordance with Petitioner’s proposal, as “projections” and “indentations,” respectively. See Inst. Dec. 12; Pet. 24; Ex. 1003 ¶ 86. The parties do not dispute this construction in their subsequent briefing, and we discern no reason to change this construction based on the complete record of this proceeding. Therefore, we maintain our prior construction for purposes of this Final Written Decision.” slip op. at 15

“claims.” 35 U.S.C. § 316(d)(1)(B); see 37 C.F.R. § 42.121(a)(3) (“A motion to amend may cancel a challenged claim or propose a reasonable number of substitute claims.”). Patent Owner proposes two substitute claims in place of two challenged claims. Revised Mot. Amend 1, 27. “There is a rebuttable presumption that a reasonable number of substitute claims per challenged claim is one (1) substitute claim.” Lectrosonics, Paper 15 at 4; see 37 C.F.R. § 42.121(a)(3). Petitioner does not argue otherwise. See generally Opp. Therefore, we determine that the amendments propose a reasonable number of substitute claims.” slip op. at 18

“screwed onto the wrong driveshaft, when using a conventional threaded attachment mechanism (such as that described in Sasaki) is actually “mistake-proof.” Based on the evidence of record, we determine that it is not. Or, in other words, we determine that the conventional threaded attachment mechanism taught by Sasaki does not teach the Engagement Limitation (i.e., it does not prevent the clockwise lock mechanism from “be[ing] engaged in” the counterclockwise lock mechanism). According to Patent Owner, “the conventional screw-on type blade attachment mechanism does not prevent the attachment of a blade to the wrong drive.” Revised Mot. Amend 15 (citing Ex. 2001 ¶¶ 52–54, 59). Patent Owner contends that “it is relatively easy to attach a blade on the wrong drive on a UAV that utilizes the conventional screw-on type connection mechanism.” Id. (citing Ex. 2001 ¶¶ 52–54); see also Ex. 2006 (video created by Dr. Reinholtz demonstrating that a blade can be attached to the wrong drive using a screw-on type attachment mechanism). In its Reply, Patent Owner argues, again relying on the testimony of Dr. Reinholtz, that “[w]ith a conventional threaded attachment mechanism, when a blade is screwed onto the wrong driveshaft, the blade becomes engaged in the lock mechanism.” Reply 2 (citing Ex. 2016 ¶¶ 20–24). Petitioner, on the other hand, relying on the testimony of Dr. Ducharme, contends that “[w]hen a blade is forced onto the driveshaft and the threads are ‘stripped’, the blade is not, and cannot be, ‘engaged’ with the lock mechanism”; “[r]ather, the metal threads on the shaft lock portion are likely carving out new notches in the blade lock portion.” Opp. 12 (citing Ex. 1028 ¶ 49). According to Patent Owner, however, the “[i]ntent of the UAV designer is not a part of the Engagement Limitation.” Reply 2; see id. (noting that “Petitioner’s position appears to be premised on the incorrect notion that the Engagement Limitation requires the engagement of lock mechanism components in the precise way that is intended by the designer of the UAV”). Patent Owner contends that to “be engaged in,” as properly construed, “include[s] the type of connection between threads when a blade is screwed onto the wrong driveshaft.” Id. at 3. As we have construed it, to “be engaged in” merely requires “being interlocked.” See supra Section II.C.2. Relying on testimony of Dr. Reinholtz, Patent Owner further contends that “when a blade is screwed onto the wrong driveshaft, the threads on the blade mate or interlock with the threads on the driveshaft.” Reply 3 (citing Ex. 2016 ¶¶ 20, 23–24); see also Tr. 31:8–12 (“[A]s Dr. Reinholtz explains [at Ex. 2016 ¶ 23], that when a blade is misthreaded, a mechanical connection is created by engagement between the threads either because threads on the blade are deformed around threads on the shaft or threads on the shaft carved through threads on the blade.”). As shown in Dr. Reinholtz’s video, when the blades are screwed onto the wrong driveshaft, the blade and shaft are locked together (i.e., “interlocked” or “engaged”). Ex. 2006; see also Ex. 2001 ¶ 54 (describing the video, and indicating that the incorrectly installed blades “do not fall off” and are “securely attached”).” slip op. at 32
