“Patent Owner does not offer any reason why we should deviate from the Board’s determinations in the prior IPRs that one of ordinary skill in the art would have had knowledge of Kalman filters and quaternion mathematics. Nor are we aware of any such reason. On the contrary, the Board’s prior determinations are consistent with the level of ordinary skill reflected by prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978). Bassompiere, for example, teaches using a data merging algorithm that is, “[a]dvantageously,” extended Kalman filtering. Ex. 1006, 4:17. Bassompiere also teaches using quaternions to determine a device’s pitch and roll about a horizontal reference frame. Id. at 6:3–8, 20:10–21:1. Patent Owner argues that Dr. Sarrafzadeh’s testimony regarding the level of skill in the art in this proceeding contradicts his testimony in the prior IPRs, which did not include knowledge of Kalman filters and quaternion mathematics in his definition of the level of ordinary skill in the art. Prelim. Resp. 24–26. Patent Owner asserts that this contradiction “undermin[es] his credibility.” Id. at 26. We disagree. The testimony Dr. Sarrafzadeh provided in the earlier IPRs obviously preceded the Board’s determinations in those proceedings that, on the whole record, including the testimony of then-Patent Owner’s declarant, the level of ordinary skill included knowledge of Kalman Filters and quaternions. Dr. Sarrafzadeh’s testimony in this proceeding reasonably aligns with those determinations.

The only disagreement is whether that device is a “3D pointing device” or an “electronic device.” The Specification indicates that “electronic device” encompasses 3D pointing devices as well as, e.g., smartphones and navigation equipment, and therefore is the broader term. Ex. 1001, 13:20– 23.

Paper 14, 1. Petitioner also submits in that briefing that “the term ‘axial acceleration’ (whether predicted or measured) . . . ordinarily encompasses three types of acceleration,” i.e., “linear, centrifugal, and gravitational.” Id. at 3, 4. Patent Owner contends that “predicted axial accelerations” should be construed as “[g]ravitational acceleration along the electronic device’s axes derived from the current quaternion.” Prelim.

See Ex. 1006, 20:10–11 (“A first variant embodiment consists in replacing the angles of torsion θ and ψ by a quaternion formulation of the same torsion.”). Rather than supplying a missing limitation, we understand Dr. Sarrafzadeh to be explaining how a person of ordinary skill in the art would have implemented Bassompiere’s teaching to use quaternions instead of Euler angles given that person’s knowledge of quaternion mathematics.

When read together, Petitioner’s stipulation limits Petitioner to pursue in district court a “ground on which the PTAB declines to institute an IPR trial.” This means that the Board must first have “decline[d] to institute” a “ground” in “an IPR trial” before the Petitioner would be allowed to pursue that “ground” in the “co-pending district court litigation.” In our view, Patent Owner misinterprets and overstates Petitioner’s limited reservation of rights in its Sotera stipulation. In Sotera Wireless, Inc. v. Masimo Corporation, IPR2020-01019, Paper 12 (PTAB Dec. 1, 2020) (precedential as to § II.A) (“Sotera”), the Board considered a stipulation similar to the one Petitioner now offers in its “mitigates any concerns of duplicative efforts between the district court and the Board, as well as concerns of potentially conflicting decisions,” and determined that “Petitioner’s broad stipulation ensures that an inter partes review is a ‘true alternative’ to the district court proceeding.” Id. at 19.

“An inter partes review may not be instituted “unless . . . the information presented in the petition . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a). Per Board practice, if the Board institutes trial, it will institute “on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” See 37 C.F.R. § 42.108(a). Having considered the arguments and evidence presented by Petitioner and Patent Owner, we determine that Petitioner has demonstrated a reasonable likelihood of prevailing on at least one of the challenged claims of the ’540 patent.

- Obviousness (§103) › Graham factors (scope of art, differences, level of skill)Instituted
“c) Claim 1 Analysis Petitioner has demonstrated that, contrary to Patent Owner’s arguments, Yerazunis discloses write protecting a segment of the buffer. Yerazunis explicitly states that “[upon] a firing event, specified frame data associated with that firing event both before and after the event is preserved and cannot be overwritten as a result of further use of the gun or subsequent of memory to a second portion of memory to avoid overwriting the data in the first portion of memory upon the occurrence of a second trigger event is an effective approach to designating the first portion of memory as write protected. As Petitioner points out, an ordinarily skilled artisan would have understood from Yerazunis that retrieving video data for gun firing events necessitates the ability to locate the relevant video data within the buffer and that using pointers in a table to index the data allows for its later retrieval. Pet. 25 (citing Ex. 1062, Sarhan Decl. ¶ 372). We find unavailing Patent Owner’s argument that Yerazunis’ disclosure of a purge button to erase the contents of the circular buffer is further evidence that that entire buffer contents is protected and unprotected as a whole. Prelim. Resp. 30 (citing Ex. 1017, 9:47–51). It is unclear how providing an “optional” purge feature that erases the contents of the circular buffer and captured still images a “user does not desire to retain” supports Patent Owner’s argument that Yerazunis does not disclose write protecting segments of the buffer associated with a trigger event. Ex. 1017, 9:49–53. Inclusion of this feature further supports Petitioner’s argument, as the segments of a circular buffer associated with an event are not overwritten, unless the user invokes the purge feature to erase the contents of the circular buffer. Also unavailing is Patent Owner’s argument that video data preservation in Yerazunis “is a step that occurs after, not as part of, the step of ‘continu[ing] to record for a brief interval.’” See Prelim. Resp. 30–31. Claim 1 is an apparatus claim and does not recite “continuing to record for a brief interval.” See Ex. 1060, 12:19–47 (claim 1). Claim 1 recites “a computer processor configured to . . . continuing to record the sensor data in designated for saving.” Ex. 1060, 12:22, 34–36. Yerazunis discloses that upon detection of a trigger event a predetermined number of frames, e.g., 2 frames, are stored in successive frame locations within the circular buffer. Ex. 1017, 8:26–32; 12:14–28. Yerazunis further discloses that “any desired percentage of frames may be captured prior to or after the trigger event by specifying how many frames are to be captured and stored after the trigger event.” Id. at 8:39–42.” slip op. at 21
