“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 parties agree that the claimed “spatial reference frame” is associated with a device, has its origin at the same point in the device, and has axes that are always fixed with respect to the device. 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. At this stage of the proceeding, we determine that the threshold question of institution can be decided under either construction, because Patent Owner does not dispute that the primary asserted reference, Bassompiere, teaches a “spatial reference frame” associated with a 3D pointing device.

In subsequent briefing that will be discussed more fully below, Petitioner asserts that its declarant, Dr. Sarrafzadeh, “applied the ‘plain and ordinary’ meaning for all claim terms, including the ‘predicted axial accelerations’ term,” in this proceeding. 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. Patent Owner also argues that “switching from Euler angles to quaternions is not a routine substitution but requires the reengineering of the EKF.” Prelim. Resp. 28.

Ex. 1001, 4:51–57. On this preliminary record, we agree with Petitioner that the term “link data” is a “connection relationship between the P2P devices.” This meaning is consistent with the ordinary meaning of the term within the context of the claim, that is, “link data” means data on the links (connections) between each of the P2P devices, where the Specification provides a more fulsome meaning that the term includes, at least, “the connection structure, connection data and/or locations of connection.” See id. at 4:55–57.

Cisco Systems, Inc., No. 2:24-cv-00332 (E.D. Tex.)) any ground on which the PTAB declines to institute an IPR trial. Id. (emphasis added). 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.

“We are persuaded by Petitioner’s arguments and evidence. Fuloria teaches “a mechanism for user to promote social networking objects to other users.” Ex. 1004 ¶ 1. Fuloria displays a news feed containing social media content items. Id. at code (57), ¶¶ 6, 27. Users in Fuloria may like a piece of content or “for a given price” the user may turn their like into a “super-like.” Id. ¶ 37. “The ‘super-liked’ story is priced and directed toward users in a similar manner as a social ad. In particular embodiments, sponsored story system 304 may also add a weight to the story to alter its direction toward users.” Id. ¶ 39. Petitioner argues that “[t]his functionality represents uncapped engagement . . . because Fuloria places no limitation on how many times a user can super-like a piece of content.” Pet. 24–25. Dr. Bederson supports Petitioner by noting that Fuloria does not “place any limitation on how many credits a user can spend to increase the reach of the content.” Ex. 1002 ¶ 76. Further, Dr. Bederson states that “[m]ultiple different users can also promote the same content item. By allowing users to promote or ‘super-like’ content which also increases engagement with that content by other users, Fuloria’s system also facilitat[es] uncapped engagement with that content.” Id. ¶77. We find these arguments to be persuasive. The ’687 patent states that “[s]o long as the user has sufficient resources, the user may promote herself or others with uncapped (i.e., unlimited) engagements, which may facilitate getting noticed by other users, whether with respect to a social media content item.” Ex. 1001, 2:6–10. Similarly, Fuloria allows users to expend their resources and to have the super-like displayed according to the amount paid for the super-like. Ex. 1004 ¶ 57 (“In particular embodiments, the advertisement system adjusts the display of the ‘super-liked’ story based upon social factors as well as the real-world value of the credits paid.”); see also id. ¶ 38 (“[T]he social networking system may deduct the credits based on a cost per impression (CPM), effective cost per impression (eCPM), cost per click (CPC), or cost per action (CPA) pricing model”). Fuloria teaches likes from any number of users which is argued to disclose the multiple users recited in the claim. See Ex. 1002 ¶ 82 (discussing Fuloria’s display of engagement by a user and pointing out that Figure 9A shows 1,884 likes); see also id. ¶ 87 (“Fuloria teaches that ‘super-likes’ are available to users in general (and thus to first, second, third, etc. users).”).

“If, at the time of the institution decision, the district court has not issued orders related to the patent at issue in the petition, this fact weighs against exercising discretion to deny institution . . . .” Fintiv, Paper 11, 10.

“that the combination of interlayer 160, gate insulating layer 140, and buffer layer 120 (plus additional layers in display area 200 of Kwak’s flat-panel display) cannot be considered the claimed predetermined material layer, but rather that Petitioner has not explained why they should be so considered. See Prelim. Sur-reply 2 (“[I]t is presumptively permissible to have multiple predetermined material layers as claimed . . . . [b]ut the Petition included no theory or explanation why the three to six separate layers in its theory form a predetermined material layer.”). We agree that Petitioner does not offer an express construction of “predetermined material layer.” At this point, however, we find little in either the claims, the Specification, or elsewhere in the record that limits the meaning of “predetermined material layer” in a way that would exclude the combination of interlayer 160, gate insulating layer 140, and buffer layer 120. The Specification does not expressly define “predetermined material layer” or “predetermined material,” and we have found no evidence in the record that “predetermined material layer” or “predetermined material” has a known meaning in the art, or that otherwise supports Patent Owner’s reading of those terms. Further, we find nothing in the claims or Specification that limits “material” to any specific materials. The Specification provides several nonlimiting examples of materials that can be used if the predetermined material layer is to serve as a passivation layer, and several other (or additional) materials that can be used if the predetermined material layer is to serve as a metal electrode layer. Ex. 1001, 2:47–55. Thus, in view of the Specification, a “predetermined material layer” would simply be a layer made of one or more predetermined materials. In light of Patent Owner’s acknowledgement that “a layer” can mean “one or more layers,” the term “predetermined material layer” would encompass the combination of interlayer 160, gate insulating layer 140, and buffer layer 120.” slip op. at 23
