“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. Accordingly, we adopt Petitioner’s definition of the level of ordinary skill in the art for purposes of this Decision.” slip op. at 12

“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. Pet. 25–27. Therefore, at this stage of the proceeding, we decline to resolve the parties’ dispute. See Vivid Techs., Inc. v. Am. Sci. & Eng'g, Inc., 200 F.3d 795, 803 (Fed.

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. Resp. 18. Patent Owner asserts that “[t]he claims and specification consistently define ‘predicted axial accelerations’ as gravitational accelerations along the device’s axes at time T, derived from the current quaternion.” Id. (citing Ex. 1001, claim 1, 17:18–30, 17:45–52). Patent Owner further submits that “because ‘predicted axial accelerations’ are computed from the current quaternion they only contain gravitational accelerations along the device’s axes.” Id. at 19 (citing Ex. 2023 ¶ 23).

“We disagree with Patent Owner’s characterization. The teaching to use quaternions instead of Euler angles comes from Bassompiere, not Dr. Sarrafzadeh. 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. Patent Owner similarly contends that Dr. Sarrafzadeh “devotes nearly twenty pages of his declaration to rewriting Bassompiere’s Euler-based equations ‘in quaternion form,’ and explaining how to convert them back to Euler angles,” and notes that “[a]s other researchers in the field have confirmed, ‘[w]hile implementing orientation tracking using quaternions provides advantages like avoiding gimbal lock, it is significantly more complex than the Kalman filer using Euler angles.’” Prelim. Resp. 32 (citing Ex. 1002, 31–51; quoting Ex. 2027, 1). Patent Owner thus contends that replacing Euler angles with quaternions “is not a ‘trivial’ substitution.” Id. at 32.

“c.

Pet. 57–63. At this stage of the proceeding, Patent Owner does not raise any arguments specifically directed to these claims. “When instituting inter partes review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” 37 C.F.R. § 42.108(a).

“device.” This term appears twice in claim 11, once in the phrase “an orientation sensor to detect rotation of the mobile communication device,” and once in the phrase “rotation of the mobile communication device detected by the orientation sensor.” Ex. 1001, 39:13–14, 39:36–38. Patent Owner argues that we should construe this term as limited to “detecting the rotation of the mobile communication device as a whole, not the movement of individual components.” PO Resp. 15–18. Petitioner disputes this, arguing that “rotation of the mobile communication device” should be construed not only to cover rotation of the device as a whole but also should “encompass[] any rotation of the mobile communication device relative to any object, including itself,” which would extend to rotation of “any component of the device.” Reply 4–5. We need not resolve this dispute to determine the outcome of Petitioner’s asserted challenges to the ’246 patent.

“On the record developed during trial, we are persuaded that Petitioner has shown by a preponderance of the evidence that Kalliola teaches “an orientation sensor to detect rotation of the mobile communication device,” where “rotation of the mobile communication device” includes rotation of the device as a whole, regardless of whether it also includes rotation of one portion of the device relative to another. Kalliola teaches “motion sensors integrated in WCD 100” that are “used to detect when WCD 100 is being moved,” as well as to detect “when user 110 moves WCD 100 too quickly for an accurate DoA estimation.” Ex. 1004 ¶¶ 84, 86. Although Patent Owner argues that Kalliola’s motion sensors do not detect rotation of the device, this is incorrect on the record as developed at trial. Kalliola teaches that the motion sensor may take “the form of a semiconductor gyroscope chip.” Id. ¶ 84. There is ample evidence that gyroscopes detect rotation. Ex. 1013, 38 (identifying as an “orientation sensor” a “[t]hree-axis gyro” and a “[d]ynamic [h]igh [r]ange [gyro]”); Ex. 1046, 49:18–20 (Dr. Feuerstein testifying that gyroscopes “can be used to detect angular velocity”); Ex. 1047 ¶ 47 (citing Ex. 1051, 170; Ex. 1053, 9) (Dr. Buehrer testifying that a person of ordinary skill in the art “would understand that gyroscopes are well-known inertial sensors that specifically detect rotational motion”).

First, Kalliola discloses “pausing a DoA estimation until the motion of the WCD is detected by the motion sensors,” then resuming “the updating of the DoA estimation” when motion is detected. Ex. 1004 ¶¶ 14, 84. Second, Kalliola discloses a “correction or compensation mode” that is “employed when user 110 moves WCD 100 too quickly for an accurate DoA estimation,” with this “increase[d] speed of the DoA estimation” being triggered by the “[i]ncreased activity detected by motion sensors in WCD 100.” Id. ¶ 86. As discussed above with respect to limitation 11(d), the detected motion that triggers either of these modes can be rotational motion of the WCD detected by a gyroscope.” slip op. at 22

“and 5 recites “means for executing.” Ex. 1001, 7:36–40, 8:35–37. The use of the term “means” creates a rebuttable presumption that 35 U.S.C. § 112 ¶ 6 applies. See Williamson, 792 F.3d at 1348. Consistent with Patent Owner’s arguments (Prelim. Resp. 36–39), the Petition does not address the presumption and, more specifically, the Petition does not provide any argument or evidence as to why the presumption is rebutted. Furthermore, even if we were to consider Petitioner’s newly presented argument that “[t]he plain and ordinary meaning of ‘means for executing a predetermined algorithm . . . ’ connotes a general-purpose processor, which is understood as structure sufficient to perform the function” (Pet. Reply 5), such argument is not persuasive as it is not supported by evidence earlier presented in the Petition or otherwise. Furthermore, even if the plain and ordinary meaning of means for executing a predetermined algorithm were a general-purpose processor, for a computer implemented means-plus-function term the corresponding structure must be the specific algorithm implemented by the processor as argued by Petitioner.

“Given the deficiencies outlined above, Petitioner has not shown that the prior art teaches or suggests creating a fingerprint at the virtual machine monitor as the challenged claims require. Thus, Petitioner has not shown a reasonable likelihood of prevailing with respect to at least one of the challenged claims. III. CONCLUSION After considering the evidence and arguments presented in the current record, we determine that Petitioner has not demonstrated a reasonable likelihood of success in proving that at least one of the challenged claims of the ’697 patent is unpatentable. We therefore do not institute trial on any challenged claims or grounds raised in the Petition.” slip op. at 10

“We disagree with Petitioner’s arguments. Claim 1 recites “a decoy computer system [that] comprises . . . a virtual machine monitor,” and “at the virtual machine monitor: . . . creating, from the stored activities, a fingerprint.” Ex. 1001, 19:4–22. Thus, the claim’s plain language requires creating a fingerprint at the virtual machine monitor, not just at the decoy system, as Petitioner asserts. When, as here, a claim term has “ordinary, simple English words whose meaning is clear and unquestionable,” we may not redraft those words to mean something different. Chef America, Inc. v. Lamb-Weston, Inc., 358 F.3d 1371, 1373–75 (Fed. Cir. 2004). Petitioner offers no explanation how one skilled in the art might read “at the virtual machine monitor” to mean at the decoy system, rather than at the virtual machine monitor. Although the claim’s plain language is decisive, we also disagree with Petitioner’s assertion that the ’697 patent’s specification because, as Patent Owner explains, the specification describes fingerprint generation inside and outside the virtual machine monitor. Sur-reply 1–2; see id. at 2 (citing Ex. 1001, 6:65–7:2, 10:13–22). Claim 1’s plain language, however, only covers the latter. Sur-reply 1–2; see id. at 2 (citing Ex. 1001, 6:65–7:2, 10:13–22). Last, Petitioner’s characterization of Patent Owner’s infringement allegations in the related district-court proceedings, even if correct, do not undermine the claim’s plain language.” slip op. at 9

Canon Kabushiki Kaisha, IPR2016-01357, Paper 19 at 15–16 (PTAB Sept. 6, 2017) (precedential). Principal among them is the first factor—“whether the same petitioner previously filed a petition directed to the same claims of the same patent.” Id. at 16. This factor has been extended to consider not only whether the petitioner is the same as a previous petitioner, but whether the petitioner has “a significant relationship” with the previous petitioner.

“independent claims’ features. The vast majority of Petitioner’s assertions are uncontested at this stage. Further, Petitioner’s evidence shows that Bennett discloses “a first network stack Application Programming Interface (API), containing at least one first call accessible to each of a plurality of device applications, the first network stack API callable by each of the plurality of device applications to open and use data packet flows via the network stack, the wireless modem, and the at least one wireless network,” which is the only limitation that Patent Owner disputes at this stage of the proceeding. See infra, Section III.2. For the sole feature missing from Bennett—i.e., application-based data usage monitoring—Petitioner presents clear and uncontested evidence, backed by multiple prior art references, that the technique and its benefits were well known, as outlined below. Petitioner also articulates, with clear support from its expert and the prior art, not just one but several reasons that would have motivated a skilled artisan to combine Vadde’s application-based data monitoring technique in Bennett. For these reasons, we determine that the merits of at least one ground raised in the Petition are particularly strong. Thus, this factor weighs against exercising discretion to deny institution.” slip op. at 9
