“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. 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).

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.

“c. Conclusion as to Claim 1 Having reviewed the record and the parties’ arguments, we determine that Petitioner has a reasonable likelihood of prevailing with respect to claim 1, and therefore has satisfied the threshold requirement for institution of inter partes review on the basis of Ground 1. 3.

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).

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.

Petitioner asserts that a person of ordinary skill in the art would have also been motivated to implement Kim’s identification of “traits” and the organization of the user interface based on those traits in Darnell’s feed aggregation system. Id., ¶ 392. A POSITA would have been further motivated to implement Kim’s feed application, email application, media application, and photo application using Darnell’s server system 104 rather than on user devices, because doing so would allow users to access personalized content feeds on any user device (e.g., phone, computer, tablet, etc.) instead of only on a single user device. Pet. 16–17 (citing Ex. 1002 ¶¶ 392–395). Petitioner also asserts that a person of ordinary skill in the art would have further understood Darnell and Kim to be compatible because they disclose content feed aggregators with a similar user experience—aggregating multiple content feeds from different sources into a unified user interface displayed on a user device.

“Based on the current record, we credit Dr. Martin’s testimony and preliminarily determine that the ordinary and customary meaning of the term “real time” as it is used in the context of the ’658 patent means to provide or transmit content when it is available without significant delay. This, however, does not resolve the issue of whether, as Petitioner contends, the claims require that content must be streamed in “real time” to just a “master server,” or as Patent Owner contends, content must also be streamed in “real time” to a “master webpage.”” slip op. at 15

“1. Rationale to Combine Darnell and Kim Petitioner contends that “Darnell and Kim address similar problems of aggregating and presenting multiple feed sources to users.” Pet. 13 (citing Ex. 1002 ¶ 146). Petitioner notes, for example, that “Darnell addresses ‘[l]ooking through a dense list of content items to locate items of interest,’ which is cumbersome for users,” and Kim “similarly addresses the problem of viewing multiple pieces of fragmented content from news sources, blog entries, email, and the like in a ‘consuming experience having significant drawbacks.’” Pat. 13–14 (citing Ex. 1002 ¶ 146; Ex. 1004 ¶ 9; Ex. 1005 ¶ 1). Petitioner asserts that a person of ordinary skill in the art would have understood Kim’s teachings for aggregating news, blog entries, and email in a network computer and sending the feeds to a remote computer for display in a UI to be suitable for use with Darnell’s feed reader architecture, in which content feed sources are aggregated on a remote server instead of at the user device.

Id., ¶147.

“have a bachelor’s or equivalent degree in computer science or a related field and at least 2 years of experience in multimedia processing or delivery using internet protocols.” Pet. 10 (citing Ex. 1002 ¶¶ 67–68). Petitioner further states that “a person with less formal education but more experience, or more formal education but less experience, could have also met the relevant standard for a POSITA.” Id. Patent Owner submits a similar definition (see Prelim. Resp. 13–14), but states that a POSITA “would understand that . . . the subject of the patent is a software-based solution to broadcasting multimedia streams, and the skillset and expertise in hardware-based systems would not make one knowledgeable about software-based systems.” Prelim. Resp. 13–14. We determine that no express finding is necessary, on the present record, and that the level of ordinary skill in the art is reflected by the 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). The difference in how each party characterizes a POSITA’s work experience does not change our analysis or conclusions based on the present record.

“B. Merits 1.

A person with less formal education but more experience, or more formal education but less experience, could also meet the standard. Pet. 19 (citing Ex. 1007 ¶¶ 68–69). Patent Owner provides a different definition: A person of ordinary skill in the art at the time of the inventions in the ‘002 Patent would have had a bachelor’s degree in computer science or a related field, and at least two years of experience working in the field of software systems used in generating and broadcasting multimedia streams. An individual with less technical education but more experience, or vice versa, could also qualify as a person of ordinary skill in the art. Prelim. Resp. 12 (citing Ex. 2006 ¶ 59) (emphasis added).

“There is no dispute that (1) Avellan’s user initiates the request and eventually receives the stream and (2) gateway server 134 receives a request for a media stream for playback on a broadcast channel. See id. at 32–39; Pet. 22. The issue here is whether claim 1 requires that the recited “content provider” originates the request. We agree with Petitioner that claim 1 does not require this. Prelim. Reply 7. Apart from being received from the content provider, claim 1 does not limit the request’s origin in any way. Rather, claim 1 only requires that the request is received from the content provider. Ex. 1001, 14:51–54. Claim 1 recites “comprising” in the preamble of the method (id. at 14:50), which is a encompasses user-originated requests that are received from other entities. With this understanding of the claim, we preliminarily agree with Petitioner that Avellan discloses limitation 1a through its communication path from network 150 to user computers 1041–104n via gateway platforms 1301–130n. Pet. 22. That is, Avellan’s gateway platform 134 receives a request for at least one media stream, and claim 1 does not exclude user-originated requests. See id. We agree that the content can be video from CNN, BBC, ESPN, or other live-streaming television feeds. Id. at 24 (citing Ex. 1003, 8:18–21). Thus, at this stage and on this record, we agree with Petitioner that Avellan discloses limitation 1a. See id. at 22. ii. Remaining Limitations Apart from the arguments discussed above, Patent Owner does not present arguments specifically directed to the other limitations of claim 1. See Prelim. Resp. We determine that Petitioner’s arguments made in connection with those limitations are sufficient at this stage and on this record. Pet. 24–32. We agree with Petitioner that Avellan teaches obtaining content from the networks 150 and 152, as recited in 1b; rendering a webpage by a browser at gateway 134, as recited in 1c; generating the screen captures at gateway 134, as recited in 1d; and assembling and providing the media stream when gateway server 134 compresses the image or video format and sends it to the browser 106, as recited in 1e and 1f. Id. at 24–29. Petitioner has provided a sufficient rationale at this stage why a method with the subject matter recited in lg and 1h would have been obvious. Id. at 29– 32. Conclusion At this stage and on this record, it is reasonably likely that Petitioner would prevail in showing that claim 1 is unpatentable as obvious over Avellan. The Petition’s merits are compelling because Petitioner’s challenge plainly leads to a conclusion that claim 1 is unpatentable.” slip op. at 12
