    “Kwatra teaches, at Equation 7, minimizing velocity and acceleration of a function representing camera path (P). FF ¶¶ 6, 8–9. Kwatra does not state that this camera path function considers rotation. Rather, the words “camera path” suggest x, y, z movement of the camera rather than rotation of the camera. Dr. Foroosh’s testimony that Kwatra’s minimization of a smoothed camera path does not result in minimizing rotational velocity and acceleration is credible because this testimony is consistent with Kwatra as a whole and consistent with the other evidence of record. Id. ¶ 10. Kwatra recognizes that image rotation angle (“θ”) may not remain smooth. Id. ¶ 12. But rather than attempting to minimize velocity and acceleration of rotation of the camera housing, Kwatra states that applying a smoothness constraint on rotation angle “may be non-linear.” Id. ¶ 13. Consistent with Kwatra, Dr. Foroosh credibly explains the difficulty of applying linear techniques to rotation. Id. Thus, Kwatra proposes instead constraining the sine and cosine of theta. Id. ¶ 14. The Kwatra provisional application is part of the Kwatra reference (id. ¶ 15), and it similarly opts for simpler schemes rather than estimating all parameters for all frames jointly. Id. ¶ 16. The provisional explains that the rotational component is relatively small such that non-linear computations minimizing velocity and rotation can be avoided. Id. ¶¶ 17–18. The testimony of Patent Owner’s witness, Dr. Foroosh, explaining the provisional is credible (Ex. 2018 ¶ 72) because it is consistent with Kwatra’s complete disclosure. Dr. Foroosh’s testimony is more credible than the testimony of Petitioner’s witness, Dr. Katsaggelos, because Dr. Katsaggelos did not review the Kwatra provisional application and, thus, did not review the entire disclosure of Kwatra.

Cir. 1985) (“Lack of factual support for expert opinion going to factual determinations, however, may render the testimony of little probative value . . ..”). Here, the underlying factual basis is not very strong for either witness. That said, we find that Dr. Foroosh’s testimony is more logically sound and consistent with the ’840 patent disclosure. Based on our reading of the specification, we find a clear indication that “stickiness” has to do with the past. In order to control “the extent by which preceding portion(s) . . . impacts determination of the smoothed trajectory” (emphasis added), one must control the degree by which the past frames impact determination. And to control the degree of the past’s influence, one must, as a consequence, favor the past over the future. That is, the frame of reference of the stickiness parameter is the past. The specification could have used a time-agnostic term, like a “nearness” or “adjacency” parameter, but it did not. Thus, the fact that “stickiness” is used in conjunction with “preceding” indicates that it deals with a preference for preceding frames. On this basis, we find Dr. Katsaggelos’s testimony less persuasive than Dr. Foroosh’s.” slip op. at 10

    “That said, we do not construe a stickiness parameter as prohibiting consideration of future frames. Instead, we determine that the stickiness parameter’s value determines the impact of the preceding portions, versus the following portions. The ’840 patent recognizes this, when it says that a stickiness parameter value of “1,” representing a “lazy” stabilizer that maximally favors the past, would not override a violation of the margin constraint based on the look-ahead (i.e., would not allow the viewing window to fall out of bounds in the event of large future motion). See Ex. 1001, 22:26–30; see also id. at 12:61–13:29 (acknowledging that favoring the past may lead to a conflict with the viewing window determination), 15:39–60 (adjusting the viewing window to ensure it does not violate a margin constraint). Thus, while a past-favoring parameter by necessity favors the past over the future, it does not prohibit consideration of the future. In view of the above, we construe the claimed “stickiness parameter” as a parameter that controls the extent by which preceding portions of the trajectory impacts determination of the smoothed trajectory, with an understanding that in order to favor preceding portions, to some extent, the parameter must relatively disfavor following portions.” slip op. at 10

Asserting that “Mauer teaches providing sufficient network coverage by use of different kinds of networks, network interfaces, and protocols,” Petitioner contends that a person of ordinary skill in the art would have recognized that “Waylett discloses an inexpensive way to implement the same networks used in Mauer’s WWAN 14 and WLAN 12.” Id.

    “Owner that our construction in the Decision to Institute is overly broad to the extent it encompasses a synchronization frame. Petitioner relies heavily on column 5, lines 50 to 52 of the ’404 patent, but that disclosure does not unambiguously support Petitioner’s proposed construction. The paragraph, which we reproduce below for context, describes “normal (non-sleep mode) operation”: During normal (non-sleep mode) operation, a phase-lock loop (PLL) 62 receives from the FFT 56 a timing reference signal 62a (see FIG. 1A) via a line 62b. The timing reference signal 62a is transmitted from the transmitter with which the receiver 16 communicates (e.g., the CO transmitter). This signal is advantageously a pure tone of fixed frequency and phase which is synchronized with the Master Clock in the transmitter; its frequency defines the frame rate of the transceivers. Other forms of timing signal may, of course, be used, but use of a pure tone has the advantage of simplicity and reliability even when portions of the transceiver are powered down in accordance with the invention. The PLL 62 locks itself to this signal and drives clock 30 in synchronism with the Master Clock in the driving transmitter. This also synchronizes frame counter 34 of the CPE transceiver to the corresponding frame counter of the CO transceiver. Control of the receiver section is provided by the controller 32. Ex. 1001, 5:37–53 (emphasis added to 5:50–52). Rather than read “this” as referring to timing reference signal 62a, as Petitioner contends, we read “this” as referring to what is disclosed in the preceding sentence—i.e., driving clock 30 in synchronism with the Master Clock in the driving transmitter. The synchronism of clock 30 with the Master Clock in the driving transmitter is what “synchronizes frame counter 34 of the CPE transceiver to the corresponding frame counter of the CO transceiver.” Ex. 1001, 5:50–52.” slip op. at 7

We have not adopted that construction, however, for the reasons discussed above. Because our construction of “synchronization signal” excludes a synchronization frame, we are not persuaded that the argument and evidence in the Petition shows that the combination of Bowie, Vanzieleghem, and ANSI T1.413 teaches transmitting/receiving, in full power mode, a “synchronization signal.” Moreover, we agree with Patent Owner that Petitioner’s reliance, in the Reply, upon the teachings of a pilot tone in Vanzieleghem and ANSI T1.413 constitutes a change in theory and, therefore, is beyond the scope of a proper reply.

We, therefore, do not address whether the pilot tone taught in Vanzieleghem and in ANSI T1.413 teaches the recited “synchronization signal.” As a result, Petitioner has not shown, by a preponderance of the evidence, that claims 1–20 would have been obvious over Bowie, Vanzieleghem, and ANSI T1.413.” slip op. at 15

    “First, we give no credit to Dr. Chao’s opinion in this regard because it is not supported by Spinney. Specifically, we give no weight to Dr. Chao’s opinion that “Spinney makes clear that the CAM lookup and the hashing function (i.e., the forwarding lookup) take place at the same time.” Ex. 1002 ¶ 53. Instead, we find that the parallel operations in Spinney are confined to (1) applying the hash function to the 48-bit address and (2) performing a CAM lookup of the same 48-bit address. For example, Spinney discloses in Figure 8 that incoming address field 85 is subjected to hash function 86 to produce another 48-bit value. See id. at Fig. 8, 15:21−24; 16:16−19 (“The 48-bit destination address 61 from an incoming packet is simultaneously subjected to the hash function 86 and a CAM match” (emphasis added)), 16:44−46 (“this compare in the CAM is done in parallel with the hash function” (emphasis added)). The application of the hash function and the performance of the hash lookup are two different operations that produce different results. The hash function application produces a hashed 48-bit value, while the hash lookup results in pointing to an entry in the translation table that includes the gigaheader information, for processing the packet. See id. at Fig. 8 (identifying hash function 86 applied to input address 85, resulting in hashed address 89); 15:60−63.

Specifically, we give no weight to Dr. Chao’s opinion that “Spinney makes clear that the CAM lookup and the hashing function (i.e., the forwarding lookup) take place at the same time.” Ex. 1002 ¶ 53. Instead, we find that the parallel operations in Spinney are confined to (1) applying the hash function to the 48-bit address and (2) performing a CAM lookup of the same 48-bit address. For example, Spinney discloses in Figure 8 that incoming address field 85 is subjected to hash function 86 to produce another 48-bit value. See id. at Fig. 8, 15:21−24; 16:16−19 (“The 48-bit destination address 61 from an incoming packet is simultaneously subjected to the hash function 86 and a CAM match” (emphasis added)), 16:44−46 (“this compare in the CAM is done in parallel with the hash function” (emphasis added)). The application of the hash function and the performance of the hash lookup are two different operations that produce different results. The hash function application produces a hashed 48-bit value, while the hash lookup results in pointing to an entry in the translation table that includes the gigaheader information, for processing the packet. See id. at Fig. 8 (identifying hash function 86 applied to input address 85, resulting in hashed address 89); 15:60−63. Spinney further discloses that the hash lookup is performed only if a CAM match is not found and, therefore, must occur after the CAM lookup is performed.

For example, column 2, lines 42–48 and 51–55 certainly disclose that “volume” is desirable, but does not provide any equivalence between “three dimensional information” and “volume.” Indeed, column 2, lines 54–55 disclose “provide information regarding the location of soft-tissue target volumes,” indicating that “information” is a subset of “volume.” In another example, column 3, lines 40–43, mentions “three-dimensional (3- D) images,” which we agree would appear to require “volumetric” data; however, the claim limitation at issue is the broader term “three dimensional information.” In a further example, column 9, line 62, through column 10, line 5, clearly refers to “volumetric data,” but does not indicate its relation to “three dimensional information.” In yet another example, column 16, lines 43–45 and 58–62, do not recite “three dimensional information,” instead disclosing “3-D structure” and “3-D nature” in relation generally to “volumetric data,” but, again, not in a manner sufficient to indicate a particular relationship. Finally, in regard to assertions set forth in the Declaration of Dr. Hashemi, we discern some merit in his assertion that when reading the claim limitation “three dimensional information” in conjunction with another claim limitation “cone-beam computed tomography,” “a CBCT image is a volumetric image that provides the location, shape, and spatial orientation of the target volume in all directions, not just its length, width, and depth.” Ex. 2080 ¶ 85. The claim limitation at issue, however, reads “an image of said object, wherein said image contains at least three dimensional information of said object based on one rotation of said x-ray source around said object” (emphasis added). Accordingly, the claim limitation does not preclude an image having more information than “information concerning three dimensions of an object (such as length, width, and depth),” such as “a volumetric image of an object generated by reconstructing 2-D projection images.” Under Patent Owner’s construction, however, the image would be required to have such information. We are unpersuaded that such information is required under a proper construction of “three dimensional information” for the reasons set forth supra. We construe “three dimensional information” as “information concerning three dimensions of an object (such as length, width, and depth).”” slip op. at 7

    “Owner that the ’590 Application provides sufficient written description support for “controlling [said path of / a radiation therapy treatment plan involving] said radiation source based on said image.” In particular, we credit the testimony of Dr. Hashemi that a person of ordinary skill in the art would have understood from the ’590 Application that components of the disclosed system were computer-controlled based upon, e.g., the depiction of an Elekta SL-20 in Figure 3 of the ’590 Application and from the depiction of an electronic portal imaging device. (Ex. 2080 ¶¶ 109–116, 125–132). Petitioner’s arguments are not persuasive because, even assuming that controlling the source path and controlling a radiation therapy treatment plan are “an entirely different class of control step” from controlling patient position (Pet. Reply 8–9), Petitioner has not explained why the portions of the ’590 Application relied upon by Patent Owner do not disclose controlling the source path or controlling a radiation therapy treatment plan.” slip op. at 19

    “[t]he content and nature of the printed publication, as well as the circumstances surrounding its publication” (Katz, 687 F.2d at 455), we are not persuaded that Petitioner has met its burden of persuasion by showing sufficiently that the portions of Jaffray 1999 SPIE and Jaffray 1999 JRO on which it relies are the work “others.” Unlike in Katz, where the question was “the sufficiency of applicant’s showing to establish that the subject disclosure was his original work, and his alone” (687 F.2d at 455), the question before us is the sufficiency of Petitioner’s showing to establish that the subject disclosure was the work of the non-inventor coauthors of Jaffray 13 Both the burden of production and the burden of persuasion. 14 At oral argument, counsel for Petitioner indicated that, in his view, it does not matter who has the burden.
