    “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.

    “We review this testimony based on the strength of the underlying factual basis. 37 C.F.R. § 42.65(a); Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 294 (Fed. 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

    “Given the teachings of the specification, we agree with Patent Owner that a low-light high-pass parameter is a parameter of a smoothing function that favors high frequencies (high pass) when exposure times are long (low light). See Tr. 42:10–18 (Patent Owner’s counsel stating that “high-pass” means “there’s a bias or preference for high frequencies”); Ex. 2020, 93:23– 94:15 (Petitioner’s declarant, Dr. Katsaggelos, agreeing that a high-pass system attenuates the low frequency of a signal). Although we acknowledge Petitioner’s position that the specification provides other ways or considerations in implementing a smoothing function, based on our above analysis of the specification, we find that the specification describes the lowlight high-pass parameter as a specific component of a smoothing function. See, e.g., Ex. 1001, 21:17–25 (setting out several parameters besides the low-light high-pass parameter used in trajectory smoothing).” slip op. at 10

    “position and a real device position. Id. at 18:27–40. In other words, the blur is addressed by analyzing the image to identify motion and then shifting the image. Shi, however, does not disclose how its parameter is based on low light (or the long exposure times indicative of low light). In its Petition, Petitioner asserts that a person of ordinary skill in the art would understand that “blurs can be caused by low light conditions.” Pet. 28 (citing Ex. 1003 ¶ 111). Although this is true, that does not mean that Shi’s blurs are identified by a parameter that considers low light. As we just described, Shi identifies the blur by quantifying the amount of motion of the points in an image, not by identifying low light. This is simply a different way to determine the presence of motion blur. In Shi, blur is measured, whereas in the ’840 patent, it is inferred based on low-light conditions (e.g., by observing the exposure time). See, e.g., Ex. 1007, 18:7– 26; Ex. 1001, 19:12–26. In its Reply, Petitioner does not point to any further disclosures. Accordingly, we find that Shi does not disclose the “low-light” aspect of the claimed low-light high-pass parameter. This is sufficient to determine that Petitioner’s ground does not meet all claim limitations. Similarly, we find that Shi does not disclose the “high-pass” aspect of the parameter. Shi’s blur compensation uses a spherical interpolation to modify the image. Ex. 1007, 18:27–40. The low-light high-pass parameter, as we have construed the term, allows more high frequencies. To allow more high frequencies, this necessarily means either allowing fewer low frequencies, or allowing more high frequences as opposed to some counterfactual situation in which fewer high frequencies were going to be allowed. See Ex. 2020, 94:23–95:15; Ex. 2022. We are directed to no persuasive evidence from Petitioner that Shi’s spherical interpolation favors high frequencies over low frequencies. Accord Ex. 2018 ¶ 107 (Patent Owner’s expert stating that Shi’s spherical interpolation “reintroduce[es] both high- and low-frequency motion”). Even if Shi allows the viewing window to track the camera position “consistent with the natural blur in the image” (Ex. 1007, 17:63–67), we are not provided with sufficient evidence to conclude by a preponderance of the evidence that providing a similar visual goal as a high-pass parameter (Ex. 1001, 22:16–18, “the output motion may include high frequencies that mask motion blur”) is the same as having a high-pass parameter. Again, merely preserving high frequencies is not the same as having a “high-pass parameter” because, as construed, a “high-pass parameter” also involves some degree of attenuation of low frequencies or relative increase of high frequencies. Accordingly, we find that Shi does not disclose the “high-pass” aspect of the claimed low-light high-pass parameter.” slip op. at 18

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

    “a) Combination of Mauer and Waylett In support of both Ground 1 and Ground 2, Petitioner argues that a person of ordinary skill in the art would have been motivated to combine Mauer’s and Waylett’s disclosures, “using Waylett’s Network-in-a-box 224 in each of Mauer’s WWAN 14 and WLAN 12, resulting in at least two DMA systems.” Pet. 11–13. 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. Citing similarities in Mauer’s and Waylett’s systems, Petitioner argues that “a POSITA would have been able to modify Mauer’s WWAN 14 and WLAN 12 networks so that each network uses Waylett’s NIB 224.” Id. at 14. According to Petitioner, the combination would have included a number of beneficial features from Mauer. Id. at 14–15. Petitioner further advances three reasons that a person of ordinary skill would have had to combine the references’ teaching. Id. at 15–16. First, asserting that Waylett discloses cost benefits and Mauer discloses “an improved method and system for notifying mobile stations,” Petitioner contends the “references each provide reasoning” to combine their disclosures. Id. at 15. Second, Petitioner argues that a person of ordinary skill in the art would have been motivated to “improve Mauer’s distributed wireless network system by consolidating it into a single box, making it compact in design allowing for faster deployment.” Id. at 16. “Third, Waylett’s NIB would help mitigate the shared concern of Mauer—that is, reaching a mobile station as it roams or moves outside of the service or coverage area.” Id.” slip op. at 24

    “Petitioner does not establish that Mauer sends calls to voicemail based on the two determinations claim 1 recites. Resp. 55–56. In particular, as we explain above, claim 1 requires making use of the DPR after first determining the second mobile subscriber is not located within a first wireless coverage area based on HLR and VLR information and also determining that the second mobile subscriber is not located within a second wireless coverage area based on certain CLR information. The Petition, at best, attempts to establish that Mauer directs to voicemail when a “communication session cannot be established over the first or second wireless network.” Pet. 37. But a general determination that a “communication session cannot be established” does not teach or suggest claim 1’s specific requirements that first, the DPR is utilized in the specific circumstance that the second mobile subscriber is not located within the first wireless coverage area (with this determination being made based on HLR and VLR information), and second, that the DPR is also not located within the second wireless coverage area (with this determination being made based on CLR information).

    “Petitioner’s proposal is too broad. PO Resp. 8. For example, a person who merely installs solar panels for three years (satisfying “professional experience in solar energy”) while having some familiarity with module manufacturing would not be of ordinary skill in the design aspects of the ’060 patent as, for example, reflected by the claims at issue and the ’060 patent’s text and figures. See, e.g., Ex. 1101, Figs. 2a, 2b, 3a, 3b, 4a, 4b, 3:22–7:44. On the other hand, we also determine that Patent Owner’s proposal is too narrow. A person could, for example, have ordinary skill in the art of the ’060 patent by virtue of non-professional experience (for example, academic experience). When assessing relevant experience, research work done for a university (beyond mere classroom study) would have been just as valuable as research work done for a corporation. Also, ordinary skill in the art could be demonstrated by work that requires understanding of the ’060 patent’s field even if not “designing, developing, and/or researching” in the field itself We, thus, determine that a person of ordinary skill in the art of the ’060 patent would have been someone with a bachelor’s degree in electrical engineering, applied physics, or the like, and at least two years of (a) experience designing, developing, and/or researching in the field or (b) experience in solar energy that required an understanding of the ’060 patent’s field.

  • Strike new argumentNew argument disregardedDecided for patent owner

    “Our rules require that a petition include “[a] full statement of the reasons for the relief requested” and that “[a] reply may only respond to arguments raised in the corresponding . . . patent owner response.” 37 C.F.R. §§ 42.22(a)(2), 42.23(b). The trial practice guide elaborates on these rules, explaining that “Petitioner may not submit new evidence or argument in reply that it could have presented earlier, e.g. to make out a prima facie case of unpatentability.” Consolidated Trial Practice Guide November 2019 (“CTPG”)13 at 73. “While replies . . . can help crystalize issues for decision, a reply . . . that raises a new issue or belatedly presents evidence may not be considered. The Board is not required to attempt to sort proper from improper portions of the reply . . . .” Id. at 74. As one example of impermissible new argument or evidence, the trial practice guide identifies a “newly raised rationale to combine the prior art references that was not expressed in the petition.” Id. Applying the foregoing legal authority, we agree with Patent Owner that Petitioner’s Reply improperly introduces new argument and new evidence. As discussed above, Petitioner changed its obviousness theory from one that relied on combining Hochstein’s or Masatoshi’s LEDs with Krames’ TIP geometry and Rossner’s phosphors, as asserted in the Petition 13 Available at https://www.uspto.gov/TrialPracticeGuideConsolidated. Krames’ TIP geometry and Rossner’s phosphors, as asserted in the Reply (Pet. Reply 7). GaN-on-SiC LEDs are not disclosed in Hochstein, Masatoshi, or any of the other references asserted in the Petition. As support for its contention that GaN-on-SiC LEDs were known, Petitioner relies on two new references—the ’499 patent and the Cree article—that were not cited in the Petition or the Shackle Declaration. Petitioner argues that its reply argument and evidence are not new, but were presented to “show[] that Patent Owner’s statements were false and contrary to what was known in the prior art; namely, that you can cut the substrates related to GaN-based LEDs, specifically, silicon carbide substrates, using a beveled blade.” Tr. 34:4–8. We disagree. The Petition relied on Hochstein in view of Krames or Masatoshi as teaching “a light emitting cell array . . . comprising a plurality of light emitting cells connected in series on a substrate,” as recited in claim element 1a. Pet. 36–37, 54–55. In its Response, Patent Owner argued that the LEDs disclosed in Hochstein, Masatoshi, or Krames would not work in Petitioner’s proposed combination with Rossner. PO Resp. 17. In the Reply, Petitioner agreed with Patent Owner, asserting for the first time that GaN-based LEDs, more specifically GaN-on-SiC LEDs, would have been used. Pet. Reply 2, 7. To show that GaN-on-SiC LEDs were in the prior art, Petitioner relied on two new references: the ’499 patent and the Cree article. Exs. 1035, 1058. Rather than explaining how its original petition was correct, Petitioner’s reply argument and evidence “amount to an entirely new theory of prima facie obviousness absent from the petition. Shifting arguments in this fashion is foreclosed by statute, our precedent, and Board guidelines.” Wasica, 853 F.3d at 1286. determination that Petitioner failed to prove that claims 1, 3, and 4 of the ’946 Patent are unpatentable. Petitioner abandoned its original theory of obviousness and presented a new theory of obviousness based on new evidence in the Reply. Under our rules, this is procedurally improper and leaves us with no properly presented ground of unpatentability on which we could hold for Petitioner. 37 C.F.R. § 42.23(b); CTPG 73–74.” slip op. at 28

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundNot shown unpatentable

    “4. Obviousness Rationale As presented in the Reply, Petitioner’s new obviousness theory requires a combination of Hochstein’s driving circuit, Rossner’s storage phosphors, Krames’ TIP geometry, and GaN-on-SiC LEDs, as disclosed in the ’499 patent or the Cree article. See Pet. Reply 7 (arguing that Krames’ TIP geometry could have been implemented in GaN-on-SiC LEDs). Alternatively, Petitioner’s new obviousness theory requires a combination of Masatoshi’s circuit, Rossner’s storage phosphors, Krames’ TIP geometry, and GaN-on-SiC LEDs, as disclosed in the ’499 patent or the Cree article. Id. Petitioner does not, however, present a sufficient evidence-supported rationale for combining GaN-on-SiC LEDs with either Hochstein’s driving circuit or Masatoshi’s circuit. No such rationale is presented in the Petition or the Shackle Declaration, which do not mention GaN-on-SiC LEDs. Although Petitioner’s Reply and the Krames Declaration discuss GaN-on- SiC LEDs, neither document explains why a POSITA would have had reason to combine them with Hochstein’s driving circuit or Masatoshi’s circuit. In fact, the Krames Declaration makes no mention of either has not provided sufficient evidence or reasoning to support its new obviousness theory based on GaN-on-SiC LEDs.” slip op. at 30

    “B. Level of Ordinary Skill in the Art Petitioner contends that a person of ordinary skill in the art in the field of the ’070 patent would have had “at least a bachelor’s degree in a field such as chemistry, physics, or chemical engineering, as well as at least two years of experience with plasma-polymerization techniques.” Pet. 14 (citing Ex. 1002 ¶¶ 26–31).

In light of the record before us, we adopt Petitioner’s proposal regarding the level of one of ordinary skill in the art. As Patent Owner points out, Dr. Gleason states that PECVD is a form of plasma polymerization, and thus the parties agree that experience with plasma-polymerization techniques would include PECVD.

    “We agree with Patent Owner. Petitioner has failed to demonstrate adequately that each and every element in claim 1, arranged as recited in the claim, is found in a single prior art reference. NetMoneyIN, 545 F.3d at 1369; Karsten Mfg. Corp. v. Cleveland Golf Co., 242 F.3d 1376, 1383 (Fed. Cir. 2001). Here, Petitioner combines several different teachings from Baalmann to support its anticipation argument. For example, Petitioner relies on the “evacuable chamber with a volume of 1 m3” from Baalmann’s Example 1, but not the power (2kW) expressly disclosed as being used with that reactor of Example 1. Ex. 1004 ¶ 47. With regard to power density, Petitioner relies on Baalmann’s general disclosure that “[t]he electrical power input per chamber volume is set between 0.5 kilowatt/m3 and 5 kilowatt/m3.” Ex. 1004 ¶ 20. As Patent Owner points out, however, that power density range is not tied to any particular reactor volume or plasma zone volume. PO Resp. 19. Baalmann also fails to expressly disclose the plasma zone volume of the reactor in Example 1. See Ex. 1004 ¶¶ 47–48. To attempt to overcome this absence of an express disclosure, Petitioner argues that, for the reactor used in Example 1, the plasma zone volume and reactor volume are the same based on the configuration of the electrodes in the reactor. Pet. 24–25. Baalmann, however, does not expressly disclose the electrode configuration of the reactor in Example 1. See Ex. 1004 ¶¶ 47–48. Instead, Petitioner relies on Baalmann’s general disclosure of an embodiment wherein one electrode is formed by the chamber wall itself. Pet. 24–25; Ex. 1004 ¶¶ 35, 61. In so doing, Petitioner ignores the fact that Baalmann also states that “[t]wo opposite rod-shaped electrodes may also be used.” Ex. 1004 ¶ 35. In view of this, we disagree with Petitioner’s conclusion that a person of ordinary skill in the art “would have understood that chamber to be configured as described throughout the rest of the specification: with the chamber wall serving as one of the electrodes.” Pet. 24. Even if we were persuaded by Petitioner’s argument, the fact remains that Petitioner’s anticipation challenge is based on the combination of different features disclosed in separate portions of Baalmann. “Such picking and choosing . . . has no place in the making of a 102, anticipation rejection.” In re Arkley, 455 F.2d 586, 587–88 (CCPA 1972) (cited with approval in Sanofi-Synthelabo v.

Pet. 38; Reply 15–16. In view of this, we are likewise not persuaded that Coulson discloses a power density of 85.1 W/m3, because Petitioner’s 9 Dr. Gleason confirmed that she did not perform any experiments to verify her opinions regarding Coulson’s plasma zone. Ex. 2017, 80:10–18. 10 As noted above, Petitioner presented its argument in the context of its proposed construction of plasma zone. Petitioner did not present an alternative argument supported by sufficient evidence addressing the volume of Coulson’s plasma zone based on Patent Owner’s proposed construction of plasma zone. Accordingly, we agree with Patent Owner’s assertion that we do not need to expressly construe the term plasma zone to resolve this issue. Sur-reply 1. argument that Coulson discloses this power density is based on its assertion that Coulson has a plasma zone volume of 470 cm3. Pet. 38. This finding is fatal to Petitioner’s obviousness challenge of claim 1 based on the combined teachings of Baalmann and Coulson because Coulson’s purported disclosure of using a power density of 85.1 W/m3 is an essential component of Petitioner’s obviousness challenge. An obviousness determination requires finding both “that a skilled artisan would have been motivated to combine the teachings of the prior art . . . and that the skilled artisan would have had a reasonable expectation of success in doing so.” Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1367-68 (Fed. Cir. 2016). In attempting to establish a person of ordinary skill in the art would have had reason to combine the teachings of Baalmann and Coulson, and would have had a reasonable expectation of success in doing so, Petitioner repeatedly refers to using Coulson’s optimized reaction conditions, including power density, in Baalmann’s larger reactor. Pet. 48 (stating that a person of ordinary skill in the art “would have been motivated to maintain the same or similar reaction conditions within a larger reaction chamber that were present in Coulson’s chamber during Coulson’s reported plasma polymerization reactions, including power density and pressure, to preserve the same effective results.”), 48–49 (“That would have included motivation to maintain Coulson’s disclosed power density when scaling up to a larger reaction volume to preserve the beneficial results Coulson reported at that optimized power density.”); Reply 23 (referring to the “straightforward, compelling obviousness case set forth in the petition” that a person of ordinary skill in the art “would have expected to succeed performing Coulson’s reactions on a larger scale in view of Baalmann”); 23 (“The petition explained why a POSA would have modified Baalmann to use Coulson’s HDFDA monomer and reaction conditions to produce coatings with a reasonable expectation of success” ), 24 (stating the Petition “explained why a POSA would have expected success using known parameters from Coulson in an established large-scale apparatus”). During the oral hearing, counsel for Petitioner confirmed its obviousness positions depend on using Coulson’s power density. Tr. 20:10–21:16. Accordingly, Petitioner’s failure to demonstrate adequately that Coulson discloses or suggests a power density of 85.1 W/m3 undermines its reason to combine and reasonable expectation of success arguments.

Patent Owner does not dispute that there is some magnetic alloy present “in the magnetic layer” of Mori. The relevant question, however, is how much and how Mori’s disclosed values were determined. Unlike the term “volume concentration,” for which the parties offered undisputed evidence regarding accepted meanings of the term in the art (i.e., packing fraction and pigment volume concentration), we have not been directed to similar evidence regarding the phrase “fill rate”/“filling rate” in Mori. Thus, although Mori states “[t]he filling rate by volume of the strongly magnetic alloy powder in the magnetic layer can be equal to or higher than 30%” (Ex. 1003 ¶ 11 (emphasis added)), Petitioner has not offered sufficient evidence demonstrating that the term “filling rate” in Mori refers to a final product-based value.

As a result, we find that Petitioner has failed to demonstrate that Aonuma and Mori disclose or suggest each limitation of claims 1–18, and, therefore, has not demonstrated by a preponderance of evidence that claims 1–18 are unpatentable as obvious over Aonuma and Mori.” slip op. at 26

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
