    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

      “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

      “1. “closure retention mechanism” Trove proposes that “closure retention mechanism” should be construed as a means-plus-function term under 35 U.S.C. § 112(f). See Pet. 18–19; Pet. Reply 1. CamelBak agrees. See PO Resp. 8. Indeed, subsequent to our institution decision, the district court in the parallel action held that the “closure retention mechanism” is a means-plus-function term governed by 35 U.S.C. § 112(f). See Ex. 2010, at 5–6. We see no reason to depart from that holding and adopt the district court’s reasoning in that regard as our own. See id. at 6–8.” slip op. at 7

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

      “We agree with CamelBak that the plain language of the claim imposes a temporal condition on when the closure is received by the closure retention mechanism, namely, only after it is removed from the drink spout. In other words, the closure cannot be in engagement with, i.e., “received by,” the closure retention mechanism while it remains on the drink spout. This interpretation is consistent with the specification, which repeatedly states that spaced-apart tabs 56 “engage” the closure when it is removed from the spout and moved to the stowed position. Ex. 1001, 8:58–60 (“tabs 56 . . . are configured to selectively engage and retain, or otherwise grip, the closure in the stowed position”); 9:32–39 (“when the closure is positioned between and/or otherwise in engagement with the tabs, the tabs engage the closure across the maximum width, such as with the tabs resiliently deflecting, bending, or compressing to accommodate the greater width of the closure”); 11:36–39 (“the closure retention mechanism 54 may be configured to engage . . . the closure to operatively retain the closure in its stowed configuration.”); 13:26–31 (“When the closure is operatively positioned within the closed perimeter of the handle into its stowed position . . . such closure is compressed slightly.”) (emphases added). Moreover, the specification describes this engagement as occurring by means of a “friction-fit” or “snap-fit” arrangement (id. at 8:50–52, 14:33– 36), which confirms that the closure is not permanently engaged with the tabs, but rather moved into engagement with the tabs, i.e., “received by the closure retention mechanism” per the plain language of the claim. Thus, the intrinsic evidence—the claim language and the specification—supports a construction that imposes a temporal condition on the recited function of the claimed “closure retention mechanism” such that it receives the closure only after the closure has been removed from the drink spout, meaning the closure is not engaged with the closure retention mechanism before it is selectively removed from the drink spout.” slip op. at 13

      “3. “retain the closure in a stowed position” CamelBak contends that this limitation should be construed to mean “to hold or keep the closure in a position removed from the drink spout.” PO Resp. 13–14; PO Sur-Reply 4. Although Trove contends that CamelBak’s construction “impermissibly rewrites” the claim language, Trove nonetheless “does not disagree that it encompasses ‘hold or keep the Indeed, the claim language itself already contemplates just such a construction by expressly reciting that the closure retention mechanism “selectively retain[s] the closure in a stowed position relative to the handle when the closure is selectively removed from the drink spout.” Ex. 1001, 18:63–66 (emphasis added). As such, we determine that further construction of this limitation is not necessary to resolve the present dispute.” slip op. at 14

Indeed, the court in the Apple Litigation has concluded that the control component requirement is subject to 35 U.S.C. § 112(f), and has construed that requirement accordingly: Function: receiving control signals input to the oscillating resonant module; receiving outputs from the one or more sensors; controlling oscillation of the mass to produce a vibration response according to the received control signals by generating, using one or more of the received sensor outputs, control outputs to an actuator that drives the mass to oscillate. Structure: a microcontroller, a processor, a microprocessor, or a CPU that performs the algorithm shown in Figure 45 or the algorithm described in the corresponding text. See, e.g., 31:19–32:13, and equivalents thereof. Ex. 2001, 10; Ex. 2002, 40.

    • Obviousness (§103) › Analogous artAnalogous artDecided for petitioner

      “(1) Analogous Art Our reviewing court has stated that “[t]wo separate tests define the scope of analogous prior art: (1) whether the art is from the same field of endeavor, regardless of the problem addressed and, (2) if the reference is not within the field of the inventor's endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved.” In re Bigio, 381 F.3d 1320, 1325 (Fed. Cir. 2004) (citations and internal quotes omitted). While these two criteria are helpful in many instances, we must not lose sight of the key question at hand: what is “prior art” as that term is used in 35 U.S.C. § 103(a)? References that are “too remote to be treated as ‘prior art’” are excluded from the obviousness analysis. In re Sovish, 769 F.2d 738, 741, 226 (Fed. Cir. 1985). The non-analogous art test provides helpful insight on the underlying question of what is “prior art” within the meaning of the statute; we should not, however, be blind to the reality of the circumstances of the case before us. In re Wood, 599 F.2d 1032, 1036 (CCPA (1979). Nor should we adhere to rigid and mandatory formulas that overly limit the inquiry. KSR Int’l Co., 550 U.S. at 419.” slip op. at 22

      “We have also considered the expert testimony. Patent Owner’s expert Mr. Occhiogrosso opines that synchronizing context stacks must include duplicating the order of entries in the stacks.

See id. ¶¶ 39, 70, 72 (citing Ex. 1001, 20:10–12, 20:19–22). Thus, Mr. Occhiogrosso’s extrinsic testimony on this point is overly conclusory, and we accordingly give it little weight here. Moreover, although extrinsic evidence such as expert witness testimony “can shed useful light on the relevant art,” it is “less significant than the intrinsic record in determining ‘the legally operative meaning of claim language.’” Phillips, 415 F.3d at 1317 (citations omitted); see also id. at 1318 (“We have viewed extrinsic evidence in general as less reliable than the patent . . . in determining how to read claim terms.”); Seabed Geosolutions (US) Inc. v.

Nonetheless, in order to provide a complete record for federal court review if sought by Petitioner, we will go on to consider the substantive merit of the arguments in the Petitioner Reply.

For multiple reasons, this testimony fails to support Petitioner’s suggestion that using SAP ammunition in Peev’s airsoft gun was among a finite number of identified, predictable solutions.
