    “The parties agree that one of ordinary skill in the art “would have had at least a bachelor’s degree in a discipline related to mechanical engineering, physics, structural design, or an equivalent discipline, and at least two years of experience designing or analyzing rail cars.” Pet. 29; Prelim. Resp. 9. Patent Owner, however, disagrees that the experience should include designing or analyzing “similar vehicles.” Prelim. Resp. 9. At this stage, for the reasons below, limiting the ordinary skill in the art to “at least two years of experience designing or analyzing rail cars” does not affect our analysis of the parties’ dispute or our determination that there is a reasonable likelihood that Petitioner would prevail with respect to at least one of the challenged claims. Thus, based on the preliminary record, we adopt Petitioner’s proposed level of ordinary skill to determine whether review should be instituted. Patent Owner also argues that Petitioner’s declarant does not have “actual industry experience with railcar structures” and, thus, “makes the wrong conclusions and conflates various concepts that a [person of ordinary skill in the art] with practical industry experience and knowledge of rail cars would not.” Prelim.

    “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

    “anticipated by Rao. Pet. 1, 30–31, 33–42. We have reviewed Petitioner’s arguments for each of those dependent claims. See Pet. 30–31, 33–42. For each of those dependent claims, the Petition appears to only argue a theory of obvious. That is, the Petition never states that the additional limitation is disclosed by Rao. See id. For example, claim 26 depends from claim 1 and further recites “wherein the policy is based on a background service class.” Ex. 1001, 112:49–52. We reproduce Petitioner’s arguments directed to claim 26 below: Rao’s policies 520 may “define prioritization” for network packets “based on whether an application is running in the foreground or the background.” [Ex. 1002] ¶ 182; id. ¶¶ 38–43, 180, 182, 188–89, 193, Figs. 5A, 5B. Each packet “may be placed and arranged in a priority order respective to all other . . . packets to provide a packet by packet prioritization across all applications 338a-338n and . . . network packets.” Id. ¶ 191. It would have been obvious to determine and apply a policy assigning a specific priority to packets associated with background applications, supra [1e]-[1f], and Rao thus discloses or renders obvious assigning a priority to network communications based on whether they are characterized as background services (class of services associated with application(s) running in the background of client 105), EX-1015 ¶¶195-96; supra [1e], [1f]. Pet. 33–34. Although the Petition sets forth why the claim limitation would have been obvious, there is no discussion as to how the additional limitation of claim 26—policy based on background class—is disclosed in Rao. See id. Similar arguments are presented for the other claims. See Pet. 30–31, 35–42. Because the Petition does not sufficiently show how the additional limitations recited in claims 20, 26, 58, 64, 165, and 169 were disclosed by Rao, Petitioner has not shown by a preponderance of the evidence that claims 20, 26, 58, 64, 165, and 169 were anticipated by Rao.” slip op. at 28

    “Patent Owner’s argument are persuasive. We agree with Patent Owner that a plain reading of the wherein clause requires the treating to begin at the introitus and extend at least the first centimeter into the vagina and up to 3.5 cm in from the introitus. This construction is consistent with the ’511 patent’s Specification, which states: In typical embodiments, the length of the energy delivery element is about 1 to about 3 cm in length, in other embodiments it may be as long as about 4 cm. This is a length well adapted to treating the lower aspects of the vagina, wherein treatment by the method comprises contacting the vaginal epithelium in a region that extends from the introitus inward to a position about 3 to 4 cm inward from the introitus. In some embodiments of the invention, the method can b[e] practiced with a single row of parallel contract sites immediately inside the introitus. In other embodiments, the method may include deeper rows, or rows that overlap an initial row, while keeping the contact sites within the lower portion of the vagina. Ex. 1001, 3:28–40 (emphasis added); see also id. at 14:47–57. The ’511 patent Specification also states: “the portion of the vagina to be treated is a region between the introitus and a position located no further than about 3 to about 4 cm inward from the introitus.” Id. at 11:48–51 (emphasis added). Given the plain language of claim 1, consistent with the ’511 patent’s Specification, we construe “heating a portion of the vagina extending from the introitus inwardly to a location from 1 cm to 3.5 cm in from the introitus” to require heating a portion of the vagina beginning at the introitus and extending at least the first centimeter into the vagina and up to 3.5 cm in from the introitus.” slip op. at 12
