RulingsFinal written decision- Skill levelSkill level petitioner adoptedDecided for petitioner
“Patent Owner proposes that a person of ordinary skill in the art “would have a Bachelor of Science degree in Electrical Engineering, Computer Engineering, Computer Science, Human Computer Interaction, or a related technical field, with at least one year of experience working in the field of user interfaces and/or content management.” PO Resp. 11 (citing Ex. 2040 ¶ 53). The Decision on Institution adopted Petitioner’s proposed level of ordinary skill in the art. Inst. Dec. 10. We find Patent Owner’s stated level to be less precise than that proposed by Petitioner in that the modifier “at least” used by Patent owner imposes no upper bound on the amount of experience possessed by one of ordinary skill in the art. Also, Patent Owner states: “The difference between the Board’s definition and Patent Owner’s (EX2040. ¶53) does not change the arguments set forth herein.” PO Resp. 11. Thus, we continue to adopt Petitioner’s stated level of ordinary skill in the art.4 4 All of our findings and conclusions would still be the same, however, had we applied Patent Owner’s articulation of the level of ordinary skill in the art.” slip op. at 8

“In its Reply, Petitioner does not assert that the district court’s construction is incorrect. We agree with Patent Owner that the district court’s construction is better than Petitioner’s proposed construction, because for reasons indicated by Patent Owner, which are not disputed by Petitioner, settings in the computer, e.g., dedicated folders for each user are the user profiles, rather than simply data alone of any kind. Further, when asked about the appropriateness of the district court’s construction, counsel for Petitioner expressed that Petitioner has no objection to the Board’s adopting the district court’s construction for “user profile”: JUDGE LEE: So, you’d be fine with just going with the District Court’s construction? MR. HEINTZ: Yes, Your Honor. Tr. 15:22–24. For the foregoing reasons, we adopt the district court’s construction for “user profile,” i.e., “a collection of settings and information associated with a user.”” slip op. at 13

“PO Resp. 30–31 (Figure 26 omitted). In its Reply, Petitioner still does not provide an articulated reason for placing user profile selection buttons, labeled with user names, within Horn’s panes 2601 or 2602. Reply 12–14. Although Horn does describe personalized profile, Petitioner points to no disclosure of Horn as to how a user would have selected his or her own profile from among a plurality of user profiles. Petitioner presents no reason for placing these user profile selection buttons, labeled with user names, gleaned from or suggested by Baumgartner, within either pane 2601 or pane 2602 in Horn’s workspace view. Further, pane 2602 contains “a list of all collections defined by MFS and the user,” and pane 2601 lists the source examined by the user to create his or her collections. Ex. 1005, 19:41–46. That disclosure suggests the contents of panes 2601 and 2602 are tied to one particular user. No rational basis is articulated by Petitioner to place user profile selection buttons within these panes which appear to be in the profile space of one user. For the foregoing reasons, Petitioner has not adequately accounted for limitation 16[b].” slip op. at 22
- Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner
“The test for sufficiency of a written description under 35 U.S.C. § 112 is whether the earlier application’s disclosure “reasonably conveys to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date.” Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). The specification must “clearly allow persons of ordinary skill in the art to recognize that [the inventor] invented what is claimed.” Id. The Court of Appeals for the Federal Circuit has explained: One shows that one is “in possession” of the invention by describing the invention, with all its claimed limitations, not that which makes it obvious. Id. (“[T]he applicant must also convey to those skilled in the art that, as of the filing date sought, he or she was in possession of the invention. The invention is, for purposes of the ‘written description’ inquiry, whatever is now claimed.”) (emphasis in original). One does that by such descriptive means as words, structures, figures, diagrams, formulas, etc., that fully set forth the claimed invention. Although the exact terms need not be used in haec verba, see Eiselstein v. Frank, 52 F.3d 1035, 1038, 34 USPQ2d 1467, 1470 (Fed.Cir.1995) (“[T]he prior application need not describe the claimed subject matter in exactly the same terms as used in the claims. . . .”), the specification must contain an equivalent description of the claimed subject matter.

“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).

- 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

“each antenna” and “Agee’s Butler matrix measures a different signal strength for each of the 32 OFDM tones (channels) on each antenna” (Pet. 62), Agee does not describe that its Butler Forming Mode circuitry determines (or measures) signal strength. Rather, Petitioner relies on unsupported testimony from Dr. Mahon. Pet. 61 (citing Ex. 1003 ¶¶ 513– 536). Although Dr. Mahon affirmatively states that Agee discloses measuring the “signal strength” for limitations [1.4] and [1.5], he only quotes Agee’s column 45, lines 4–28 to conclude that “such measurements are detecting and processing the signal strength in the passages regarding the OFDM vector receiver receiving and detecting data induced on each antenna.” Ex. 1003 ¶ 524. However, the testimony provides no further explanation as to why this is the case other than quoting the paragraph.

Consequently, assessing the probative value of the testimony, we find that the bare, unintelligible statements regarding Agee and how it allegedly teaches “signal strength” are entitled to little weight.14 14 We recognize that at the Decision on Institution stage, the panel credited Dr. Mahon’s testimony with respect to how the Butler matrix detects different phased signals at the antenna for limitations [1.3]−[1.5].

See Netflix, 84 F.4th at 1377 (stating that “the Board should . . . not have to decode a petition to locate additional arguments beyond the ones clearly made”). Petitioner also does not provide sufficient support for these contentions from Butler. In sum, Petitioner relies on Dr. Mahon’s testimony for the contentions in limitations [1.4] and [1.5], at least with regard to determining “signal strength” as the recited determining first and second “signal information.” As explained in our Consolidated Trial Practice Guide15 (Nov. 2019) at 36: Expert testimony, however, cannot take the place of a disclosure in a prior art reference, when that disclosure is required as part of the unpatentability analysis . . . Similarly, in an obviousness analysis, conclusory assertions from a third party about general knowledge in the art cannot, without supporting evidence of record, supply a limitation that is not evidently and indisputably within the common knowledge of those skilled in the art. K/S Himpp v. Hear-Wear Techs., LLC, 751 F.3d 1362, 1365 (Fed. Cir. 2014). Furthermore, because an inter partes review may only be requested “on the basis of prior art consisting of patents or printed publications,” 35 the standard changes.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1377 (Fed.

The Board is free to change its view of the merits after further development of the record, and should do so if convinced its initial inclinations were wrong.” TriVascular, 812 F.3d at 1068. 15 Available at https://www.uspto.gov/sites/default/files/documents/ tpgnov.pdf U.S.C. § 311(b), expert testimony cannot take the place of disclosure from patents or printed publications.

“Both parties maintain that no claim term needs to be construed. Pet. 4 (citing Ex. 1003 ¶ 40); PO Resp. 20. Patent Owner, however, provides an express construction for limitation [1.d] of independent claim 1 and the similar limitation of independent claim 13, namely limitation [13.c]. PO Resp. 20 (citing Ex. 2011 ¶ 25). To resolve the controversy before us, we determine that these limitations require express construction. 1. “the glass element is configured to propagate and modify a stress wave to the coating/substrate interface to generate a tensile stress between the substrate and the coating” (limitation [1.d]) and “propagating and modifying a stress wave through the glass element to the coating/substrate interface to generate a tensile force between the substrate and the coating” (limitation [13.c]) Patent Owner argues these limitations mean “changing the profile of the laser generated compressive wave and propagating the wave profile as modified to the free surface of the coating, which upon reflection from the free surface as a tension wave generates a tensile stress at the coating/substrate interface.” PO Resp. 20 (citing Ex. 2011 ¶ 25).

“a shock in the compression wave in the fused silica substrate. Even if we were to agree with Petitioner that Wang-Dissertation’s fused silica substrate modifies the compression waveform, we would not be persuaded that the fused silica substrate propagates the modified wave to the free surface of the coating, which upon reflection from the free surface as a tension wave generates a tensile stress at the coating/substrate interface, as limitation [1.d] requires. In view of the presence of tension-wave-1 in Wang-Dissertation’s experiments, we find Petitioner has not demonstrated persuasively that the fused silica substrate propagates a modified stress wave to the free surface of the coating to generate a tensile stress at the coating/substrate interface. Also, we find credible Dr. Gupta’s unrebutted testimony that any modified compression wave would attenuate in the substrate and not propagate to the free surface coating or generate a tensile stress at the coating/substrate interface. Ex. 2011 ¶¶ 93–98. Petitioner does not dispute that the experiments in Wang-Dissertation include tension-wave-1. See Ex. 1005, 65 (“The experimental picture is complicated somewhat by the presence of a tensile wave, reflected from the back of the confining layer.”). Nor does Petitioner dispute that Wang-Dissertation discloses that the tension-wave-1 propagates faster than the compression-wave-1 and eventually overtakes compression-wave-1. See id. at 65–66 (“Being tensile, it propagates faster that the peak compressive stress, and faster than the low stress tail of the main pulse. It eventually overtakes the compressive pulse and linear dissipative mechanisms govern the final thickness of the shock.”). Rather, Petitioner relies on Dr. Wang’s testimony regarding the timing of the waves through the sample and argues that tension-wave-1 does not overtake compression-wave-1 in the fused silica substrate. Pet. Reply 17 (citing Ex. 1038 ¶ 5). Dr. Wang testifies that the peak stress from tension-wave-1 is about 2 ns behind the peak of compression-wave-1 and will not reach the interface before the reflected tensile peak of compression-wave-1 reaches the interface in 0.3 ns. Ex. 1038 ¶ 5. However, as Dr. Gupta persuasively explains, the delay between tension-wave-1 and compression-wave-1 depends on the properties of the confining layer, and Wang-Dissertation acknowledges that these properties are not well controlled.

“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

“(opining that “Patent Owner’s construction of ‘having an axis no located in a geometric center’ is too narrow”). Mr. Nranian’s Declaration testimony in this respect is not persuasive for several reasons. First, it is internally inconsistent. Compare Ex. 1016 ¶ 3 (criticizing the “axis” language in Patent Owner’s definition), with id. ¶¶ 9, 11 (relying on that very language to support an argument). Also, Mr. Nranian’s proposed definition of “eccentric” to merely mean “not located at the center” begs the question of what, precisely, is “the center”? Mr. Nranian does not persuasively explain how far a person of ordinary skill in the art would understand she could travel from the exact center point of an object and still be in “the center” of that object. See Tr. 10:13–19 (Judge McGee asking whether the center is “a miniscule point in the middle of [the] disc”); see also id. at 10:25–12:26 (Judge Weatherly highlighting the significant ambiguity in referring to something as in “the center”). Also, Mr. Nranian’s opinion is inconsistent with how the ʼ203 patent compares something that is “central,” i.e., “at the center,” and something that is “eccentrically” located. Ex. 1001, 7:13–14 (describing pipe nozzle 15 as “central”); id. at 8:53–56 (describing a “through hole” as “located in the center of the front panel 22” depicted in Figures 7 and 8); id. at 10:23–31 (describing return 12 as “in the center” and outlet 13 as “eccentrically thereto” in Figure 17). Patent Owner’s colorized and annotated Figure 7 is reproduced below: Patent Owner’s colorized and annotated version of Figure 7 of the ʼ203 patent illustrates “central pipe nozzle 15” in yellow passing through the “through hole” located in “the center” of front panel 22. PO Resp. 20. Significantly, pipe nozzle 15 and the through hole in panel 22 are both described as “central” and in “the center” but must have different diameters; otherwise, “central pipe nozzle 15” would not be capable of traveling through “through hole 22.” Ex. 1001, Fig. 7. Thus, the ʼ203 patent intrinsically bases whether an element is “central” or “in the center” on whether its axis is located at the geometric center. This is also illustrated in Figure 17 of the ʼ203 patent, reproduced below: Figure 17 of the ʼ203 patent illustrates filter housing 10 with return 12 “in the center . . . and, eccentrically thereto, the outlet 13 with the seat 14 for the blocking element 24.” Ex. 1001, 10:23–30. Finally, Mr. Nranian’s narrow interpretation of “eccentric”––which excludes the “having the axis or support so located” in the geometric center language––is at odds with the arguments it was proffered to support. Cf. Pet. Reply 9 (arguing that certain elements are eccentric because they “do not have an axis located at the geometric center”); id. at 10 (arguing the eccentricity of an element that does “not have an axis in the center” which has “an off-center axis”).” slip op. at 29
