      “The invention, a reciprocating massage device, is in a predictable field, namely the electro-mechanical arts. Also, there is no evidence that the recited quick-connect system is complex, even considering Patent Owner’s alleged understanding of it. Rather, Dr. Pratt testifies that many different types of connectors, whether they require alignment or not, were known. Ex. 1002 ¶¶ 54–58. Given the predictability of the electro-mechanical arts and lack of complexity of the recited quick-connect system, a low level of detail is required to satisfy the written description requirement. See RAI Strategic Holdings, Inc. v. Philip Morris Prods. S.A., 92 F.4th 1085, 1090 (Fed.

Smith & Nephew, Inc., 884 F.3d 1357, 1361 (Fed. Cir. 2018)). In view of the low level of detail required to satisfy the written description requirement, Petitioner has not persuaded us that the Specification’s example of a quick-connect system configured to secure the massaging head as the piston reciprocates fails to provide sufficient written description support for the “quick-connect system” recited in independent claims 1 and 18.” slip op. at 14

      “Contrary to Petitioner’s assertion, the Specification provides guidance as to what amount of deviation from a perfect cylinder is still “substantially cylindrical.” The Specification describes: Quick-connect system 600 includes a piston 602 that has a hollow-end bore 608 for receiving the shaft 621 of a massaging head 620. Located within the bore 608 of piston 602 is a cylindrical seat 604. Cylindrical seat 604 retains a magnet 606. Magnet 606 is illustrated with its north pole located flush with the seat and facing toward the opening in bore 608. Massaging head 620 includes a shaft 621 having a cylindrical pocket 622 at the distal end. Located within the cylindrical pocket 622 is a magnet 624. Magnet 624 is positioned so that its south pole is located at the distal end of shaft 621. Accordingly, when the shaft 621 of massaging head 620 is slid into opening in bore 608, the magnets 606 and 624 are attracted to one another and magnetically hold massaging head 620 firmly in place. Ex. 1001, 6:57–7:3. In view of the description of quick-connect system 600, the Specification sets forth a standard for ascertaining whether the bore and the seat located within the bore are “substantially cylindrical.” To wit, the bore and the seat within the bore are “substantially cylindrical” when the massaging head and magnet are respectively received therein so that the magnet in the seat and the magnet in the pocket of the massaging head can magnetically hold the massaging head firmly in place. Furthermore, Dr. Pratt testifies that “[m]agnetic connectors comprise a magnet on at least one of the two objects to be joined. These types of connectors are ubiquitous even today for driving threaded fasteners.” Ex. 1002 ¶ 56. Dr. Pratt also testifies that a POSITA would understand how to take into account certain variances, like runout. Ex. 2033, 25:3–17. Dr. Pratt’s testimony shows that magnetic connectors are well known and that a POSITA would be able to determine whether the bore and the seat within the bore were “substantially cylindrical” for a secure connection of the massaging head. In view of the foregoing, Petitioner has not persuaded us that the claim term “substantially cylindrical” recited in claims 13–16 fails to inform, with reasonable certainty, the shapes of the bore and the structure within the bore. Petitioner has not proven, by a preponderance of the evidence, that any of claims 13–16 are unpatentable under 35 U.S.C. § 112(b) as indefinite.” slip op. at 19

      “The invention, a reciprocating massage device, is in a predictable field, namely the electro-mechanical arts. Also, there is no evidence that the recited quick release connector is complex, even considering Patent Owner’s alleged understanding of it. Rather, Dr. Pratt testifies that a POSITA would be able to recognize a quick release connector for a particular application. According to Dr. Pratt, A person of ordinary skill in the art would consider a number of factors, depending on the context and specific application of the connector, to determine whether a connector provides a “quick release.” Such factors could include whether the connector is designed to manually and easily connect and disconnect two objects, and whether tools are necessary to do so. Other factors to be considered may be based on the specific application or operating environment. Ex. 1002 ¶ 58. Given the predictability of the electro-mechanical arts and lack of complexity of the recited quick release connector, a low level of detail is required to satisfy the written description requirement. See RAI Strategic Holdings, Inc. v. Philip Morris Prods. S.A., 92 F.4th 1085, 1090 (Fed.

In view of the low level of detail required to satisfy the written description requirement, Petitioner has not persuaded us that the Specification’s example of a quick release connector configured to secure the massaging head as the piston reciprocates fails to provide sufficient written description support for the “quick release connector . . . configured to secure a first massaging head while the piston reciprocates a predetermined stroke length at the first speed” recited in claim element 34[e]. 4. Conclusion for Written Description For the reasons set forth above in sections II.C.1–3, Petitioner has not persuaded us that any aspect of claim element 34[e] lacks written description support. Petitioner has not proven, by a preponderance of the evidence, that independent claim 34, as well as any of claims 35–38, 40, 41, 43–46, and 58–60 depending therefrom, are unpatentable under 35 U.S.C. § 112(a).” slip op. at 18

      “Contrary to Petitioner’s assertion, the Specification provides guidance as to what amount of deviation from a perfect cylinder is still “substantially cylindrical.” The Specification describes that quick-connect system 600 includes two magnets with opposite poles facing each other: magnet 606 in the distal end of piston 602 and magnet 624 located in cylindrical pocket 622 of massaging head 620. Ex. 1001, 6:57–67, Figs. 6, 6A. The Specification further describes that “when the shaft 621 of massaging head 620 is slid into opening in bore 608, the magnets 606 and 624 are attracted to one another and magnetically hold massaging head 620 firmly in place.” Id. at 6:67–7:3. In view of the description of quick-connect system 600, the Specification sets forth a standard for ascertaining whether the pocket is “substantially cylindrical.” To wit, the pocket is “substantially cylindrical” when the pocket receives a magnet therein so that the magnets can magnetically hold the massaging head firmly in place. Furthermore, Dr. Pratt testifies that “[m]agnetic connectors comprise a magnet on at least one of the two objects to be joined. These types of connectors are ubiquitous even today for driving threaded fasteners.” Ex. 1002 ¶ 55. Dr. Pratt also testifies that a POSITA would understand how to take into account certain variances, like runout. Ex. 2033, 25:3–17.

In view of the foregoing, Petitioner has not persuaded us that the claim term “substantially cylindrical” recited in independent claim 34 fails to inform, with reasonable certainty, the shape of the pocket. Petitioner has not proven, by a preponderance of the evidence, that independent claim 34, as well as claims 35–38, 40, 41, 43–46, and 58–60 depending therefrom, are unpatentable under 35 U.S.C. § 112(b) as indefinite.” slip op. at 21

      “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). Petitioner does not refute this proposed construction and, during the oral argument, Petitioner confirmed it agrees with the proposed construction. Tr. 8:16–9:12. We so no reason to depart from the parties agreed-upon construction of limitations [1.d] and [13.c].

      “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. Ex. 2011 ¶ 54; see also Ex. 1005, 65 (“The surface properties of that confining layer are not well controlled.”).” slip op. at 19

      “In an inter partes review, the burden of persuasion is on the petitioner to prove ‘unpatentability by a preponderance of the evidence,’ . . . and that burden never shifts to the patentee.” Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015) (quoting 35 U.S.C. § 316(e)). Here, Petitioner asserts that (1) the combined teachings of the Ungerank Patent and Scholz disclose or suggest all of the limitations of claims 1–5, 7, 9, and 11–23 of the ’380 patent, and (2) the Ungerank Patent qualifies as prior art because the portions cited in the Corrected Petition and the Baker Declaration were published in the Ungerank Application.7 slip op. at 16

      “Petitioner ultimately has the burden of persuasion, based on all the evidence, on both these assertions. See Dynamic Drinkware, 800 F.3d at 1378. After reviewing the parties’ arguments and the evidence of record, we are not persuaded that Petitioner establishes, by a preponderance of the evidence, that the portions of the Ungerank Patent relied on in the Corrected Petition and the Baker Declaration qualify as prior art. There is nothing in the Initial Petition or the exhibits filed in support thereof that indicates Petitioner’s intention to rely on the Ungerank Application as prior art in this proceeding. The Initial Petition defines “Ungerank” as the Ungerank Patent, and all citations to “Ungerank” in support of Petitioner’s allegations are to the Ungerank Patent. Initial Pet. 3, 12–14, 17–42. The Initial Petition does not refer to the Ungerank Application, and the Ungerank Application was not submitted as an exhibit with the Initial Petition. Id. at iii–v (Exhibit List). And Petitioner’s expert declarant, Dr. Baker, did not consider the Ungerank Application when formulating his opinions in support of the Initial Petition.

Although the Corrected Petition redefines “Ungerank” as the Ungerank Application, the Corrected Petition retains its citations to the Ungerank Patent.8 Corrected Pet. 3, 12–15, 18–43. In that regard, Petitioner generally asserts that the Ungerank Application’s “specification and figures 8 At the hearing, Petitioner’s counsel stated that they left the citations to the Ungerank Patent in the Corrected Petition because they “didn’t want to make tons and tons of changes,” and the Ungerank Patent citations “are much more specific.” Tr. 12:10–13; see also Pet.

      “Our rules provide that a petitioner must include “[a] full statement of the reasons for the relief requested, including a detailed explanation of the significance of the evidence including material facts, and the governing laws, rules, and precedent.” 37 C.F.R. § 42.22(a). Our rules also state that “[a] reply may only respond to arguments raised in the corresponding . . . patent owner response.” Id. § 42.23(b). “‘Respond,’ in the context of 37 C.F.R. § 42.23(b), does not mean proceed in a new direction with a new approach as compared to the positions taken in a prior filing.” CTPG 74. Our Trial Practice Guide explains 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.” Id. at 73; see also id. at 74 (“Examples of indications that a new issue has been raised in a reply include new evidence necessary to make out a prima facie case for the patentability or unpatentability of an original or proposed substitute claim, such as newly raised rationale to combine the prior art references that was not expressed in the petition.”). In the Reply, Petitioner argues that “POSITAs ‘might have already figured out’” that, in Comparative Example 1, the surface area of the membrane in stage 2 was larger than that of the membrane is stage 1, and Scholz’s Figure 7 systems with larger stage 2 membrane areas than stage 1 were “consistent with POSITAs’ likely intuition about [Comparative Example 1’s] stage 2 and stage 1 areas.” Pet. Reply 19. As Petitioner concedes, this “an additional reason POSITAs would have found it appropriate to look to Scholz’s Figure 7 to better understand [Comparative Example 1’s] relative surface areas.” Id. (citing Ex. 1041 ¶¶ 31–32) (emphasis added). The case presented in the Corrected Petition is that a POSITA would have looked to Scholz because Comparative Example 1 does not provide details on the area of the membranes or their ratios. Corrected Pet. 18–19. Petitioner’s admitted “additional reason” to combine the Ungerank Patent and Scholz in the Reply is a newly raised rationale to combine the prior art references necessary to make out a prima facie case of unpatentability.

There is no dispute as to limitations [1.C] and[13.C] requiring a controller connected to the chambers so that each chamber is able to actuate the release of water from the chamber independently of the release of water from the other chambers. For a disclosure of the recited controller, Petitioner relies solely on Raike’s embodiment employing a third mode of operation. Tr. 18:21. Raike discloses the third mode of operation in a single sentence: “all of the caissons 31–34 can be actuated at different times in a predetermined or random sequence.” Ex. 1004, 6:62–64. This sentence does not expressly disclose actuating each caisson independently of the other caissons and is ambiguous as to whether the caissons are actuated in pairs in a predetermined or random sequence or one at a time in a predetermined or random sequence. Petitioner argues a POSITA would understand Raike’s disclosure of the third embodiment to be the latter, namely actuating the caissons in any sequence, including the independent actuation of each caisson one at a time in sequential order. Petitioner’s argument is based on Dr. Stevick’s explanation of how Raike’s pneumatic system could actuate the caissons one at a time in sequential order. Dr. Stevick’s explanation, however, misrepresents Raike’s pneumatic system. Dr. Stevick’s explanation entails pendulum duct sections 63 being in a neutral position in which pendulum duct sections 63 are situated in a vertical orientation halfway along their arcuate path of travel. Ex. 1016 ¶¶ 52–43; Ex. 2010, 23:4–17. Raike is silent regarding any neutral position. Moreover, Raike does not disclose situating pendulum duct sections 63 in a vertical orientation halfway along their arcuate path of travel but instead discloses swinging pendulum duct sections 63 between two extreme positions of their arcuate paths.

      “For purposes of the present invention, the term “removably clumpable” refers to a litter that, when exposed to a wetting agent forms one or more clumps having a firmness of sufficient structural integrity and hardness to withstand mechanical separation from unwetted litter for disposal. A litter material having a clump strength of ≤1.33 using the Standard Drop Method Test (described below) 30 seconds, 1 hour, 12 hours, 24 hours, 36 hours or 72 hours after the clump is formed by exposure to a liquid is removably clumpable. A litter that is removably clumpable, i.e., has a clump strength of ≤ 1.33 using the Standard Drop Method Test, has a clump strength that is substantially the same as a litter comprised of only the sodium bentonite of the litter.

See PO Resp. 6. Petitioner disagrees, but attempted to follow the method set forth in the ’393 patent in its argument and evidence filed in connection with its Reply. See Tr. 8:15– 9:8. Petitioner does not meet its burden to show the combination teaches a limitation by simply stating that a PHOSITA would recognize that the limitation would be met, without explaining how or providing the data necessary to test the assertion. Because neither the Petition nor the declaration of Mr. Raymond identifies any particle sizes for the cellulose-containing filler material it relies on or any method of calculating the total surface area of the litter formulation, without that information, Petitioner fails to show that the proposed combination would have inherently, or necessarily, met the 47% of the total external surface area limitation.” slip op. at 20

      “Even if we agree with Patent Owner that elongating projections 10 would have the undesirable side effect of decreasing the surface temperature, the drawback of decreased surface temperature does not necessarily disqualify the benefit of better bristle retention as a reason to elongate projections 10, as Petitioner proposes. See Winner Int’l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 n.8 (Fed. Cir. 2000) (“The fact that [a] motivating benefit comes at the expense of another benefit . . . should not nullify its use as a basis to modify the disclosure of one reference with the teachings of another. Instead, the benefits, both lost and gained, should be weighed against one another.”). We agree with Petitioner that bristle securement is important to enable the bristles to reliably space the heated surface from a user’s skin. Moreover, given Patent Owner’s reliance on Mr. Prehodka’s testimony that doubling the length of projections 10 would provide only an insubstantial increase in the overall surface area (Sur-reply 12), there is no dispute that lengthening projections 10 would result in an insubstantial decrease in temperature, which is inversely proportional to surface area (PO Resp. 23). As lengthening projections 10 would increase bristle retention, which is important to enable the bristles to provide a space between the heated surface and a user’s skin, and result in only an insubstantial decrease in temperature, we are persuaded a person of ordinary skill in the art would have prioritized the benefit of better bristle retention over the drawback of decreased surface temperature. Furthermore, we disagree with Patent Owner that Lim teaches away from lengthening heating elements that are monolithic with a heating plate. Lim teaches a concern about heating elements breaking with respect to a prior art brush having heating elements embedded in the surface of the roll. Ex. 1005 ¶ 29.

We further disagree with Patent Owner that Ida teaches away from lengthening heating elements that are monolithic with a heating plate. Although Ida may raise a concern about cleaning heating elements that are monolithic with a heating plate (Ex. 1018 ¶¶ 11–13), such a concern about cleaning the heating elements arises from the elements being monolithic with the heating plate, not the length of the heating elements. Thus, Ida’s teaching that cleaning heating elements monolithic with a heating plate is problematic does not discourage lengthening such heating elements. Moreover, Gress’s preferred embodiment lacking a monolithic construction does not teach away from lengthening heating elements that are monolithic with a heating plate. See In re Fulton, 391 F.3d 1195, 1200 (Fed. Cir. 2004) (“[O]ur case law does not require that a particular combination must be the preferred, or the most desirable, combination described in the prior art in order to provide motivation for the current invention.”); see also id. at 1201 (holding “the prior art’s mere disclosure of more than one alternative does not constitute a teaching away from any of these alternatives because such disclosure does not criticize, discredit, or otherwise discourage the solution claimed”). Although Gress’s preferred embodiment does not include a monolithic construction, Gress nonetheless discloses an embodiment with projections 10 being monolithic with cover 8. Ex. 1011, 2:27–32, Figs. 1–3.” slip op. at 27
