“Under 35 U.S.C. § 314(a), an inter partes review may not be instituted unless the information presented in the Petition and any response thereto shows “there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” Upon consideration of the Petition, Preliminary Response, and the evidence of record, we determine that the information presented in the Petition does not establish a reasonable likelihood that Petitioner would prevail in showing the unpatentability of at least one of the challenged claims. Accordingly, we do not institute inter partes review of claims 1–3, 6, 13, 14, 16–22, 26–28, and 41 of the ’138 patent based on the grounds raised in the Petition.” slip op. at 2

“Reading the ’791 provisional’s description of the hydraulic link in conjunction with Figure 2, one skilled in the art reasonably would have surmised that, in order for the trapped fluid within the cavity to act as a solid and transmit force, its thickness must remain unchanged, or, in the words of claim 1, be “substantially constant.” Indeed, according to the ’791 provisional, the fluid acts as a solid because O-ring seals and extremely small clearances between needle piston 72 and chamber cap 86 prevent the trapped fluid from flowing around the piston upon actuation of the force, which clearly supports that the thickness of the fluid must remain substantially constant. Those disclosures reasonably convey to one skilled in the art that the inventor had possession of the hydraulic link limitation of claim 1, including it having a substantially constant thickness, as of the ’791 provisional’s filing date. Likewise, we observe that claim 41 recites that the “hydraulic fluid acts as an incompressible solid so that movement caused by the actuation of said dimensionally responsive member is transmitted through said fluid layer.” Ex. 1001, 20:53–56 (emphases added). Again, the ’791 provisional discloses that the “trapped fluid acts as a solid and transmits the movement of the magnetostrictive material 40 to the needle valve 14, causing it to lift against the needle spring 16.” Id. at 12:5–13:14 (emphases added). We find, based on this description of the hydraulic link, with Figure 2, one skilled in the art reasonably would have surmised that, in order for the trapped fluid within the cavity to act as a solid and transmit force, it would act as an incompressible solid. Petitioner does not further dispute that the ’791 provisional discloses the remaining limitations of the challenged claims. As such, the evidence of record demonstrates sufficient written description support in the ’791 provisional for the challenged claims. Thus, the challenged claims are entitled to an effective filing date of October 15, 1999, which means that Gottlieb does not qualify as prior art. And because Gottlieb forms the basis of all the challenges, its exclusion is fatal to the Petition.” slip op. at 12

“For a patent to claim the benefit of the filing date of its provisional application, the provisional application must comply with the written description requirement of 35 U.S.C. § 112. Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). To show sufficient written description support, the provisional must reasonably convey to those skilled in the art that the inventor had possession of the later-claimed subject matter as of the provisional’s filing date. Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). The written description inquiry is a question of fact, and, as such, “the level of detail required to satisfy the written description requirement varies depending on the nature and scope of the claims and on the complexity and predictability of the relevant technology.” Ariad, 598 F.3d at 1351.” slip op. at 9

“The hydraulic link 22 consists of a hydraulic cavity 84 formed by hydraulic chamber 28 and hydraulic chamber cap 86. The cavity 84 is filled with viscous fluid. Within the chamber 28 is located the hydraulic piston part 72 of the needle valve 15. The chamber 28 is fitted around the hydraulic piston 72. O-ring seals 90 are located in the hydraulic chamber cap 86 and in the bottom of the hydraulic chamber 28 to prevent the fluid from leaking out of the cavity 84. The diametrical clearance between the outside diameter of the hydraulic piston 72 and the inside diameter of the hydraulic chamber 28 is extremely small (on the order of 50 to 250 microns). The exact clearance is dependent on the viscosity of the chosen fluid. The hydraulic flow in this clearance . . . is very small. The hydraulic fluid . . . acts as a solid during fast motions, because there is little flow going around the needle piston. Because the actuation occurs suddenly (on the order of 200 μs), the hydraulic fluid between the hydraulic chamber 28 and the needle valve piston 72 does not have the time to flow around the piston 72. Instead, the trapped fluid acts as a solid and transmits the movement of the magnetostrictive material 40 to the needle valve 14, causing it to lift against the needle spring 16. Id. at 12:5–13:14 (emphases added). Reading the ’791 provisional’s description of the hydraulic link in conjunction with Figure 2, one skilled in the art reasonably would have surmised that, in order for the trapped fluid within the cavity to act as a solid and transmit force, its thickness must remain unchanged, or, in the words of claim 1, be “substantially constant.” Indeed, according to the ’791 provisional, the fluid acts as a solid because O-ring seals and extremely small clearances between needle piston 72 and chamber cap 86 prevent the trapped fluid from flowing around the piston upon actuation of the force, which clearly supports that the thickness of the fluid must remain substantially constant.

“2. Summary Regarding Obviousness Challenge Because Patent Owner’s arguments and evidence persuasively rebut Petitioner’s assertion that the Ancestral Applications do not provide written description support for the challenged claims, Petitioner has not shown adequately that Babayoff ’529 is prior art to the challenged claims. Accordingly, Petitioner has not demonstrated a reasonable likelihood of prevailing on its assertion that claims 1, 4, 10, 11, 13, 18, 19, 25, and 30 would have been obvious over Babayoff ’529 and Atiya. III. CONCLUSION For the foregoing reasons, we determine that the information presented in the record does not establish there is a reasonable likelihood that Petitioner would prevail with respect to at least one challenged claim of the patent ’151 patent. Accordingly, we do not institute an inter partes review. IV. ORDER For the reasons given, it is: ORDERED that the Petition is denied; and FURTHER ORDERED that no inter partes review is instituted.” slip op. at 26

“In response, Patent Owner objects that “Petitioners’ interpretation of the claims as requiring the use of unfiltered white light to determine depth data is plainly at odds with the claims themselves.” Prelim. Resp. 4. Patent Owner argues that “[t]his interpretation leads to a contradiction between the independent and dependent claims: the same light illuminating the intraoral structure would have to be simultaneously filtered (as recited in the dependent claims) and unfiltered (as Petitioners presume to be required by the independent claims).” Id. Patent Owner also suggests the possibility that the Petition’s arguments mean “the independent claims encompass using unfiltered white light to obtain depth data.” Id. at 7. We do understand the Petition’s arguments to mean that the independent claims encompass using unfiltered white light to illuminate an intraoral structure, not that the independent claims require using white light to illuminate an intraoral structure. And we agree with that understanding of the independent claims’ scope. Consistent with Patent Owner’s explanation, if we construed the independent claims to require using unfiltered white light to illuminate an intraoral structure, that would conflict directly with the dependent claims’ express requirement to use colored filters.” slip op. at 15
