“We disagree. Positioning module 6 to face a “predetermined direction” is a form of preventing movement that falls within the scope of limitation 1b. Moreover, Yamaguchi-727 uses a method for preventing movement of its module 6 in its housing 20, silicone potting material, that is expressly recognized by the Specification of the ’421 patent when it states: “A common technique used to assist in fixturing the electrical sensor device 40 known within the automotive industry is to fill the internal cavity with a coating material such as a neutral silicone or the like for purposes of retaining placement position.” Ex. 1001, 13:56–60. Although the Specification also asserts that the sensor assemblies disclosed in the 421 patent “do not use or require the use of any such coating or filing agents or materials for any fixturing of the electrical sensor device 40,” id. at 13:61–64, limitation 1b merely requires that the “sensor device . . . is disposed within the internal cavity and attached therein to prevent movement of the device within the internal cavity,” id. at 30:25–27. Absent a persuasive argument to the contrary, we preliminarily conclude that Yamaguchi-727’s use of potting material to hold its module 6 in place within its housing 20 meets the requirements of limitation 1b.

“institute an inter partes review. The standard for instituting an inter partes review is set forth in 35 U.S.C. § 314(a), which provides that an inter partes review may not be instituted unless “there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” The Supreme Court has held that the Board, in a decision to institute under 35 U.S.C. § 314(b), may not institute review on less than all claims challenged in the petition. SAS Inst. Inc. v. Iancu, 138 S. Ct. 1348, 1355–56 (2018). Moreover, in accordance with our rules, “[w]hen instituting inter partes review, the Board will authorize the review to proceed on all of the challenged claims and on all grounds of unpatentability asserted for each claim.” 37 C.F.R. § 42.108(a) (2020); see also PGS Geophysical AS v. Iancu, 891 F.3d 1354, 1360 (Fed. Cir. 2018) (interpreting the statute to require “a simple yes-or-no institution choice respecting a petition, embracing all challenges included in the petition”). Applying those standards, and upon considering the Petition, the Preliminary Response, and the evidence of record, we determine the information presented shows a reasonable likelihood that Petitioner would prevail in establishing the unpatentability of at least one of the challenged claims of the ’027 patent. Accordingly, we institute an inter partes review of all challenged claims (i.e., 1–3, 5, 7–9, 11–13, and 15–22) of the ’027 patent, based on the grounds asserted in the Petition.” slip op. at 2

“We disagree with Patent Owner’s contentions that these disclosures indicate that Wilson’s patch would not meet the construction of “barrier material composition.” None of these disclosures even suggests that the base of Wilson’s patch is rigid as Patent Owner suggests. To begin with, the fact that the housing is “more rigid” provides no information about the absolute rigidness of the patch. See Ex. 1009, 9:16–21. As for the disclosure that the patch is contoured (id. at 3:35–67), Patent Owner provides only attorney argument to support its contention that the contour demonstrates that Wilson’s patch must be so rigid that it cannot be meet the claim limitation. In contrast, Petitioner demonstrates that Wilson discloses using the exact same materials described in the challenged patent (see Ex. 1001, 6:33–58 (noting “[e]lastomeric materials useful for forming the intermediate layer 24 include but are not limited to gum rubber, vulcanized natural rubber SBR . . . or comparable materials”); Ex. 1009, 3:49–55 (noting the patch may be constructed from natural rubber (NR), a preferred mixture of chlorobutyl rubber and natural rubber (CR/NR), or a preferred mixture of SBR and natural rubber (SBR/NR)), and provides detailed testimony from its expert to support its contentions (see Ex. 1003 ¶¶ 114–119).

Petitioner contends that the FDA Guidance provides the agency’s thinking and recommendations on the topic of orally dissolving tablets. Id. (citing Ex. 1005, 1). Petitioner argues that the FDA regulates the use of pharmaceutical compositions in the United States, and that Dohil’s formulations were intended to “be used in therapy for human patients,” and the initial testing of its formulations was conducted within the United States. Id. at 26–27 (citing Ex. 1002 ¶¶ 28, 49). Petitioner contends that a person of ordinary skill in the art, seeking to formulate budesonide into an orally disintegrating tablet, would have been motivated to follow the FDA Guidance that such a tablet should disintegrate within 30 seconds or less when tested using the USP <701> Disintegration Test.

“Petitioner contends that a POSA would have been motivated to follow the FDA Guidance (i.e., the guidance on the matter from the U.S. regulatory agency concerned with pharmaceuticals) in formulating Dohil’s rapidly dissolving lozenge or tablet containing budesonide. Id. at 25. According to Petitioner, a POSA seeking to formulate budesonide into an orally disintegrating pharmaceutical composition would have been motivated to follow the FDA Guidance that such a composition should disintegrate within thirty seconds or less when tested using the USP <701> Disintegration Test. Id. (citing Ex. 1053 ¶ 128). Petitioner also argues that a POSA would have had a reasonable expectation of success in doing so based on Dohil’s detailed description of how to formulate budesonide into a rapidly disintegrating lozenge or tablet. Id. (citing Ex. 1002 ¶¶ 27–41). According to Petitioner, formulating orally disintegrating tablets that dissolve within “several seconds to about a minute” would have been a routine exercise by 2009, the earliest possible priority date of the ’407 patent. Id. at 26 (citing Ex. 1005, 2; Ex. 1018, 434). Petitioner contends that, at that time, there were many orally disintegrating systems and products that were commercially available, which would have bolstered a POSA’s expectation of success. Id.

“Patent Owner further argues Nakazawa teaches away from Petitioner’s asserted modification in which Glaug’s lower non-perforated layer is added to Nakazawa’s diffusion sheet. Prelim. Resp. 42. Specifically, Patent Owner argues Nakazawa teaches that its embodiment in which the second absorbent material is wrapped in a hydrophilic sheet has the advantage of preventing leakage of super absorbent polymer (“SAP”) from the second absorbent material without impeding permeation of excretory fluid through the hydrophilic sheet. Id. at 43 (citing Ex. 1008 ¶ 85, Fig. 15). Patent Owner further relies on Petitioner’s argument that Nakazawa’s hydrophilic layer is analogous to the lower non-perforated layer in Glaug. Id. (citing Pet. 93–94). Therefore, Patent Owner argues, Nakazawa teaches that Glaug’s fluid acquisition system would impede permeation of fluid rather than promote it. Id. Patent Owner’s teaching away argument is unavailing based on the current record. Patent Owner improperly relies on Petitioner’s contention in its anticipation challenge based on Nakazawa, and characterizes it as an argument about Glaug. As further discussed in Section II.G below, Petitioner’s anticipation challenge is based on analogizing Nakazawa’s hydrophilic sheet to a core wrap feature identified in Patent Owner’s infringement contention in parallel district court litigation. See Pet. 92–93. Contrary to Patent Owner’s argument, Petitioner’s obviousness contention does not argue Nakazawa’s hydrophilic layer is analogous to Glaug’s nonperforated fibrous layer. Because Patent Owner is not properly characterizing Petitioner’s obviousness contention, Patent Owner’s teaching away argument is not persuasive.” slip op. at 24
