“Mr. Bauer further testifies: For electric-powered breast pumps, the only two options for providing electricity to the pump was either via a wire plugged into an outlet or via a battery, as would have been well-known to a POSITA. It would have been obvious for a POSITA to utilize a battery as the power source for Furrer’s pump as it was one of the two available options and would have provided known benefits. Ex. 1003 ¶ 93. As to why this a person of ordinary skill would have chosen the option of a battery powered breast pump, Mr. Bauer testifies that: Selection of battery power for Furrer’s pump would have beneficially provided a portable system that was usable during travel. Additionally, such a configuration would have allowed the user to move freely about a room, or be positioned in a location within a room without being tethered to a wall plug, allowing the user to, for example, sit or lay in the most convenient location while using the system without having to worry about being close to an outlet. Such mobility provided by selecting battery power for Furrer’s pump would have particularly aligned with Furrer’s suggestion for a ‘hands-free’ and discrete solution. Id.

“A claim is unpatentable under 35 U.S.C. § 103 if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the relevant art.

“We find that Petitioner has made a threshold showing that the ’558 Provisional does not provide written description support for claim 1’s pharmaceutical solution consisting of each of the recited elements, including n-dodecyl beta-D-maltoside. It is true that “n-Dodecyl β-D-maltoside” can be found listed in the SIGMA Catalog. Ex. 1026, 316. But Dr. Donovan’s testimony helps put that listing in context. It is merely one among well over 100 ionic and non-ionic detergents listed in the cited six pages of the SIGMA Catalog. See 1026, 316–321; Ex. 1062 ¶ 50. When further considered in the context of paragraphs 150–152 of the ’558 Provisional, which generically suggest that “enhancer” compounds can be used in “some embodiments”—then introducing at least 15 classes of potential enhancers16 including “preferred” lysophospholipids and acyl carnitines—the listing of n-dodecyl beta-D-maltoside among at least 150 biological detergents in the SIGMA Catalog is even more remote. Moreover, although satisfaction of the written description requirement is not limited to what is exemplified in a priority application, none of the ’558 Provisional’s examples use any “enhancer,” much less any detergent, any alkyl glycoside, or n-dodecyl beta-D maltoside in particular. The 16 The ’558 Provisional suggests that whether “a given compound” will function as an “enhancer” in a formulation requires testing.

Petitioner did not establish that Gwozdz’s disclosure of “penetration enhancers” finds support in the Gwozdz Provisional. Pet. 22. Conversely, Patent Owner shows that the phrase is absent in the Gwozdz Provisional. Prelim. Resp. 37.20 Based on this record, we determine that Gwozdz’s mention of “penetration enhancers” is not prior art to the 19 Patent Owner argues this “penetration enhancers” disclosure in Gwozdz is not prior art regardless which of the disputed priority dates (March 28, 2008, or March 27, 2009) one accords to the challenged claims. Prelim. Resp. 33. 20 We also agree that collateral estoppel does not bar Patent Owner from challenging Gwozdz’s prior-art status in this case. Patent Owner’s apparent concession that Gwozdz was prior art during the 451 IPR does not equate to the issue being actually litigated. Prelim.

“of whether we exercise our discretion to deny institution under 35 U.S.C. § 314(a). Rather, when considering the Fintiv factors, we “take[] a holistic view of whether efficiency and integrity of the system are best served by denying or instituting review.” Fintiv at 6. Here, factors one and six are neutral, factors two and three weigh against discretionary denial, and factors four and five favor denial. We assign less weight to the existence of an overlap in asserted claims and prior art, in view of there being no trial date scheduled in the District Court case and no persuasive evidence that the court’s trial date would be expected to be significantly before the due date of our Final Written Decision. Therefore, after weighing all of the factors, we determine that the facts in this case that weigh against exercising discretion outweigh the facts that favor exercising discretion.
