“Had this case been determined by one other circuit… fundamental rules of subject preclusion would have allowed the PTAB’s resolution to dam UTC’s induced infringement declare.” – Petitioner Liquidia Applied sciences
Final week, biopharmaceutical firm Liquidia Applied sciences filed a petition for writ of certiorari with the U.S. Supreme Court docket to attraction a Federal Circuit ruling that affirmed induced infringement findings towards Liquidia following the patent at subject being invalidated on the Patent Trial and Attraction Board (PTAB). Within the petition, Liquidia argues that two earlier Supreme Court docket rulings result in a outcome opposite to the Federal Circuit’s willpower that the invalidation of patent claims on the PTAB don’t have preclusive impact on infringement litigation pending an attraction of the PTAB’s resolution.
Federal Circuit Affirms Induced Infringement Earlier than Affirming Patent Invalidation
The current attraction stems from competing New Drug Functions (NDAs) filed on the U.S. Meals & Drug Administration by Liquidia and respondent patent proprietor United Therapeutics Company (UTC). Each NDAs cowl strategies of treating pulmonary artery hypertension with inhaled formulations of treprostinil, which Liquidia sells as Yutrepia and UTC sells as Tyvaso. UTC filed a patent infringement go well with in Delaware district court docket in June 2020 and whereas Liquidia raised invalidity defenses in district court docket, it additionally filed for inter partes assessment (IPR) proceedings on the PTAB to problem UTC’s U.S. Patent No. 10716793, Treprostinil Administration by Inhalation.
After the PTAB invalidated all challenged claims of the ‘793 patent in Liquidia’s IPR, the Delaware district court docket issued a ruling affirming each the validity of the ‘793 patent’s claims and the jury’s induced infringement discovering towards Liquidia. Liquidia appealed to the U.S. Court docket of Appeals for the Federal Circuit, which issued a decision last July agreeing with the district court docket that the PTAB’s invalidation of the ‘793 patent’s claims didn’t take preclusive impact whereas UTC’s attraction of the ultimate written resolution was pending. Then final December, the Federal Circuit affirmed the PTAB’s remaining written resolution within the IPR invalidating UTC’s ‘793 patent claims.
Liquidia’s cert petition warns that grave penalties, together with the destabilization of the IPR course of by meritless appeals, will stem from the Federal Circuit’s resolution to affirm the induced infringement discovering in favor of UTC. The petitioner additionally notes that the ruling’s impacts will not be restricted to patent regulation and will permit an individual to take away any preclusive impact from any federal company ruling by submitting an attraction.
Commil, B&B {Hardware} Verify That Preclusive Impact Ought to Apply
Two latest Supreme Court docket selections ought to compel the Court docket to nix the induced infringement ruling towards Liquidia, the petition argues. The primary of those is Commil USA v. Cisco (2015). Though Commil held that subjective perception in a patent’s invalidity was not a protection to induced infringement, the Court docket’s ruling said: “To make certain, if on the finish of the day, an act that might have been… an inducement to infringe pertains to a patent that’s proven to be invalid, there is no such thing as a patent to be infringed.” Liquidia’s petition contends that Commil’s ruling is expressly grounded within the PTAB’s statutory framework and in the end “held what’s dispositive right here, ‘accused inducers who consider a patent is invalid have varied correct methods to acquire a ruling to that impact.’” Looking for an invalidity ruling by means of IPR proceedings on the PTAB is exactly what the Supreme Court docket advised events avoiding infringement legal responsibility in Commil, Liquidia causes.
Though B&B Hardware v. Hargis Industries (2015) handled a trademark ruling appealed from the Trademark Trial and Attraction Board (TTAB), the Court docket analyzed its personal prior selections and the Restatement (Second) of Judgments earlier than stating that “the place a single subject is earlier than a court docket and an administrative company, preclusion additionally typically applies.” Below that reasoning, the Court docket discovered that the TTAB’s probability of confusion findings had preclusive impact on trademark infringement litigation in district court docket. In B&B {Hardware}, the Court docket seemed for however discovered no evident statutory function eradicating preclusive impact from TTAB rulings, “simply because the Court docket itself did in Commil,” Liquidia argues. Following B&B {Hardware}, U.S. district courts and the Federal Circuit itself have dominated that TTAB and PTAB proceedings are practically indistinguishable for functions of subject preclusion.
Unique Jurisdiction for Patent Appeals Means Concern Unlikely to Percolate Elsewhere
Below peculiar guidelines of res judicata, or subject preclusion, remaining judgments of decrease tribunals are given preclusive impact regardless of the pendency of an attraction. “Each single circuit follows this rule as to decrease court docket rulings,” Liquidia contends. In contrast, the petitioner cites a number of examples of decrease courts expressing confusion as to the Federal Circuit’s rulings on the preclusive impact of IPR rulings when an attraction is pending. “Had this case been determined by one other circuit—which it couldn’t have been, given the Federal Circuit’s unique jurisdiction—fundamental rules of subject preclusion would have allowed the PTAB’s resolution to dam UTC’s induced infringement declare,” Liquidia argues.
Nothing within the textual content of the America Invents Act (AIA) gives any evident Congressional intent to foreclose the conventional operation of preclusion regulation in IPR proceedings, Liquidia concludes. Usually, courts favor administrative estoppel, and estoppel provisions like these codified at 35 U.S.C. § 315(e)(2) mirror that Congress supposed PTAB remaining written selections to have preclusive impact on civil actions in U.S. district court docket. Requiring petitioners to incorporate all potential invalidity arguments in an IPR petition or threat waiving these arguments in district court docket solely amplifies Congressional intent that preclusive impact would apply, based on Liquidia.
“[A]s a sensible matter, the Federal Circuit’s resolution on this case implies that a whole lot of invalidity determinations by the PTAB annually can be denied the preclusive results Congress supposed to present them,” Liquidia’s petition states. Additional percolation of his subject in different circuit courts is pointless, Liquidia argues, as patent appeals in regional courts of attraction are extraordinarily uncommon.
