Written by Customer Service on . Posted in Public Companies.

After Reviewing the Ruling, Heron Believes It has Substantial Grounds for Obtaining Reversal in an Appeal

CARY, N.C., June 02, 2026 (GLOBE NEWSWIRE) — Heron Therapeutics, Inc. (Nasdaq: HRTX) (“Heron” or the “Company”), a commercial-stage biotechnology company, today announced that the U.S. District Court for the District of Delaware issued a decision in the patent litigation between Heron and Azurity Pharmaceuticals, Inc., Azurity Pharmaceuticals India LLP f/k/a Slayback Pharma India LLP, and Slayback Pharma LLC (“Azurity”), with respect to CINVANTI® (aprepitant) injectable emulsion, holding that the asserted claims of Company’s U.S. Patent Nos. 12,115,255 and 12,290,520 are invalid. This decision has no impact on any prior settlement agreement related to CINVANTI® (aprepitant) injectable emulsion or APONVIE® (aprepitant) injectable emulsion. Heron intends to appeal the decision to the United States Court of Appeals for the Federal Circuit, a court that specializes in patent disputes.

“We are disappointed with this initial result of the litigation and will vigorously pursue our appeal and all available remedies, including equitable relief if necessary, as we continue to defend our intellectual property rights,” said Craig Collard, Chief Executive Officer of Heron.
