WOBURN, Mass., Feb. 26, 2026 (GLOBE NEWSWIRE) -- Biofrontera Inc. (NASDAQ:BFRI), a biopharmaceutical company specializing in the commercialization and development of photodynamic therapy ("PDT"), today announced that on February 23, 2026, the U.S. Patent Trial and Appeal Board (the "Board") issued a Final Written Decision finding all challenged claims of Sun Pharmaceutical Industries, Inc.'s U.S. Patent No. 11,697,028 (the "'028 Patent") to be unpatentable.

As previously disclosed in Biofrontera's filings with the Securities and Exchange Commission, in June 2024, Sun Pharma initiated proceedings against Biofrontera and certain of its affiliates in the U.S. District Court for the District of Massachusetts and the International Trade Commission alleging infringement of the ‘028 Patent and a related patent, U.S. Patent No. 11,446,512 (the "'512 Patent"). In response to these proceedings, Biofrontera challenged the validity of Sun Pharma's asserted claims by filing petitions for Inter Partes Review with the Board. The Board has now agreed with Biofrontera on all challenged claims of the ‘028 Patent.

Sun Pharma has the right to request a review of the decision or appeal it to the United States Court of Appeals for the Federal Circuit. The decision does not affect the petition filed by the Company relating to the ‘512 patent, which was denied review by the Patent Office on administrative, rather than substantive, grounds.

"Biofrontera is pleased with the Board's Final Written Decision.," commented Hermann Luebbert, CEO and Chairman of Biofrontera. "We remain focused on clinical research and development in the PDT space to better serve clinicians and improve their patients' lives."
