DUSA Pharma sues Biofrontera over patents
Indian drug major Sun Pharmaceutical Industries’ (SUN: BO) US dermatology business DUSA Pharmaceuticals has filed trade secret misappropriation and tortious interference claims in an ongoing patent infringement lawsuit against Germany-based skin cancer specialist Biofrontera (FSE: B8F) and subsidiaries in the US District Court for the District of Massachusetts.
The lawsuit alleges patent infringement of DUSA's patents, US 9,723,991 and US 8,216,289 covering DUSA's product, Levulan Kerastick (aminolevulinic acid HCl) for topical solution, 20% used with DUSA's BLU-U Blue Light Photodynamic Therapy Illuminator.
In its amended complaint, DUSA additionally alleges that the Biofrontera defendants misappropriated confidential and trade secret information from DUSA and improperly obtained confidential DUSA information from former DUSA employees to sell and market defendants' own products. The lawsuit seeks an assessment of both damages and injunctive relief against the Biofrontera defendants.
