Equipped with a deep understanding of pharmaceutical litigation related to intellectual property and the Hatch-Waxman Act, Michael currently serves as lead trial counsel in several ongoing matters representing some of the largest pharmaceutical manufacturers in the world.

These matters pertain to Abbreviated New Drug Applications (ANDAs) for pharmaceutical products that utilize substances including fingolimod, bendamustine hydrochloride, and permetrexed, among many others, and involve the treatment of conditions including relapsing multiple sclerosis, chronic lymphocytic leukemia, advanced nonsquamous non-small cell lung cancer, and malignant pleural mesothelioma.
