Focuses on contested matters before the U.S. Patent Office and Federal Courts, representing both IP owners and accused infringers. He has served as counsel in four full trials in a variety of technical fields. Mr. Kosma approaches litigation like a businessman and relies on instinct to get results, whether it be keeping clients out of the court room altogether, taking a case through trial, or obtaining record settlements.

With a heavy emphasis in the medical, computer, electrical and mechanical arts, Mr. Kosma is experienced in all aspects of patent law, from drafting and prosecution, to pre-suit investigations, through trial and appeal. He has argued in numerous federal district courts across the country, and has successfully assisted clients before the U.S. Court of Appeals for the Federal Circuit.

Mr. Kosma’s litigation experience has come in all shapes and sizes, ranging from successfully winning a contract case on summary judgment for a small manufacturing company, to successfully asserting a solo inventor’s patents against large companies. Along with his litigation experience, Mr. Kosma has also been involved in successfully implementing patent licensing programs.

Since the implementation of the America Invents Act, Mr. Kosma has combined his patent litigation and prosecution experience to represent clients in over ten Inter Partes Review (IPR) and Cover Business Method Review (CBM) proceedings before the PTAB. He has argued and managed all aspects of IPR/CBM practice before the PTAB, and continues to emphasize his focus on this new and important venue in patent litigation.
