Desmarais LLP handles all stages of litigation. We have successfully tried cases before juries and judges throughout the country, as well as before administrative bodies and arbitration panels. At the appellate level, we have successfully briefed and argued cases before numerous appellate courts.

The cases that we litigate span a wide range of subjects and technologies. We have obtained successful trial results for our clients—both plaintiffs and defendants—in dozens of patent infringement cases and other intellectual property disputes, concerning technologies as diverse as semiconductors, telecommunications, software, consumer electronics, pharmaceuticals, medical devices, biotechnology, chemicals, and transportation. On appeal, we have preserved both offensive and defensive victories for our clients in wide-ranging subject matter areas, obtained the reversal of adverse results, and steered the development of the substantive law in our clients' interests.
