Kenneth B. Herman

Retired Partner

Ken has been litigating patents and other intellectual property for over 40 years – first with Fish & Neave and then with Ropes & Gray after the two firms merged. His trials have led to over $1,000,000,000 in collected damage awards for his clients. He has litigated technologies as diverse as optical waveguide fibers, sailboat winches, recombinant DNA and treatment for age related macular degeneration. Ken’s liberal arts background coupled with his pre-medical courses enables him to communicate complex technological issues effectively to lay judges and juries. Ken has litigated in state courts, federal courts and the International Trade Commission. He has also argued numerous appeals before the Court of Appeals for the Federal Circuit. Ken tried his first lawsuits while in law school as an intern for the local district attorney, and he has been trying cases ever since.
