The magazine cited his role as part of the Morgan Lewis team that carried “a small technology company to a $140 million victory” in ActiveVideo v. Verizon in the Eastern District of Virginia. The win was one of the five largest patent damage awards in the United States, with a total expected recovery in excess of $260 million.
