Any result the lawyer or law firm may have achieved on behalf of clients in other matters does not necessarily indicate similar results can be obtained for other clients.

Second-chaired the winning trial team, obtaining a jury verdict in our client’s favor that the asserted patent was not infringed and invalid. At a follow-up bench trial, the team also obtained cancellation of an “incontestable” trademark by showing that the mark was not just descriptive, but generic.
