Our IP practice prosecutes patents before the USPTO, EPO, and CNIPA, and manages global portfolios for technology and life sciences clients. We have tried patent cases to verdict in the Eastern, Northern, and Central Districts of California, and before the Federal Circuit.

Our prosecutors are also our trial lawyers — the claims we draft are the claims we litigate.
