Providing Insightful Litigation Support

Rich's experience as a patent prosecutor allows him to bring valuable insight to the client team during patent disputes. Working hand-in-hand with the litigation team, Rich helps strategize and execute on the various Patent Office proceedings that typically accompany infringement accusations and litigation.
