Ex Parte Reexamination
Many clients come to Bill to assist with ex parte reexamination. Whether to invalidate a competitor’s patents during litigation or to protect the patent holder who is being threatened, Bill has extensive experience.
Bill’s success rate for invalidating patents with ex parte reexamination is 95%. Bill is familiar with both common and unusual reexamination tactics. As a result, Bill can often successfully invalidate a patent or anticipate arguments which provides valuable time to bolster a patent holder’s position.
We have found that ex parte reexamination can be a less expensive option (compared to litigation or inter partes reexamination) to attack and invalidate an aggressor’s patents. This is a valuable tool that is often overlooked in some law firm’s eagerness for more expensive options.
Bill has also conducted numerous seminars in strategic use of ex parte reexamination.
