What are the benefits?

One of the benefits of working with SLW is that our claim mapping capability and our thorough patent work makes it less likely that your patents will be reduced or demolished by a reexamination. Claims can only be considered invalid in light of prior art, publications and patents that precede the filing of the challenged patent application.

During the reexamination process, the patent owner and its attorneys communicate with the U.S. Patent & Trademark Office (USPTO) to alter claims, avoiding newly revealed art that poses a challenge to the patent grant. The claims emerging from the reexamination process are valid over the prior art. Art that is neutralized via reexamination can’t effectively be used as a trump card in litigation.
