Course Materials

This CLE course will provide guidance to patent counsel on the new preissuance submission rules and offer best practices for deciding whether and how best to file a preissuance submission on a competitor’s or potential competitor’s patent application and for monitoring competitors.


The America Invents Act ushered in many changes for patent prosecution, including allowing preissuance submissions, which went into effect on Sept. 16, 2012. The new preissuance submissions permit third parties to intervene in the prosecution of pending patent applications.

Preissuance submissions give third parties a mechanism to bring relevant prior art and other information to the USPTO to try and limit the scope of the patent application. Before deciding to submit prior art, counsel must consider the risk that it may actually make the patent stronger.

In addition to weighing the advantages and disadvantages of a pre-grant submission, competitors should monitor pending patent applications, particularly in highly competitive industries.

Listen as our authoritative panel of patent attorneys discusses the final rules published by the USPTO and examines pros of the process and the limitations. The panel will offer strategies for deciding whether and how best to file a preissuance submission of prior art on a competitor’s or potential competitor’s patent application and for monitoring competitors.

  3. Strategy
