Post-Grant Proceedings

The America Invents Act (AIA) has created several new post-grant proceedings for third parties to challenge the validity of issued U.S. patents before the U.S. Patent and Trademark Office (USPTO). These proceedings have game-changing potential for challengers, providing a quicker and less expensive way to invalidate patents than district court litigation. Our attorneys can help clients chart a course through this evolving landscape.

The advantages of the new post-grant proceedings include the use of a standard that is more favorable to the challenger and involvement of a technically trained administrative law judge who hears such challenges. These proceedings also do not entail excessive discovery.

Ballard Spahr's Post-Grant Team is made up of experienced patent litigators and patent lawyers who hold Ph.D.s in a variety of fields and have experience handling both district court litigation and various post-grant proceedings. Our work includes helping clients use post-grant proceedings as part of a preemptive strategy to challenge patents before a product launch.

Even when other counsel has been hired to handle related district court litigation, Ballard Spahr has been engaged to conduct post-grant proceedings. Our attorneys have handled numerous USPTO proceedings, including the new procedures. In addition, we are well versed in internationally based post-grant and opposition proceedings.
