Strafford Webinars: Evolving PTAB Trial Practice

Schedule :

"Evolving PTAB Trial Practice: Navigating Complex Procedural Rules" scheduled for Thursday, May 25, 1:00pm-2:30pm EDT.

The Patent Trial and Appeal Board (PTAB) has become the forum of choice for disputing U.S. patent validity. Since its inception, parties have turned to the PTAB for its unprecedented speed, predictability and expert insight. A thorough understanding of this evolving landscape includes not only mastering the unique rules of this forum (including proposed changes), but also an ever changing body of Board informative decisions, and growing CAFC precedent.

Counsel must understand strategic leverage points presented by these proceedings to maximize both patent monetization potential and settlement opportunity.

Our panel will provide guidance to counsel on trends in PTAB trial practice, focusing on motion opportunities, amendment, concurrent reissue/reexamination, evidentiary opportunities, petition missteps and much more.

We will review these and other key issues:

  • Estoppel
  • Redundancy
  • Joinder
  • Motions to exclude
  • Supplemental evidence vs. supplemental information
  • Rehearing/appeal

After our presentations, we will engage in a live question and answer session with participants so we can answer your questions about these important issues directly.
