Joint Defense Agreement with IPR Petitioner Does Not Require Estoppel as a Condition of Stay

Aug 14, 2014

Reading Time : 1 min

In granting the stay without estoppel, the court reasoned that estoppel was not necessary because PTAB decisions become part of a patent’s file history and as such, become part of the record for any court to consider in addressing those same arguments. In addressing plaintiff’s fairness argument that it would be unfair for defendant to obtain the benefit of IPR proceedings without being bound by the arguments raised therein, the court reasoned that it would be more unfair to bound the defendant to arguments raised by a third party in a proceeding that defendant had no control over. Accordingly, the court found that regardless of the JDA and use of the same law firm by defendant and petitioner, estoppel was not a necessary condition to the stay.

The Federal Circuit recently denied a petition for a writ of mandamus that challenged the PTO Director’s reliance on “settled expectations” to discretionarily deny two inter partes review (IPR) petitions. In so doing, the court explained that, while it was not deciding whether the Director’s use of “settled expectations” was correct, the petitioner’s arguments about what factors the Director may consider when deciding whether to institute an IPR or post-grant review (PGR) are not generally reviewable and did not provide sufficient basis for mandamus review here.
