Conditions of Stays Pending IPR, CBM and PGR

Since the creation of new post-grant proceedings before the Patent Trial and Appeal Board, U.S. district courts have ruled on 617 motions to stay pending inter partes review (IPR), covered business method review (CBM), and post-grant review (PGR). Most of those rulings either granted or denied a stay. However, in 27 rulings, courts granted the stay upon certain conditions, the most common of which was defendants’ agreement to 35 USC § 315(e) estoppel. In some cases, the stipulated estoppel was weaker than estoppel under § 315(e). In other cases, stay was conditioned on the PTAB reaching certain determinations that might impact the litigation.
