When a motion for a stay in view of an inter partes review (“IPR”) or covered business method review (“CBM”) is filed in a related district court litigation, the district court will grant the motion more often than it will deny it. Our study1 indicates that orders for disputed motions to stay litigation in view of IPR or CBM are granted 73.4%2 of the time.

Unsurprisingly, the district courts with the most active patent dockets also have the most orders ruling upon disputed motions to stay pending IPR or CBM, (e.g., District Court of Delaware (25 decisions); Northern District of California (18 decisions) and the Eastern District of Texas (10 decisions)). The Northern District of California had the highest percentage of granted IPR stay motions: 83.33%. Meanwhile, the Eastern District of Texas had the lowest percentage of granted IPR stay motions: 50%.
