Judge Leonard P. Stark recently considered plaintiffs’ emergency motion to stay the date for service of plaintiffs’ responsive expert reports pending resolution of plaintiffs’ motion to strike defendants’ untimely invalidity contentions. Avanir Pharms., Inc. v. Actavis South Atlantic LLC, C.A. No. 11-704-LPS (Consol.) (D. Del. Mar. 19, 2013). Judge Stark granted plaintiffs’ motion finding that plaintiffs “would be unfairly prejudiced by having to prepare and serve responsive expert reports while their motion to strike is pending, as they would not know whether it is necessary to respond to all of the opinions expressed in Defendants’ expert reports.” Id. at 3.
