In Norman IP Holdings v. TP-Link Technologies, Co., et al., the Defendants moved to stay the litigation pending completion of an inter partes review involving the patents-in-suit. The plaintiff did not respond to the motion. Thereafter, the court granted the motion and stayed the litigation pending completion of the IPR involving claim 6 of the ‘597 Patent.
Plaintiff’s complaint alleges ADTRAN infringes U.S. Patent Nos. 5,502,689 (the “‘689 Patent”), 5,530,597 (the “‘597 Patent”), and 5,592,555 (the “‘555 Patent”). Specifically, the plaintiff asserts claims 5 and 6 of the ‘689 Patent, claims 1-6, 10, and 11 of the ‘597 Patent, and claims 10, 12, and 51 of the ‘555 Patent against ADTRAN, the sole remaining defendant at the time the court decided the stay motion. The court noted that there have been 10 petitions for post-grant review of the three patents asserted by Norman. A total of 33 separate claims from the asserted patents have been canceled in the four proceedings that have been completed. The remaining six proceedings were pending at the time of the filing. In concurrent litigation, Norman alleged Nissan North America, Inc. (“Nissan”) infringes the same asserted claims of the ‘689 and ‘597 patents. Nissan filed a petition for IPR as to claim 6 of the ‘597 patent and claims 5 and 6 of the ‘689 patent. On September 23, 2014 PTAB granted Nissan’s petition for IPR as to the asserted claims in the ‘689 and ‘597 patents. During the October 7, 2014 hearing ADTRAN agreed, if the court granted a stay of the present litigation, “to be estopped as to invalidity contentions raised and adjudicated in the [Nissan] IPR proceedings.”
