The case of the day is AIS GmbH Aachen Innovative Solutions v. Thoratec LLC (9th Cir. 2019). AIS and Abiomed Europe GmbH sought leave to take discovery under § 1782 in aid of a patent infringement case Abiomed had brought against Thoratec in Germany involving heart pumps. A magistrate judge granted the application and ordered Thoratec to produce three samples of its heart pump. Thoratec objected to the magistrate judge’s decision, but the date for compliance came before the district judge had made a decision on the objection, so Thoratec also petitioned for a writ of mandamus, and the Ninth Circuit issued a temporary stay. The district judge then overruled the objection, and Thratec appealed. In today’s decision, the court affirmed.
