Last week, Gilead Sciences, Inc. and the High Tech Inventors Alliance (the “Alliance”) led separate amicus curiae briefs in support of Cray, Inc.'s petition for a writ of mandamus seeking review of an Eastern District of Texas decision denying Cray's motion to transfer venue. [Please see our July 19, 2017 – TC Heartland Weekly Update for a summary of the petition.] Both groups argue that the Eastern District of Texas misinterpreted the Federal Circuit's ruling in In re Cordis, 769 F.2d 733 (1985) and that the district court's four-factor test for determining a “regular and established place of business” is awed.
