Mealey's (May 15, 2018, 1:54 PM EDT) -- WASHINGTON, D.C. — The Federal Circuit U.S. Court of Appeals on May 14 clarified two “basic” and “undecided” issues relating to “proper judicial administration in the wake of” TC Heartland LLC v. Kraft Foods Grp. Brands LLC, 137 S. Ct. 1514 (2017); according to the panel, Federal Circuit law governs the burden of proof for determining the propriety of venue under the patent venue statute, 28 U.S.C. § 1400(b), and the burden rests with a patent infringement plaintiff (In re: ZTE USA Inc., No. 18-113, Fed. Cir., 2018 U.S. App. LEXIS 12498)....
