Xitronix Corp. v. KLA-Tencor Corp., No. 18-50114 (5th Cir. 2019)
Annotate this Case
At issue in this case was whether a jury should hear Xitronix's claim that KLA-Tencor violated the Sherman Act's prohibition of monopolies by obtaining a patent through a fraud on the U.S. Patent and Trademark Office (PTO).
The Fifth Circuit could not conclude that the Federal Circuit's decision to transfer this case to it was plausible, given the Supreme Court's and Congress's decisions to the contrary. The court held that the case belongs in the Federal Circuit because it presented a standalone Walker Process claim and there are no non-patent theories that would divert it to the Fifth Circuit. The court held that, under any reading of Gunn v. Minton, 568 U.S. 251 (2013), the court would deem it implausible that it could decide this appeal. Therefore, the court transferred the case back to the Federal Circuit.
