Murata v. Daifuku: District Court Denies Preliminary Injunction Motion for a Second Time After Remand from Federal Circuit Based on Pending IPR and Previously Issued Stay
In September 2013, Murata filed a patent infringement action alleging that Daifuku infringed three of its patents (the "Original Patents"). A year later, in September 2014, Murata moved to amend its Complaint to add two patents that Murata alleged were also infringed by Daifuku (the "Additional Patents"). Daifuku filed an inter partes review ("IPR") of the Original Patents and then moved to stay the case pending the outcome of the IPRs.
The district court then stayed the case and simultaneously granted permission for leave to amend the complaint to add the Additional Patents. After the PTAB instituted review of the Original Patents, Murata moved to lift the stay with respect to the Additional Patents and moved for a preliminary injunction on the Additional Patents. Daifuku also filed IPRs with respect to the Additional Patents. The district court denied the motion for preliminary injunction as untimely because it declined to lift the stay.
