Murata Mach. USA, Inc. v. Daifuku Co., Ltd., No. 15-2094 (Fed. Cir. 2016)
Annotate this CaseMurata and Daifuku manufacture and maintain automated material handling systems that use robotic vehicles suspended in semiconductor cleanrooms to move and manipulate semiconductor components. Murata sued Daifuku, alleging infringement. Daifuku petitioned the Patent Trial and Appeals Board for inter partes review of three patents and moved to stay the litigation pending the outcome, citing the traditional three-factor test, considering: stage of the proceedings; potential for the stay to simplify; and undue prejudice to the non-moving party or a clear tactical advantage for the moving party. Murata asked that the court consider a fourth factor: potential for a stay to reduce the burden of litigation on the parties and the court. The court, relying on four factors, stayed the case, but granted leave for Murata to amend its complaint to add two Additional Patents. Murata amended, moved to lift the stay with regard to the Additional Patents, and sought a preliminary injunction. Again applying the four factors, the court declined to lift the stay, then stated that “[b]ecause the court has now declined to lift the stay, the Motion for Preliminary Injunction is denied without prejudice to renew at a later date, if appropriate.” The Federal Circuit upheld refusal to lift the stay, but found that the “cursory denial” did not satisfy FRCP 52(a)(2), which requires that a court state findings and conclusions supporting denial of a preliminary injunction.
