National Steel Car, LTD. v. Canadian Pacific Railway, LTD, et al.
Federal Circuit
Decided: January 29, 2004
Holding: “In conclusion, we hold that the district court abused its discretion in determining that NSC had demonstrated that CPR’s defenses lacked substantial merit and in granting the preliminary injunction. Based on the record before us, both CPR’s section 272 argument and its argument concerning the invalidity of the ‘575 patent on the basis of obviousness raise defenses with substantial merit.”
The court thus reversed the district court’s preliminary injunction.
