Titan Tire Corp. v. Case New Holland Inc.
A factor to be considered in granting a preliminary injunction is the patentee’s likelihood of success on the merits. In assessing this factor, a trial court should evaluate the alleged infringer’s evidence of invalidity as well as the evidence the patentee presents in rebuttal. The inquiry into the obviousness of a design patent is whether the claimed design would have been obvious to a designer of ordinary skill who designs articles of the type involved.
