Black & Decker Inc. v. Robert Bosch Tool Corp., No. 04 C 7955, 2006 WL 3783006 (N.D. Ill. Dec. 22, 2006) (St. Eve, J.).

Having already denied plaintiff summary judgment on defendant’s inequitable conduct defense (here) and increased damages 50% and awarded prejudgment interest compounded monthly (here), the Court denied defendant’s motions for judgment as a matter of law, to alter the willfulness judgment and for a new trial.  The Court’s denial of these sort of post-trial motions is far from surprising, in light of the substantial burdens that must be overcome to win them.  Of special note, defendant argued that the jury’s willfulness determination was not valid because the evidence relied upon was defendant’s knowledge of a competing product that it believed to constitute patented technology, not defendant’s knowledge of the specific patents that were infringed.  The Court held that the relevant inquiry is the infringer’s knowledge of the existence of patent rights, not specific patents.
