Case Brief Summary & Legal Analysis
tl;dr: Following a patent infringement verdict, the court denied the defendant’s motion for attorney’s fees, finding no inequitable conduct. It also denied the plaintiff’s motion for enhanced damages for pre-lawsuit willfulness because no damages were awarded for that specific period.
Legal Significance: This case illustrates the high bar for proving inequitable conduct under the Therasense standard and clarifies that enhanced damages for willful infringement under 35 U.S.C. § 284 require a corresponding award of actual damages for the period of willful conduct.

Case Facts & Court Holding
Key Facts & Case Background
Plaintiff ABT Systems sued Defendant Emerson Electric for infringing two patents, the ‘017 and ‘268 patents. Just before trial, ABT executed a covenant not to sue on the ‘268 patent. A jury found Emerson infringed the ‘017 patent and awarded $311,379 in damages, but only for the period after the lawsuit was filed on November 5, 2009. In a special interrogatory, the jury found Emerson’s infringement was willful before the lawsuit was filed, but not after. Post-trial, Emerson moved for attorney’s fees under 35 U.S.C. § 285, arguing the case was “exceptional” because ABT’s inventor, Rudd, engaged in inequitable conduct during the prosecution of the ‘268 patent. Emerson alleged Rudd failed to disclose his own test results of a prior art device (the Honeywell PC8900) to the PTO, despite disclosing the device’s product literature. ABT moved for enhanced damages under 35 U.S.C. § 284 based on the jury’s finding of pre-lawsuit willfulness. Emerson’s defense at trial was that its products used technology from an abandoned prior art patent and that the ‘017 patent was obvious.
