Judge Darrah, after finding each of the eleven patents-in-suit unenforceable for inequitable conduct, held that the suit was exceptional based upon the inequitable conduct, the filing of several frivolous claims which were previously dismissed and misconduct at trial, providing the Court the discretion to award attorney’s fees. The court also did a detailed analysis of defendants’ Bill of Costs and awarded defendants some or all of their requested costs for service of process, court reporters, witnesses and experts, among others. Of note, the Court held that expert fees, including the expert’s hourly rates, were recoverable for time spent on expert reports, deposition and related preparation, and other time spent in responding to discovery, but not for time spent attending other expert depositions in the case.
