Narrative Opinion Summary
This case involves an appeal by Iolab Corporation against the judgment of the United States District Court for the Southern District of Florida concerning the validity of U.S. Patent No. Re. 32,525 under 35 U.S.C. § 102(f) regarding nonjoinder and the award of attorney fees. Initially, the district court granted judgment as a matter of law (JMOL) in favor of Jaswant S. Pannu, ruling the patent was not invalid. Iolab argued that the patent was invalid due to the nonjoinder of William Link as an inventor and failure to disclose the best mode as per 35 U.S.C. § 112. The appellate court reversed the JMOL and the attorney fee award, citing collateral estoppel based on a prior case, which barred Pannu from asserting the patent’s validity. Moreover, the court found the district court's determination of the case as 'exceptional' to be in error, leading to the reversal of the attorney fee award. The decision underscores the application of collateral estoppel in patent litigation and the criteria for deeming a case 'exceptional' in awarding attorney fees.
