Narrative Opinion Summary
This case involves Takeda Pharmaceutical Company, Ltd., defending its U.S. Patent No. 4,687,777, which covers the diabetes drug pioglitazone, against challenges from generic manufacturers Alphapharm Pty. Ltd., Mylan Laboratories, Inc., and others. The defendants filed Paragraph IV certifications under the Hatch-Waxman Act, claiming the patent was invalid, but the court found these assertions baseless and pursued in bad faith. The defendants were accused of litigation misconduct for failing to provide a factual basis for their claims and for engaging in frivolous legal tactics. The court deemed the case exceptional under 35 U.S.C. § 285, warranting the award of attorneys' fees to Takeda. Alphapharm's legal strategy was criticized for relying on an unfounded obviousness argument, while Mylan's inequitable conduct claim was dismissed as frivolous. The court found both defendants infringed the patent by filing ANDAs for generic pioglitazone before the patent expired. Ultimately, the court granted Takeda's motion for attorneys' fees due to the defendants' conduct throughout the litigation.
