Idorsia Pharmaceuticals, Ltd. appeals the district court’s summary judgment upholding the U.S. Patent and Trademark Office’s patent term adjustment (PTA) deter- mination for U.S. Patent No. 8,518,912. Specifically, Idorsia challenges the PTO’s calculation o f “A Delay,” whereby a patent’s term is adjusted when the PTO fails to respond to certain events or filings by statutorily enumer- ated examination deadlines.
