Case Overview
Gilead Sciences, Inc. filed patent infringement litigation against David Kappos, then Director of the United States Patent and Trademark Office (USPTO), concerning the patent application process for its hepatitis C drug, sofosbuvir (sold as Sovaldi). The case was filed in the District of Columbia in 2012, involving issues related to patent transparency and procedural integrity at the USPTO.
Key Aspects of Litigation
Core Issues
- Patentability of sofosbuvir: Gilead contested objections raised during patent prosecution, which they claimed were improperly handled by the USPTO.
