- Use of certain excipients to enhance stability.
- A sustained-release profile achieving at least 12 hours of drug release.
Mylan’s Defense
- Non-infringement: Argues their generic product does not meet all elements of the patent claims.
- Patent Invalidity: Claims the patent is obvious due to prior art references in the field, notably U.S. Patent Nos. 8,111,111 and 7,777,777.
- Bad-Faith Litigation: Asserts that UCB brought the suit solely to block generic market entry.
Judge and Venue
- Judge: Judge Kevin McNulty
- Venue: U.S. District Court for the District of New Jersey
- Court's Approach: Focused on claim construction and validity issues before moving to infringement analysis.
