6. Critical Assessment of the Claims
6.1 Potential Vulnerabilities
- Prior Art Overlap: Given existing patents with similar structures, the '195 patent's claims must demonstrate inventive step.
- Claim Breadth: Excessively broad claims risk invalidation; need balanced scope.
- Lack of supporting data: Insufficient experimental or clinical data can weaken validity.
6.2 Opportunities
- Claims on Stereoisomers or Salts: Focusing on specific forms can strengthen enforceability.
- Method of Manufacturing Claims: Enhances patent robustness and deterrence.
- Delivery Mechanisms and Compositions: Complementary claims can broaden protection.
7. Policy and Legal Considerations
- U.S. Patent Laws: Must comply with 35 U.S.C. § 101 (patent eligibility), §102 (novelty), §103 (non-obviousness).
- Inter Partes Review (IPR): The patent may face challenges based on prior art submitted post-grant.
- Research & Development Exemptions: The patent's claims could be challenged if methods are deemed obvious or trivial.
