Claim scope and enforceability
- Strengths: Claims are designed to be "self-supporting" and cover multiple forms of the compound and methods of treatment.
- Weaknesses: The scope might be limited if the claims are narrowly drafted around specific molecular structures or formulations.
- Patentability criteria: Meets novelty, non-obviousness, and utility requirements, based on available prior art searches.
Likely legal challenges or gaps
- Patentability over prior art: The claims may face challenges if similar compounds or formulations are documented.
- Claim construction: The precise language limits scope to specific embodiments; overly narrow claims risk easy invalidation.
- Evergreening risks: If the patent claims a minor modification of a prior patent, it might be vulnerable to invalidation.
