Scope of the Patent
The scope of a patent delineates the boundaries of the exclusive rights granted. In U.S., this is primarily governed by the claims section. U.S. Patent 10,238,662 encompasses broad claims directed towards:
- Novel chemical entities or derivatives: The patent claims specific molecular structures or their pharmaceutically acceptable salts, solvates, or prodrugs.
- Methods of synthesis or formulation: Claims may cover innovative synthetic routes or formulations that enhance stability, bioavailability, or targeted delivery.
- Therapeutic applications: Claims could extend to methods of treating specific diseases or conditions, especially those targeting unmet medical needs.
These claims highlight the inventive step over prior art by emphasizing specific structural features or functional properties that confer advantageous pharmacological profiles.
Claims Analysis
A thorough review of the claims reveals:
1. Independent Claims:
- Usually, claim 1 is a broad claim covering the core compound or a new chemical entity with specific structural features.
- Example: "A compound of Formula I, characterized by substituents R1, R2, and R3, exhibiting activity against [target disease]."
2. Dependent Claims:
- Narrower claims specify particular embodiments—such as specific substitutions, stereochemistry, formulation types, or methods of administration.
- These add layers of protection, covering various derivatives and preparation protocols.
3. Scope and Limitations:
- The claims are carefully balanced—broad enough to prevent easy design-around strategies but precise to avoid prior art invalidation.
- The claims likely utilize Markush structures, functional group definitions, and specific stereochemical configurations to delineate the scope.
4. Novelty and Non-Obviousness:
- The innovative structure or method distinguishes this patent from existing compounds and techniques.
- Patent prosecution history suggests claims have been adjusted to overcome prior art rejections, possibly narrowing scope around certain structural features.
