Scope of the Patent
The core scope of CN117695286 hinges on the claims, which define the extent of legal protection granted. In the pharmaceutical context, patent scope often revolves around novel chemical entities, formulations, methods of use, or manufacturing processes.
Types of Claims
-
Compound Claims
These claims specify particular chemical structures, often represented via chemical formulas, substituents, or stereochemistry. If the patent comprises such claims, their scope covers specific molecules with defined structure-activity relationships.
-
Use or Method Claims
These claims extend protection to specific therapeutic uses or methods of administering the compound, potentially covering treatment of particular diseases or conditions.
-
Formulation or Composition Claims
Protecting pharmaceutical compositions involving the claimed compounds alongside excipients, carriers, or specific formulations is typical.
-
Process Claims
If applicable, process claims outline methods of synthesis or manufacturing, offering protection to innovative production techniques.
Claim Breadth and Validity Considerations
-
Independent vs. Dependent Claims:
Independent claims often delineate the broadest scope—such as a general chemical class or therapeutic use—while dependent claims narrow this to specific embodiments.
-
Structural vs. Functional Claims:
Structural claims specify chemical structures, offering precise protection, whereas functional claims (e.g., "a compound exhibiting activity against XY") are broader but may face validity challenges.
-
Novelty and Inventive Step:
For claims to be enforceable, they must distinguish from prior art. Given China's rapid pharmaceutical patent growth, the claims likely revolve around innovative structures or uses that fill unmet medical needs.
