What are the key claims of CN102276606?
Core Claims Overview
The patent contains independent claims defining the distinct aspects of the invention, supported by a series of dependent claims that specify particular embodiments or variations.
| Claim Type |
Description |
Scope |
| Independent Claims |
Define the main invention—likely a chemical compound, its preparation, or a therapeutic method. |
Cover broad classes of compounds or methods, ensuring wide protection within or related to the core compound. |
| Dependent Claims |
Narrower claims that specify particular substituents, concentrations, formulations, or uses. |
Provide protection for specific embodiments, formulations, or applications. |
Example Claim Structure (Hypothetical)
- Claim 1 (independent): A pharmaceutical composition comprising a compound of structural formula X, or a pharmaceutically acceptable salt thereof, for use in treating Condition Y.
- Claim 2 (dependent): The composition of claim 1, wherein the compound has a specific substitution at position Z.
- Claim 3 (dependent): The method of manufacturing the composition of claim 1 involving process A.
Claim Analysis Key Points
- Claims likely focus on a specific chemical entity with novel properties or synthesis pathways.
- The scope extends to salts, polymorphs, or formulations with therapeutic efficacy.
- Therapeutic indications—such as treatment of a specific disease—are specified, which can limit or expand enforceability depending on claim wording.
