2. Scope and Claims Analysis
2.1. Independent Claims Overview
| Claim Number |
Type |
Core Element |
Scope |
Notes |
| Claim 1 |
Composition |
A chemical entity characterized by a core scaffold with specific substitution patterns |
Broad; includes all compounds conforming to the defined structure |
Encompasses derivatives that retain core features |
| Claim 2 |
Method of Use |
Use of the compound for treating Disease X |
Therapeutic method claim, potentially enforceable against direct infringers |
Requires demonstration of efficacy in disease model |
| Claim 3 |
Formulation |
Pharmaceutical composition comprising the compound and excipients |
Is dependent on Claim 1 or 2, adds formulation scope |
Could extend to novel delivery systems |
Note: The precise language of the claims (not provided here) is critical, especially the Markush groups in composition claims, which define the chemical scope.
2.2. Dependent Claims and Their Limitations
Dependent claims typically narrow the scope, specifying particular substituents, stereoisomers, or dosage forms. For example:
| Claim Number |
Features |
Implication |
| Claim 4 |
Stereochemistry at position X |
Limits to a specific stereoisomer, potentially affecting patent breadth |
| Claim 5 |
Use with a specific co-therapy |
Extends patent coverage to combination therapies |
The detailed language of these claims determines the enforceability and the potential for design-arounds.
