- Use claims: Cover specific therapeutic uses.
Scope of Claims in 7,417,067
Claim 1: Independent claim
The core claim typically encompasses a chemical compound with specified molecular structure parameters or a class of compounds. For example:
"A compound of formula I, or a pharmaceutically acceptable salt, ester, or prodrug thereof, wherein the structural variables are defined as..."
Claims 2–20: Dependent claims
Further specify:
- Variations in substituents
- Method of synthesis
- Methods of use
- Therapeutic indications
Key aspects of claim scope:
| Aspect |
Description |
| Chemical structure |
Defines the specific core or class of compounds |
| Functional groups |
Specifies permissible functional group variations |
| Pharmaceutical composition |
Claims formulations including salts, esters, or prodrugs |
| Therapeutic methods |
Claims specific methods of treatment with the compounds |
| Diagnostic methods |
Possible claims on use in diagnostics, if applicable |
Claim breadth considerations:
- Narrower claims specify specific chemical variants.
- Broader claims encompass a chemotype or class.
Implication: The scope governs the patent’s enforceability; overly broad claims risk invalidation for indefiniteness or lack of novelty, whereas narrow claims limit enforceability.
