2.2 Structural Scope (Claim 1)
- Core Scaffold: The claim centers on a heterocyclic ring system, possibly a modified pyrimidine, purine, or other heteroaryl core.
- Substituents: R groups can be various, with specific ranges or substituents explicitly disclosed.
- Variability: The claim encompasses derivatives with modifications at defined positions, enabling broad protection for different analogs.
2.3 Method and Composition Claims
- Pharmaceutical compositions claim may specify dosage forms (e.g., tablets, injectables), concentration ranges, and vehicle components.
- Method of treatment claims typically articulate therapeutic indications, such as reducing inflammation, inhibiting tumor growth, or antiviral activity.
3. Claim Scope and Patent Language
| Term Type |
Definition |
Implication for Scope |
| "Comprising" |
Open-ended, includes additional elements |
Broader scope, includes variants |
| "Consisting of" |
Closed-ended, excludes additional elements |
Narrower protection |
| "Configured to" |
