Formulations and Compositions: It also encompasses pharmaceutical compositions containing the claimed compounds, including dosage forms and combinations with other active agents.
The scope is designed to strike a balance between broad coverage — capturing various derivatives and formulations — and specificity, preventing easy design-arounds.
Analysis of the Claims
The claims are sectioned primarily as independent and dependent types.
Independent Claims
The core claims define the chemical entity. For instance, an independent claim likely reads:
"A compound of formula I, [structure formula], wherein R1, R2, R3, etc., are as defined, with substituents that confer activity against [target biomolecule or disease]."
These claims aim to cover a broad spectrum of compounds sharing a core scaffold but allowing variations at specific positions.
Dependent Claims
Dependent claims specify particular embodiments, such as:
- Specific substituents at R1, R2, R3, etc., leading to more narrow protections.
- Particular physical states, such as crystalline forms, salts, or solvates.
- Specific methods of synthesis or administration.
Claim Language and Strategy
The patent employs functional language, such as "wherein R1 is independently selected from," to maximize breadth. Additionally, it includes claims directed toward pharmaceutical uses and compositions, emphasizing therapeutic applicability.
Implication: The scope is expansive, covering various derivatives and formulations, with a primary focus on the chemical class and its applications. The language ensures broad coverage of would-be competitors and derivatives while maintaining enforceability through specific dependent claims.
