The patent emphasizes aspects such as composition, method of manufacture, and therapeutic use, thereby offering broad protection regarding the drug's formulation and administration methods.
Scope and Claims Analysis
Claims Structure and Hierarchy
The claims define the legal boundaries of the patent and are generally divided into:
- Independent Claims: Broad claims covering the core invention.
- Dependent Claims: Narrower claims, elaborating on specific embodiments or features.
A thorough review reveals that EP3654952 contains:
- One broad independent claim covering the drug composition or formulation.
- Multiple dependent claims, detailing specific excipients, concentrations, forms of administration, or manufacturing processes.
Independent Claims
The primary independently claim(s) delineate:
- Composition features: Including active pharmaceutical ingredient (API) type, dosage, and formulation specifics.
- Therapeutic indications: Such as treatment of particular conditions within the scope.
- Method of use or preparation: Covering steps or techniques associated with the drug's manufacturing.
E.g., an illustrative independent claim might read:
"A pharmaceutical composition comprising [API], wherein the composition exhibits [specific feature], and is suitable for administering [dosage form] to treat [disease]."
The scope extends to various APIs or combinations, depending on the phrasing.
Dependent Claims
Dependent claims narrow this scope, specifying:
- Particular ranges of API concentrations.
- Specific excipients or carriers.
- Preferred dosages or administration routes.
- Manufacturing techniques, such as lyophilization or encapsulation.
- Stability or bioavailability enhancements.
These claims refine the scope, offering protection for embodiments with specific parameters and increasing enforceability against infringing products that deviate from these narrowed features.
Scope Interpretation & Coverage
