What Does U.S. Patent 9,205,056 Cover?
U.S. Patent 9,205,056, granted on December 8, 2015, extends the patent protection of a pharmaceutical compound or formulation. The patent primarily pertains to a novel chemical entity or a specific formulation thereof, with claims that define its scope.
Core Claim Types
-
Compound Claims: Cover the chemical structure of the active pharmaceutical ingredient (API). These claims specify the molecular formula, stereochemistry, and chemical modifications.
-
Method Claims: Cover methods of synthesizing the compound, as well as methods of using the compound for therapeutic purposes.
-
Formulation Claims: Cover specific compositions, including dosing forms such as tablets, capsules, or injectables containing the compound.
-
Use Claims: Cover the use of the compound for treating specific medical conditions, such as a particular disease or disorder.
Key Claim Elements
-
The core structure claimed resembles a specific chemical scaffold with defined substituents.
-
Several dependent claims specify possible variations of substituents, increasing patent scope flexibility.
-
Method claims specify dosage, administration route, and treatment indications.
-
Formulation claims include typical excipients and delivery systems.
Scope and Limitations
The patent’s scope revolves around a specific chemical entity, intended for treatment of designated diseases (likely neurological, psychiatric, or metabolic conditions based on structure), with claims covering the compound, its uses, and formulations.
-
Broadness: The compound claims are moderate in scope, limited to the core structure with permissible variations.
-
Narrower Claims: Use and formulation claims are more specific, focusing on particular applications and delivery methods.
-
