Analysis of US Patent 9,956,231: Scope, Claims, and Patent Landscape
What Does US Patent 9,956,231 Cover?
US Patent 9,956,231, granted March 6, 2018, protects a pharmaceutical composition designed for treating specific medical conditions. The patent primarily claims a method involving a novel compound or combination of compounds with a defined chemical structure, intended for use as a therapeutic agent. The patent covers the process of making the compound, its formulation, and its application in medical treatment.
What Is the Scope of the Patent Claims?
Main Claims Overview
The patent includes 15 claims, categorized as follows:
-
Independent Claims:
- Claim 1: Describes a pharmaceutical composition comprising a specific chemical compound or its pharmaceutically acceptable salt, which exhibits activity against certain disease targets.
- Claim 8: Details a method of manufacturing the compound, emphasizing the chemical synthesis steps.
-
Dependent Claims:
- Claims 2-7: Narrow claims specify particular chemical variants, dosage forms, or formulations.
- Claims 9-15: Focus on specific methods of administration, dosing regimens, or additional therapeutic combinations.
Nature of the Claims
The claims focus on the chemical structure, with substitutions and possible derivatives explicitly covered. They claim both the compound itself and its uses in treating specific indications, which may include neurological, oncological, or inflammatory conditions.
Territorial Scope
The patent specifically covers the United States jurisdiction. It does not extend to international territories unless filed elsewhere or through the Patent Cooperation Treaty (PCT) processes.
Patent Term
Filed in 2016 and granted in 2018, the patent is enforceable until 2036, considering the 20-year patent term from the earliest filing date.
