Scope and Claims Analysis of US Patent 11,241,391
What is the scope of US Patent 11,241,391?
US Patent 11,241,391 covers a novel formulation of a drug compound, primarily directed toward therapeutic applications. The patent aims to protect specific compositions, methods of manufacture, and methods of use related to a proprietary drug composition. It claims a combination of active ingredients, excipients, and specific dosages that optimize efficacy and stability.
The patent's scope includes:
- Fixed-dose combinations involving the primary active compound and an auxiliary agent.
- Novel methods of preparing the pharmaceutical composition, emphasizing specific manufacturing steps, such as microencapsulation or nanoparticle formulation.
- Method of use claims for treating particular indications, including, but not limited to, neurological disorders and metabolic conditions.
The patent explicitly excludes broader claims that could block generic entry, focusing on narrow, well-defined compositions and methods.
How broad are the claims of US Patent 11,241,391?
The core claims of the patent are narrowly drafted, targeting specific formulation details rather than broad classes of drugs.
Claims overview:
