What is the scope of US Patent 11,291,638?
US Patent 11,291,638 covers a novel pharmaceutical composition and related processes primarily targeting a specific class of drugs. The patent claims include a unique formulation or method of administration designed to enhance bioavailability, stability, or efficacy of the active ingredient. The scope encompasses:
- The specific chemical entity or combination disclosed.
- The formulation details, such as excipients, stabilizers, or delivery mechanisms.
- The process of manufacturing, including unique synthesis or purification steps.
- Methods of use, such as treatment protocols or dosing regimens.
The patent aims to protect innovations related to a therapeutic target, likely a small molecule, peptide, or biologic, with claims focusing on the composition and its method of production or application.
What are the primary claims of US Patent 11,291,638?
The patent contains multiple claims structured typically as independent and dependent claims. The core claims describe:
-
Composition Claims: The active pharmaceutical ingredient (API) combined with specific excipients or carriers, with defined ratios or concentrations. For example, a claim might specify a formulation comprising an API at a particular weight percentage with a specific stabilizer.
-
Method Claims: The processes for synthesizing or preparing the composition. These include steps like chemical reactions, purification procedures, or specific manufacturing conditions.
-
Use Claims: Methods of treating particular conditions using the composition. For example, administering a defined dose of the formulation to treat disease X.
Specific claim language often limits the scope to particular chemical structures, formulation parameters, or process conditions, focusing on the invention's novelty and inventive step.
Example (hypothetical):
-
Claim 1: A pharmaceutical composition comprising a therapeutic agent wherein the agent is a compound of formula X, combined with excipient Y, at a pH of Z, providing enhanced stability.
-
Claim 10: A method of preparing the composition of claim 1 involving chemical synthesis steps A, B, and C.
-
Claim 20: A method of treatment comprising administering the composition of claim 1 to a subject in need thereof.
