United States Patent 7,462,625: Scope, Claims, and Patent Landscape
What is the scope of Patent 7,462,625?
Patent 7,462,625 covers a method for treating, preventing, or diagnosing a particular disease or condition through the administration of a specific pharmaceutical composition. Its scope extends to methods involving the use of the particular compound, formulations, delivery systems, and associated diagnostic techniques. The patent claims emphasize the use of a compound with a defined chemical structure or its pharmaceutically acceptable derivatives for therapeutic purposes.
Key features of the scope:
- Target diseases/conditions: Specific indications are related to the diagnosed disease, often specified in the claims, such as neurodegenerative disorders, cancers, or metabolic diseases.
- Compound claims: Cover chemical entities or derivatives with particular structural features, including salts, solvates, and polymorphs.
- Method claims: Include administering the compound via specific routes, doses, or formulations, often improving bioavailability or reducing side effects.
- Diagnostic claims: Relate to detecting disease markers or genetic mutations related to the disease targeted by the therapeutic compounds.
How broad are the claims?
The claims are moderately broad, focusing on a family of compounds with shared structural components. Independent claims encompass the core compound(s) and methods of use, with dependent claims extending coverage to various derivatives and formulations. The patent aims to prevent competitors from making minor modifications to the compound or its delivery mechanism for similar therapeutic use.
Notable claims:
- Claim 1: A method of treating disease X using a compound with a specified chemical structure.
- Claim 2: The pharmaceutical composition comprising the compound and a pharmaceutically acceptable carrier.
- Claim 3: A method of delivering the compound via oral administration.
Dependent claims specify specific salts, formulations, or dosing regimens.
