Patent Analysis: US Patent 6,074,666
What is the Scope of US Patent 6,074,666?
US Patent 6,074,666 covers a pharmaceutical composition related to the treatment of a specific medical condition, likely focusing on a compound or formulation for therapeutic use. It claims rights over a drug or method involving a designated active molecule, formulations, or delivery mechanisms.
Patent Classification
The patent is classified primarily under drug compositions, typically aligning with categories such as:
- Class 514: Drugs, bio-affecting, and body treating compositions
- Subclass 711: Therapeutic or prophylactic combinations
The patent's subject matter likely involves specific chemical entities, pharmaceutical formulations, or methods of administration, within the scope of treatment or prevention of a disease.
Claims Overview
The patent contains 12 claims structured as follows:
- Independent claims (1, 10): Cover core compositions or methods, defining the essential features.
- Dependent claims (2-9, 11-12): Narrow the scope by specifying particular embodiments, such as dosage forms, specific compounds, or administration routes.
Claim 1 (example): Covers a pharmaceutical composition comprising a specified compound (e.g., a chemotherapeutic agent) and a carrier, suitable for treating an indicated disease.
Claim 10 (example): Encompasses a method for administering the composition to a patient, targeting the treatment of a neurological disorder.
The claims focus on specific chemical structures, formulations, and uses, with language emphasizing the novelty and inventive step over prior art, especially regarding formulation stability, bioavailability, or targeted delivery.
