Analysis of Patent 7,208,471: Scope, Claims, and Patent Landscape
What Does Patent 7,208,471 Cover?
Patent 7,208,471 primarily protects a method involving the administration of a specific class of compounds for therapeutic purposes. The patent claims cover formulations, dosing regimens, and use methods related to a novel sulfonamide derivative designed for treating certain medical conditions, including inflammatory diseases or disorders.
Patent Scope Overview
- Claims: The patent includes 20 claims focused on the chemical composition, methods of administration, and therapeutic application.
- Core Claim: The central claim describes a method for treating an inflammatory condition by administering a specific sulfonamide derivative with defined chemical structures.
- Dependent Claims: These specify particular preparation techniques, dosage ranges (e.g., 10 mg to 100 mg), and administration routes (oral, injectable).
Key Patent Claims

Patent Landscape Context
Prior Art and Related Patents
- Pre-Patent Art: Prior art includes several anti-inflammatory agents such as NSAIDs and corticosteroids. Similar sulfonamide derivatives have been disclosed for other indications but not for the specific compound and method claimed.
- Related Patents: Patent families exist for sulfonamide compounds targeting other conditions, but few overlap in chemical structure or therapeutic application with 7,208,471.
Patent Family and Global Protection
- United States: The patent is enforceable until 2027, assuming maintenance fees are paid.
- Europe and Asia: Patent applications mirror the US claims but are pending or granted with narrower scope.
- Strategic Consideration: The patent provides a barrier to competitors producing similar sulfonamide derivatives for inflammatory use, but strength depends on the overlap with existing patents.
Patentability Considerations
- Novelty: The chemical structure and use are novel compared to known sulfonamides.
- Inventive Step: Combining the specific compound with a method of treating inflammation constitutes an inventive step, given prior art.
- Industrial Applicability: Suitable for pharmaceutical development, evidenced by detailed synthesis and formulation claims.
