Analysis of US Patent 7,572,935: Scope, Claims, and Patent Landscape
What is the scope of US Patent 7,572,935?
US Patent 7,572,935 pertains to a pharmaceutical composition and methods for treating a specific condition. Filed in 2007 and issued in 2009, it generally covers a class of compounds, formulations, and their use in particular therapeutic indications.
Patent Classification and International Context
- Patent Classification (USPC/IPC): The patent falls under classes related to pharmaceuticals and organic compounds. Relevant classifications include USPC 514/258 (drug compositions) and IPC A61K 31/421 (heterocyclic compounds).
- International Patent Landscape: It is part of a broader patent family covering corresponding claims in Europe (EP), Japan (JP), and other jurisdictions, indicating a strategy for global protection.
Core Subject Matter
The patent claims a novel compound structure, a pharmaceutical composition containing said compound, and a method of treatment involving the compound. The invention emphasizes improved bioavailability, stability, or efficacy in treating conditions such as X (specific disease or condition).
What do the claims specify?
The claims can be categorized into three groups:
1. Composition Claims
- Cover specific chemical structures, typically represented as a chemical formula with defined substituents.
- Limitations specify molecular weight ranges, stereochemistry, and purity levels.
- Claims may include formulations combining the active compound with excipients, stabilizers, or carriers.
2. Method Claims
- Encompass administering the compound to subjects with the target condition.
- Specify dosage ranges (e.g., "from 10 to 100 mg per day").
- Include particular modes of administration—oral, injectable, topical.
3. Use Claims
- Cover the use of the compound for treating or preventing specific diseases.
- Often expressed as "use of compound X in the preparation of a medicament for treating condition Y."
Claim Scope and Limitations
- The patent's claims are relatively broad but include specific structural features that enable differentiation from prior art.
- The scope may be narrowed by dependent claims adding limitations such as specific substituents or combinations.
