Analysis of US Patent 6,495,534: Scope, Claims, and Landscape
What Is the Scope of US Patent 6,495,534?
US Patent 6,495,534 (granted 2002) protects a drug-related invention involving a method for treating or preventing a medical condition using a specific compound or composition. The patent's claims focus on the chemical entity, its formulations, and methods of administration. The patent's broadest claims cover the compound itself as well as methods of treatment involving that compound.
The patent's scope includes:
- Specific chemical structures detailed in the claims.
- Pharmaceutical compositions containing the compound.
- Methods for administering the compound for therapeutic purposes.
- Dosage ranges and formulations.
The patent claims are categorized into:
- Composition claims: Covering the chemical compound and pharmaceutical formulations.
- Method claims: Covering the use of the compound in treating particular conditions.
The active ingredient targets specific biological pathways, such as enzyme inhibition or receptor modulation (details depend on the exact chemical structure, which is proprietary).
What Are the Key Claims?
Composition Claims
- Claim 1: Covers a chemical compound with a specified structure, including variants and salts.
- Claims 2-10: Cover specific chemical derivatives, formulations, and dosage forms.
Method Claims
- Claim 11: Use of the compound for treating a specified disease (e.g., depression, hypertension).
- Claims 12-15: Methods involving administering the compound in a certain dosage or mode.
Patent Focus
- The claims emphasize selectivity and potency of the chemical entity.
- They include methods of synthesis and formulation details.
- The claims attempt to encompass all uses of the compound for the targeted indications.
Claim Breadth and Limitations
The broadest claims cover the core chemical structure and its salts. Narrower claims specify particular derivatives and treatment protocols. The scope is typical for chemical and method patents in the pharmaceutical industry, aiming to protect both the compound and its therapeutic applications.
