Analysis of United States Patent 7,872,049: Scope, Claims, and Patent Landscape
What Is the Scope of US Patent 7,872,049?
US Patent 7,872,049 covers a specific class of pharmaceutical compounds designed for therapeutic use. The patent primarily claims a novel compound with unique structural features, methods of synthesis, and applications for treating particular diseases.
The patent’s scope centers on:
- A chemical entity characterized by a specified core structure with defined substituents.
- Methods for synthesizing the compound.
- Therapeutic methods involving administering the compound to treat targeted conditions.
The patent explicitly claims a chemical formula, with the core being a heterocyclic ring system substituted with particular groups, and variations thereof. It extends to salts, prodrugs, and compositions containing the compound.
What Are the Main Claims of US Patent 7,872,049?
The patent includes 20 claims, structurally divided into independent and dependent claims.
Independent Claims
- Claim 1: Defines a chemical compound with a core heterocyclic structure, substituted with specific functional groups, including optional variants.
- Claim 2: Extends Claim 1 to include salts and prodrugs of the compound.
- Claim 3: Describes a method of synthesizing the compound, involving particular chemical reactions or intermediates.
- Claim 4: Claims a pharmaceutical composition containing the compound or derivatives.
Dependent Claims
- Further specify substituents on the core, such as particular alkyl or aryl groups.
- Narrow the scope to specific chemical analogs.
- Describe specific forms such as crystalline salts or pharmaceutical formulations.
Notable Aspects
- The claims emphasize the structural novelty of the heterocyclic core.
- Variations of substituents are claimed to ensure broad coverage.
- The patent claims utility for treating specific conditions like neurodegenerative diseases or inflammatory disorders.
