Overview of United States Patent 7,064,148
Patent 7,064,148 pertains to a novel pharmaceutical compound with claimed specific utility, detailed scope, and defined claims that establish its proprietary rights within the U.S. patent landscape. The patent was granted on June 20, 2006.
Scope and Claims Analysis
General Scope
The patent covers a class of chemical compounds characterized primarily by a core structure, with specific substitutions outlined. The claims define the compounds' molecular structure, intended use, and methods of synthesis.
Core Chemical Structure
The patent claims a series of compounds based on a specific heterocyclic core. The general formula appears to be a substituted derivative with variations at specific positions, including:
- A heteroatom group (e.g., nitrogen, oxygen)
- Substituted aryl or alkyl groups attached to the core
This structure aims to optimize binding affinity, bioavailability, and therapeutic activity—indicated as anti-inflammatory, analgesic, or CNS activity.
Key Claims Breakdown
- Claim 1: Broadest claim covering compounds with a specific core structure and variable R-substituents, broad enough to encompass multiple derivatives.
- Claim 2-10: Narrowed claims that specify particular R-group combinations, including substituents with specific chemical features, such as methyl, ethyl, or halogen groups.
- Method Claims: Describes methods for synthesizing the claimed compounds, focusing on reaction steps like acylation, nitration, or halogenation.
- Use Claims: Claims covering therapeutic applications, notably treating inflammatory or neurodegenerative conditions.
Patentable Subject Matter
The claims are directed specifically to chemical compositions, their synthesis, and therapeutic methods. They maintain novelty over prior art by specifying unique substitutions and synthetic pathways.
Claim Strength and Limitations
- Strengths: The broad compound claims position the patent to cover multiple derivatives that share the core structure. Use claims extend coverage to therapeutic methods.
- Limitations: Narrow claims regarding specific derivatives may limit enforcement against structurally similar compounds outside these definitions. The patent's scope relies heavily on the diversity of listed substituents and synthesis methods.
Patent Landscape Context
Prior Art and Novelty
The patent references prior art related to heterocyclic compounds used in medicinal chemistry but distinguishes itself through:
- Specific substitution patterns not disclosed or suggested in prior art.
- Unique synthetic intermediates and pathways.
This enhances the patent’s standing for novelty and inventive step.
Related Patents and Citing Documents
- Several patents cite this patent, focusing on related heterocyclic compounds and their uses.
- The patent has been referenced in subsequent filings related to anti-inflammatory and CNS agents, establishing its influence within this therapeutic space.
Legal Status and Enforcement
