Overview of U.S. Patent 7,682,633: Scope and Claims Analysis
U.S. Patent 7,682,633 (the ‘633 patent) was issued on March 30, 2010. It relates to a specific pharmaceutical formulation or method involving a therapeutic agent, typically a novel active compound or a novel method of treatment. The patent's scope revolves around claims designed to protect the composition, use, or manufacturing process involving the specified compound or method.
Scope of the Patent
The ‘633 patent's scope covers:
- Chemical Composition: The patent claims include specific chemical entities or classes of compounds, often with detailed structures or chemical modifications.
- Method of Use: Claims may specify therapeutic applications, such as treatment of particular diseases or conditions.
- Manufacturing Process: Claims can extend to methods for synthesizing the compounds or preparing pharmaceutical compositions.
- Formulation and Delivery: Claims may involve specific formulations, excipients, or delivery systems.
The patent claims are structured in a hierarchy—from broad independent claims covering the core invention to narrower dependent claims adding specific limitations.
Claims Breakdown
The patent generally comprises:
- Independent Claims: Cover the broadest scope, asserting rights over the chemical entity, use, or method without further limitations.
- Dependent Claims: Narrower claims that specify particular chemical structures, dosages, methods, or combinations.
Example of Claim Types in the ‘633 Patent:
- Composition claims defining the chemical structure of the active ingredient.
- Method claims asserting the therapeutic use of the compound in treating specific diseases (e.g., cancer, inflammation).
- Process claims involving synthesis steps or formulation techniques.
Novelty and Inventiveness
The claims focus on differentiating the patented compounds or methods from prior art by specific structural features, purification methods, or therapeutic results. The patent references prior art references to establish novelty, including earlier patents and scientific publications.
Key points include:
- Structural modifications that improve stability, bioavailability, or target specificity.
- Use of specific delivery vehicles or excipients.
- Demonstration of unexpected therapeutic effects not disclosed in prior art.
Scope Limitations
The breadth of claims is constrained by prior art challenges. Patent examiners enforce novelty and non-obviousness, usually resulting in claims that are narrower than initially desired by applicants.
Examples of claims limitations include:
- Specific substitutions on the core chemical structure.
- Defined dosage ranges.
- Use in particular patient populations.
The claims’ scope can also be influenced by:
- Patent prosecution history, including amendments and office actions.
- Jurisdictional considerations—similar patents in other countries may have different claims scope.
