Scope, Claims, and Patent Landscape for U.S. Patent 9,415,008
What Is the Scope of U.S. Patent 9,415,008?
U.S. Patent 9,415,008 covers a class of pharmaceutical compounds designed for specific therapeutic applications. It primarily claims the structural features of a novel chemical entity with potential use in treating certain medical conditions, with a focus on its method of synthesis and corresponding formulation methods.
The patent discloses a compound with a specific core structure, defined by a chemical formula, with various optional substituents that broaden the scope. It aims to protect not only the core compound but also its intermediates, methods of preparation, and pharmaceutical compositions.
The patent's scope extends to:
- The chemical compound's structure with enumerated substituents.
- Processes for synthesizing the compound.
- Pharmaceutical compositions incorporating the compound.
- Methods of using the compound in treating specific diseases.
Claims are drafted broadly, covering the compound itself, derivatives, and their use in therapeutic methods.
What Are the Main Claims of U.S. Patent 9,415,008?
Independent Claims:
-
Compound Claim: A chemical entity with a core structure defined by a specific formula (e.g., Formula I) with permissible substituents that provide structural variations. For example, the claim may define a specific heterocyclic core with substituted groups at designated positions.
-
Method of Synthesis: A process for preparing the compound, involving specific reaction steps, reagents, and conditions.
-
Therapeutic Use: A claim covering the use of the compound in methods to treat a set of medical conditions, potentially including pain, inflammation, or neurological disorders.
Dependent Claims:
- Variations on the core structure with different substituents.
- Specific salt or ester forms of the compound.
- Formulations with carriers or excipients.
- Additional methods involving combinations with other drugs.
Claim Breadth:
The claims limit their scope to compounds with particular substituents but include provisions for chemical modifications, thus enabling coverage over multiple derivatives within the disclosed core structure.
