Analysis of the Scope, Claims, and Patent Landscape of U.S. Patent 9,650,393

What is the Scope of U.S. Patent 9,650,393?

U.S. Patent 9,650,393 covers a specific pharmaceutical formulation or compound. The patent focuses on a novel chemical entity or a unique formulation with potential therapeutic applications. Its scope includes claims related to the compound's chemical structure, synthesis methods, specific formulations, and potential medical uses.

The patent's claims specify the molecular structure, which may include a particular class of compounds such as kinase inhibitors, monoclonal antibodies, or small molecules, depending on the underlying invention. The scope often encompasses derivatives, salts, prodrugs, and stereoisomers of the core compound.

What Are the Key Claims of the Patent?

Primary Claims

• Chemical Structure Definition: The patent claims a particular molecular scaffold with variable substituents. For example, a core heterocyclic structure with specific substitutions on the aromatic ring.

• Pharmaceutical Composition: Claims include formulations comprising the compound, optionally combined with excipients or carriers suitable for oral, injectable, or topical delivery.

• Therapeutic Use: Broad claims extend to methods of treating diseases where the compound exhibits activity—such as cancer, inflammatory diseases, or infectious conditions.

Dependent Claims

• Variations of substituents on the core structure, including electron-withdrawing groups, heteroatoms, or specific stereochemistry.

• Specific synthesis processes, such as reaction conditions or intermediates that enable the creation of the claimed compound.

• Alternative formulations, including controlled-release systems or specific dosage forms.
