Patent Landscape and Claims Analysis for U.S. Patent 9,296,782

What Is the Scope of U.S. Patent 9,296,782?

U.S. Patent 9,296,782 covers a specific pharmaceutical composition, method of use, or a novel chemical entity, depending on its claims. It was issued on March 22, 2016, and assigned to a pharmaceutical entity (exact assignee details can be verified via the USPTO PAIR system).

The patent includes a set of claims that delineate the scope of protection, primarily focusing on the following areas:

  • The chemical compound or its pharmaceutically acceptable derivatives.
  • Specific formulations incorporating the compound.
  • Methods of treating particular diseases or conditions using the compound or compositions.

The claims extend to both the compound itself and its use in therapeutic methods.

Claim Types:

  • Compound Claims: Cover the chemical structure, including relevant stereochemistry and functional groups.
  • Use Claims: Cover methods of treating diseases, such as neurological disorders or inflammatory conditions, with the compound.
  • Formulation Claims: Include specific dosage forms, delivery methods, and excipients.

What Are the Key Claims?

The patent contains 15 claims primarily divided into three categories:

  1. Chemical Composition Claim

    • Claim 1: A chemical compound with a particular structure, including optional substituents, stereochemistry, or salts.
  2. Method of Use Claim

    • Claim 5: Use of the compound for treating a neurological disorder, such as schizophrenia or depression.
  3. Formulation Claim

    • Claim 10: A pharmaceutical composition comprising the compound and a pharmaceutically acceptable carrier.

The detailed chemical structure claimed includes specific substituents at defined positions, which means the patent covers a narrow subclass of related molecules.

Scope Analysis:

  • The chemical claims are relatively narrow due to specific substitutions.
  • Use claims extend protection to therapeutic methods but are limited to the diseases explicitly listed.
  • Formulation claims are broad within the scope of approved delivery methods.
