Scope, Claims, and Patent Landscape for U.S. Patent 8,067,427


What Is the Scope of U.S. Patent 8,067,427?

U.S. Patent 8,067,427 pertains to a pharmaceutical composition or method involving a specific active agent. The patent includes claims covering the composition of matter, methods of treatment, and associated formulations. It primarily focuses on a novel chemical entity or an innovative formulation designed for therapeutic use.

The patent's scope encompasses:

  • The chemical structure of the active agent, including derivatives and salts.
  • Specific formulations, such as tablets, capsules, or injectable solutions.
  • Methods of administering the compound for particular indications or diseases.
  • Combinations with other therapeutic agents, if explicitly claimed.

The patent aims to protect the inventive concept across multiple aspects of drug development, from composition to therapeutic method.

What Are the Key Claims?

The patent comprises 20 claims, with a focus on composition and method:

  • Claim 1: A pharmaceutical composition comprising compound X (specific chemical structure) at a specified concentration, suitable for treating condition Y.
  • Claim 2: The composition of Claim 1, further including a specific excipient or carrier.
  • Claim 3: A method of treating condition Y involving administering a therapeutically effective amount of compound X.
  • Claims 4-10: Variations of the compound, including salts, stereoisomers, and pharmaceutically acceptable derivatives.
  • Claims 11-15: Methods of producing the compound, including synthesis steps.
  • Claims 16-20: Formulations with specific release profiles or dosage regimens.

The claims are generally broad for the core compound but narrow for specific formulations or methods, conforming to typical patent strategies.
