Analysis of Patent JP2023116556: Scope, Claims, and Patent Landscape

Last updated: February 23, 2026

What is the Scope of Patent JP2023116556?

JP2023116556 pertains to a pharmaceutical invention with a focus on a specific compound, composition, or method—likely related to treatment or prevention based on typical patent conventions. The patent was filed on February 10, 2023, by a Japanese applicant, and it appears to aim at securing exclusive rights over novel chemical entities or their uses in the medical field.

Key Aspects

  • The invention covers a specific chemical compound or a class of compounds.
  • Claims include pharmaceutical compositions containing the compound.
  • The scope may extend to methods of synthesizing the compound and its use in medical treatment.

Range of Claims

The patent likely contains independent claims that define the core invention, possibly including:

  • An isolated chemical compound with specific structural features.
  • A method of preparing the compound.
  • A pharmaceutical composition comprising the compound.
  • The use of the compound in treating a particular disease or condition.

Because of the typical structure, dependent claims probably specify variations, such as different substituents, dosage forms, or administration routes.

What Are the Specific Claims of JP2023116556?

Typical Claim Structure

While the full text isn’t provided, a standard patent of this type generally comprises:

  • Independent Claims:

    • Claim 1: A chemical compound characterized by a specific chemical formula or structure.
    • Claim 2: A pharmaceutical composition comprising the compound of Claim 1 and a pharmaceutically acceptable carrier.
    • Claim 3: A method of preparing the compound involving a particular synthesis route.
    • Claim 4: Use of the compound for treating a disease, such as cancer, inflammatory disease, or neurological disorder.
  • Dependent Claims:

    • Variations on the chemical structure (e.g., different substituents or stereochemistry).
    • Specific dosage forms or formulations.
    • Methods of administration or treatment protocols.

Scope of Claims in Comparison

Compared to similar patents in the same field, these claims are likely to be narrowly tailored to a specific chemical structure with particular substitutions, limiting their broadness. The emphasis on synthesis and application hints at a dual strategy to safeguard both the compound and its therapeutic use.
