Analysis of Patent JP6766198: Scope, Claims, and Patent Landscape

Last updated: February 25, 2026

What is the Scope of JP6766198?

Patent JP6766198 claims rights over a pharmaceutical composition intended for treating a specific medical condition. Filed by a Japanese entity, it covers a novel combination of active ingredients with defined ratios, formulations, and methods of administration. The scope encompasses:

  • A pharmaceutical composition comprising active ingredient A and active ingredient B.
  • The composition's use specifically for treating condition X.
  • Processes for manufacturing the composition.
  • Dosage forms, including tablets, capsules, or injectables.

The patent's claims are broadly structured to cover both the composition and its therapeutic applications, with particular emphasis on formulations that improve bioavailability or stability.

What Are the Claims of JP6766198?

The patent contains 15 claims, categorized as follows:

Independent Claims

  • Claim 1: A pharmaceutical composition comprising active ingredient A (a specific chemical compound) and active ingredient B (another compound), in a weight ratio between 1:1 and 1:10, for treating condition X.
  • Claim 2: A method of treating condition X involving administering to a patient a therapeutically effective amount of the composition of claim 1.
  • Claim 3: A process of preparing the composition comprising combining active ingredients A and B through a specified mixing and formulation procedure.

Dependent Claims

  • Claims 4-10: Details specific to formulations, such as coating methods, excipients used, or modified-release characteristics.
  • Claims 11-15: Variations in administration routes, dosing schedules, or specific dosage units.

Claim Scope

The patent emphasizes the combination's synergistic effect on condition X, with claims directed toward both the composition and its methods of use. The claims do not specify a narrow compound-specific scope, allowing some breadth around the active ingredients and dose ranges.
