What Is the Scope of Patent JPWO2012153396?
JPWO2012153396 covers a specific pharmaceutical invention, with the scope defined primarily through its claims and detailed description. The patent was filed in Japan and later published internationally under the Patent Cooperation Treaty (PCT). Its scope encompasses a novel drug formulation, therapeutic method, or compound related to a certain medical indication.
The essential elements of this patent involve:
- The active ingredient(s) involved, which could refer to a specific chemical compound or a class of compounds.
- The method of administration or use, potentially targeting a particular disease or condition.
- The formulation or composition for delivering the active ingredient.
The scope is confined to the inventive features disclosed, excluding prior art. It aims to protect the innovation from infringement by competitors preparing similar drugs or formulations for the same therapeutic purpose.
What Are the Key Claims of JPWO2012153396?
The patent includes a set of claims that delineate its legal protection. Based on typical structure, the claims fall into two categories:
Independent Claims
-
Composition Claim: Defines a specific pharmaceutical composition with a unique combination of ingredients or a novel formulation.
-
Method of Use: Covers a method of treating, preventing, or diagnosing a condition using the claimed composition or active compound.
-
Compound or Process Claim: Describes a novel chemical entity, its preparation process, or a specific polymorph or salt.
Dependent Claims
- Add limitations to the independent claims, specifying aspects such as dosage forms, ratios, pharmaceutically acceptable carriers, or treatment protocols.
Example (Hypothetical, based on typical patents of this type):
-
Claim 1 (Composition): A pharmaceutical composition comprising a therapeutically effective amount of compound X and a carrier Y for use in treating disease Z.
-
Claim 2 (Use): A method of treating disease Z, comprising administering to a subject a therapeutically effective amount of compound X.
-
Claim 3 (Compound): A compound selected from the group consisting of salt forms, polymorphs, or derivatives of compound X.
The claims are likely narrow enough to protect specific features but broad enough to cover potential modifications, such as different salts or formulations.
Patent Landscape for Similar Inventions
Global Overview
The patent landscape surrounding JPWO2012153396 involves filing activity in multiple jurisdictions, notably:
- Japan: The original or priority filing country, with early priority dates.
