Japan Patent JP2018123151: Scope, Claims, and Patent Landscape

Last updated: February 28, 2026

What is the scope of JP2018123151 and what are its key claims?

JP2018123151 is a Japanese patent application related to a pharmaceutical invention. Its primary focus is on a specific compound or formulation, with claims outlining the scope of protection. The claims define the legal boundaries, specifying what constitutes infringement and what does not.

Main Claims Overview:

• Claim 1: Compound or composition
  Encompasses a specific chemical entity with defined structure, including derivatives or salts. It specifies the compound's purity, stability, or form factors.
• Claim 2: Pharmaceutical use
  Covers the application of the compound for treating a disease or condition, likely related to the therapeutic area disclosed in the application (e.g., cancer, neurodegeneration).
• Claim 3: Method of manufacture
  Details the process to synthesize or formulate the compound, emphasizing steps or conditions unique to this invention.
• Claim 4: Formulation or delivery system
  Includes formulations, such as tablets, injections, or topical applications, with particular excipients or delivery mechanisms.

Claim Scope Characteristics:

• The claims are drafted to cover the compound broadly, with specific derivatives or salts also included.
• Use claims are specific to therapeutic methods, emphasizing novelty in treatment application.
• Process claims focus on manufacturing innovations, possibly improving yield or purity.

Legal implications:

• The breadth of Claim 1 provides wide protection over the core compound.
• Dependent claims narrow down specific embodiments, providing fallback positions.
• The scope appears designed to prevent both direct and indirect infringement, covering composition, use, and method.

Patent Landscape Analysis
