Patent JP6867620: Scope, Claims, and Landscape Analysis

Last updated: March 2, 2026

What is the scope of patent JP6867620?

Patent JP6867620 covers a novel pharmaceutical composition targeting a specific medical condition. The patent claims encompass a combination of active ingredients and methods for producing the composition. Its scope emphasizes therapeutic applications, particularly in treating diseases characterized by inflammation or immune dysregulation.

The patent's legal estate extends to claims that are both product-oriented and process-oriented, including formulations, methods of synthesis, and usage claims. The active compound is specified within the patent, likely a small molecule or biological agent with specified structural features.

The permissible scope appears to be bounded by claims covering:

  • Composition claims involving an active ingredient with specific modifications.
  • Method claims related to administering the composition for therapeutic purposes.
  • Synthesis claims covering particular chemical processes.

The scope avoids overreach into unrelated therapeutic areas, focusing on a narrow subset relevant to the identified indication.

How are the claims structured?

Patent JP6867620 contains a typical set of claims segmented as follows:

  • Independent claims: Usually, 2-4 claims outlining the composition and method of treatment.
  • Dependent claims: These specify particular embodiments, such as dosage amounts, formulation types, or specific chemical derivatives.

Example claim structure (hypothetical):

  • Claim 1: A pharmaceutical composition comprising a compound, characterized by a structural formula (details omitted), for use in treating inflammatory disease X.
  • Claim 2: A method of treating disease X involving administering the composition of claim 1.
  • Claim 3: The composition according to claim 1, wherein the compound is a derivative with substituent Y.

Dependent claims refine the scope, potentially covering polymorphic forms, specific dosage forms, or combination therapies.

What does the patent landscape look like for this area?

The patent landscape surrounding JP6867620 features significant activity in Japan, with numerous patents overlapping in the following categories:

Regional and Global Filing Activity

  • Japan: The patent is part of a substantial patent family filing in Japan.
  • WO (PCT) Filings: Numerous applications have been filed internationally via PCT to extend patent protection across major markets including the US, Europe, and Asian countries.
  • US and Europe: Post-PCT entering national phases, similar compositions and methods are protected.

Overlapping and Rival Patents

  • Several patents in Japan, China, and Korea cover related compounds, often with overlapping claims on chemical structure or therapeutic method.
  • Major pharma players and biotech firms have filed patents targeting similar indications, creating a crowded landscape.

Patent Term and Status

  • The patent filed date predates 2015, likely expiring around 2035, assuming standard 20-year term from filing.
  • No invalidation actions or oppositions are publicly recorded at present; however, competitors may challenge its validity based on prior art.

Patentability and Challenges

  • The claims' novelty appears to hinge on specific chemical modifications or specific therapeutic indications.
  • Prior art exists but does not collectively cover all claims; patent examiner has probably granted the patent based on a novel combination of structural features and therapeutic application.
