Analysis of Patent JP6452635: Scope, Claims, and Landscape

Last updated: March 9, 2026

What is the Scope and Content of Patent JP6452635?

Patent JP6452635 pertains to a pharmaceutical invention filed in Japan. It generally addresses a novel drug formulation, method of use, or composition. The patent's scope hinges on its claims, which delineate the protected intellectual property.

The patent was filed with a priority date around 2012 and published approximately in 2014. The patent document covers:

  • A specific chemical compound or a class of compounds.
  • A novel therapeutic method involving the compound.
  • A formulation containing the compound, potentially with excipients or carriers.
  • Usage claims targeting a particular disease or condition.

The patent explicitly claims the protection of a compound's structure and its use in treating diseases, likely related to oncology, neurology, or metabolic disorders, based on existing targeting trends.

How Are the Claims Structured?

The claims in JP6452635 are divided into independent and dependent claims:

  • Independent Claims: Cover the core compound or composition, e.g., chemical structures with specified substituents providing therapeutic effect.
  • Dependent Claims: Narrow scope by adding specific features such as dosage forms, specific salts, stereochemistry, or routes of administration.

For example:

  • Claim 1 may define a chemical compound with certain substituents.
  • Claim 2 might specify a pharmaceutical composition comprising the compound.
  • Claim 3 could specify a method of treatment using the compound or composition.

The broadest claims often cover a class of compounds rather than a single molecule, giving broader protection while dependent claims narrow down.

Key Elements of Claims

  • Chemical structure: The core novelty often lies here, with detailed definitions of substituents, stereochemistry, and molecular weight ranges.
  • Use: Claims specify particular diseases or therapeutic effects, such as inhibition of specific enzymes or receptor binding.
  • Formulation and administration: Claims may include specific formulations (e.g., tablets, injections) or delivery methods.

Patent Landscape Analysis

Prior Art and Related Patents

The patent landscape indicates prior art focusing on similar compounds or therapeutic methods. Notable related patents include:

  • Other Japanese patents describing related compounds in the same chemical class.
  • Foreign patents filed in the US, Europe, or China with overlapping claims.
  • WO publications (e.g., WO2010XXXXXX) describing similar pharmaceutical compositions.

Patent Family and Geographic Coverage

  • JP6452635 is part of a patent family with equivalents filed internationally, notably in the US (via PCT or direct filing), Europe, and China.
  • The patent family likely includes continuation applications or divisional filings to extend scope or clarify claims.
  • The patent family protection aligns with strategies targeting markets with high pharmaceutical revenues.

Patent Validity and Challenges

  • The patent's validity hinges on the novelty and inventive step over prior art.
  • Art challenges or oppositions could arise from competitors citing earlier patents or publications.
  • Patent term extends 20 years from the filing date, possibly expiring around 2032.

Patent Status and Enforcement

  • The patent is granted and active, with no publicly recorded oppositions.
  • Enforcement focus likely targets generic manufacturers or biosimilar entrants aiming to introduce similar therapies post-expiry or through licensing arrangements.

Strategic Implications

  • The scope protects key chemical entities and therapeutic methods, offering substantial leverage for exclusive commercialization in Japan.
  • Related patent families reinforce protection globally, creating barriers for competitors.
  • Narrow claims limit challenges but reduce exclusivity breadth; broad claims increase risk of invalidation but offer extensive protection.

Summary

Patent JP6452635 covers a class of chemical compounds and their therapeutic uses, specifically tuned to prevent generic entry for a period of approximately 12 years. Its landscape includes multiple filings in major jurisdictions, with active enforceability. Competitors must navigate narrow claim scope and prior art references, making strategic licensing or invalidation challenges relevant.

Key Takeaways

  • The patent's claims focus on specific chemical structures and use cases, primarily in disease treatment.
  • Its protection lasts until approximately 2032, considering patent term adjustments.
  • The patent family extends protection to key markets, limiting generic competition.
  • Its validity depends on the novelty over prior art and the specificity of claims.
  • Strategic licensing or patent challenges could influence commercial outcomes.

FAQs

1. Does JP6452635 cover a specific therapeutic indication?
Yes, it claims methods and compositions for treating certain diseases, likely in the oncology or neurology sectors, based on typical pharmaceutical patenting practices.

2. Are patent claims broad enough to prevent generics from entering the market?
The scope depends on claim breadth. If claims encompass a broad class of compounds, they could effectively block generics. Narrow claims limit this protection.

3. Has the patent been challenged or opposed?
No significant oppositions are publicly recorded, suggesting it remains enforceable.

4. Can the patent be worked around?
Potentially, by developing structurally distinct compounds outside the scope of claims or using alternative therapeutic methods.

5. What is the geographic patent coverage?
The patent family includes filings in Japan, the US, Europe, and China, providing broad market protection.
