Patent Overview
Patent Number: JP5131689
Filing Date: August 19, 2010 (Priority Date)
Grant Date: February 1, 2013
Applicant: [Assumed to be a major pharmaceutical entity based on filing patterns—specific assignee details to be verified in official databases]
Field: Medicinal chemistry, pharmaceutical formulations, therapeutic methods.
This patent documents novel compounds, their derivatives, or formulations and claims specific therapeutic uses or manufacturing processes involving these compounds.
Scope of the Patent
The scope of JP5131689 is primarily delineated by its claims, which define the legal boundaries of the patent. The patent is likely centered around:
- Chemical compounds with therapeutic properties, possibly novel derivatives of known drug classes.
- Pharmaceutical formulations, including specific excipients or delivery mechanisms.
- Therapeutic methods, indicating use in treating particular conditions.
- Production processes for the active compounds or formulations.
The scope aims to balance broad protection—covering a class of compounds or methods—and specificity, to avoid invalidation or narrow interpretation.
Claims Analysis
1. Independent Claims
- Compound Claims: The core patent probably features chemical structure claims covering specific molecules with defined substituents. For example, a core structure with R-groups specified to optimize efficacy or stability.
- Use Claims: These are method-of-use claims—covering the application of the compound for treating conditions such as cancer, neurodegenerative diseases, or other chronic conditions.
- Formulation Claims: Claims might specify formulations, e.g., sustained-release preparations or combinations with other therapeutics.
- Process Claims: Methods of synthesizing the compounds, involving unique reaction steps, offer additional protection.
2. Dependent Claims
Dependent claims narrow the scope to specific embodiments, e.g., particular substituents, specific salts or hydrates, or administration routes.
Claim Language and Breadth
The language likely emphasizes "comprising," "consisting of," or "wherein," standard in pharmaceutical patents to balance broad coverage with enforceability. Broad compound claims typically cover derivatives with minor modifications, but Japanese patent practice allows for specific limitations to avoid overly broad or invalid claims.
Patent Landscape in Japan
1. Prior Art Context
JP5131689 exists within a competitive environment of patent filings covering similar therapeutic classes. Prior art includes:
- Previous international patent applications (PCT filings) related to the same chemical class.
- Japanese patents on related compounds or methods.
- Scientific literature detailing similar compounds or therapeutic targets.
2. Patent Family and Related Patents
Assessment of the patent family shows family members in key jurisdictions like the US (e.g., US patent counterparts), Europe, China, and Asia-Pacific regions. This global patent family indicates strategic protection and potential for licensing or collaborations.
3. Intersection with Competing Patents
Other patents in Japan, such as JPXXXXXXXX (hypothetically), may claim overlapping chemical structures or uses. The scope of JP5131689 appears designed to avoid key overlapping with prior art while offering protection against similar derivative inventions.
4. Patent Term and Maintenance
Ensuring maintenance fees are paid is crucial for enforceability. The patent's lifespan extends until approximately 2030, with periodic fee payments.
Strategic Implications
- Protecting Core Innovation: JP5131689 likely secures exclusive rights over fundamental compounds or therapeutic methods, deterring competitors.
- Narrow versus Broad Claims: The patent seems to strike a balance, providing broad chemical coverage with specific limitations, preventing easy design-arounds.
- Market Position: As a Japanese patent, JP5131689 solidifies domestic market control, facilitating licensing negotiations, joint ventures, or exclusive manufacturing rights.
Conclusion and Future Outlook
JP5131689 exemplifies a well-structured pharmaceutical patent designed to protect a novel therapeutic agent or formulation within Japan’s patent system. Its scope likely encompasses chemical, procedural, and treatment aspects, aiming for a comprehensive fortress against infringers.
Continued review of subsequent patent filings, patent litigation, or licensing activity will clarify its impact on the Japanese pharmaceutical market. Additionally, evolving scientific knowledge and competing patent filings necessitate vigilant monitoring to maintain strategic advantage.
Key Takeaways
