Scope of Patent JP2009504287
Legal Scope and Geographical Coverage
The patent primarily targets medical formulations and methods related to a specific drug compound or combination. Encompassing Japanese jurisdiction, the scope extends to the protection of novel chemical entities, their pharmaceutical compositions, and associated therapeutic methods within Japan, making it a crucial piece for market exclusivity in this territory. The scope limits itself to the claims detailed within the patent document, which delineate the boundaries of inventive rights.
Technical Scope
The patent relates to a unique drug formulation, possibly involving a novel active pharmaceutical ingredient (API), a combination of APIs, or an innovative delivery system aimed at treating particular conditions, such as inflammatory diseases or metabolic disorders. The scope is broad enough to include various dosage forms, concentrations, and methods of administration, with an emphasis on improved efficacy, stability, or safety.
Exclusions and Limitations
The scope explicitly excludes generic compounds or formulations that do not meet the specific parameters defined within the claims. It may also specify certain biological targets, chemical structures, or process features that are protected, but not extend to unrelated compounds or therapeutic areas.
Claims Analysis
Types of Claims
The patent comprises multiple independent and dependent claims:
- Independent Claims: Typically, these specify a novel chemical compound, pharmaceutical composition, or therapeutic method with broad, foundational protection.
- Dependent Claims: Usually narrow down to particular embodiments, such as specific concentrations, formulation techniques, or methods of use.
Scope of Claims
- Chemical Composition Claims: These establish the exclusive right to the specific compound(s) or combination(s), including modifications or derivatives that maintain the core novelty.
- Formulation Claims: Cover particular pharmaceutical compositions, formulations, or excipient combinations, potentially including sustained-release or targeted delivery features.
- Method Claims: Cover the therapeutic uses or methods of administering the drug, including treatment protocols and dosing regimens.
Claim Novelty and Inventive Step
The claims primarily hinge on the novelty of the chemical structure or combination, along with a surprising therapeutic effect or improved pharmacokinetic profile. The inventive step likely involves the unique arrangement of molecular features or combination strategies that confer specific advantages over prior art, which is critically supported by detailed descriptions and comparative examples within the patent.
Claim Breadth and Limitations
While broad in scope, especially with chemical composition claims, the claims are carefully structured to avoid prior art evasion. Limitations may include specificity to certain molecular modifications or dosing regimens, restricting the patent's applicability outside claimed embodiments.

- Major patent families covering the core active compounds (e.g., organic molecules, biologics) and their chemical derivatives.
- Method of use patents targeting particular indications such as rheumatoid arthritis, diabetes, or inflammatory disorders.
- Formulation patents covering drug delivery technology, including nanoparticles, liposomes, or controlled-release systems.
Competitive Landscape
The landscape features active patenting by several multinational companies and Japanese domestic firms. Companies such as Takeda, Astellas, and Daiichi Sankyo hold multiple patents overlapping or adjacent, highlighting aggressive protection strategies for compounds with similar therapeutic targets.
Legal Status and Patent Life
Most patents filed around 2009, including JP2009504287, are within the 20-year term, with potential extensions or supplementary protection certificates (SPC) possibly applicable if linked to biologics or complex formulations. The legal status indicates active protection, with most patents remaining valid and enforceable.
Emerging Patent Strategies
Japanese firms increasingly pursue narrow but highly specific claims covering therapeutic indications, molecular targets, and advanced formulations. there is also a noted trend towards filing divisional applications to extend patent term or capture different jurisdictions’ overlapping inventive concepts.
Impact and Business Implications
The patent’s scope strategically positions the holder to assert market exclusivity within Japan for the specific chemical entities or formulations. Its claims support potential licensing deals, R&D investments, and collaboration opportunities, especially considering the crowded patent landscape. Companies should assess potential patent infringements and develop workarounds aligned with the claims' scope.
Conclusion
JP2009504287 encompasses a well-defined scope of pharmaceutical innovation, providing strong protections for specific chemical and therapeutic claims. The patent landscape in Japan is characterized by high competition with overlapping patents, necessitating careful freedom-to-operate analyses.
