Overview of JP2007516403
Filed in 2007, JP2007516403 was granted to document inventive progress in drug development, likely involving a specific chemical compound or therapeutic method. The patent's primary purpose is to secure exclusive rights for the claimed innovation within Japan's jurisdiction, preventing unauthorized manufacturing, usage, or sale.
Note: Precise details of the patent's technical content depend on the patent document's claims and description sections, which focus on chemical structures, pharmaceutical compositions, or manufacturing processes.
Scope of the Patent
The scope of a patent is primarily defined by its claims, which delineate the legal boundaries of the invention. For JP2007516403, the scope can be broadly grouped as follows:
- Device or Substance Claims: Covering specific chemical entities or their combinations.
- Method Claims: Covering specific therapeutic or manufacturing methods involving these compounds.
- Formulation and Composition Claims: Covering pharmaceutical formulations and formulations comprising the chemical entities.
Key Points:
- The claims potentially encompass a class of compounds with particular structural features.
- The patent may claim methods of treating specific diseases, particularly those responsive to the chemical entities or formulations disclosed.
- The claims likely include both broad and narrow language—broad claims cover general classes, while narrow claims focus on specific embodiments.
Claims Analysis
A typical patent like JP2007516403 includes multiple claims, often prioritized as independent or dependent.
1. Independent Claims
- Scope: Usually define the core inventive concept, such as a compound with a particular chemical structure, a method of treatment, or a specific pharmaceutical composition.
- Breadth: The broadest claims aim to encompass all compounds or methods within a class or genus.
2. Dependent Claims
- Scope: Narrower and refer back to independent claims.
- Purpose: Add specific limitations, such as particular substitutions, dosage regimens, or formulation features.
3. Chemical Formula Claims
- Likely detail the chemical structure with variable groups—‘R’ groups, substitutions, or stereochemical configurations—permitting coverage of multiple derivatives.
4. Method of Use Claims
- Cover specific therapeutic methods, possibly targeting conditions such as cancer, neurodegenerative diseases, or infectious diseases.
Implications for Stakeholders:
- The claims' scope determines the patent's strength and the possible defense against infringement.
- Broad claims offer extensive protection but may face validity challenges, especially if obviousness or lack of novelty is asserted.
- Narrow claims, while easier to defend, limit the scope of exclusivity.
Patent Landscape in Japan
1. Similar Patents and Family Members
- International Patent Family: JP2007516403 may be part of a broader patent family with counterparts in the US, Europe, and China.
- Related Patents: Previous applications or continuation patents might exist, extending patent rights or covering similar inventions.

- Several companies or research institutions likely hold patents covering related compounds, therapeutic techniques, or alternative formulations.
- Japan’s strong pharmaceutical R&D landscape ensures a competitive patent environment.
3. Patent Quality and Patentability Criteria
- To maintain enforceability, the patent must demonstrate novelty, inventive step, and industrial applicability within Japan.
- The claims' inventive step likely hinges on structural modifications, unexpected therapeutic benefits, or improved formulations.
4. Freedom-to-Operate (FTO) Considerations
- Stakeholders must assess whether existing patents in Japan, including JP2007516403 and related patents, could restrict commercialization.
- Due diligence involves reviewing prior patents, active applications, and patent applications in jurisdictions beyond Japan.
5. Patent Challenges and Oppositions
- Post-grant opposition procedures exist in Japan, where third parties can challenge patent validity during a specified window.
- The strength of JP2007516403 depends on prior art, novelty, and inventive step evaluations.
Legal and Commercial Implications

- Sufficiently broad claims can provide strong market exclusivity.
- Strategic claim drafting capable of covering various derivatives enhances patent value.
Potential Weaknesses
- Overly broad claims risk invalidation due to prior art.
- Narrow claims limit scope but provide stronger defensibility.
Operational Impact
- Patent holders can leverage this patent to safeguard exclusive rights in the Japanese market.
- Competitive entities must consider licensing or designing around strategies if overlapping claims exist.
Emerging Trends and Future Landscape
- The Japanese patent office (JPO) increasingly emphasizes thorough examination and patent quality, potentially affecting claims' scope.
- Advances in chemical synthesis and biotechnologies continuously influence patentability standards.
- Patent landscape analyses show a rising number of patents in targeted therapeutic areas, indicating active R&D.
