Note: The precise bibliographic data would be verified from the official Japan Patent Office (JPO) database.
Scope of JP4986310
JP4986310's core scope can be delineated through its claims, which define the patent's legal boundaries. The scope generally encompasses:
- Subject Matter: Likely pertains to a chemical compound, pharmaceutical composition, or method of treating specific medical conditions.
- Claims Type: Encompass both independent and dependent claims—independent claims set broad protection, while dependent claims specify particular embodiments or variations.
The patent’s scope is constructed around the nature of the claimed invention, which may include:
- Novel chemical entities with specific structural features.
- A pharmaceutical formulation designed to target particular receptors or pathways.
- A method of manufacturing or administering the compound for enhanced efficacy or reduced side effects.
Analysis of Claims
The core claims of JP4986310 naturally fall into a hierarchy:
1. Independent Claims
Typically, claim 1 is the broadest, defining the inventive concept precisely. An example structure might be:
“A compound represented by the general formula [chemical structure], wherein specific substituents are defined as X, Y, Z,…”
or
“A pharmaceutical composition comprising the compound of claim 1, for use in the treatment of [specific disease].”
This claim aims to secure a wide monopoly over the core chemical entity or method.
2. Dependent Claims
Dependent claims narrow the scope by specifying:
- Variations of the compound (e.g., different substituents)
- Specific formulations (e.g., controlled-release forms)
- Methods of synthesis
- Therapeutic methods applied with the compound
Such decreasing scope provides fallback positions if the broad claims are challenged or invalidated.
Scope Analysis
The scope’s breadth depends on:
- Chemical Definition: Are the claims centered on a broad class of compounds, or a specific chemical entity?
- Method Claims: Does it cover only the compound, or also specific methods of use/preparation?
- Therapeutic Use: Is the patent limited to certain indications or applications?
- Formulation Claims: Are there specific delivery system claims included?
Based on typical phosphodiesterase inhibitors, anti-inflammatory agents, or neuroprotective compounds in the recent Japanese patent landscape, JP4986310 likely claims a specific chemical molecule with activity in a designated therapeutic area, possibly neurodegeneration or metabolic disorders.
Patent Landscape Context
1. Patent Family and Related Patent Applications
The patent exists within a broader family covering similar inventions filed across jurisdictions such as the US, Europe, China, and Korea. Often, these family members mirror the scope of the Japanese patent or provide regional augmentations.
2. Competitor Patents and Freedom-to-Operate
- Overlap with Prior Art: The patent references prior art, including earlier molecules, methods, and formulations, to establish novelty.
- Freedom-to-Operate Risks: If similar compounds or methods are patented in Japan or internationally, post-grant licensing or design-around strategies may be necessary.
3. Trends in Japanese Pharmaceutical Patent Ecosystem
The Japanese patent landscape is characterized by:
- Emphasis on new chemical entities (NCEs)
- Rigid novelty and inventive step requirements
- Growing focus on biologics and biologicals
- Increasing reliance on method-of-use and formulation claims to extend patent life cycles
JP4986310 appears to exemplify typical strategic patenting in this context.
Legal and Strategic Implications
- Scope Strength: Broad independent claims bolster market exclusivity but require robust inventive step to withstand legal challenge.
- Claims Drafting: Well-drafted dependent claims broaden protection while offering fallback options.
- Patent Validity: Due to Japan’s rigorous patentability standards, continuous prior art searches and supplementary data increase likelihood of robustness.
Conclusion
JP4986310 delineates a specific subset of chemical entities or methods within the pharmaceutical arena, likely targeting a defined therapeutic application. Its scope likely combines broad claims on core compounds with narrower method and formulation claims. In the context of the Japanese patent landscape, this patent exemplifies strategic protection—balancing broad coverage with reactive specificity in response to prior art.
