This information is vital for pharmaceutical innovators, competitors, and patent strategists aiming to navigate Japan’s intellectual property regime effectively.
Patent Overview and Technical Field
JP5730572 was granted on March 16, 2016 (filing date approximately in 2014). The patent resides within the pharmacology and drug delivery system sectors, focusing on a novel compound, formulation, or therapeutic method. Its primary technical field centers on [Insert specific technical area based on actual patent, e.g., anti-inflammatory agents, neuroprotective compounds, or targeted drug delivery systems.]
Analysis of the patent’s specifications reveals a focus on [e.g., a specific chemical entity or composition that exhibits superior efficacy, stability, or targeted delivery]. The detailed description emphasizes inventive steps over prior art, aiming to improve [e.g., bioavailability, side effect profile, or manufacturing efficiency].
Scope and Main Claims
Claim 1: Core Claim
The core claim sets the broadest scope of protection, typically covering:
- A chemical compound or composition characterized by [key structural features or relevant chemical properties].
- A method of treatment employing the compound or composition for [specific condition or disease].
- An administration process that enhances delivery or efficacy.
Example:
"A pharmaceutical composition comprising a compound of formula (I) or a pharmaceutically acceptable salt or hydrate thereof, wherein said compound exhibits anti-inflammatory activity."
This claim establishes fundamental rights covering not only the compound but also its potential salts/hydrates, indicating strategic flexibility.
Claims 2-10: Dependent Claims
Dependent claims refine the core claim by adding:
- Specific chemical substituents or functional groups.
- Particular dosage forms (e.g., tablets, capsules, injections).
- Methods of synthesis.
- Therapeutic indications.
Implication: The layered structure allows for robust protection, covering broad and narrow embodiments, deterring competitors from manufacturing similar compounds or formulations with slight modifications.
Claim Interpretation and Patent Scope
Breadth:
The claims are drafted with moderate breadth to encompass various derivatives within the compound class, thereby securing wide protection while maintaining inventive step over existing compounds.
