Claims of JP6387486
Note: As the full claims are not publicly listed here, this analysis interprets typical patent claim structures based on available information.
1. Compound Claims
The patent likely claims a specific chemical compound or a class of compounds with unique structural features. These claims specify the molecular structure, substitutions, stereochemistry, and purity levels, aimed at differentiating over prior art.
Scope:
Narrow to the particular chemical structure claimed, which could be an inhibitor, receptor modulator, or other therapeutic agent.
Implication:
Protection is primarily granted over the specific chemical entity, preventing competitors from manufacturing or selling identical or similar compounds within Japan.
2. Method of Synthesis
Claims may cover a novel synthetic route to prepare the compound with improved efficiency, yield, or stereoselectivity.
Scope:
Limited to the specific process steps, catalysts, solvents, or conditions claimed.
Implication:
Competitors cannot commercially produce the compound using the claimed process without infringing.
3. Pharmaceutical Composition Claims
Claims relating to formulations comprising the compound, excipients, and carriers.
Scope:
Encompass, for example, tablets, capsules, or injectable formulations containing the compound in specific concentrations.
Implication:
Protects specific formulations, but often with limitations on the concentration ranges or excipient types.
4. Therapeutic Method Claims
Claims against particular methods of treatment using the compound or composition.
Scope:
May specify, for example, a method of reducing inflammation, treating a specific disease, or alleviating symptoms.
Implication:
Treatments utilizing the invention are protected, but such claims are often limited in Japan unless they meet specific criteria for medical use patents.
Claim Interpretation and Limitations
- Narrower Claims: Typically, compound claims are highly specific, limiting scope but strengthening enforceability.
- Broader Claims: Method and use claims may be broader but face challenges for patentability, especially regarding medical indications, due to strict Japanese patent law.
Patent Term and Exclusivity
Given its filing date (likely in 2019, considering the publication process), JP6387486 provides enforceable rights for 20 years from the filing date, subject to maintenance fees and patent term adjustments.
