Filing Date: It is necessary to verify the initial filing date from patent databases. (Assuming 2015 based on the publication number, which indicates publication in 2015).
Priority Data: Typically, Japanese patents double as national entries, often claiming priority from provisional filings or international applications under PCT.
Invention Focus: While detailed claim specifics require access to the full patent document, patents with such publication numbers generally relate to chemical compounds, derivatives, or formulations for treating particular diseases—commonly cancers, neurodegenerative disorders, or metabolic conditions.
Inventive Objective: The patent likely aims to protect a new compound or a pharmaceutical composition with improved efficacy, stability, or reduced side effects over prior art.
Scope and Claims Analysis
1. Core Claims
The core claims are fundamental to defining the patent's scope. They specify the invention’s boundaries, including chemical structures, compositions, methods of use, or manufacturing processes.
-
Chemical Structural Claims:
Often, these reveal the specific molecular framework protected. For example, the claim might encompass a class of compounds with certain core structures—say, a heterocyclic skeleton—with substitutions at specific positions.
-
Method-of-Use Claims:
These specify the therapeutic indications, e.g., methods for treating particular diseases using the compound.
-
Formulation and Composition Claims:
Claims may cover pharmaceutical formulations, including excipients, delivery vehicles, or dosage forms.
2. Dependent Claims
Dependent claims refine the independent claims by adding limitations—specific substitutions, stereochemistry, or formulation features—thus creating a patent landscape that balances breadth with enforceability.
3. Claim Language and Interpretation
- Breadth: Broad claims may cover numerous analogs, giving substantial freedom to operate.
- Specificity: Narrow claims limit scope but provide stronger enforceability.
- Strategy: Patent applicants normally balance breadth and depth to prevent easy design-arounds.
4. Potential Claim Scope
Based on typical patents of this nature filed in Japan, JP2015517382 likely claims:
- A chemical compound with a specific core structure and variable substituents.
- An intermediate or derivative used in synthesis.
- A pharmaceutical composition comprising the compound.
- A method of treatment or prophylaxis for a specific disease using the compound.
