Publication Date: 2016 (per standard Japanese patent publication timelines).
Priority Date: Corresponds to date of initial application, critical for prior art considerations.
Scope of the Patent
Core Aspects Coverd
- The patent primarily claims novel chemical compounds, pharmaceutical compositions, and method of use for treating specific diseases, potentially spanning infectious diseases, oncology, or metabolic disorders.
- The scope likely encompasses structure-activity relationships, formulation innovations, and methodologies for administering the compounds.
Claims Overview
Japanese patents generally contain multiple elements: independent claims set the broadest protection, with dependent claims narrowing or specifying embodiments.
Independent Claims
- Chemical Entities: Usually define particular chemical structures through Markush formulas or specific substituents, e.g., “A compound of formula (I), wherein R1, R2, R3 are...”.
- Pharmaceutical Composition: Claims may extend to formulations comprising the compound(s), combined with excipients, carriers, or stabilizers.
- Methods of Treatment: Claims often cover administration of the compound or composition to treat diseases, possibly including dosage parameters or delivery routes.
Dependent Claims
- Narrow to specific substituents, stereochemistry, salts, derivatives, or formulations.
- Possibly specify use cases, such as treatment of certain cancer types, infectious agents, or metabolic pathways.
Claim Interpretation and Significance
- The broadest independent claims set the foundation for patent scope, providing protection against competitors developing similar compounds or treatment methods.
- Narrower dependent claims reinforce protection over specific embodiments, increasing patent robustness.
