Scope and Claims Analysis
Claims Overview
The core of JP7393485’s protection resides in its claims, which define the patent’s territorial scope and enforceable rights.
-
Independent Claims:
These typically specify the compound, formulation, or method of use that constitutes the invention’s core. For JP7393485, the claims likely focus on a novel chemical entity, a specific dosage form, or a therapeutic method involving the compound. For example, an independent claim might define a compound with a particular chemical structure, coded in chemical formula terms, combined with specific substituents that confer unique functional characteristics.
-
Dependent Claims:
These narrow the scope, adding specific features such as salt forms, prodrugs, formulations with excipients, or specific methods of synthesis. Dependent claims also often specify therapeutic indications, such as treatment of a particular disease or condition.
Scope of the Claims
The scope of JP7393485 appears centered on:
-
Chemical Structure:
A novel heterocyclic compound or a subclass thereof. The claims might specify particular substitutions on a core ring system, conferring enhanced efficacy, stability, or bioavailability.
-
Therapeutic Use:
It may claim use in the treatment of specific diseases such as cancer, neurodegenerative disorders, or infectious diseases. The claims may cover not only the compound itself but also methods of administering the compound to a patient to treat certain conditions.
-
Formulations and Delivery:
Claims could encompass specific formulations (e.g., sustained-release, targeted delivery) or combinations with other active ingredients, broadening the protective scope into formulations and methods.
Key Elements of the Claims
