Scope of the Patent
Main Focus of the Invention
The core of JP5453559 centers on a novel chemical compound or a novel combination of known compounds, designed to enhance therapeutic efficacy, improve pharmacokinetics, or reduce adverse effects compared to prior art. Alternatively, it may concern a specific formulation or administration method.
Claim Types
- Independent claims: Likely span the chemical structure of a novel compound or a broad composition encompassing various derivatives, emphasizing the core inventive step.
- Dependent claims: Narrow down the scope to specific substitutions, dosage forms, or methods of preparation, adding layers of protection and specificity.
Claim Language and Interpretation
In Japanese patents, claim language tends to be precise, often employing broad language to cover a range of embodiments while being sufficiently supported by the description. For JP5453559, the claims may include:
- Chemical structures with specific substituents; for example, a particular heterocycle substituted with functional groups enhancing bioavailability.
- Pharmaceutical compositions comprising the claimed compound, often in combination with excipients or carriers.
- Method of use claims for treating specific indications using the claimed compound.
Legal Scope
The scope is primarily governed by the language used in claims, supported by the detailed description, which defines the embodiments and scope of the invention. Japanese patent law emphasizes clarity and context, ensuring claims are supported and not overly broad.
Claims Analysis
Given the typical structure in pharmaceutical patents, the key points include:
1. Chemical Structure Claims
The patent likely claims a class of chemical compounds characterized by a core scaffold with specific substituents that confer desired therapeutic activity. The scope encompasses all derivatives falling within the defined chemical genus.
2. Composition Claims
Claims extending to pharmaceutical formulations, such as tablets, capsules, injections, or topical applications, containing the inventive compound at specific doses or in combination with other active agents.
3. Method of Treatment
Claims may specify a method of administering the compound to achieve therapeutic effects, such as alleviating symptoms of a particular disease (e.g., cancer, neurodegenerative diseases, infectious diseases).
4. Manufacturing Process
