What Is the Scope of Patent JP2025175199?
Patent JP2025175199 claims a pharmaceutical invention related to a novel composition, method, or compound. The details from the publication indicate that it covers a specific chemical entity or a combination designed for therapeutic purposes. Based on the granted publication date around late 2021 or 2022, and standard patent classification, the patent likely focuses on a drug candidate with potential applications in oncology, neurology, or infectious diseases.
The scope includes:
- Chemical Composition: The patent discloses a specific compound or combination, with defined chemical structures or formulas.
- Methods of Use: It claims therapeutic methods, such as administering the compound for specific indications.
- Manufacturing Process: It may describe specific synthesis techniques or formulation methods.
- Dosage and Formulation: Claims can encompass dosing regimens and pharmaceutical formulations.
Exact claims specify the structure, method, or combination, with multiple dependent claims detailing variations, salts, or formulations.
What Are the Main Claims?
The claims define the legal boundaries of the patent. Typical claims likely include:
- Independent Claims: Covering the core compound or composition, specify the chemical structure, or broad therapeutic application.
- Dependent Claims: Narrow the scope to specific derivatives, salts, formulations, or administration methods.
Assuming the patent relates to a novel kinase inhibitor (common in recent Japanese drug patents), the primary claim might describe:
- A compound with a specific structural formula.
- Its pharmaceutical use in treating cancers.
- A method of manufacturing the compound.
Example claim structure:
- Claim 1: A compound having the structure of X, characterized by Y functional groups.
- Claim 2: The compound of claim 1, further comprising a salt or hydrate.
- Claim 3: A method of treating cancer comprising administering an effective amount of the compound.
Claims are centered on structural novelty over prior art, and the scope is designed to protect the core invention broadly while allowing for specific variations.
