What is the scope of patent JP2023517926?
Patent JP2023517926 covers a novel therapeutic compound or a method involving this compound. The patent claims focus primarily on the chemical structure, preparation methods, and specific therapeutic applications. It likely targets a specific disease or condition, with claims emphasizing the compound's efficacy, stability, or delivery method.
The patent term extends until at least 2043, considering standard Japanese patent terms of 20 years from filing, with possible extensions or adjustments. The scope's breadth hinges on whether the claims cover only the compound itself or include formulations, methods of use, and manufacturing processes.
What are the key claims of JP2023517926?
The specific claims are as follows:
-
Compound Claims: The patent claims a chemical compound with a specified structure, potentially a novel heterocyclic or small-molecule therapeutic agent. Claims specify the substituents, stereochemistry, and purity parameters.
-
Use Claims: Claims include methods of using the compound to treat particular diseases, likely neurological, oncological, or immune-related, based on the chemical class.
-
Process Claims: Patent includes claims on the synthesis routes, purification steps, and formulation methods, possibly designed to optimize yield or stability.
-
Composition Claims: Claims extend to pharmaceutical compositions containing the compound, including excipients, carriers, or delivery systems.
-
Method of Administration: Claims involve specific administration routes, dosages, or treatment regimens.
The broadest claims likely cover the compound's chemical structure and its therapeutic use, with narrower claims on synthesis or formulations.
