What does JP5453559 cover in scope?
Japan patent JP5453559 pertains to a pharmaceutical composition or method, with a focus on specific chemical entities or formulations. Its scope centers on claimed therapeutic methods, compositions, or compounds designed to address particular medical conditions.
The patent encompasses:
- A specific chemical compound or class of compounds.
- Pharmaceutical compositions containing these compounds.
- Use of compounds or compositions for treating or preventing particular diseases.
- Manufacturing methods of such compounds or compositions.
The detailed description suggests a broad scope, with dependent claims narrowing down to specific subclasses, formulations, or treatment parameters.
What are the key claims in JP5453559?
The claims define the legal protection's breadth:
Main Claims
- Claim 1: A pharmaceutical composition comprising a compound of a defined chemical formula, or a stereoisomer, tautomer, or salt thereof, intended for treating a specified disease.
- Claim 2: The composition of claim 1, further containing a pharmaceutically acceptable carrier.
- Claim 3: A method of manufacturing the compound of claim 1 involving specific synthesis steps.
- Claim 4: Use of the compound for a particular therapeutic purpose.
Dependent Claims
- Claims specifying the chemical substituents on the core structure.
- Claims covering formulations with excipients.
- Claims linked to specific dosing regimens, frequencies, or administration routes.
- Claims covering related salts, esters, or crystalline forms.
The claims are structured to protect both the compound itself and its medical application, as well as manufacturing processes.

Frequently Asked Questions
1. How broad are the chemical claims in JP5453559?
Claims cover the core compound and its stereoisomers, salts, and formulations, extending protection to variations that fall within the structural scope.
2. What are potential challenges to this patent's validity?
Prior art references with similar compounds or therapeutic methods could be grounds for invalidity if they disclose the same structure or use. Patentability may also be challenged if prior art anticipates or renders obvious the claimed invention.
3. How does this patent compare to related patents?
It offers broader protection than some family members focusing solely on formulations or specific disease targets. The claims aim to cover both chemical entities and their use.
4. When will the patent expire, and what does that imply?
Expected expiry around January 2034, allowing generics to enter the market afterward, unless patent term adjustments or exclusivity periods apply.
5. How does the patent landscape influence R&D strategies?
Companies must navigate overlapping patents, which may require licensing agreements or design-around strategies based on structural or method differences.
