The patent's scope is primarily defined by its claims, which elucidate the patent's protective boundaries. As of the latest available data, the patent covers a pharmaceutical compound or composition with specific structural features or therapeutic indications—details reflect the invention's novelty and inventive step.
The patent's lifespan is 20 years from the filing date, which corresponds roughly to a filing date of 2004–2005. The patent was granted in Japan and potentially has family members in other jurisdictions, subject to national filings.
What are the key claims of JP5308486?
The claims section defines the patent's legal scope, including independent claims describing core inventions and dependent claims adding specific limitations.
Typical claim structure:
- Independent claims: Cover the core invention—such as a novel compound or formulation.
- Dependent claims: Cover specific embodiments, modifications, or use cases.
Example of likely claims based on Japanese patent standards:
- Claim 1: A chemical compound with a specific structure (e.g., a heterocyclic molecule), formulated for therapeutic use.
- Claim 2: The compound of claim 1, wherein the compound is in a particular salt form.
- Claim 3: A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
- Claim 4: Use of the compound in treating a specified disease (e.g., depression, cancer).
Claims are often centered around a novel chemical structure, methods of preparation, or therapeutic application.
Claim scope considerations:
- The claims emphasize structural novelty or unique synthesis methods.
- Limiting features include specific substitutions, stereochemistry, or pharmaceutical forms.
- Broad claims cover general chemical classes, whereas narrow claims specify particular derivatives.
