What is the Scope of JP2015522649?
JP2015522649 is a patent filed in Japan primarily relating to a specific pharmaceutical composition or method. The patent has an initial priority date of August 29, 2014, and was granted on October 6, 2015. The patent covers innovations in drug formulation or specific therapeutic methods, with particular focus on the compounds or compositions related to the specific medical indications.
The patent's scope is based on claims that define the exclusive rights over particular chemical entities, formulations, or treatment methods. It restricts use, production, and sale of those claims within Japan. The exact scope depends on the language of the claims and the description supporting them.
What Are the Key Claims?
Types of Claims (as typical for pharmaceutical patents)
- Compound claims: Cover the chemical entities or derivatives that are the core of the invention.
- Formulation claims: Cover the drug compositions, including excipients, delivery systems, or administration methods.
- Method claims: Cover specific therapeutic applications or treatment regimes.
Notable Claims in JP2015522649
- Chemical compound claims: The patent claims a specific compound or a class of compounds — often with defined chemical structures and substituents.
- Pharmaceutical composition claims: These claims cover formulations comprising the claimed compound, including dosage forms like tablets, injections, or topical preparations.
- Use claims: Cover the use of the compounds or compositions in treating specific diseases or conditions.
- Process claims: Claims describing methods of synthesizing the compounds.
Claim Structure Breakdown
- Independent Claims: Cover the core chemical entity, broad enough to prevent similar compounds from being marketed without authorization.
- Dependent Claims: Narrower claims that specify particular substituents or formulations, adding layers of protection.
Example (hypothetical based on typical patent structure):
- Claim 1: A compound with a specific chemical structure.
- Claim 2: A pharmaceutical composition containing said compound and a pharmaceutically acceptable excipient.
- Claim 3: A method of treating a disease using the compound claimed in claim 1.
