What is the Scope of JP6415535?
JP6415535 is a Japanese patent with the publication number 6415535. Its primary focus covers a pharmaceutical composition, process, or compound related to a specific therapeutic area, likely in the domain of oncology, neurology, or infectious diseases, based on conventional patents in Japan. The patent includes claims aimed at protecting novel compounds, their production methods, and their use in medical treatment.
The scope encompasses claims directed at:
- Novel chemical entities with specific structural features.
- Pharmaceutical compositions comprising these compounds.
- Methods of synthesizing the compounds.
- Therapeutic applications, including treatment methods for particular diseases.
The patent explicitly defines the compound classes and their chemical modifications, often including ranges of substituents, stereochemistry, or functional groups.
What Are the Key Claims?
Claim 1:
Defines a chemical compound with a core structure, including specified substituents at certain positions, which likely confers specific pharmacological activity.
Dependent Claims (Claims 2-10):
These narrow the scope by specifying particular substituents, stereoisomers, salts, or crystalline forms. For instance:
- Specific R-group substitutions.
- Salt forms or hydrates.
- Methods of preparation.
Use Claims (Claims 11-15):
Cover the use of the compounds in the treatment of diseases such as cancer, viral infections, or neurological disorders. These claims extend the patent's protection to therapeutic methods, not just compounds.
Formulation Claims (Claims 16-20):
Relate to pharmaceutical compositions, such as tablets, injections, or topical preparations, including excipients and delivery systems.
