What is the scope of patent KR101579701?
KR101579701, filed in South Korea, relates to a pharmaceutical compound or formulation. The patent aims to protect specific chemical entities, compositions, or methods associated with a drug candidate. It primarily covers a particular class of compounds with claimed therapeutic effects, as well as their manufacturing processes.
The patent's scope includes:
- Chemical structures identified by detailed formulas.
- Uses of these compounds for specific medical indications.
- Formulations combining the active compounds with excipients or carriers.
- Methodologies for synthesizing the compounds.
This scope targets both the active molecules and their pharmaceutical application, with claims extending to formulations and synthesis methods.
What are the key claims of KR101579701?
The patent contains multiple claims structured into independent and dependent claims. The core claims delineate the proprietary chemical class and specific compounds.
Independent Claims
- Chemical Compound: Claims specify a chemical formula with defined substituents, positioning the molecule within a particular class (e.g., substituted pyrimidines, benzothiazoles, etc.).
- Medical Use: Claims cover the use of the compounds for treating diseases such as cancer, neurodegenerative disorders, or metabolic conditions.
- Preparation Method: Claims describe a process for synthesizing the compound, highlighting particular reaction steps or intermediates.
Dependent Claims
- Variations in substitution patterns on core structures.
- Specific stereochemistry arrangements.
- Different formulations or delivery systems (oral, injectable).
- Specific dosage regimes.
Claim Scope Limitations
- The chemical scope is restricted to certain substituents and molecular configurations.
- Use claims are limited to particular therapeutic indications, often with generic language like "for treating [disease]."
- Process claims are confined to certain synthetic routes.
