Patent Overview
Patent KR101716215B1, filed and granted in South Korea, covers a novel pharmaceutical compound or formulation. It primarily claims a specific chemical structure, its derivatives, and methods of preparation or use. The patent's scope appears focused on a particular class of compounds with potential therapeutic applications, possibly targeting cancer, infectious diseases, or inflammatory conditions, consistent with trends in recent filings. Key claims encompass both the compound itself and its pharmaceutical compositions, indicating a broad protective scope aimed at preventing competitors from producing similar medications.
Claim Structure
Main Claims
The main claims define a chemical entity characterized by a core structure with specified substituents. The claims specify:
- A chemical backbone with variable groups.
- Substituents attached at defined positions.
- Pharmacologically active derivatives or salts.
- Methods of preparing the compound through specific chemical reactions.
Dependent Claims
Dependent claims narrow scope to specific variations, such as:
- Specific substituent groups (e.g., methyl, ethyl, halogens).
- Particular stereochemistry configurations.
- Specific formulations or delivery mechanisms.
- Use in treating certain medical conditions.
Claim Breadth and Limitations
The broadness of the claims centers on the core chemical structure, with multiple dependent claims extending protection to derivatives. However, the scope is limited by the specificity of chemical groups and synthesis methods. Claims regarding methods and compositions extend protection but are often narrower since they relate to particular formulations.
Patent Landscape
filedate and lifecycle
- Filing Date: Likely filed between 2014-2015, given the 2017 publication date.
