Patent Overview and Technical Field
Patent KR100956369 pertains to a novel pharmaceutical composition or compound aimed at addressing a particular medical condition or mechanism, likely within a well-established therapeutic class such as oncology, neurology, or metabolic disorders. The patent’s detailed description indicates an inventive step over prior art involving a specific chemical structure, formulation, or method of use.
The patent’s technical field aligns with modern drug development, potentially covering:
- A new chemical entity (NCE)
- A novel formulation or delivery system
- A method of treatment or prophylaxis
- A combination therapy involving known drugs
Scope and Claims Analysis
Principal Claims and Their Breadth
The core claims of KR100956369 typically focus on:
-
Chemical Composition/Structure: These often specify the molecular structure, including substituents and stereochemistry. The claim scope extends to derivatives within a certain structural class, establishing broad exclusivity over related compounds.
-
Method of Use: Claims may cover administering the compound for specific indications such as cancer, neurodegeneration, or metabolic conditions. Use claims enhance patent value by safeguarding therapeutic applications.
-
Method of Manufacturing: Claims could detail synthesis pathways, especially if they confer advantages like increased yield, purity, or stability.
-
Formulation Claims: If applicable, claims extend to formulations that optimize bioavailability, stability, or patient compliance.
Scope of Claims and Patent Coverage
- The independent claims primarily define the broadest scope, often covering the compound or method broadly within the structural or functional class.
- Dependent claims narrow the scope by specifying particular embodiments, such as specific derivatives, dosages, or implementation methods.
This claim structure balances broad protection with fallback positions in case of invalidity challenges.
