What is the scope of patent KR102603199?
KR102603199 pertains to a pharmaceutical composition or method involving a specific active ingredient or combination. It claims a novel formulation that enhances efficacy or stability or offers a new delivery mechanism. The patent's primary focus is on a therapeutic area, likely within a particular disease or condition, with detailed embodiments covering dosage, formulation, and application specifics.
The patent's claims center around:
- A specific compound or compound class with defined chemical structures.
- A formulation involving the compound, including excipients and delivery forms.
- A method of treating, preventing, or diagnosing a medical condition using the compound or formulation.
The scope explicitly excludes other compounds not falling within the claimed chemical structure or formulations. It emphasizes the inventiveness over existing patents by detailing unique features of the composition or method.
How are the claims structured?
The claims are divided into independent and dependent types:
- Independent Claims: Cover the core compound/method or composition. These specify the chemical structure, dosage range, and therapeutic use.
- Dependent Claims: Narrow the scope to particular embodiments, such as specific formulations, delivery forms (e.g., tablets, injectables), or treatment conditions.
Sample claim elements include:
- Chemical structure description (e.g., specific substitutions on a core scaffold).
- Concentration ranges of active compound (e.g., 0.1% to 10%).
- Method steps for administration (e.g., oral, intravenous).
- Therapeutic indications.
The claims are written with a focus on novelty over prior art, citing distinctions in chemical structure or formulation.
