What Is the Scope of Patent KR101446454?
Patent KR101446454 protects a pharmaceutical composition related to a specific therapeutic application. It specifically claims a formulation comprising an active pharmaceutical ingredient (API) combined with a suitable carrier for treating or preventing a particular disease.
The patent's scope covers:
- The composition's formulation details, including concentration ranges of the API.
- Specific methods of manufacturing the composition.
- Use of the composition for treating certain medical conditions.
The patent claims are structured to encompass both the composition and its medical use, enabling broad protection over the formulation and its application.
What Are the Key Claims of KR101446454?
The patent claims include:
- Composition claims: The composition contains a specified amount of API, which is a Novel compound or a known compound used in a novel way, combined with carriers suitable for pharmaceutical administration.
- Preparation method claims: Methods of manufacturing the composition involving specific steps such as mixing, granulation, or encapsulation.
- Use claims: The application of the composition to treat or prevent a defined disease, likely a chronic or degenerative condition based on the API's pharmacological profile.
Sample broad claim language often includes:
- "A pharmaceutical composition comprising [API] in an amount effective for treating [specific disease]."
- "A method of preparing a pharmaceutical composition, comprising mixing [API] with carriers under defined conditions."
- "Use of the composition for the manufacture of a medicament for treating [disease]."
The claims are designed to cover the API's formulation ranges, manufacturing steps, and therapeutic application.
