What is the scope of patent KR20180120798?
Patent KR20180120798 pertains to a pharmaceutical invention related to a specific composition or method, though exact details require examination of the patent document. Based on typical Korean patent structures, the scope likely covers:
- Active compounds, their derivatives, or formulations.
- Methods of manufacturing or use related to the drug.
- Combinations with other agents or specific delivery systems.
The scope is confined by the claims section, which delineates the intellectual property rights granted. In general, the scope centers around a specific chemical entity or method disclosed in the patent.
What are the primary claims of patent KR20180120798?
The patent contains multiple claims, with a focus on:
- Independent Claims: Likely specify the core compound, composition, or therapeutic method. These claims define the broadest exclusivity.
- Dependent Claims: Narrow versions including specific embodiments, such as particular salts, formulations, dosages, or administration routes.
Without visual access, typical claims fall into these categories:
| Claim Type |
Content |
Protection Scope |
| Independent |
Composition or method involving a specific active ingredient |
Broadest coverage protecting core invention |
| Dependent |
Specific formulations, dosages, or combinations |
Narrowed scope adding details |
The language likely emphasizes novelty over prior art, with claims focusing on unique chemical structures or methods not previously disclosed.
How does the patent landscape look for this area of drug?
Major players and prior patents in South Korea and globally:
- Similar patents exist in the same therapeutic class, focusing on the same or related chemical compounds.
- International Patent Families: The invention may be part of a broader family filing in places like China, Japan, and the US. Patent PCT applications might exist, extending protection.
- Previous Korean Patents (Korean Patent Database): Prior arts include similar compounds or methods; the patent office likely rejected or phased out overlapping claims.
Key aspects influencing landscape:
- Patent novelty based on unique chemical structure or utility.
- Inventive step relative to prior art.
