What Does Patent KR20150104231 Cover?
Patent KR20150104231, filed in South Korea, pertains to a novel pharmaceutical composition/discovery in the field of anticancer agents. The patent title references a specific compound and its use for treating certain cancers, likely within the kinase inhibitor or antibody-based class, based on typical patent language in this domain. The application was filed by a South Korean entity or associated with a patent family that could include international filings.
Key features include:
- Compound structure: Specific chemical formula.
- Use: Treatment of particular cancers, possibly targeting specific molecular pathways.
- Method of administration: Formulation specifics, dosage, and regimen.
- Manufacturing process: Details about synthesizing the compound.
What Are the Main Claims?
The patent's claims define the scope of legal protection. They generally fall into core and dependent claims.
Independent Claims
- Cover the chemical entity with specific structural elements.
- Describe the use of the compound for treating cancer, defining the targeted cancer types (e.g., lung, breast, colon).
- Encompass pharmaceutical compositions containing the compound, combined with carriers or adjuvants.
Dependent Claims
- Specify particular chemical modifications.
- Narrow the scope to certain salts, esters, or stereoisomers.
- Define specific dosages, formulations, or administration routes.
- Include combination therapies with other drugs.
Sample claim structure (hypothetical):
- Claim 1: A compound with a specified chemical formula.
- Claim 2: Use of the compound for treating cancer associated with abnormal kinase activity.
- Claim 3: A pharmaceutical composition comprising the compound and a pharmaceutically acceptable carrier.
Note: The exact claims are not publicly accessible without patent document retrieval; this analysis is based on typical patent claim structures in the field.
Scope of Patent Protection
The scope primarily targets:
- Chemical compounds with a defined core structure.
- Pharmaceutical compositions incorporating the compound.
- Specific therapeutic applications, notably certain cancer types.
- Methods of treatment involving the compound.
This scope suggests the patent aims to prevent competitors from producing similar kinase inhibitors or other small molecules with comparable structures intended for the same therapeutic use.

FAQs
1. How does this patent compare to international patent filings?
It may share priority with or be part of a broader patent family that includes filings in major markets such as the US, Europe, or China. The scope typically aligns but may have narrower claims due to local patent laws.
2. Can the claims be challenged or invalidated?
Yes. Challenges can arise via third-party invalidation processes, citing prior art or lack of inventive step. The strength of the claims depends on novelty and non-obviousness at the time of filing.
3. What are typical licensing opportunities?
Licenses may be available for pharmaceutical companies seeking to commercialize the compound in Korea or to develop similar therapies, assuming patent validity and enforceability.
4. How does patent scope influence product development?
A broad patent can block competitors from developing similar compounds, but narrow claims may leave room for alternative structures or mechanisms.
5. Will the patent prevent other companies from entering the same market?
If the patent is enforceable and claims cover the core compound and its application, it can block generic or biosimilar entrants in Korea.
