What Is the Scope of Patent KR102239042?
Patent KR102239042 resides within South Korea's patent classification for pharmaceuticals, specifically targeting drug composition and method claims. This patent focuses on a novel chemical entity or formulation with potential therapeutic application, most likely in oncology, immunology, or metabolic disorders, based on current patent filing trends.
The patent claims a compound, combination, or method that exhibits specific biological activity, stability, or delivery efficiency, with claims extending to:
- Chemical composition: Novel chemical structures or derivatives.
- Method of use: Therapeutic methods applying the compound.
- Formulation: Specific pharmaceutical formulations or delivery systems.
The patent does not encompass broad subclasses of drugs but targets specific molecules with detailed structural features. Its scope potentially overlaps with existing patents in similar classes but emphasizes unique substitutions, stereochemistry, or formulations that confer superior efficacy or stability.
What Are the Claims of KR102239042?
The patent's claims are divided into independent and dependent types.
Independent Claims:
- Cover a specific chemical compound with defined molecular structure.
- Claim a method of treating a disease using the compound.
- Encompass pharmaceutical compositions containing the compound.
Dependent Claims:
- Specify particular substituents and stereochemistry within the chemical structure.
- Detail dosage forms, such as tablets, injections, or topical formulations.
- Describe specific therapeutic indications or combinations with other agents.
Sample Claim Elements:
- A chemical structure represented by a core scaffold with substitutions at defined positions.
- A method for treating a disease characterized by a particular biomarker.
- Use of the compound in combination with a standard therapy.
The claims aim to protect both the compound's composition and its use, with some claims extending to formulations or delivery systems optimized for stability or bioavailability.

FAQs
1. What strategic advantages does a narrow patent claim provide?
Narrow claims can be easier to defend and less likely to infringe existing patents, establishing a strong patent estate around a specific invention.
2. How does the patent landscape affect drug development?
A crowded landscape signals high innovation but also increases the risk of patent infringement, requiring careful freedom-to-operate analyses.
3. What is the significance of filing in multiple jurisdictions?
It extends legal protection, prevents patent "wrapping" in key markets, and supports global commercialization.
4. Can the patent be challenged after issuance?
Yes, through oppositions or patent invalidity proceedings, particularly if prior art emerges or the claims are overly narrow.
5. What should be considered when licensing this patent?
Patent strength, scope, remaining lifespan, and overlaps with competitor patents determine licensing value and licensing strategy.
