Introduction
Patent KR20200141533 pertains to a novel pharmaceutical invention within South Korea's intellectual property framework. Analyzing its scope, claims, and the broader patent landscape provides critical insights into its strategic value and potential competitive positioning. This patent document reflects South Korea’s active engagement in drug innovation, especially within innovative therapeutics and molecular platforms.
Patent Overview and Background
KR20200141533 was published in 2020, with a priority date likely preceding this publication, possibly around 2019. While specifics depend on the actual patent document, typical patents in this domain cover novel drug compounds, formulations, or delivery methods. The patent’s technical scope appears to be centered around a specific pharmaceutical compound or a therapeutic method, aiming to address unmet medical needs within a targeted disease area.
Scope of the Patent
Scope refers to the extent of protection granted by the patent's claims and determines the boundaries within which third parties cannot operate without infringing. In this patent:
- The claims likely encompass novel chemical entities or compositions with specific pharmacological activities.
- The scope may include methods of synthesis, formulation strategies, or administration procedures, broadening protection.
- The claim language probably emphasizes structure-activity relationships (SAR), outline of key functional groups, or specific configurations that confer unique biological properties.
- Use claims may be present, claiming the application of the compound for treating specific diseases, such as cancers, autoimmune disorders, or infectious diseases.
Implications:
- Wide claims covering multiple chemical derivatives increase the patent’s defensive strength.
- Narrow claims focusing on a specific compound limit flexibility but strengthen enforceability.
Claims Analysis
Detailed claims analysis reveals how the patent stakes its legal rights:
-
Independent Claims:
Typically define the core invention, such as a chemical compound with a specified structure or a method of manufacturing. They generally specify key structural features, functional groups, or a combination of features that define novelty.
-
Dependent Claims:
Expand on the independent claims by adding specific embodiments, such as particular substituents, dosage forms, or treatment methods. They serve to strengthen the patent's scope by providing fallback positions if broader claims are invalidated.
-
Claim Language:
Precision in claim language is vital. Use of terms like “comprising,” “consisting of,” or “configured to” influences claim breadth:
- “Comprising” offers open-ended protection.
- “Consisting of” is more restrictive.
-
Novelty and Inventive Step:
- The claims most likely hinge on unique structural features or unexpected therapeutic effects.
- Prior art searches probably reveal similar compounds, but the patent’s claims emphasize distinguishing features.
-
Scope of Use Claims:
These are crucial for pharmaceuticals, claiming specific therapeutic indications, hence securing patent rights over methods of treatment.
Conclusion:
The claims appear designed to balance broad protection for core compounds with narrower fallback claims for specific embodiments, effectively covering both composition and use.

FAQs
1. What strategic advantages does KR20200141533 provide to its owner?
It secures exclusivity over specific therapeutic compounds or methods, enabling market differentiation, licensing opportunities, and potential licensing revenue within South Korea and possibly abroad through PCT pathways.
2. How does the scope of claims influence patent enforceability?
Broader claims offer extensive protection but risk invalidation if prior art reveals similar inventions. Narrower claims are easier to defend but limit the scope of protection.
3. In what ways does South Korea’s patent landscape impact drug development?
South Korea’s vigorous patenting activity fosters innovation, encourages investments in R&D, and influences strategic patent filing to secure exclusivity in a competitive biotech environment.
4. Can this patent prevent competitors from developing similar drugs?
Yes, if the claims are sufficiently broad and enforceable, they can restrict third-party development of similar compounds or methods within the patented scope.
5. What should innovators consider when navigating the patent landscape in South Korea?
They should conduct comprehensive prior art searches, ensure robust claim drafting, and align patent strategy with global filing plans for maximum market and legal protection.
