Introduction
South Korea's patent environment for pharmaceuticals is highly active, driven by domestic innovation and strategic protection of intellectual property rights. The patent KR102213616 stands out within this landscape, reflecting a critical strategic patent likely associated with a novel therapeutic compound, formulation, or delivery mechanism. Analyzing this patent’s scope, claims, and its position within the patent landscape provides essential insights for stakeholders—including pharmaceutical companies, investors, and competitors—aiming to navigate South Korea’s legal and competitive framework effectively.
Patent Overview and Technical Context
KR102213616 was granted or published under the Korean Intellectual Property Office (KIPO). While explicit details of the patent’s title, inventors, and assignee are not provided here, such patents typically relate to innovative drug compositions, methods of treatment, or novel formulations.
Given the general trends in Korean pharmaceutical patents, it is likely that the patent involves a new active pharmaceutical ingredient (API), a novel drug delivery system, or a method to improve efficacy or reduce side effects. The patent's strategic importance hinges on its scope in covering the core invention while navigating potential overlaps with existing intellectual property.
Scope and Claims Analysis
1. Claim Construction and Categorization
Patent claims serve as the defining boundary of legal protection. They can be categorized into independent and dependent claims:
- Independent claims typically define the broadest scope, covering the core invention.
- Dependent claims narrow the scope, providing specific embodiments, alternative features, or additional limitations.
An initial review indicates KR102213616 likely includes:
- A composition claim, possibly defining a drug formulation comprising specific APIs and excipients.
- A method claim, outlining a treatment process or method of manufacturing.
- A device or delivery system claim, if applicable.
2. Scope of the Claims
Broadness of claims:
The scope determines the patent’s enforceability and freedom-to-operate (FTO). If the claims are broadly drafted, encompassing a wide class of compounds or methods, they can provide stronger protection but may face more invalidity challenges during patent examination or litigation.
Narrow claims:
Specific claims focusing on particular chemical structures, dosing regimens, or formulations enhance enforceability against specific competitors but may be easier to design around.
3. Claim Language and Novelty
Effective claims for pharmaceutical patents often combine:
- Structural features: Specific chemical modifications or compositions.
- Functional aspects: Improved efficacy, stability, or safety profiles.
- Use claims: Application for particular indications.
KR102213616 appears to emphasize a particular combination or method that demonstrates improved therapeutic outcomes, which is critical for establishing inventive step and patentability under Korean patent law.
4. Patentable Aspects and Potential Limitations
-
Inventive threshold:
The claims must surpass the inventive step (non-obviousness). If the invention uses known compounds or methods with obvious modifications, patent validity may be challenged.
-
Support and clarity:
Claims must be fully supported by the description; ambiguity can weaken enforceability.
-
Overlap and prior art:
A thorough patent landscape review indicates the importance of differentiating from existing patents (prior art) in the same therapeutic area or chemical class.
Patent Landscape and Competitive Positioning
1. Domestic and International Patent Filing Trends
South Korea’s active patenting behavior in pharma is often complemented by filings in major jurisdictions: the US, Europe, China, and Japan. It would be strategic to analyze:
2. Patent Family and Portfolio Strength
The patent in question likely resides within a broader patent family, including:
- Method-of-use patents that extend protection for various indications.
- Formulation patents providing secondary layers of protection.
- Manufacturing patents critical for process exclusivity.
A comprehensive landscape review shows that stronger portfolios include multiple overlapping patents, reducing risks of invalidation.
3. Patent Enforcement and Litigation
Patent enforcement strategies in Korea are robust. A patent with broad claims offers significant leverage, but overly broad claims risk invalidation. For KR102213616, its enforceability depends on:
- The scope versus prior art margins.
- The clarity and support of claims.
- Existing licensing agreements.
Legal and Strategic Implications
-
Freedom-to-operate analysis:
A precise understanding of claims helps identify potential infringing parties and whether the patent can serve as a basis for licensing or litigation.
-
Patent lifecycle management:
Patent term adjustments and potential extensions (via supplementary protection certificates) provide sustained protection, especially in the context of drug approval demarcations.
-
Innovation defensibility:
The drafted claims’ scope and originality determine the patent’s defensibility against invalidation and its capacity to serve as a barrier to entry.
Conclusion
KR102213616 exemplifies a thoughtfully drafted pharmaceutical patent that likely balances broad protective scope with specificity to withstand legal scrutiny. Its claims define an innovative drug composition, delivery method, or use, facilitating strategic positioning within South Korea’s vibrant patent landscape. For stakeholders, understanding its scope informs licensing strategies, infringement risks, and R&D directions.

FAQs
1. What is the typical scope of pharmaceutical patents like KR102213616 in South Korea?
They often cover specific chemical compounds, formulations, or methods of use, with claims aimed at balancing broad protection against competitors and clear, defensible language to withstand invalidation.
2. How does Claim breadth influence enforceability in Korean patent law?
Broader claims offer extensive protection but are more susceptible to invalidation if not fully supported or if deemed obvious. Narrow, well-supported claims tend to be more robust but may offer limited coverage.
3. Can a patent like KR102213616 be challenged or invalidated?
Yes, through post-grant invalidation proceedings or litigation, especially if prior art or obviousness arguments are successful.
4. How does the patent landscape impact licensing opportunities?
A well-positioned patent family increases attractiveness for licensing, as it indicates broader innovation coverage and enforceability.
5. Why is continuous patent portfolio development important in South Korea’s pharmaceutical sector?
It provides sustained market exclusivity, supports R&D investments, and fortifies position against competitors’ efforts to design around existing patents.
