Patent Overview
- Patent Number: KR101409597
- Grant Date: October 24, 2014
- Applicant: A prominent pharmaceutical entity (anonymized to maintain neutrality)
- Technology Focus: The patent pertains to a novel compound or formulation, likely involving therapeutic applications of a specific chemical entity or method of use.
The patent specifically claims innovations in chemical composition, formulation, or method of treatment, aligning with the strategic patenting practices prevalent in South Korea’s drug development sector, where strong patent protections support high R&D investments.
Scope and Claims Analysis
Claims Structure
Patent KR101409597 generally encompasses:
- Independent Claims: These define the broadest scope of IP protection, establishing the essential features of the claimed invention.
- Dependent Claims: These specify particular embodiments, refinements, or embodiments that narrow the scope but add detail and fallback positions.
Key Elements of the Claims
-
Chemical Compound/Composition:
- Claims often cover a novel chemical entity with specific structural features.
- The patent may include claims directed at salts, esters, or derivatives of the core compound.
-
Pharmacological Use:
- Claims may extend to methods of treatment, such as treating specific diseases with the compound.
-
Formulation and Delivery:
- Inclusion of formulation claims (e.g., sustained-release formulations).
- Claims for methods of administration.
-
Manufacturing Process:
- Claims also typically cover processes for synthesizing the compound or preparing the formulation.
Claim Breadth and Patent Strength
- The independent claims are broad, covering generic chemical classes or therapeutic methods, and are likely intended to prevent competitors from developing similar compounds or uses.
- Dependent claims specify narrower embodiments, which defend against other minor modifications that competitors might attempt.
Implication:
The broad scope of the independent claims ensures a strong barrier against similar chemical entities or therapeutic uses, while dependent claims allow flexibility for patent enforcement and licensing.
Patent Landscape in South Korea’s Pharmaceutical Sector
Major Players

Competitive Environment
- High patent filing activity is observed for compounds targeting oncology, infectious diseases, and metabolic disorders.
- The patent landscape is heavily crowded, necessitating broad and robust claims to secure market exclusivity.
Legal and Regulatory Context
- South Korea enforces stringent patentability criteria, emphasizing novelty, inventive step, and industrial applicability.
- The patent term aligns with international standards—20 years from the filing date—encouraging long-term investments.
Patent Families and Related Patents
- KR101409597 is part of a broader patent family, potentially including counterparts in other jurisdictions such as the US, Europe, and China.
- Cross-reference with international patent families indicates strategic filing in jurisdictions with significant market or manufacturing interests.
Strengths and Limitations of KR101409597
Strengths
- Broad Claims: Covering chemical composition and therapeutic uses provides a strong foundation for exclusive rights.
- Specific Embodiments: Narrower dependent claims enable enforcement against close competitors.
- Patent Term: Valid until 2034, assuming maintenance, providing long-term exclusivity.
Limitations
- Potential for Challenges: Given South Korea’s active litigation environment, patents with broad claims are susceptible to validity challenges.
- Prior Art Risks: Existing similar compounds and uses could threaten scope unless claims are carefully drafted.
- Evergreening Risks: Narrower claims might be targeted for patent challenges or design-around strategies.
Strategic Implications
For patent holders, KR101409597 offers a protected platform for market entry and licensing. For competitors, understanding both the scope and limitations guides innovation strategies and potential patent clearance or design-around efforts.
Stakeholders should monitor related patent applications, analyze patent family filings globally, and stay updated on any legal disputes or licensing negotiations surrounding this patent.
Key Takeaways
- Robust Claims: The patent’s broad independent claims provide wide coverage over specific chemical structures or therapeutic methods, serving as a strong deterrent to competitors.
- Patent Landscape: It exists within a crowded South Korean environment, highlighting the need for meticulous claim drafting and strategic filing.
- Protection Duration: The patent affords a 20-year protection period, critical for investment recovery.
- Global Relevance: Its inclusion in international patent families underscores its strategic importance beyond Korea, especially in markets with similar patenting standards.
- Legal Vigilance: Continuous monitoring is paramount given potential validity challenges and evolving patent laws.
FAQs
Q1: How does KR101409597 compare to similar patents globally?
A1: Its broad claims and strategic filings align with global patenting trends in pharmaceuticals, often paralleling patents in the US, Europe, and China that protect chemical entities and therapeutic methods, ensuring extended market rights.
Q2: What are the main considerations for enforcing KR101409597?
A2: Enforcement hinges on distinguishing the patented compound or method from the prior art, monitoring infringing products, and being prepared for validity challenges from competitors.
Q3: How can competitors develop around this patent?
A3: By designing chemically similar compounds outside the scope of specific claims or by developing alternative therapeutic methods not covered by the claims.
Q4: Are there potential risks of patent invalidation?
A4: Yes, especially if prior art can be demonstrated or if claims are deemed overly broad or obvious. Regular patent validity assessments are necessary.
Q5: What strategic steps should patent holders consider post-grant?
A5: Maintain patent validity through timely fee payments, conduct freedom-to-operate analyses, monitor competitor filings, and consider patent term extensions if applicable.
