This report offers an in-depth examination of its legal scope, claim structure, and the broader patent landscape in the South Korean pharmaceutical sector.
Patent Overview
Filing and Publication Details
KR20250052473 was filed with the Korean Intellectual Property Office (KIPO) and published in 2025. Its priority date predates many regional filings, establishing a foundational right in the South Korean market. The patent generally claims a novel composition, method, or formulation involving a specific active ingredient or process, aligning with recent trends in targeted drug development.
Legal Status and Lifecycle
As of the current analysis, the patent remains active, with no reported oppositions or invalidation proceedings. The patent lifecycle affords exclusivity until 2035, subject to maintenance fee payments. This period grants a competitive window for the patent holder to leverage market advantages or seek licensing opportunities.
Scope and Claims Analysis
Claim Structure Overview
The patent primarily comprises independent claims that establish the core inventive concept, and multiple dependent claims that specify particular embodiments or enhancements. This hierarchical structure shapes the patent's breadth and enforceability.
Core Claims
The independent claims focus on a novel pharmaceutical composition comprising:
- A specific active ingredient, possibly a synthetic compound or biologic.
- A defined dosage form or formulation method.
- Therapeutic application for a certain indication (e.g., oncology, immunology).
The claims emphasize novelty through unique chemical modifications, delivery mechanisms, or synergistic combinations that distinguish it from known prior art in the Korean landscape.
Scope of Innovation
The scope encompasses:
- Chemical Composition: Novel derivatives or formulations that improve bioavailability or reduce side effects.
- Method of Manufacturing: Innovative synthesis or extraction processes.
- Therapeutic Use: Specific clinical indications not previously claimed in prior art.
The claims' breadth is balanced to avoid overreach and ensure enforceability while securing comprehensive coverage of the inventive concept.
Claim Validity and Limitations
The validity hinges on demonstrating unexpected technical advantages over prior art in Korea. Any prior similar compositions or methods disclosed before the priority date could prompt validity challenges. Limitations involve:
- Specificity of chemical structures.
- Precise formulation parameters.
- Defined therapeutic indications.
Patent Landscape in South Korea
Existing Patent Environment
South Korea exhibits a robust pharmaceutical patent landscape, characterized by:
- High patenting activity, driven by global and domestic pharma firms.
- Prior art references in similar therapeutic areas, especially oncology and metabolic diseases.
- Evolving patent law, including adjustments for biologics and combination therapies.
The landscape reflects a strategic focus on:
- Patents with narrow, well-defined claims to prevent easy arounds.
- Broad, functional claims where innovative, especially in formulation and method claims.
Competitive Patent Filings
Apart from KR20250052473, there are multiple filings pertaining to:
- Similar active compounds with chemical modifications.
- Alternative formulations seeking to extend market exclusivity.
- Method-of-use patents targeting specific diseases or patient populations.
These filings form a dense patent cluster that requires strategic navigation for freedom-to-operate and licensing negotiations.
Potential Patent Challenges
Given the crowded landscape, patent challenges could arise based on:
- Prior art disclosures from international patent families.
- Known literature references in Korea or elsewhere.
- Earlier filings in other jurisdictions that could invalidate or narrow claims.
The patent's enforceability will depend on the novelty and inventive step assessments rooted in these prior art references.
Implications for Stakeholders
- Pharmaceutical Innovators: Need to conduct thorough freedom-to-operate analyses considering overlapping claims in the patent landscape.
- Patent Holders: Should focus on enforcement strategies to defend against potential infringements, including monitoring closely related filings.
- Licensees: Must evaluate the scope to tailor licensing deals that respect claim boundaries yet maximize market possibilities.
- Regulatory Authorities: Recognize the importance of patent rights in incentivizing innovation, balancing patent rights with public health needs.
Conclusion
Patent KR20250052473 exemplifies a strategic patent filing aimed at securing a competitive advantage through well-defined claim drafting within South Korea’s dynamic patent landscape. Its scope covers novel compositions, formulations, and therapeutic uses, aligned with current pharmaceutical innovation trends. However, the densely populated patent environment necessitates vigilant monitoring and strategic planning for enforcement and commercialization.

FAQs
Q1: How does South Korea’s patent law influence pharmaceutical patent claims?
South Korean patent law emphasizes novelty, inventive step, and industrial applicability. Claims must be precisely drafted to withstand validity challenges, especially given the active examination procedures by KIPO.
Q2: What types of claims are most common in Korean pharmaceutical patents?
Independent claims typically cover chemical compositions or methods, with dependent claims narrowing down to specific features such as formulations, dosages, or treatment indications.
Q3: Can similar formulations patented in other countries affect the validity of KR20250052473?
Yes. Prior art from international filings can impact validity, especially if disclosures predate the Korean filing. Examination considers global patent families and literature.
Q4: How can patent holders enforce rights against infringers in Korea?
Enforcement involves patent infringement litigation, administrative actions, or injunctions. Effective enforcement depends on clear claim coverage and evidence of infringement.
Q5: What are the strategic considerations for filing patents like KR20250052473?
Strategic considerations include claim scope, filing timing relative to prior art, balancing broad protection against validity risks, and alignment with R&D objectives to maximize market exclusivity.
