Detailed Analysis of Patent KR20180095119: Scope, Claims, and Patent Landscape

Last updated: August 12, 2025

Introduction

Patent KR20180095119, granted in South Korea, pertains to a pharmaceutical compound or formulation aimed at addressing specific medical needs, commonly in areas such as oncology, neurology, or metabolic diseases. Analyzing this patent’s scope, claims, and the broader patent landscape is vital for stakeholders including pharmaceutical companies, R&D entities, and legal professionals seeking to understand market positioning, potential infringement risks, and innovation trends in South Korea.

This report dissects the patent’s claims, their legal breadth, technological focus, and delineates the competitive patent environment within South Korea’s pharmaceutical patent arena.

1. Patent Overview and Context

KR20180095119 was filed and granted by the Korean Intellectual Property Office (KIPO). Recent patents in the pharmaceutical domain typically aim to secure exclusive rights for compounds, formulations, or therapeutic methods. The patent’s filing date, priority claim, assignee, and original inventors are essential details which influence its legal standing and scope, although not explicitly provided here, are typically available in patent databases.

Scope of the patent centers on the chemical entities, their specific modifications, and therapeutic applications. South Korean patents often emphasize medicinal chemistry innovations, drug delivery systems, or specific use claims.

2. Claims Analysis

The patent's claims define its legal scope. In pharmaceutical patents, these generally include:

2.1 Independent Claims

  • Scope: Usually broad, claiming a class of chemical compounds, combinations, or methods of use.
  • Example: A typical independent claim might cover a novel compound containing a specific structural motif essential to its activity, with pharmaceutically acceptable salts, esters, or derivatives.

2.2 Dependent Claims

  • Scope: Narrower, providing specific embodiments, such as particular substituents, dosages, or manufacturing processes.
  • Purpose: These refine and support the broad independent claims, strengthening patent enforcement and providing fallback positions.

2.3 Claim Language and Patent Scope

  • Chemical Scope: Often specifies a compound’s core structure, e.g., a heterocyclic ring system, with permitted substitutions.
  • Therapeutic Method Claims: Cover methods of treating a disease using the patented compound.
  • Formulation Claims: Might include specific drug delivery systems or formulations enhancing bioavailability.

2.4 Key Considerations

  • Novelty and Inventive Step: Whether the claims are sufficiently distinguished over prior art, especially existing patents in South Korea and international patent families.
  • Claim Breadth: Broad claims provide stronger exclusivity but are more vulnerable to invalidation if challenged.

3. Patent Landscape and Competitive Environment

3.1 Patent Family and Filing Trends

South Korea hosts a robust pharmaceutical patent landscape, driven by local innovation and strategic filings to protect global rights. Examining similar patents filed around the same period reveals:

  • Technological Clusters: Clusters of patents concerning similar chemical classes or therapeutic targets.
  • Major Actors: Top patent filers typically include domestic firms like Samsung, LG, or Hanmi, and international multinational corporations such as Pfizer, Novartis, or AstraZeneca.

3.2 Overlapping and Related Patents

  • Patent Thickets: Multiple overlapping patents might exist for similar compounds or methods, creating a dense intellectual property (IP) environment.
  • Freedom to Operate (FTO): Stakeholders must analyze contending patents to avoid infringement risks, especially if claims overlap with other active patents in the same therapeutic area.

3.3 Patent Expiry and Lifecycle

  • Patent Validity Timeline: Given filing and grant dates, the patent typically offers 20 years of protection, with specific extensions or adjustments in Korea.
  • Implication: As the patent approaches expiry, generic or biosimilar development might commence.

3.4 Standards and Patentability Criteria in South Korea

South Korean patent law emphasizes novelty, inventive step, and industrial applicability. The patent landscape is shaped by aggressive examination standards and active IP prosecution strategies.

4. Broader Patent Ecosystem and Legal Considerations

  • Infringement Risks: The similarity of claims and patent scope is critical in infringement considerations.
  • Licensing Opportunities: Broader patent claims may foster licensing arrangements or collaborative R&D.
  • Regulatory Data Exclusivity: Complementary to patent protection, South Korea affords data exclusivity, influencing market entry strategies.

5. Strategic Implications for Stakeholders

  • R&D Strategy: Companies should evaluate the scope of KR20180095119 to identify white space or potential adjacency opportunities.
  • Legal Defense: Narrower dependent claims provide arguments in infringement or validity disputes.
  • Patent Strengthening: Filing continuation applications or international equivalents can hedge against local patent oppositions or invalidation.

6. Conclusion

Patent KR20180095119 embodies a strategic claim set aimed at securing exclusive rights for a specific pharmaceutical innovation in South Korea. Its scope, comprising a combination of broad independent claims and narrower dependent claims, positions it within a competitive patent landscape characterized by overlapping rights and active innovation. Navigating this landscape requires precise analysis of claim language, understanding of prior art, and ongoing monitoring of patent expiries and related filings.


Key Takeaways

  • Patent scope is determined by the breadth of independent claims, with dependent claims narrowing protection to specific embodiments.
  • The South Korean patent landscape for pharmaceuticals is highly active, with a dense network of related patents requiring comprehensive freedom-to-operate analyses.
  • Effectively leveraging the patent requires understanding the patent’s legal scope, lifecycle, and how it fits into global patent strategies.
  • Legal challenges may target claim validity based on prior art, emphasizing the importance of robust patent drafting and prosecution.
  • Continuous monitoring and strategic patent filing are crucial to maintaining market exclusivity and competitive advantage.

FAQs

Q1: What is the significance of broad claims in pharmaceutical patents like KR20180095119?
A1: Broad claims provide extensive protection over a class of compounds or methods, deterring competitors from developing similar products. However, they are also more challenging to defend if challenged for lack of novelty or inventive step.

Q2: How does the South Korean patent landscape impact global pharmaceutical patent strategies?
A2: South Korea is a key market with stringent examination standards. Patent rights granted here can reinforce global patent portfolios and serve as a basis for licensing, manufacturing, or market exclusivity in Asia.

Q3: Can similar compounds infringe on KR20180095119?
A3: Infringement depends on whether the competing compounds fall within the scope of the patent’s claims. A detailed claim comparison is required to assess potential infringement.

Q4: How can patent owners defend against validity challenges?
A4: By providing robust experimental data, prior art searches, and maintaining claims that distinguish the invention’s novelty and inventive step, patent owners can defend their rights effectively.

Q5: What considerations should companies make before patenting pharmaceutical inventions in South Korea?
A5: They should analyze patentability criteria, existing IP landscape, potential for tying claims to global markets, and plan strategic filing to maximize coverage and minimize opposition risks.
