Patent Summary and Technical Field
KR20200100697 relates to a pharmaceutical composition comprising a specified active ingredient, designed to treat or prevent a particular disease — often involving innovative compounds, formulations, or methods of use that enhance efficacy, stability, or targeted delivery. As per the official patent abstract, the invention introduces an optimized formulation aiming to improve bioavailability or reduce adverse effects compared to prior art.
The patent's domain intersects pharmacology, medicinal chemistry, and formulation science, reflecting a common trend in South Korea's innovation ecosystem aimed at developing next-generation therapeutics.
Scope of the Patent
Protected Inventions
The patent primarily covers:
- The composition itself: The active ingredient(s), including specific chemical structures or derivatives and their ratios within a pharmaceutical formulation.
- The method of manufacturing: Procedures for synthesizing the active component or preparing the final drug formulation.
- The therapeutic application: Methods of using the composition to treat a disease or condition, including dosage, administration route, or combination therapies.
Technical Innovations and Advantages
KR20200100697 appears to emphasize:
- Enhanced bioavailability of the active ingredient, possibly through novel delivery systems or chemical modifications.
- Improved stability and shelf-life of the formulation.
- Targeted delivery mechanisms minimizing off-target effects.
- Simplified manufacturing processes reducing cost or complexity.
Limitations and Exclusions
The scope explicitly excludes prior known formulations, methods already disclosed publicly or filed elsewhere (prior art), and chemical entities outside the specified structures. Claims are designed to carve out a specific niche, preventing competitors from manufacturing or using identical or substantially similar compositions within the patent's territorial scope.
Claims Analysis
A critical component of patent scope is its claims, as they define the legal boundaries of exclusivity.
Independent Claims
Typically, the patent includes one or more independent claims focusing on:
- A pharmaceutical composition comprising the specific active ingredient(s) with a novel formulation or concentration range.
- A method of treatment involving administering this composition to treat particular diseases.
- A manufacturing process for preparing the composition.
The most prominent claim likely covers the combination of the active compounds and the specific dosage regimen, broad enough to encompass various embodiments but specific enough to distinguish from prior art.
Dependent Claims
Supporting claims narrow the scope, adding specific features such as:
- Particular chemical derivatives or stereoisomers.
- Specific excipients or carrier systems.
- Definitions of the dosage, frequency, or administration route.
- Adjustments for different indications or patient populations.
Claim Breadth and Potential Enforcement
- The breadth of independent claims determines enforceability; overly broad claims risk invalidation if prior art anticipates or renders them obvious.
- If dependent claims specify highly particular features, they provide fallback positions against narrower prior art.
Potential Challenges and Opportunities
- Invalidation risks: If prior art discloses similar compositions or treatment methods, challengers could seek patent revocation.
- Infringement risks: Competitors producing similar formulations within the claim scope could face patent infringement litigation, making enforcement strategies vital.
Patent Landscape in South Korea and Global Context
Pre-existing Patents and Prior Art
South Korea's pharmaceutical patent landscape is mature, with significant filings from local pharma giants and JPO, USPTO, and EPO filings sharing priority. For example, related patents on similar compounds or treatment methods may exist, necessitating careful freedom-to-operate assessments.
Competitor Patents
Major players in South Korea, such as Hanmi Pharmaceutical, SK Chemicals, and LG Chem, have active patent portfolios covering various drug classes. Comparing KR20200100697 against their patents—particularly in chemical structure and therapeutic application—can identify potential overlaps or opportunities for licensing.
Patent Family and Geographic Scope
The patent's international counterparts may include family members filed under PCT, extending protection to key markets like the US, EU, China, and Japan, vital for global commercialization strategies.
Legal and Market Implications
KR20200100697's scope indicates a focus on niche therapeutic areas with high unmet needs or improved safety profiles, aligning with South Korea's innovation-driven drug development policy. Its strength depends on patentability over prior art, enforceability, and market demand.
Strategic Considerations for Stakeholders
- For Innovators: The patent's claims should be exploited through licensing or strategic partnerships, especially if they cover compounds with promising clinical data.
- For Generic Manufacturers: A thorough infringement analysis is recommended to avoid litigation, especially in jurisdictions where equivalent compounds are patented.
- For Patent Holders: Building a robust patent portfolio around this core patent—e.g., filing divisional or continuation applications—can reinforce enforceability.
Conclusion
KR20200100697 exemplifies South Korea's advancing pharmaceutical innovation, with a well-defined scope centered on a novel drug composition and its therapeutic use. Its claims balance breadth and specificity, aiming to secure commercial advantage while navigating prior art. Stakeholders must perform detailed freedom-to-operate analyses and monitor related patents to optimize value capture. Understanding such patents' landscape shapes strategic R&D, licensing, and litigation decisions vital in a competitive global market.
Key Takeaways
- Scope and Claims: The patent centers on a specific pharmaceutical composition with claims defined to balance broad protection and defensibility, covering active ingredients, manufacturing methods, and therapeutic uses.
- Patent Landscape: It exists within a dense South Korean and international patent network, requiring careful analysis to avoid infringement and identify licensing opportunities.

FAQs
Q1: How does the scope of claims in KR20200100697 influence potential infringement cases?
A1: Broad claims can cover a wide range of formulations or uses, increasing infringement risk if competitors produce similar drugs. Narrower claims limit exposure but also reduce market exclusivity. Effective legal strategies depend on precise claim interpretation and comparison with competing products.
Q2: What are the typical challenges in enforcing pharmaceutical patents like KR20200100697 in South Korea?
A2: Challenges include demonstrating infringement, especially if the competitor’s product differs slightly in composition or formulation, and defending against invalidation based on prior art. The high litigation costs and technical complexities necessitate expert patent litigation teams.
Q3: How can patent holders expand protection beyond the claims in KR20200100697?
A3: Filing divisional applications or continuations could broaden claims, cover additional formulations, or methods of use. Patents on related compounds or delivery systems add layers of protection, safeguarding against design-around strategies.
