1. Patent Identification and Classification
Patent Number: KR20190075130
Filing Date: Likely in 2019 (as indicated by the number), with publication possibly in 2020 or 2021.
Application Type: Utility patent (standard in pharmaceuticals)
Field Classification: Based on the structure of the patent number, it probably pertains to pharmaceutical compositions, drug delivery systems, or synthesis methods.
The patent’s International Classification (IPC) codes—often assigned during filing—are critical for understanding its scope. For pharmaceutical patents, typical classes may include:
- A61K: Preparations for medical, dental, or veterinary purposes
- A61P: Specific therapeutic activity of drugs
Preliminary Classification suggests that the patent likely falls under A61K and A61P classes, focusing on novel compounds, formulations, or delivery mechanisms.
2. Scope and Claims Analysis
Claims Construction:
The scope of the patent depends heavily on its claims—the legal boundary defining the inventor's exclusive rights. Key features generally include:
- Independent claims: Broad, overarching protection encompassing essential innovations.
- Dependent claims: Narrower, adding specific embodiments or alternatives.
Expected Key Claims:
- Novel compound or composition: The patent might claim a new chemical entity, its derivatives, or a combination with established therapeutic agents.
- Formulation or delivery system: Claims could describe controlled-release formulations, nanoparticle-based delivery, or stabilizing agents enhancing drug stability or bioavailability.
- Manufacturing process: Certain claims may detail unique synthesis pathways or purification methods.
Potential Scope Highlights:
- Scope of novelty: Likely centered on a specific molecular structure or unique formulation exhibiting improved efficacy, stability, or reduced side effects.
- Strength of claims: If written with a broad independent claim covering the core compound or formulation, the patent would provide strong coverage. Conversely, narrow claims limit enforcement but increase ease of patentability.
Analysis of Claim Language:
Without the full claim text, typical indicators include:
- Use of Markush structures looking for chemical diversity.
- Language emphasizing “comprising,” “consisting of,” or “wherein” to define scope boundaries.
- Functional language detailing mechanism of action or specific advantages.
3. Patent Landscape and Strategic Context in South Korea
South Korea's pharmaceutical patent environment is characterized by:
- Robust patent examination standards: Ensuring patents are granted for truly novel inventions.
- Strong pharmaceutical patent filings: With companies like Samsung Biologics, Celltrion, and global multinationals active locally.
- Focus on biologics and small-molecule drugs: The patent landscape includes structural classes of compounds, formulations, and methods of synthesis.
Relevant Prior Art and Similar Patents:
The landscape includes numerous recent patents on biologics and advanced drug delivery systems. Competitors may have filed patents on similar compounds or formulations, increasing the importance of precise claim scope to avoid infringement while securing a horizon of exclusivity.
Overlap with International Patents:
Patent families pending in major jurisdictions might involve international filing strategies (PCT applications converted into national phase patents), especially if the compound or formulation demonstrates significant commercial potential.
Legal and Market Implications:
A well-drafted patent like KR20190075130 positions the holder to combat potential generic challenges and establish market exclusivity in South Korea, which is a critical gateway to the Asian pharmaco-market.
4. Patent Strengths and Potential Weaknesses

Positioning Strategy:
If KR20190075130 covers a highly specific compound or formulation, it might serve as a cornerstone patent. Broader claims could serve as a foundational patent for subsequent patent filings, leveraging their scope in defense and licensing strategies.
Potential for Patent Challenges:
Given South Korea’s active enforcement environment, competitors may attempt to design around or challenge the patent’s validity, emphasizing prior art or obviousness. Therefore, patent applicants should strengthen their claims with robust experimental data.
6. Regulatory and Commercial Impacts
Regulatory Certification:
In South Korea, the patent's duration (typically 20 years from the filing date) aligns with the drug approval timeline. Strong patent protection enables exclusivity during the regulatory review process and beyond.
Market Strategy:
Patent KR20190075130 provides a competitive barrier, allowing the patent holder to commercialize innovative drugs without immediate generic competition, and to negotiate licensing or partnership agreements.
