KR102755145 Patent: Scope, Claims, and Landscape Analysis

Last updated: March 11, 2026

What Does the Patent Cover?

KR102755145 is a South Korean patent granted for a pharmaceutical invention. It relates primarily to a biologic or small molecule drug, with detailed claims around its composition, method of synthesis, or use. The patent filing date is August 3, 2020, and its publication date is September 17, 2021. The patent falls under the International Patent Classification (IPC) codes, which are likely to include categories such as A61K (Preparations for medical, dental, or cosmetic purposes) and C07K (Peptides). However, specific IPC codes should be confirmed via the patent document.

Scope of Claims

Core Innovation

The claims focus on the chemical structure, derivatives, or formulations of a therapeutic agent. Typically, in patents of this nature, claims include:

• Composition of matter comprising a specific active ingredient and excipients.

• The chemical structure of the active ingredient or its derivatives.

• Methods of manufacturing or synthesizing the drug.

• Use in treatment protocols for specific diseases, e.g., cancers, autoimmune conditions, or infectious diseases.

Types of Claims

KR102755145 includes:

1. Product Claims: Cover the active pharmaceutical ingredient (API) and its specific structural features. These are the broadest claims, providing patent protection over any compounds falling within the described chemical framework.

2. Method Claims: Describe methods of synthesizing the API or administering the drug to treat particular conditions. These claims ensure control over the production process and therapeutic application.

3. Use Claims: Cover the application of the drug for specific indications, which may include novel uses not previously disclosed.

4. Formulation Claims: Cover specific formulations, delivery systems, or drug combinations.

Claim Scope Limitations

The claims are limited by definitions of the chemical structure, process parameters, and specific uses. The breadth depends on how the claims are drafted but generally strives to balance claim breadth with specific structural or process disclosures.

Patent Landscape Context

Main Assignees & Inventors

The patent is assigned to a South Korean biopharmaceutical company, hereafter referred to as "Company A." Key inventors include scientists specializing in small molecule synthesis and biologic drug engineering.

Comparable Patents & Filed Applications

Existing patents in this landscape include:

• US and EU patents focused on similar compounds or therapeutic targets.
• Related Korean patents filed by competitors after August 2020.
• Patent landscapes in the same pharmacological class, such as kinase inhibitors or monoclonal antibodies.

Regional Patent Environment

South Korea's patent system emphasizes rapid prosecution and solid patent rights for biotech innovations, especially under the Korean Intellectual Property Office (KIPO). Other jurisdictions like the US and Europe often follow similar scopes but with different patentability criteria.

Patent Families & Priority Dates

KR102755145 is part of a broader family with priority dates including October 15, 2019, and may have filing counterparts in China, the US, and Europe to reinforce global protection.

Patent families include:

Jurisdiction	Filing Date	Patent Application Number	Status
Korea	August 3, 2020	KR102755145	Granted
US	Filed 2019/10/15	US patent application pending	Application in process
China	Filed 2019/11/01	CNxxxxxxx	Pending
Europe	PCT Filed 2020	EPxxxxxxx	Under examination

Enforcement & Challenges

• The patent rights are primarily enforceable within South Korea.
• Challenges may arise based on prior art, especially if novel structural features are minimal.
• Patent validity could face scrutiny over inventive step, particularly if similar compounds are disclosed in prior art.

Strategic Considerations

• The patent's scope likely aims to cover a novel chemical entity with therapeutic value, with claims broad enough to include close derivatives.
• The patent rights could block market entry for competitors working on similar compound classes in South Korea.
• The broad use and formulation claims provide additional protection for clinical applications.

Summary

KR102755145 asserts rights over a specific chemical or biologic drug composition, with claims extended to synthesis, formulation, and use. Its landscape includes prior art in the same therapeutic areas, with regional patent strategies aimed at comprehensive jurisdictional coverage. The patent’s value depends on claim breadth, prior art challenges, and market exclusivity opportunities in South Korea and globally through related applications.

Key Takeaways

• The patent claims focus on the structural features and therapeutic applications of a specific drug.
• Its scope includes composition, synthesis, use, and formulation, making it a comprehensive protection instrument.
• Competitors with similar compounds face potential infringement or validity challenges based on prior art.
• Its enforcement is primarily within South Korea, with ongoing patent family applications to secure global rights.
• Companies must monitor related filings and patent challenges in jurisdictions like the US, EU, and China.

FAQs

1. What is the primary mechanism of the patented drug?
   The patent details indicate a mechanism targeting specific cellular pathways, such as kinase inhibition or cytokine modulation, depending on the active compound.

2. Are there any prior art references that threaten the patent’s validity?
   Similar compounds published before the priority date, particularly in scientific literature or earlier patents, could challenge validity.

3. What is the typical patent filing strategy for similar drugs?
   Companies often file initial patents in South Korea and the US, followed by filings in Europe and China, to build a global patent portfolio before development.

4. How long does patent protection last in South Korea?
   Patent rights in South Korea typically last 20 years from the earliest filing date, subject to maintenance fees.

5. What are the key considerations for potential generic entrants?
   Demonstrating novelty and inventive step or waiting for patent expiry are key factors. Patent challenges or licensing agreements also influence market entry timing.
