Key features:
- Priority date: The patent was filed in South Korea, with the relevant filing date likely around 2019-2021.
- Patent type: It is classified as a utility patent.
- Assignee: The patent is assigned to a major pharmaceutical company, indicating commercial interest.
- Patent term: Expected to expire 20 years after the filing date, assuming maintenance fees are paid.
What do the claims specify?
The claims define the legal scope of patent protection. They are structured into independent and dependent claims.
Typical Claim Structure
| Type |
Description |
| Independent Claims |
Cover the core invention—e.g., a specific drug composition, delivery method, or therapeutic use. |
| Dependent Claims |
Add limitations or specific embodiments, e.g., particular dosages, formulations, or administration routes. |
Sample claim features (hypothetical but typical):
- Composition claim: A pharmaceutical composition comprising a first active ingredient selected from a class of compounds, combined with a second component, such as a stabilizer or carrier.
- Method claim: A method of producing the composition involving a specific process step, such as mixing at a certain temperature.
- Use claim: A method for treating a certain condition by administering the composition within a defined dosage range.
Claim scope considerations
- The claims likely cover a novel API combination or a new formulation that provides improved efficacy, stability, or bioavailability.
- They could also encompass a specific therapeutic indication, e.g., a new use of an existing drug for a different disease.
How does the patent landscape look for related patents?
South Korea maintains a robust patent environment for pharmaceuticals, with strategic filings by domestic and foreign companies.
Landscape overview:
- Major filers: Liposome- and antibody-related filings, with patent families from companies like Hanmi, Yuhan, and SK Bioscience.

FAQs
Q1: How broad are the claims likely to be for KR102597622?
A: Without full claim language, it is typical that independent claims cover the core composition, process, or use, with dependent claims narrowing scope through specific embodiments.
Q2: Can the patent be challenged based on prior art?
A: Yes. If similar formulations or methods exist before the priority date, the patent could face invalidation.
Q3: How does the patent landscape in South Korea influence global patent strategy?
A: South Korean patents are often filed early and form part of a broader international strategy, including PCT applications and filings in the US, EU, and Japan.
Q4: Are biologics or small-molecule drugs more protected under such patents?
A: Both are protected, but biologics often require additional data and process-specific claims, while small molecules focus on chemical structure and formulations.
Q5: What emerging trends could impact this patent's value?
A: Advances in personalized medicine, combination therapies, and novel delivery systems could widen or narrow the patent's relevance.
