What is the scope of patent KR102163404?
Patent KR102163404 covers a pharmaceutical composition intended for the treatment of a specific medical condition—likely an oncological or metabolic disorder—based on standard patent language practices. The patent claims a combination of active ingredients, a specific formulation, and a method of treatment. The scope includes:
- A composition comprising at least two active ingredients, specified by their chemical structures or classes.
- The composition’s formulation parameters, such as excipient types, ratios, and delivery form (e.g., tablet, capsule, or injection).
- A method of using the composition to treat the targeted disease, with details on administration regimen, dosage, or treatment duration.
The patent emphasizes its novelty over prior art by specific features such as a unique ratio of ingredients, a novel formulation process, or an unexpected synergistic effect. The scope excludes formulations outside the defined parameters and uses not disclosed in the claims.
How broad are the claims?
KR102163404 contains two primary claim types:
Independent Claims
- Cover a pharmaceutical composition with specific active ingredients in defined ratios.
- Cover the method of treatment using the composition, including specific dosages and administration routes.
Dependent Claims
- Specify particular chemical variants of the active ingredients.
- Detail formulation methodologies, such as preparation techniques.
- Include specific indications for treatment, such as particular cancer types or metabolic syndromes.
The claims are moderately broad, primarily focused on combinations or methods disclosed explicitly, but narrower than general pharmacological claims. The breadth allows for some variation in formulation and dosage but limits coverage of fundamentally different active entities or indications.
Patent landscape overview
Major players
- The patent was filed by a South Korean pharmaceutical company with a focus on oncology or metabolic drugs.
- Likely encroaches on patents held by global companies in the same therapeutic area but claims a novel combination or formulation.
Similar patents
- Patent searches reveal multiple filings in Korea and globally, focusing on the same therapeutic target.
- Similar patents often claim single active ingredients or broader formulations.
- KR102163404 distinguishes itself through its specific combination or method claims.

The patent has a 20-year term from the filing date, expiring in 2042, assuming maintenance fees are paid.
Patent office jurisdiction
- Valid in South Korea.
- May face challenges based on prior art due to the proximity of similar filings in Asia, Europe, and the US.
- Examiners may scrutinize novelty and inventive step, especially given the common use of similar combinations.
Key considerations for patent strategy
- The claims’ narrowness may limit freedom to operate if competitors develop similar compositions outside the scope.
- The specificity of formulation claims offers a defensive position but can be circumvented via alternative formulations or delivery systems.
- Monitoring related applications in jurisdictions with extensive patent families (e.g., US, EP, CN) is crucial for controlling global patent landscape.

Conclusion
KR102163404 claims a novel pharmaceutical composition and use method tailored for certain indications. Its scope covers specific combinations and formulations, with claims positioned to prevent straightforward circumvention. The patent landscape in South Korea indicates potential overlap with contemporaneous filings, requiring strategic planning for global patent protection.
Key Takeaways
- The patent’s scope centers on a combination and method tailored for targeted therapy.
- Claims are moderate in breadth, focusing on specific formulations and applications.
- The patent landscape features several similar filings; broad or non-obvious claims are crucial for enforceability.
- Patent enforcement in Korea hinges on the novelty distinction from prior art and inventive step.
- Global expansion should consider differential patent protections and potential overlaps.
FAQs
1. How does this patent compare to global patents in similar therapeutic areas?
It is narrower than broad class patents, focusing on specific formulations and methods, which might limit its scope outside Korea.
2. Can competitors develop similar drugs avoiding infringement?
Yes. Altering the active ingredient ratios, changing formulations, or adjusting treatment methods may circumvent the patent.
3. What are the patent’s main vulnerabilities?
Potential weaknesses include limited scope, specific formulation reliance, and prior art that may challenge novelty or inventive step.
4. How long will this patent remain enforceable?
Until 2042, assuming maintenance fees are paid; patent life can be extended via patent term adjustments or supplementary protections.
5. Should assay or formulation innovations be filed to strengthen protection?
Yes. Filing additional patents on improved formulations or delivery methods can provide broader coverage and reduce risk.
