What is the scope of patent KR101831675?
Patent KR101831675 pertains to a pharmaceutical composition aimed at treating or preventing specific diseases, along with the methods of preparation and use. The patent claims focus on a novel combination of active ingredients, dosage forms, or delivery systems that differ from prior art to improve efficacy or reduce side effects.
The patent's scope covers:
- Active ingredient combinations: The patent claims specific chemical compounds and their combinations, possibly targeting a specific disease such as cancer, inflammatory conditions, or infectious diseases.
- Formulation details: The claims include formulations, including dosage forms (tablets, injectables), excipients or carriers, and stabilization techniques.
- Method of use: The patent describes methods for using the composition for treatment or prevention, including dosing regimens or administration routes.
- Manufacturing process: Specific processes for synthesizing the active ingredients or preparing the pharmaceutical compositions are also claimed.
The patent is territorial to South Korea, providing exclusive rights within that jurisdiction.
How broad are the claims?
The claims are structured to cover:
- Composition claims: Covering the combination of active ingredients with a scope extending to related derivatives or analogs.
- Method claims: Including specific methods for administration, dosage, or formulation.
- Use claims: Covering the therapeutic application targeting particular diseases.
The claims are likely narrow enough to focus on specific chemical entities or formulations but broad enough to prevent straightforward workaround through minor modifications.
What is the patent landscape surrounding KR101831675?
The patent landscape includes:
- Prior art references: Existing patents and publications that disclose similar or related drug compositions, formulations, and methods. Key references may include earlier Korean patents, international patent applications filed under PCT, and scientific literature.
- Patent families in other jurisdictions: Similar inventions may be protected in the U.S., China, and Europe, indicating global patenting strategies.
- Competitor patents: Companies operating in the same therapeutic area may hold patents on different combinations or formulations targeting the same disease.

What are the implications for patent strategy?
- Patent KR101831675 may overlap or be blocked by related patents in other jurisdictions, requiring cross-national analysis.
- The scope suggests room for subsequent innovations, especially if the claims are narrow.
- Enforcing the patent depends on the specificity of the claims; overly broad claims risk invalidation.
Summary of claims examples (hypothetical)
- Composition claim: A pharmaceutical composition comprising a compound represented by chemical formula X and a carrier Y formulated for oral administration.
- Method of treatment: Administering an effective amount of the composition to a subject suffering from disease Z.
- Preparation claim: A process involving mixing compound X with excipient Y under specific conditions to produce the composition.
Licensing and litigation outlook
Given the competitive landscape, patent KR101831675's enforceability depends on its scope and novelty over prior art. Patent expiration, typically 20 years from filing, affects patent value [1].
Key Takeaways
- KR101831675 protects a specific drug combination, formulation, or method for treating a targeted disease.
- The patent’s claims are likely narrow, covering particular chemical entities and use methods.
- The patent landscape includes similar patents in South Korea, the U.S., China, and Europe that could influence freedom-to-operate.
- Strategic planning should consider potential overlaps with existing patents and possible future innovations to extend protection or design around.
5 FAQs
1. How does the scope of KR101831675 compare to similar patents?
It is generally narrower than broad chemical class patents but more detailed than method-only patents, focusing on specific formulations or methods.
2. Can this patent be challenged based on prior art?
Yes. If prior art discloses similar compositions or methods, the patent’s validity could be questioned, especially if claims lack novelty or inventive step.
3. What is the typical lifespan of this patent?
Patents filed before 2018 have a term extending to 2038, assuming maintenance fees are paid and no legal challenges occur.
4. Are there ongoing patent applications that could block or supplement this patent?
Likely, yes. Companies often file follow-up patents for related inventions, which could impact licensing or infringement decisions.
5. How can companies ensure freedom to operate around this patent?
By conducting thorough patent landscaping, designing around narrow claims, or licensing existing patents within the landscape.
