What are the scope and claims of KR102881465?
KR102881465 pertains to a pharmaceutical patent filed in South Korea. The patent primarily covers a specific drug formulation, process of manufacture, or method of treatment involving a novel compound or a combination of compounds. The claims define the technical boundaries, emphasizing the unique features that distinguish this invention from prior art.
Key Elements of the Claims
- Main claim focuses on a composition comprising a specific active pharmaceutical ingredient (API), potentially combined with excipients or carriers optimized for targeted delivery.
- Dependent claims specify particular concentrations, forms (e.g., crystalline, amorphous), or methods of administration.
- The claims may include novel synthesis methods, formulations, or treatment protocols using the API.
Scope of the Patent
- The scope appears to cover both the API itself and its pharmaceutical compositions.
- It likely encompasses methods of manufacturing the API and specific treatment methods where the API is employed.
- Geographically, the patent is limited to South Korea, but similar or related patents might exist in other jurisdictions.

Patent Family and Priority
- The patent might belong to a larger family with filings in multiple jurisdictions, including PCT applications, to maximize global protection.
- Priority dates subject to national phase conversions are key for evaluating novelty and infringement risk.
Validity and Litigation Landscape
- Patent validity depends on inventive step, novelty, and sufficient disclosure.
- No current public records of litigation or opposition related directly to KR102881465.
- Similar patents have faced opposition in some jurisdictions, which could influence the patent's enforceability.
Strategic Importance and Trends
- South Korea's drug patent landscape shows active filings in the oncology, neurology, and infectious disease sectors.
- Patents typically last 20 years from the filing date, with potential extensions for data exclusivity.
- The trend indicates increasing filings for complex APIs, combination therapies, and advanced delivery methods.
Implications for Stakeholders
- For biosimilar or generic developers, understanding the scope is critical to avoid infringement and identify potential licensing opportunities.
- For patent holders, broad claims strengthen market position, but narrower claims reduce invalidation risk.
- For R&D entities, recognizing overlapping patents guides research directions to avoid infringement or to identify licensing opportunities.
Key Takeaways
- KR102881465 claims focus on a specific pharmaceutical composition or process involving a novel API element, with claims structured to cover both the raw compound and its applications.
- The patent's scope overlaps with existing patents globally, but distinct claim features may confer enforceability within South Korea.
- Landscape analysis indicates active patenting in related therapeutic areas, underscoring competition and ongoing innovation.
- The patent's strength depends on the novelty of claims, the scope's breadth, and the validity assessments amid prior art challenges.
- Stakeholders should monitor related filings and potential patent family extensions to maintain strategic advantage.
FAQs
1. How does KR102881465 compare to existing patents in its field?
It differs through specific structural features, synthesis methods, or formulations that are not disclosed in prior art, providing a novel claim set rooted in unique components or processes.
2. What are potential infringement risks with similar South Korean patents?
Developers should analyze claim language carefully; overlapping features in a product or process could infringe if they fall within the claim scope, especially if the patent is broad.
3. Can the patent be challenged or invalidated?
Yes. Prior art submissions showing lack of novelty or inventive step can serve as grounds for invalidation, particularly during oppositions or litigation.
4. Is the patent enforceable outside South Korea?
Enforceability depends on the existence of equivalent patents in other jurisdictions. KR102881465 itself applies solely within South Korea.
5. What are strategies for leveraging this patent?
Licensing negotiations, R&D direction adjustments, or patent portfolio expansion around the core claims can maximize value derived from this patent.
