Scope of Patent KR101814474
The patent’s scope delineates the extent of legal protection conferred. It encompasses the invention's technological features, potential applications, and the permissible variations that do not infringe upon its claims.
Key Aspects:
-
Therapeutic Focus: The invention targets a specific disease entity, possibly related to neurodegenerative, metabolic, or infectious diseases, depending on the claims. Its scope hinges on the particular molecules, formulations, or methods described.
-
Innovative Elements: The scope likely extends to novel compounds, drug delivery systems, or manufacturing processes that offer improved efficacy, stability, or safety profiles.
-
Claim Breadth: The patent’s scope is influenced by how broadly the claims are drafted. Broad claims encompass various embodiments, while narrow claims focus on specific structures or methods.
-
Temporal and Geographic Coverage: As a South Korean patent, the scope is limited geographically but may impact patent strategies for regional and international filings via patent family extensions.
Analysis of the Claims
The claims form the core legal language establishing the patent's boundaries.
Claim Types and Strategies
-
Independent Claims: Typically, these specify the core invention—often a compound, formulation, or method—without reference to other claims. The scope here determines the breadth of legal protection.
-
Dependent Claims: These narrow down the inventive features, adding specific limitations or embodiments, which can be crucial for enforcement and avoiding prior art challenges.
Claim Structure and Clarity
-
The claims likely include chemical structures, dosage forms, or treatment methods, defined with precision to withstand validity scrutiny.
-
The inclusion of Markush groups or functional language may enhance claim breadth but also invite validity challenges.
Potential Claim Challenges
-
Anticipation and Obviousness: Given prior patents and literature, claims must be sufficiently inventive and non-obvious to avoid invalidation.
-
Overlap with Existing Patents: The scope must be unique enough to avoid overlap with prior art in the same therapeutic domain, especially within the densely crowded South Korean patent landscape.
Patent Landscape in South Korea for Similar Drugs and Technologies
South Korea, a technology-forward country with a robust biotech sector, maintains a dynamic patent environment for pharmaceuticals.
Major Patent Holders
-
Leading pharmaceutical firms such as Samsung Biologics, Hanmi Pharm, and Celltrion actively build patent portfolios covering novel compounds, formulations, and manufacturing processes.
-
International corporations, including Pfizer, Novartis, and Merck, also seek patent protection within Korea, leading to a highly competitive landscape.
Patent Trends
-
Emphasis on biologics and biosimilars, with many patents targeting advanced drug delivery systems, recombinant DNA-based therapies, and targeted treatments.
-
Growing patent filings concerning combination therapies and personalized medicine.
Legal and Regulatory Environment
-
The Korean Intellectual Property Office (KIPO) enforces stringent examination standards, emphasizing inventive step and novelty, particularly for chemical and biotech patents.
-
Recent decisions suggest increased focus on patent clarity and the scope of claims, making comprehensive and well-crafted patent claims vital.
Implications for Patent Strategy and Competition
-
Infringement Risks: The dense patent landscape requires meticulous freedom-to-operate analyses before product development.
-
Patent Thickets: Overlapping claims may create patent thickets, necessitating strategic licensing or design-around approaches.
-
Innovation Incentives: Patents like KR101814474 serve as barriers to entry but also promote ongoing innovation within specific therapeutic domains.
-
International Strategy: Given the global nature of pharma markets, KR patents often function as a springboard for international filings through Patent Cooperation Treaty (PCT) routes or direct filings in key jurisdictions.
Legal and Commercial Considerations
-
Validity and Enforceability: The strength of the claims and their resilience against prior art invalidation are critical.
-
Patent Term and Market Timing: The lifespan of the patent influences market exclusivity and return on investment—patents filed early in the development process secure longer market protection.
-
Litigation and Licensing: Enforcement potential depends on the clarity of claim scope, and licensing opportunities hinge on the patent’s perceived value.
Conclusion
Patent KR101814474 exemplifies a targeted effort to secure proprietary rights over a specific pharmaceutical invention in South Korea. Its scope and claims are tailored to balance broad protection with defendability against prior art. The patent landscape in South Korea is characterized by vigorous innovation, particularly in biologics and advanced formulations, which positioning dictates strategic patent drafting and enforcement approaches. Stakeholders must monitor similar patents, refine their claim strategies, and consider international pathways to maximize commercial advantage and safeguard innovation.
Key Takeaways
-
Strategic Claim Drafting is Essential: Broad claims expand protection but must be carefully crafted to withstand validity challenges.

FAQs
1. What is the typical scope of pharmaceutical patents like KR101814474?
Pharmaceutical patents generally cover specific compounds, formulations, methods of manufacture, or treatment methods. The scope depends on how broadly the claims are drafted, balancing protection with validity and clarity.
2. How does the South Korean patent landscape influence pharmaceutical patent strategies?
South Korea’s rigorous patent examination standards and active biotech industry necessitate precise, non-obvious, and innovative claims. Companies often file comprehensive patent families and conduct thorough freedom-to-operate analyses.
3. Can a patent like KR101814474 be used to block generic entry?
Yes. If the patent’s claims are valid and broad enough, they can prevent generic manufacturers from launching similar products without licensing or design-around strategies.
4. What role do claims play in patent litigation?
Claims define the patent’s legal scope. In litigation, infringement is determined based on whether the accused product or process falls within the scope of the claims.
5. How does patent claim drafting influence patent validity?
Precise, clear, and inventive claims increase the likelihood of passing validity challenges while broad claims offer more comprehensive protection, but can be more vulnerable if overly broad or vague.
