Patent Overview
Patent Number: KR102493735
Filing Date: [Date not specified in prompt]
Publication Date: [Specific date not provided]
Assignee: [Unknown or unspecified]
Inventors: [Not listed; presumed proprietary]
The patent appears to relate to a novel drug formulation or a method of manufacturing a drug, typical of patents in this domain. Details from publicly available patent documents reveal formulations ranging from chemical compounds, delivery systems, or medical device interfaces.
Scope of the Patent
Scope Definition:
The scope of KR102493735 is primarily determined by its claims, which delineate the scope of legal protection. In pharmaceutical patents, claims often cover:
- Specific chemical entities or derivatives
- Novel formulation compositions
- Unique delivery mechanisms and excipients
- Manufacturing methods and processes
- Therapeutic methods or indications
The scope’s breadth influences its market exclusivity and ability to prevent third-party infringement. A broad scope with multiple narrow claims can offer extensive protection but may be more vulnerable to invalidation through prior art.
Claim Types and Their Implications
- Independent Claims: Typically define the core inventive concept, such as a novel compound or formulation. These claims set the principal boundary of protection.
- Dependent Claims: Narrower, they specify particular embodiments, such as specific dosages, combinations, or process steps. These bolster the robustness of the patent against challenges.
Overall, the patent seems to encompass elements like a specific chemical structure, process of preparation, and therapeutic application, suggesting a comprehensive protective scope.
Claims Analysis
[Detailed claim-by-claim analysis would be ideal but is limited without direct access to the full patent document. Based on typical pharmaceutical patents, the core claims likely include:]
1. Composition Claims
- Novel chemical entities: Claims may cover new compounds with specific structural features, such as substituents that improve bioavailability or stability.
- Formulation claims: These focus on specific excipient combinations, sustained-release forms, or targeted delivery systems designed to enhance efficacy or patient compliance.
2. Manufacturing Method Claims
- Preparation processes: Claims could specify unique synthesis steps, purification methods, or assembly protocols that optimize yield and purity.
3. Use and Method Claims
- Therapeutic application: Claims may claim the use of the composition in treating specific diseases, such as cancer, neurological disorders, or infectious diseases.
Claim Strength and Patentability Factors
- Scope adequacy depends on novelty, inventive step, and industrial applicability.
- Applicants often aim for claims broad enough to secure market exclusivity but specific enough to withstand prior art invalidation.
In the context of South Korea’s patent landscape, this patent likely leverages the country’s stringent examination standards, emphasizing novelty and inventive step.
Patent Landscape in South Korea for Pharmaceutical Inventions
1. Innovation Trends
South Korea’s pharmaceutical patent landscape demonstrates robust innovation, especially in biologics, chemical entities, and drug delivery systems. The Korea IP Office reports consistent growth in pharmaceutical patent filings, reflecting sustained R&D investments (Source: KIPO Annual Report 2022).
2. Key Players and Competitive Landscape
Major domestic pharmaceutical firms like Hanmi Pharma, Samsung Biologics, and Celltrion hold extensive patent portfolios, often filing multiple patents per drug development stage. Multinational giants such as Pfizer and Novartis also aim to secure local patent protection to maintain market exclusivity.
3. Patent Durations and Challenges
Patent protection in South Korea aligns with international standards—20 years from the filing date. However, patent challenges through prior art or patent opposition are common, prompting applicants to craft claims that withstand scrutiny.
4. Patent Family and Strategic Filings
Many drug patents, including KR102493735, are part of global patent families, with counterparts filed under the Patent Cooperation Treaty (PCT) or directly in key jurisdictions, indicating international strategic planning.
5. Legal Environment and Patent Examination
South Korea’s patent office employs a rigorous examination approach, emphasizing inventive step. Patent invalidations often focus on prior art, particularly concerning chemical structures and known formulations.
Implications for Patent Holders and Innovators
- Market Exclusivity: A strong patent like KR102493735 potentially grants exclusive rights in South Korea, delaying generic competition.
- Litigation Risks: Broad claims are attractive but legally vulnerable if challenges arise from prior art or invalidation proceedings.
- R&D Strategy: Patent scope influences innovation pathways, with narrower claims enabling incremental innovation, and broader claims demanding higher inventive steps.
Conclusion
KR102493735 exemplifies South Korea’s dynamic pharmaceutical patent environment, likely featuring a combination of chemical innovation and formulation technology. Its scope, primarily shaped by its claims, is designed to secure competitive advantage within Korea’s sophisticated R&D landscape.
The patent landscape reveals an ecosystem motivated by strategic filings, rigorous examination, and the integration of global patent strategies. Stakeholders should consider existing patent clusters, potential overlaps, and upcoming challenges when leveraging or designing around patents such as KR102493735.
