Publication Date: Typically within 1-2 years post-filing, likely around 2008-2009
Ownership: Usually assigned to a pharmaceutical corporation or research entity (specific owner to be confirmed)
Priority Claims: Might reference previous filings domestically or internationally (e.g., PCT or Paris Convention filings).
Technical Field: The patent relates broadly to pharmaceuticals—probably an active pharmaceutical ingredient (API), formulation, or method of treatment.
Scope and Claims Analysis
Scope of the Patent
The scope of KR100665919 encompasses the specific chemical entities, processes, or formulations claimed within the patent. The patent’s broad scope determines its strength against competing innovations.
Key features:
- Chemical Composition or Compound: Usually, the patent claims a specific chemical structure or class of structures with certain functional groups conferring therapeutic benefits.
- Method of Use: It might cover a therapeutic method—e.g., treating a disease such as cancer, depression, or metabolic disorders using the compound.
- Manufacturing Process: Claims may include a method for synthesizing the compound or preparing the formulation.
- Drug Formulation: Specific dosage forms, delivery systems, or combinations.
The patent likely aims to protect a novel compound with improved efficacy, reduced side effects, or enhanced stability, or a novel synthesis route.
Claims Breakdown
The claims are the core legal protection of the patent. Based on typical pharmaceutical patents, they probably include:
1. Composition Claims
- Claim to a chemical compound of a specific structure, often represented by a formula.
- Claims extend to salts, stereoisomers, esters, or hydrates of the compound.
2. Method of Treatment Claims
- Claims that the compound is effective in treating specific conditions.
- Typically specify dosage ranges and administration methods.
3. Manufacturing Process Claims
- Claims describing steps for synthesizing the compound or formulation.
4. Formulation and Delivery System Claims
- Claims on particular formulations, e.g., controlled-release tablets, injectables, or topical preparations with the active compound.
Claim Breadth and Validity
The strength of claims in KR100665919 hinges on:
- Novelty: The claims must specify features not disclosed publicly before the filing date.
- Inventive Step: The claims should go beyond existing knowledge, demonstrating inventive activity.
- Scope: Broad claims—covering a wide class of compounds or methods—offer stronger protection but are more vulnerable to invalidation if prior art surfaces.
- Specificity: Well-defined structural formulas and process steps bolster enforceability.
Implication: Given the period of filing (~2006-2007), the claims likely target a specific, novel API along with its therapeutic method, aligning with common practices during that era.
Patent Landscape in South Korea and Globally
Regional Patent Environment
South Korea exhibits a robust pharmaceutical patent system, governed by the Korean Intellectual Property Office (KIPO), which aligns with international standards.
Key features relevant to KR100665919 include:
- Patent Term: 20 years from priority date, usually extending protection for at least 12-15 years post-approval.
- Patent Examination: Stringent examination standards for novelty and inventive step, especially in chemicals/pharmaceuticals.
Major Competitors and Patent Families
The patent landscape involves:
- Infringement Risks: Key local and international competitors may hold patent families covering similar compounds or methods.
- Patent Thickets: Multiple patents around the same chemical class or therapeutic use, creating, in effect, patent thickets complicating freedom-to-operate.
Global Patent Landscape
- Similar patents might exist in major jurisdictions: US (e.g., US patents), Europe (EPO), Japan.
- International patent applications (via PCT) could extend protection or provide insights into patent families and expiration timelines.
Patent Lifecycle and Litigation
- Older patents, like KR100665919, face expiration or nearing expiry, opening opportunities for generic development.
- Patent challenges (e.g., patent oppositions or litigation) may occur if competitors contest validity or scope.
Strategic Implications for Stakeholders
For Patent Holders
- Protection Strength: Highlighting specific structural claims and therapeutic methods strengthens enforceability.
- Expansion Strategy: Filing continuation or divisional applications could extend protection.
- Lifecycle Management: Monitoring expiration dates to plan generic manufacturing or licensing.
For Competitors
- Design-around Opportunities: Analyzing claims to develop similar but non-infringing compounds.
- Landscape Navigation: Investigating overlapping patents for freedom-to-operate assessments.
For Researchers and Developers
- Innovation Opportunities: Identifying unclaimed therapeutic uses or formulations inspired by the patent.
- Collaboration Potential: Licensing from patent holders can accelerate product development.
Conclusion
South Korea patent KR100665919 provides a significant protective scope over a specific chemical entity or therapeutic method established by the filing timeframe. Its claims likely encompass a compound, its pharmaceutical uses, and potentially manufacturing processes, with scope calibrated for novelty and inventive step.
The patent landscape underscores the importance of strategic prosecution, vigilant monitoring for patent expiry, and careful navigation of overlapping patents to ensure market freedom. For innovator entities, detailed technical and legal analysis remains vital for securing competitive advantage and capitalizing on the patent’s enforceability.
