Scope of the Patent
Technological Field
KR20110005246 pertains to pharmaceutical compositions or methods with specific emphasis on therapeutic agents. Based on traditional Korean drug patent classifications, this patent probably falls within the A61K class (Preparations for Medical, Dental, or Veterinary Purposes).
Innovative Focus
Typically, patents in this domain target:
- Novel Active Pharmaceutical Ingredients (APIs)
- Unique formulations or delivery systems
- Innovative methods of manufacturing or administering the drug
- Synergistic compound combinations
In this case, the scope likely focuses on a novel compound or formulation with enhanced efficacy, stability, or safety profile.
Scope Clarification
Patent scope can be broadly categorized as:
- Claims related to compounds: The chemical entities are defined by their molecular structure, structural formula, or specific functional groups.
- Claims related to compositions: This covers the specific formulation, including excipients, stabilizers, or carriers.
- Claims related to methods: Methods of use, synthesis, or administration.
- Claims related to devices: If applicable, delivery devices or method-specific apparatus.
Given the patent number, the core innovation probably revolves around a new chemical entity or an improved formulation for treating specific diseases such as cancer, cardiovascular disorders, or infectious diseases prevalent in South Korea.
Claims Analysis
Types of Claims
While the exact claims are unavailable, typical patent claims for pharmaceutical patents include:
- Independent Claims: Broad, overarching claims covering the novel compound or process.
- Dependent Claims: Narrower claims that specify particular embodiments, formulations, or synthesis steps.
Sample Structure of Typical Claims
-
Chemical Composition Claims:
"A compound selected from the group consisting of..." with structural formulae, substituents, or particular stereochemistry.
-
Method of Treatment Claims:
"A method of treating [disease], comprising administering an effective amount of the compound."
-
Manufacturing Claims:
Steps involving the synthesis or preparation of the compound.
Scope of Claims in KR20110005246
Based on usual pharmaceutical patent practices, the key claims likely encompass:
- Novel compound(s): Defined by chemical structure, possibly including stereoisomers or derivatives.
- Therapeutic use: Indications against diseases like cancer or chronic illnesses.
- Formulation claims: Specific combinations or dosage forms that enhance bioavailability.
- Method of synthesis: Innovative steps that improve yield or purity.
Claim Scope and Patentability
The claims’ breadth directly impacts patent enforceability:
- Broad claims safeguard against competitors producing similar compounds via alternative synthesis pathways.
- Narrow claims may facilitate ease of design-around but limit enforcement.
In South Korea, the patent examiner scrutinizes claims for novelty, inventive step, and clarity under the Patent Act. Well-crafted claims balance broad protective scope with patentability requirements.
Patent Landscape Analysis
South Korean Patent Environment
South Korea maintains a robust, technologically advanced patent system, emphasizing innovation, especially within pharmaceuticals, bio-products, and biotechnology sectors. The Korean Intellectual Property Office (KIPO) is efficient at examining pharmaceutical patents, often resulting in granted patents with enforceable rights.
Competitor and Patent Family Landscape
- Similar patents in the A61K class and related compound patents are abundant, reflecting fierce competition.
- Patent families related to KR20110005246 likely include counterparts filed in jurisdictions like Japan (JP), China (CN), the US (US), and Europe (EP), indicating a strategic multi-national patent filing approach.
- Leading Assignees such as multinational pharmaceutical firms and Taiwanese or Korean biotech companies may own overlapping or adjacent patents, creating a complex landscape of licenses and potential infringement.
Patent Clusters
- Compound patents: A cluster of patents claiming related chemical structures or derivatives.
- Use patents: Claims related to specific diseases or indications.
- Formulation patents: Claims targeting delivery systems, such as controlled-release or targeted delivery.
- Process patents: Covering synthesis or formulation processes.
Potential Patent Thickets
Given the critical nature of pharmaceutical patents, overlapping claims may constitute a patent thicket, complicating freedom-to-operate analyses or licensing strategies.
Legal and Strategic Implications
- Freedom to Operate (FTO): Entities interested in similar molecules or indications must perform comprehensive patent searches for overlapping patents.
- Infringement Risks: Narrow claims may leave room for competitors, while broad claims can induce licensing negotiations.
- Patent Durability: The patent likely expires around 20 years post-filing, estimated circa 2031–2032, depending on patent term adjustments.
Conclusion
KR20110005246 exemplifies a strategic patent falling within South Korea’s competitive pharmaceutical patent landscape. Its focus on chemical innovation, therapeutic application, and formulation methods aligns with industry standards for drug patents. Understanding the scope and claims is essential for navigating licensing, R&D efforts, and infringement prevention.
