The patent appears to fall within pharmaceutical compositions, likely involving a novel compound, formulation, or therapeutic method aimed at addressing unmet medical needs, such as targeted treatment, improved bioavailability, or reduced side effects.
The following sections dissect the core aspects of the patent, focusing on the claims, scope, and related patent landscape.
Scope and Claims Analysis
Types of Claims
The patent's claims can typically be categorized into:
- Independent Claims: Define the broadest scope—often centered on the composition, compound, or method.
- Dependent Claims: Add specific limitations, such as particular chemical structures, dosages, or treatment protocols.
Core Claims Overview
While the actual claims are only retrievable through official document access, an analysis based on typical pharmaceutical patent structures suggests:
- Claim 1 (Independent Claim): Likely claims a novel chemical entity or a pharmaceutical composition comprising the compound, formulated for specific therapeutic use.
- Claims 2-10 (Dependent): Narrow down to specific embodiments, such as stereoisomers, salts, polymorphs, formulations, or adjunctive agents.
Claim Language and Scope
- Broadness: The primary claim probably emphasizes the molecule or composition's core structure, with explicit mention of chemical groups or pharmacological targets. The scope's breadth hinges on the chemical definition; precise chemical structure definitions generally limit scope compared to broader functional claims.
- Specificity: Narrow claims might specify doses, delivery methods (e.g., oral, injectable), or targeted diseases.
Implications for Innovation and Patentability
- The novelty of the chemical structure or therapeutic method contributes to patentability.
- Patent clarity and scope depend on the specificity of the chemical definitions, which influence both enforceability and licensing potential.
- The inclusion of polymorphs or formulations strengthens the patent by covering multiple embodiments.
Patent Landscape in South Korea
Existing Competitors and Prior Art
South Korea's pharmaceutical patent landscape is vibrant, featuring key domestic companies (e.g., Hanmi, Celltrion) and multinational pharma players. The landscape for similar drugs involves:
- Existing patents: Likely filed for related classes with overlapping claims. These may include compounds, derivatives, formulations, and delivery methods.
- Prior art: Patent searches indicate numerous filings for therapeutic agents targeting similar pathways, e.g., kinase inhibitors, monoclonal antibodies, or small molecules for targeted diseases.
Main Patent Families Related to KR20220104166

- Comparative analysis of these families helps assess freedom-to-operate (FTO) and innovation differentiation.
- Similar claims in prior art typically focus on chemical modifications, specific pharmacokinetic profiles, or targeted indications.
Legal and Patentability Considerations
- Novelty: The claimed compound must not have been disclosed previously, especially in prior art patents or scientific publications.
- Inventive Step: Demonstrating unexpected therapeutic benefits or structural modifications that are not obvious.
- Industrial Applicability: The invention must be applicable in pharmaceutical manufacturing or therapy.
Strategic Positioning
- The patent's scope, if sufficiently broad, grants significant market exclusivity.
- Narrower claims may facilitate licensing or further patent filings.
- Continuous innovation, such as patenting polymorphs or combination therapies, enhances protection.
Competitive and Innovation Landscape
South Korea’s patent environment for pharmaceuticals emphasizes:
- Biotech and innovative small molecules: Presence of high R&D activity from domestic firms.
- Target-specific patents: Emphasis on personalized medicine and targeted therapeutics.
- Patent filing trends: Growing filings for formulations, drug delivery systems, and polymorphs, indicating an innovation trend toward optimizing existing molecules.
Within this landscape, KR20220104166's value depends on:
- Its novelty status relative to prior art.
- The scope of claims covering core active ingredients.
- Its strategic positioning for licensing or commercialization.
Legal Status & Future Outlook
While specific legal status is subject to the official patent register, assuming the patent has been granted or allowed, its enforceability aligns with South Korea's robust patent enforcement system. Ongoing patent examinations in related areas might influence patent scope adjustments or challenger strategies.
Conclusion
Patent KR20220104166 represents a strategic intellectual property asset within South Korea’s competitive pharmaceutical patent landscape. Its scope—the breadth of chemical and formulation claims—determines its market value and enforceability. Given the competitive field, comprehensive patent prosecution, and potential collaborations, the patent can secure significant protection if its claims are robust and well-differentiated from prior art. Continuous monitoring of citations, legal status, and evolving innovations in related areas remains crucial for maximizing its value.
