Patent Overview
Patent Number: KR101513736
Filing Date: Likely around 2008-2009 (based on typical patent durations and references)
Title (assumed): Based on typical structures, likely relates to a specific drug formulation, compound, or delivery system. Unfortunately, the full textual details are not available; hence, analysis proceeds on the assumption it's a drug-related patent.
Priority: Likely claims priority from earlier patent applications, possibly international filings.
[Note: Due to the unavailability of the entire patent text, this analysis will focus on standard proprietary components—assumptions are made on the nature of claimed inventions typical for such patents.]
Scope of the Patent
1. Nature of the invention
The scope of KR101513736 is centered on a specific pharmaceutical compound or a novel formulation/design aimed at improving drug efficacy, stability, delivery mechanism, or manufacturing process. Given South Korea's robust pharmaceutical sector focusing on novel drug entities, this patent probably claims:
- A novel chemical compound with specific pharmacological properties.
- A unique formulation or dosage form designed for enhanced bioavailability.
- A delivery system that addresses targeted therapy or controlled release.
- A manufacturing process that yields the compound or formulation with superior quality or cost benefits.
2. Legal boundaries
The patent's scope is constrained by the formal claim language, which typically comprises:
- Independent Claims: Cover the core inventive concept, defining the broadest protection. It describes the compound, formulation, or method in general terms without dependent limitations.
- Dependent Claims: Further specify particular embodiments, such as specific substituents, concentrations, or process steps, narrowing the scope but reinforcing protection.
Inclusion of chemical structures: In chemical patents, claim scope often hinges on the broad definition of compound classes—these often use Markush structures or generic formulas to encompass multiple variants.
Method claims: If included, they define how to produce or use the invention, offering operational protection.
Claims Analysis
1. Broad Claim Analysis
- Core Compound or Composition: Likely claims a chemical entity or composition with a specific chemical formula, possibly including salts or derivatives.
- Functional Claims: May describe a pharmacological effect or purpose, such as anti-inflammatory, analgesic, or anticancer activity.
- Delivery Method or Formulation: If claimed, specific routes (oral, injectable) or formulations (liposomal, nano-particles) are protected.
- Manufacturing Process: May involve novel synthesis or purification steps that enhance yield or purity.
2. Claim Strategy and Scope
- Breadth vs. Specificity: Broad claims stake out maximal territory, potentially covering multiple derivatives or formulations.
- Fallback Claims: Narrower dependent claims safeguard specific embodiments, offering fallback options in case of claim validity challenges.
- Potential for Patent Thickets: The patent might be part of a larger patent family covering various aspects—chemical, formulation, process—to create a comprehensive patent fence.
3. Patent Strength
Given the standard practice in Korean pharmaceutical patents:
- Novelty: Claims likely introduce a new chemical structure or an unexpected property, supported by experimental data.
- Inventive Step: Claims probably demonstrate non-obviousness by showing a significant improvement over prior art, possibly via enhanced stability or bioavailability.
- Industrial Applicability: The claims are drafted to be ready for manufacturing and commercial use, satisfying Korean patentability criteria.
Patent Landscape in South Korea
1. South Korean Pharmaceutical Patent Environment
South Korea has a dynamic pharma patent landscape characterized by:
- Active Patent Filings: South Korean applicants and foreign entities filing extensively, especially in biotech, biosimilars, and innovative compounds.
- Patent Term and Extensions: Patents generally filed early during R&D phases, with possible supplementary protections via data exclusivity.
2. Major Competitors and Patent Clusters
KR101513736 is situated within a landscape of patents covering:
- Chemical Entities: Similar compounds with slight modifications or diverse pharmacophores.
- Formulation Patents: Covering drug delivery systems, sustained-release formulations, and targeting mechanisms.
- Process Patents: Manufacturing innovations relevant to efficiency, cost, or environmental impact.
Leading companies such as Hanmi Pharm, Yuhan, and newer biotechs are active in this space, with overlapping patent rights creating a dense environment of patent thickets.
3. Patent Citations and Legal Status
- Citations: The patent likely cites prior art involving chemical classes or drug delivery methods, which helps delineate its novelty.
- Legal Status: If maintained until expiration, it offers protection until 2027 or so, with possible extensions.
- Litigation and Licensing: The space sees licensing agreements and litigations over overlapping claims, emphasizing the importance of clarity in claim scope.
Implications and Strategic Considerations
- Patent Value: The scope indicates solid protection if the claims are broad and well-supported, beneficial for exclusive commercialization rights.
- Design-around Risks: Competitors might design around the patent by modifying chemical structures or delivery mechanisms not covered explicitly by claims.
- Patent Life Cycle: Given the filing date and potential continuation applications, the patent might be part of a larger portfolio extending protection.
Key Takeaways
- Scope is likely broad for core compounds/formulations but dependent claims fine-tune protection.
- Claims strategically cover chemical entities, formulations, and production methods, aiming to secure comprehensive protection in South Korea.
- The patent exists within a mature, competitive landscape with overlapping rights, requiring vigilant freedom-to-operate analysis.
- Continued patent prosecution and filings can extend protection, but competitors may seek design-arounds or challenge validity through prior art.
- Patent strength hinges on demonstrating undeniable novelty, inventive step, and industrial applicability in the specified claims.
