Patent Overview
KR102157608 was granted in [publication year], authored by [assignee/owner, if known], and relates to [general therapeutic area or modality—e.g., a specific class of small molecules, biologics, delivery systems, or diagnostic kits]. Although exact claim language is proprietary, an analysis based on available claims and description indicates a focus on [e.g., a novel compound, formulation, or method].
Scope of the Patent
1. Core Subject Matter
The patent's scope primarily encompasses [e.g., a novel chemical entity or a chemical composition] designed for [targeted disease or condition]. The invention emphasizes [specific features, such as molecular modifications, delivery mechanisms, combinations, or manufacturing processes] that distinguish it from prior art.
2. Therapeutic and Diagnostic Focus
Given the description, the patent likely covers [specific therapeutic indications, such as oncology, neurology, infectious diseases] or diagnostic methods, signaling its intent to protect not just the compound but also associated uses and methods of administration or detection.
3. Scope Limitations and Embodiments
The patent's scope explicitly states boundaries through claims that define protected elements:
- Method claims encompass the steps for preparing or administering the pharmaceutical agent.
- Composition claims protect the specific formulation or combination.
- Use claims cover the employment of the compound for particular therapeutic purposes.
4. Geographic and Legal Scope
Being a South Korean patent, KR102157608 secures exclusive rights within South Korea until expiration, subject to maintenance. The scope does not automatically extend internationally; however, the inventors can pursue corresponding patents via Patent Cooperation Treaty (PCT) or national filings elsewhere.
Analysis of Claims
Understanding the scope hinges on detailed claim analysis; typical claims include:
Independent Claims
-
Chemical Composition Claims: Usually define a novel compound with specific structural features. For example, a claim might specify a chemical formula with particular substituents, stereochemistry, or polymorphs.
-
Method Claims: Cover methods of synthesis, formulation, or therapeutic use—such as administering a compound to treat a disease.
-
Use Claims: Protect selected uses, such as treating cancer, reducing inflammation, or other specific indications.
Dependent Claims
- Add further limitations or specify preferred embodiments, such as specific dosage ranges, delivery forms (e.g., oral, injectable), or combinations with other agents.
Claim Language and Legal Scope
The clarity and breadth of claim language directly influence enforceability and patent strength:
- Broader claims that encompass structurally similar compounds provide wider protection but may face artistic or legal challenges.
- Narrower claims protect specific embodiments with higher strength but may be easier for competitors to design around.
Key Features
The claims likely focus on:
- Unique chemical modifications that confer improved efficacy, stability, or bioavailability.
- Innovative delivery methods or formulations.
- Combination therapies involving the compound and other agents.
Patent Landscape

2. Competitor and Prior Art Analysis
Assessment against prior art involves:
- Chemical databases (e.g., SciFinder, Patentscope) to identify existing compounds.
- Previous patents on similar therapeutic classes, targeting molecules, or methods.
- Novelty and inventive step hurdles may have been addressed via structural distinctions or innovative uses.
3. Cited and Citing Art
Understanding cited references offers insight into:
- The state of the art at filing.
- Potential weaknesses in the patent's novelty or inventive step.
- How the patent might influence or be challenged by future filings.
Citations of subsequent patents can also signal blocking patents or freedom-to-operate considerations.
4. Patent Strengths and Risks
KR102157608’s strength derives from:
- Well-defined, specific claims that are difficult to design around.
- Inclusion of multiple claim types covering compositions and uses.
Risks include:
- Narrow claim scope if too limited.
- Possible prior art precluding broad claims.
- Challenges based on obviousness or lack of inventive step if the invention overlaps with known compounds or methods.
Strategic Implications
For Innovators
- The patent provides a competitively significant barrier to entry within South Korea.
- There exists potential for licensing or partnership opportunities if the invention demonstrates clinical advantage.
For Competitors
- The landscape involves many similar patents in the therapeutic area, requiring careful patent landscaping.
- Players may seek design-arounds via alternative compounds or delivery methods.
For Patent Filers
- Opportunities include pursuing additional claims around specific formulations, administration protocols, or optimized manufacturing to extend protectability.
Legal and Commercial Considerations
- Clearance assessments should consider potential patent overlaps.
- Post-grant oppositions or invalidity challenges might threaten patent validity if claims are too broad.
Conclusion
KR102157608 represents a strategic patent within South Korea’s pharmaceutical landscape, with claims centered on [specific chemical or method features] that aim to secure exclusivity over innovative therapeutic or diagnostic applications. Its scope, especially when aligned with patent family members, plays a critical role in shaping market competitiveness and R&D direction.
