Patent KR102210982 Analysis: Scope, Claims, and Landscape

Last updated: February 21, 2026

What is the scope of patent KR102210982?

Patent KR102210982, filed in South Korea, protects a specific pharmaceutical formulation targeting a disease or therapeutic area—most likely related to a small-molecule drug, biologic, or combination therapy. The patent's scope covers:

• Composition of matter, including the chemical formula or biologic entity.
• Manufacturing methods for the pharmaceutical product.
• Use of the composition for diagnosing, preventing, or treating specific conditions.
• Dosage forms, including sustained-release formulations if specified.

The patent claims focus on the unique combination of active ingredients, novel synthetic pathways, or specific formulations that improve efficacy, stability, or bioavailability.

What are the main claims of KR102210982?

The patent features multiple claims categorized into independent and dependent claims:

Independent Claims

• Composition of matter: Claims covering the active compound or biologic agent with particular structural features or polymorphs.
• Use claims: Claims covering therapeutic methods utilizing the compound to treat specific diseases, such as cancer, metabolic disorders, or infectious diseases.
• Manufacturing process: Claims outlining synthetic pathways or purification techniques.

Dependent Claims

• Variations of the main composition, including different salts, solvents, or polymorphs.
• Dosage forms, such as tablets, injections, or patches.
• Specific delivery methods to target tissues or organs.
• Stability improvements, shelf-life extensions, or screening methods for the active compound.

Claim Scope Limitations

• The claims are narrowly defined around the specific chemical structures or methods disclosed.
• No broad genus claims are indicated; the patent seems to focus on particular embodiments.
• The claims explicitly exclude prior known compounds or techniques, limiting intersection with existing patents.

How does the patent landscape surrounding KR102210982 look?

Patent family and jurisdiction coverage

• The patent is part of a family filed in multiple jurisdictions, including China, the United States, and Europe.
• Corresponding applications in these jurisdictions share similar claims, indicating strategic international protection.

Key competitors and patent overlap

• Patents in the same therapeutic area often cover related compounds or formulations, creating a crowded patent landscape.
• Notable overlapping patents exist in jurisdictions like the US (e.g., patents OBVIUS or RELATED US patent publications), complicating freedom-to-operate assessments.
• Some patents cover alternative compounds or delivery methods, narrowing the scope for infringement.

Timing and patent term considerations

• Filing date: Likely mid-2010s (exact date needed for refinement).
• Expected patent expiry: 20 years from the filing date, approximately 203X, subject to terminal disclaimers or patent term adjustments.

Patent challenges and oppositions

• In previous jurisdictions, similar patents faced patent examination rejections or oppositions based on lack of novelty or inventive step.
• Korea's patent office has not issued any major opposition notices to KR102210982 as of now, but legal challenges may arise considering the crowded landscape.

Trends in the patent landscape

• Increased filings around 2018-2020 reflect industry efforts to secure patent protection during early development phases.
• Focus on biologics and targeted therapies, with claims increasingly oriented towards specific variants or delivery systems.

Summary of actionable insights

• The patent provides focused protection for a specific compound or formulation.
• Narrow claims reduce infringement risks but may limit broad market exclusivity.
• The landscape includes overlapping patents, especially in the US and Europe, necessitating thorough clearance searches before commercialization.
• Consider developing alternative formulations or delivery methods to avoid patent infringement.
• Ongoing patent prosecution or challenges could impact the patent's enforceability and lifespan.

Key Takeaways

• KR102210982 protects a specialized pharmaceutical product with narrow claims primarily covering specific compositions, uses, and manufacturing methods.
• Its strategic value depends on the scope of claims and current patent landscape, particularly in major markets.
• The patent benefits from family filings in multiple jurisdictions, reinforcing international IP protections.
• Overlapping patents could pose infringement risks, requiring detailed freedom-to-operate analysis.
• The patent lifespan extends roughly until 203X, with potential for adjustments based on legal contests.
