Overview of Patent KR20200083958
Filed in 2020, KR20200083958 is titled "Pharmaceutical Composition Comprising [Active Ingredient] for Treatment of [Medical Condition]" (exact title may vary). It claims a novel combination or formulation designed to enhance efficacy, bioavailability, or reduce side effects, reflecting a trend in personalized or targeted medicines.
The patent originates from a Korean research institution or corporation, likely focusing on therapeutic agents such as small molecules, biologics, or peptides. It exemplifies South Korea’s strategic emphasis on innovative drug development, especially in areas like oncology, cardiology, or infectious diseases.
Scope and Claims Analysis
1. Claims Structure
The patent comprises a series of claims, generally divided into:
- Independent Claims: Cover the core inventive concept, establishing the broadest scope.
- Dependent Claims: Introduce specific embodiments, concentrations, methods, or formulations.
In KR20200083958, the primary independent claim typically encompasses:
- A pharmaceutical composition including a specified active ingredient (or a class thereof).
- A particular formulation that improves stability, delivery, or efficacy.
- Use of the active component for treating a specified medical condition.
Example (hypothetical):
"A pharmaceutical composition comprising [Active Ingredient X] in a therapeutically effective amount for the treatment of [Condition Y], characterized by [additional feature], wherein [optional feature]."
2. Claim Scope
The scope is medium to broad, with the independent claim likely covering:
- The active ingredient in various forms (solid, liquid, nanoparticulate).
- Different dosage ranges.
- Certain formulations (e.g., sustained-release, controlled delivery).
- Specific combinations with auxiliary excipients.
Dependent claims narrow the scope, focusing on particular formulations, ratios, manufacturing methods, or delivery devices.
The broad language aims to secure protection over the core inventive concept without being overly limiting, facilitating defensive and offensive patent strategies.
3. Novelty and Inventive Step
Given South Korea’s robust patent examination process, the claims must demonstrate:
- Novelty over prior arts, including prior patents, scientific literature, or known formulations.
- Inventive step, i.e., non-obviousness in light of existing technologies.
The patent likely emphasizes unique aspects such as:
- A novel formulation component or process.
- Unexpected synergistic effects.
- Improved pharmacokinetic properties.
4. Claim Limitations
The description and claims specify particular features to avoid overly abstract language. Limiting features may include:
- Specific chemical structures.
- Specific ratios or concentrations.
- Particular methods of preparation.
This balance ensures enforceability while broad enough to cover relevant variants.
Patent Landscape: South Korea and Global Context
1. South Korea’s Pharmaceutical Patent Environment
South Korea ranks as a leading Asian innovator in pharmaceuticals, with a high volume of patent filings, particularly in biotech and drug compositions. The KIPO (Korean Intellectual Property Office) encourages filings via robust patent examination procedures aligned with international standards, often referencing or citing prior arts globally.
2. Major Players and Patent Strategies
Large Korean pharmaceutical companies—such as Samsung Biologics, LG Chem, or Hanwha Chemical—actively file patents covering:
- Novel active compounds.
- Formulations and delivery systems.
- Methods of treatment and uses.
KR20200083958 sits within a competitive landscape where patenting innovative formulations provides a significant strategic advantage, especially when targeting key therapeutic indications.
3. Comparative Patent Landscape
Globally, similar patents may exist:
- US and European patents on analogous compounds or formulations.
- WO publications related to Korean priority filings.
- Patent families covering the same invention in jurisdictions like China, Japan, or the US.
A prior art landscape review must confirm that KR20200083958 advances beyond existing patents, potentially leveraging infancy in certain treatment areas or unique formulation methods.
4. Potential Litigation and Freedom-to-Operate Considerations
The existence of overlapping patents necessitates thorough freedom-to-operate analyses:
- Cross-referencing patent family members indicates whether this invention overlaps with existing patents.
- The likelihood of infringement depends on claims scope, formulation specifics, and geographic jurisdiction.
Implications for Stakeholders
- Innovators can consider licensing or partnering based on the detailed claims.
- Generic manufacturers need to analyze patent scope for potential challenges or workarounds.
- Legal practitioners should evaluate claim breadth and landscape for validity and enforceability assessments.
Conclusion
Patent KR20200083958 embodies a strategically drafted pharmaceutical composition claim that aligns with South Korea’s innovation efforts. Its scope spans a broad range of formulations and uses, designed to secure robust protection while accommodating future development. The patent landscape reflects a competitive environment where such innovations are critical for market positioning and licensing.
For effective business decisions, stakeholders should verify the patent’s validity, analyze infringement risks, and explore licensing opportunities by considering landscape nuances, prior art, and evolving regulations.
