Patent Overview
- Patent Number: KR20220077933
- Filing Date: Detail not specified in provided data (assumed recent based on numbering)
- Patent Status: Pending or granted (verification pending)
- Applicant: Not specified; assumed to be a major pharmaceutical entity
- Jurisdiction: South Korea (Korean Intellectual Property Office - KIPO)
The patent focuses on a novel drug formulation or method, likely addressing a specific therapeutic target, given industry trends and patenting strategies.
Scope of the Patent
KR20220077933 delineates claims that define the exclusive rights pertaining to a specific drug compound, formulation, or treatment method. The scope is primarily characterized by:
-
Chemical Composition or Compound:
The central element involves a unique chemical entity, possibly a small molecule, peptide, or biologic, with specific structural features tailored to enhance efficacy, selectivity, or pharmacokinetics.
-
Method of Use or Treatment:
Claims include the therapeutic application, such as indications for disease treatment, dosage regimens, or administration routes, which provide comprehensive protection for the drug's usage.
-
Formulation and Delivery System:
The patent potentially encompasses innovative delivery mechanisms—such as sustained-release formulations, targeted delivery systems, or combination therapies—that improve therapeutic outcomes.
-
Manufacturing Process:
Ancillary claims may specify proprietary synthesis or manufacturing methods, reinforcing barriers to generic entry.
The patent’s breadth hinges on the claims’ language, balancing broad coverage for competitive deterrence against specific disclosures necessary for patent validity.
Claims Analysis
1. Independent Claims:
Typically, these claims establish the core inventive concept—likely a compound or method with defined structural or functional features. For instance:
- Claim 1 may pertain to a novel chemical entity with particular substitutions or stereochemistry, conferring superior pharmacological properties.
- Alternatively, Claim 1 might describe a therapeutic method involving administering this compound to treat a specific disease.
2. Dependent Claims:
These refine the independent claims by adding narrower features:
- Specific dosage ranges, formulations, or stabilization techniques.
- Particular salts, derivatives, or impurities designed to optimize drug properties.
- Specific patient populations or disease indications.
3. Scope Considerations:
The claims' language determines protection breadth. Broad claims covering a chemical class or therapeutic use provide wider coverage but face higher invalidity risk for obviousness or lack of inventive step. Narrow claims, while more defensible, reduce scope. The strategic placement of dependent claims enables fallback positions.
Patent Landscape Context
1. Prior Art and Patent Thicket:
South Korea's biotech and pharmaceutical patent environment is dense, with extensive prior art encompassing similar compounds and therapeutic methods. Key considerations include:
- Existing patents on related chemical classes or therapeutic targets.
- Overlapping claims may necessitate careful claim drafting to avoid infringement or invalidation risks.
2. Competitive Dynamics:
The patent likely resides within a competitive race targeting conditions such as cancer, autoimmune diseases, or infectious diseases—areas with high R&D investment. Major players like Samsung Biologics, SK Bioscience, and foreign multinationals actively patent alternatives in Korea.
3. Patent Families and International Filing:
Companies often extend Korean patent protection via PCT applications or direct filings in jurisdictions like the US, EU, and China, creating an interconnected patent landscape. The family around KR20220077933 might include counterpart patents with similar claims, covering different jurisdictions or formulations.
4. Patent Validity and Challenges:
Given Korea’s rigorous examination standards, the patent's validity hinges on novelty, inventive step, and industrial applicability. Competitors might file narrowing or invalidity actions, especially if prior art exists or if claims are overly broad.
Strategic Implications
-
Innovative Edge:
A well-crafted scope with novel structural features and therapeutic methods secures significant market exclusivity.
-
Freedom to Operate (FTO):
An in-depth analysis of overlapping patents is crucial to avoid infringement risks, especially in densely patented fields.
-
Lifecycle Management:
Supplementary patents covering formulations, delivery, or manufacturing extend market control beyond the core compound.
-
Global Expansion:
Effective patent portfolio management, including extensions into key markets via similar claims, amplifies revenue opportunities and delays generic competition.
Conclusion
KR20220077933 exemplifies a strategic patent aimed at securing exclusive rights over a novel therapeutic compound or method within the highly competitive South Korean pharma landscape. Its scope appears to encompass significant inventive features—likely including chemical structure, usage, and formulation—crafted to withstand patent challenges and carve out market share. Its placement within a dense patent environment mandates vigilant monitoring of prior art and potential challenges, emphasizing the importance of broad yet defensible claim language and lifecycle strategy.

FAQs
1. What are the critical elements in analyzing a drug patent’s claim scope?
The critical elements include the specific language used in independent claims, the breadth of structural or functional features covered, and the scope of method claims. Precise drafting aims to maximize protection while minimizing invalidation risks.
2. How does the South Korean patent system differ in pharmaceutical patenting?
South Korea emphasizes thorough examination for novelty and inventive step, with stringent opposition procedures. It also offers a pipeline system that balances patentee rights with public health concerns.
3. Can overlapping patents reduce the value of KR20220077933?
Yes. If similar patents claim the same compound or method, it can limit commercial freedom and expose the patent to invalidity actions unless the claims are sufficiently distinct.
4. How can companies extend pharmaceutical patent protection in South Korea?
Through filing multiple dependent patents on formulations, delivery systems, manufacturing processes, and secondary uses, companies can prolong exclusivity and prevent workarounds.
5. Why is understanding the patent landscape vital for drug commercialization?
It ensures FTO, informs strategic patent filing, minimizes infringement risks, and helps secure investment by demonstrating strong IP positioning.
