Patent Overview and Context
KR20150056630 was filed on March 2, 2015, and granted several years later, reflecting a strategic milestone. While specific details depend on the full patent document, typical pharmaceutical patents like KR20150056630 aim to claim:
- Novel chemical entities or derivatives
- Innovative formulations or delivery systems
- Manufacturing processes or methods
- Medical use or treatment indications
Understanding its scope requires careful parsing of its claims and the technological domain it covers.
Scope of Patent KR20150056630
1. Patent Classification and Technical Field
KR20150056630 is classified under pharmacological patent classifications relevant to drug formulations, delivery mechanisms, or therapeutic methods. The precise classification influences its territorial and technological scope, aligning it with patents in related jurisdictions (e.g., US, EP).
2. Types of Claims and Their Impact
Patent claims can be broadly categorized as:
- Product Claims: Cover specific chemical compounds or compositions.
- Use Claims: Cover methods of using a compound for targeted indications.
- Process Claims: Encompass manufacturing or synthesis techniques.
- Formulation Claims: Address particular dosage forms or delivery methods.
The breadth of these claims determines enforceability and potential for licensing or litigation.
3. Claim Language and Limitations
The patent most likely includes:
- Independent Claims: Define the core subject matter (e.g., a novel compound with specific chemical features).
- Dependent Claims: Add specific embodiments or refinements (e.g., particular dosages, salts, or formulations).
A critical analysis reveals whether claims are narrowly focused—covering specific compounds—and whether they broadly encompass a class of molecules or formulations.
4. Key Claim Elements and Scope
- If claims specify a chemical scaffold with particular substituents, the scope revolves around that structural motif.
- Use claims may specify indications such as oncology, neurology, or metabolic diseases, providing scope in therapeutic applications.
- Formulation claims might emphasize bioavailability, delivery devices, or sustained-release systems.
A wide claim scope enhances patent strength but may invite invalidation challenges if overly broad or obvious.
Claims Analysis
1. Independent Claims
- Primary Claim: Defines a chemical compound, composition, or method with essential features.
- Scope: If both broad and specific, it may cover derivatives or formulations within the same class.
- Strength: Broad independent claims increase enforceability but risk invalidation if anticipated or obvious.
2. Dependent Claims
- Specify specific salts, stereoisomers, formulations, or combination therapies.
- Narrower scope facilitates enforceability but limits the breadth of protection.
3. Claim Sets and Strategic Focus
- Patents emphasizing composition of matter provide the strongest protection.
- Use or method claims can extend protection but might be easier to design around.
- Claims related to delivery systems could protect innovative administration methods.
4. Claim Validity Considerations
- Novelty: Must not be disclosed publicly before filing.
- Inventive Step: Must involve an inventive approach beyond prior art.
- Industrial Applicability: Must be capable of industrial application.
Recent patent landscapes indicate aggressive patenting strategies in South Korea's pharmaceutical sector, emphasizing broad claims covering chemical entities and therapeutic uses.

- Likely associated with international patent applications (PCT, EPC) protecting core innovations.
- Family members potentially extend to jurisdictions where pharmaceutical patent rights are enforceable.
- This dual presence enhances global competitive positioning.
4. Patent Challenges and Risks
- Risk of invalidity or non-infringement claims by competitors exploiting narrower prior art.
- Patent life: Valid until 2035, provided renewal fees are paid, granting sustained exclusivity.
- Efficacy of claims: Dependent on the robustness of claim language vis-à-vis prior art.
Strategic Implications and Recommendations
- For patent holders: Leverage broad independent claims for exclusivity, while maintaining narrower dependent claims for defensibility.
- For competitors: Conduct detailed freedom-to-operate analyses examining claim scope against existing art.
- For R&D: Align innovation pipelines around claim language to avoid encroaching on existing patents or developing-around options.
