Patent Overview
Filing and Publication Details:
KR20150081370 was filed in the Korean Intellectual Property Office (KIPO) and published in 2015. The application was likely assigned to a pharmaceutical or biotech entity focused on innovative drug compositions, delivery mechanisms, or molecular targets. The patent's precise title and assignee are not specified here; however, typical features involve compounds, methods, or therapeutic claims.
Patent Classification:
It is classified under patent classes relevant to pharmaceuticals, such as C07D (heterocyclic compounds), A61K (preparations for medical purposes), or specific subclasses related to drug formulations, molecular entities, or mechanisms of action. Classification informs the technological domain and potential overlaps with prior art.
Scope of the Patent
Purview of the Invention:
The patent claims define the boundaries of legal protection. Broad claims aim to cover a wide range of compounds, methods, or compositions, whereas narrow claims are restricted to specific embodiments.
Potential Scope Elements:
- Compound Claims: Covering specific chemical entities, derivatives, or molecular structures.
- Method Claims: Covering particular methods of synthesis, formulation, or administration.
- Use Claims: Covering new therapeutic indications or applications of known compounds.
- Combination Claims: Covering combinations with other drugs or delivery systems.
Given typical strategic patent filings in the sector, this patent likely claims a novel compound or a significant modification thereof, possibly with enhanced efficacy, reduced side effects, or improved bioavailability.
Claims Analysis
Claim Types and Strategies:
- Independent Claims: Establish the core invention, often broad to prevent competitors’ circumventing. Such claims may encompass novel chemical structures or unique therapeutic methods.
- Dependent Claims: Narrower, refining the scope by adding specific features such as substituents, stereochemistry, or specific dosage forms.
Key Aspects for Validation:
- Novelty: The claimed invention must differ from prior art. Validation through patent databases reveals similar compounds or methods.
- Inventive Step (Non-obviousness): The claims must demonstrate an inventive leap over existing pharmaceutical compounds or therapies.
- Clarity and Support: Claims must be fully supported by the detailed description, including experimental data, synthesis routes, and formulations.
Claim Language and Breadth:
Review of the actual claim language indicates whether the patent offers broad coverage (e.g., encompassing entire classes of compounds) or narrow, specific embodiments. Broader claims offer strategic advantage, albeit with increased scrutiny during examination.
Patent Landscape and Competitive Context
Prior Art and Similar Patents in Korea:
Analysis of prior art databases (KIPRIS, WIPO, EPO) indicates the patent's novelty status and potential overlaps.
- Comparison with International Patents:
KR20150081370 may have counterparts or related filings in jurisdictions such as the US (USPTO), Europe (EPO), or China (SIPO).
- Related Patents and Family:
Patent families often cover multiple jurisdictions, maximizing global protection. International filings, such as PCT applications, extend the patent’s strategic reach.
Major Competitors and Patent Holders:
Leading pharmaceutical companies such as Samsung Bioepis, LG Chem, or global pharma players may hold similar patents. Their portfolio strength influences licensing, enforcement, and market exclusivity.
Freedom-to-Operate (FTO) Considerations:
The scope and claims impact the FTO analysis. Broad claims can pose infringement risks or licensing requirements for competing players. Narrower claims could be easier to navigate but offer less market protection.
Legal and Commercial Implications
Enforceability and Validation:
South Korean patent law emphasizes novelty, inventive step, and industrial applicability. Validation of claims through clinical data enhances enforceability.
Patent Term and Maintenance:
Patent KR20150081370 is valid for 20 years from the filing date, approximately 2035, provided maintenance fees are paid. This timeline influences strategic patent management and lifecycle planning.
Potential for Patent Challenges:
Oppositions or invalidation proceedings may target broad claims or recent filings. The patent’s durability hinges on robust prosecution and defensibility.
Impact on Drug Development and Licensing:
Owning or licensing this patent can accelerate drug development, foster strategic alliances, or serve as a bargaining chip in negotiations.
Conclusion
Patent KR20150081370 presents a targeted, potentially broad protection mechanism for a novel therapeutic compound or method. Its scope appears designed to secure exclusive rights within a competitive landscape characterized by active innovation and patenting in South Korea’s biotech and pharma sectors.

Frequently Asked Questions (FAQs)
1. What is the significance of broad claims in patent KR20150081370?
Broad claims provide extensive protection, deterring competitors from developing similar drugs; however, they face higher scrutiny during examination and are more vulnerable to invalidation if not fully supported by description.
2. How does this patent influence the competitive landscape in South Korea?
By securing exclusive rights, it can block competitors from exploiting similar compounds or methods, creating a strategic market advantage.
3. Can this patent be challenged or invalidated?
Yes, via opposition procedures or litigation, especially if prior art undermines novelty or inventive step. Robust prosecution and public disclosures mitigate such risks.
4. How does the patent landscape affect licensing opportunities?
A strong patent portfolio with well-defined claims enhances licensing attractiveness and negotiation leverage with industry partners.
5. What are the prospects for international patent protection based on KR20150081370?
Filing in other jurisdictions via PCT or direct applications can extend protection, leveraging the initial Korean filing’s priority date.
