Overview of Patent KR101260554
- Application Date: Likely filed around 2011-2012 (based on KIPO publication data).
- Grant Date: Approximately 2013, considering Korean patent processing timelines.
- Patent Type: Utility patent, focusing on a novel compound, formulation, or use.
- Jurisdiction: South Korea, governed by the Korean Intellectual Property Office (KIPO).
- Expiration: Typically 20 years from filing, subject to maintenance fees and potential patent term adjustments.
While precise details of the original application are not provided here, the patent broadly covers novel chemical entities or pharmaceutical formulations with specific claims that confer exclusive rights.
Scope and Claims Analysis
1. Primary Claims Structure
South Korean patents in pharmaceuticals generally feature a hierarchy of claims:
- Independent Claims: Define the broadest scope, often covering a novel compound, composition, or method of use.
- Dependent Claims: Specific embodiments refining independent claims through additional features or limitations.
KR101260554's claims likely focus on:
- A chemical compound or class thereof with particular structural features.
- A pharmaceutical composition containing the claimed compound.
- A therapeutic use or method of treatment involving the compound or composition (e.g., targeting a specific disease like cancer, diabetes, etc.).
2. Scope of the Claims
The scope of the claims directly impacts the patent's enforceability. Based on standard principles and the patent landscape, the claims probably encompass:
- A novel chemical entity with a unique structural framework designed for improved efficacy or reduced side effects.
- Methods of synthesis for the compound, assuming the patent includes process claims.
- Specific formulations such as controlled-release or targeted delivery systems.
- Therapeutic methods involving administration of the compound for particular indications.
The claims likely aim to balance broad protection—covering a wide class of compounds or uses—with specific limitations to prevent invalidation.
3. Claim Limitations and Breadth
- Structural limitations: Usually specify certain substituents or rings (e.g., heterocyclic groups, functional groups).
- Use limitations: Could target specific diseases or pathways, e.g., kinase inhibitors, receptor modulators.
- Formulation claims: Might specify carriers, delivery methods, or dosage forms.
Such specific language aims to maximize exclusivity while avoiding overlaps with prior art.
Patent Landscape Context
1. Prior Art and Novelty
South Korean patent prosecution rigorously examines novelty and inventive step, especially in pharmaceuticals. KR101260554’s patentability likely hinges on:
- Unique structural aspects distinguishing it from existing compounds.
- Unexpected efficacy or reduced toxicity supporting inventive step.
Patent examiners would have scrutinized prior art in global databases, including WIPO, EPO, and USPTO patent collections, to ensure its novelty.
2. Competitive Patent Families
In the pharmaceutical space, patents often form part of complex patent families with equivalents filed internationally. Key considerations include:
- Priority filings: The original filing might have priority in multiple jurisdictions, affecting global patent strategies.
- Related patents: Subsequent filings could include polymorphs, formulations, or method claims, expanding patent coverage.
3. Freedom to Operate and Infringement Risks
The patent's scope must be compared with competing patents to assess infringement risks:
- Broad claims: If expansive, could create barriers to third-party development.
- Narrow claims: May require careful validation to avoid infringement, though provide more freedom in other areas.
Implications for Stakeholders
Pharmaceutical Developers
The patent’s scope indicates protected chemical entities and uses, guiding research to avoid infringement or focus on novel modifications.
Legal and Patent Strategists
Understanding claim breadth assists in evaluating patent strength and potential for licensing, partnerships, or challenges.
Investors and Market Analysts

-
Patent Landscape is Competitive and Global: The patent’s value is maximized when integrated into a broader portfolio, considering international counterparts to secure global market rights.
-
Strategic Landscape Navigation is Crucial: Legal positioning and ongoing patent prosecution should prioritize defending the scope against challenges and covering follow-up innovations.
-
Market and Regulatory Integration Enhances Value: Patent protection must align with regulatory approval processes to optimize commercial exclusivity.
FAQs
1. What is the typical scope of claims in South Korean pharmaceutical patents like KR101260554?
Claims typically cover specific chemical compounds, their pharmaceutical compositions, and therapeutic uses. They range from broad to narrow, emphasizing novel structural features, formulations, or treatment methods unique to the invention.
2. How does KR101260554 compare to international patents in similar therapeutic areas?
While specific structural or use claims define its uniqueness, comparative analysis reveals whether the patent family extends protection globally. Such patents often have counterparts filed under PCT or in regional patent offices to maximize coverage.
3. Can competitors develop similar drugs without infringing on KR101260554?
Infringement depends on claim scope and design-around strategies. Narrow claims may be easier to circumvent through chemical modifications, whereas broad claims require sophisticated design work to avoid infringement.
4. What strategies should patent holders employ to strengthen their patent portfolio in South Korea?
Filing secondary patents covering polymorphs, formulations, dosing regimens, or new uses enhances protection. Continuing prosecution to amend claims and filing internationally via PCT also reinforce legal standing.
5. How does licensing or litigation landscape influence the value of KR101260554?
Active licensing or litigation indicates market relevance. A strong patent with enforceable claims can attract licensing deals, while legal challenges may threaten patent validity, impacting valuation.
