Overview of Patent KR20180088750
Filed in 2018, Korean Patent KR20180088750 was published on August 16, 2018. Its inventors are associated with a pharmaceutical entity focused on therapeutic compositions or drug delivery systems. While the exact patent title is not specified here, its content suggests a focus on particularly formulated drug compositions, delivery methods, or formulations intended to improve efficacy, stability, or bioavailability.
Scope of the Patent
The scope of KR20180088750 hinges upon its claims, which define the legal boundaries of the patent rights. Analyzing the scope involves understanding its core inventive concept, how broadly the claims are drafted, and potential for infringement or licensing.
1. Geographical Scope
KR20180088750 is limited to South Korea’s jurisdiction; however, its claims can influence subsequent filings in other jurisdictions through priority filings. The patent’s enforceability applies strictly within South Korea.
2. Technical Scope
Based on typical pharmaceutical patent conventions, the scope potentially encompasses:
- Specific drug formulations, such as combinations of active ingredients, excipients, or delivery systems.
- Novel methods of preparing or administering drugs.
- Improved stability, bioavailability, or reduced side effects of established drugs.
- Manufacturing processes for pharmaceuticals.
3. Legal Scope
The claims define the legal breadth, with independent claims covering the substantive inventive features, and dependent claims providing narrower embodiments. The scope’s breadth directly impacts licensing opportunities and patent infringement risks.
Claims Analysis
A comprehensive understanding requires dissecting the patent’s claims, generally divided into independent and dependent claims.
1. Independent Claims
Typically, independent claims establish the core inventive concept. For KR20180088750, the likely independent claim covers:
- A pharmaceutical composition comprising specific active agents in a defined ratio or form.
- A unique delivery system designed to enhance bioavailability.
- A process for manufacturing the composition with specific conditions.
Example (Hypothetical): “An oral pharmaceutical composition comprising active ingredient A and B in ratios of X:Y, encapsulated within a sustained-release matrix, wherein the composition exhibits improved bioavailability compared to prior art.”
This focus indicates the patent aims to protect not just the composition but also the method of making or administering it.
2. Dependent Claims
Dependent claims refine the inventive scope by adding limitations, such as:
- Specific excipients or stabilizers used.
- Particular preparation temperatures or times.
- Alternative formulations or dosage forms.
Fortifying the patent’s scope, they also delineate alternate embodiments or preferred embodiments, providing fallback positions if core claims are challenged.
3. Claims’ Breadth and Patentability
The scope’s breadth may be characterized as:
- Narrow: Focused on a specific compound or formulation, offering robust protection but limited in scope.
- Broad: Encompasses a wide class of formulations or methods, presenting higher infringement risks but facing greater scrutiny for novelty and inventive step.
South Korean patent practice emphasizes clarity and specificity in claims, with an increasing trend toward broader scope for pharmaceuticals, as long as novelty, inventive step, and industrial applicability are demonstrated.
Patent Landscape for South Korea: Contextualizing KR20180088750
South Korea’s patent environment supports a vibrant pharmaceutical industry, underpinned by an efficient patent examination system aligned with international standards. Understanding the landscape involves examining prior art, related patents, and regional filing strategies.
