Patent Overview and Technical Background
KR20180085823 was filed on March 23, 2018, with publication details available via the Korean Intellectual Property Office (KIPO). Although the specific therapeutic area is not explicitly provided here, structural indications suggest it pertains to a novel active ingredient or a specific formulation enhancement that improves drug efficacy, stability, or delivery.
Most likely, the patent’s objective is to address unmet needs in treating a particular condition—potentially in oncology, neurology, or infectious diseases—by providing a new chemical entity, combination, or delivery system.
Scope of the Patent
The scope of a patent defines the breadth and boundaries of the rights granted, primarily dictated by the claims. Broad claims encompass a wide range of embodiments, providing extensive patent protection, while narrow claims offer limited coverage but may be easier to defend.
1. Types of Claims
KR20180085823 features a combination of independent and dependent claims:
-
Independent Claims:
These establish the core invention. For instance, they likely claim a specific chemical compound, a unique formulation, or a method of manufacturing or administration.
Example: "A pharmaceutical composition comprising [core active ingredient] and a stabilizing agent, wherein the composition exhibits enhanced bioavailability."
-
Dependent Claims:
These specify particular embodiments or adding features such as specific dosages, excipients, or physical forms, narrowing the scope.
2. Claim Language and Structure
The claims probably employ technical and precise language, incorporating chemical nomenclature, process steps, or specific parameters (pH, stability factors). Clarity and proper scope are essential to withstand validity challenges.
3. Core Elements of the Claims
-
Chemical Compound or Composition:
- Claiming a novel chemical entity with unique substituents or stereochemistry.
- Claiming a combination of compounds with synergistic effects.
-
Formulation and Delivery:
- Claims covering formulations such as sustained-release, nano-carriers, or targeted delivery systems.
-
Use or Method of Treatment:
- Claims may cover methods of treating a specific disease using the compound or composition.
