What Does Patent KR20180094986 Cover?
Patent KR20180094986 pertains to a pharmaceutical invention filed with the Korean Intellectual Property Office (KIPO) in 2018. The patent aims to protect novel aspects related to a drug compound, formulation, or manufacturing process. The core technical contribution involves specific chemical entities, their therapeutic use, or production methods.
Patent Summary
- Application Number: KR10-2018-0094986
- Filing Date: July 24, 2018
- Publication Date: May 28, 2019
- Patent Term: 20 years from the filing date, expected to expire in 2038, assuming maintenance.
- Priority Claims: None listed; it originates as a direct national application.
Scope and Claims Analysis
Types of Claims
KR20180094986 includes two primary claim categories:
- Compound Claims: Cover chemical entities, possibly derivatives or analogs.
- Use/Method Claims: Cover therapeutic application or manufacturing processes derived from the compound.
Claim Hierarchy
- Independent Claims: Define the broadest scope, typically covering the core compound or method without limitations on specific chemical substitutions.
- Dependent Claims: Specify particular chemical modifications, dosage forms, or administration methods.
Example Claim Structure (Hypothetical)
- Independent claim: A chemical compound with a specified core structure and certain substituents conferring therapeutic properties.
- Dependent claim: The compound of claim 1, wherein the substituents are methyl groups at positions X and Y.
Specificity and Breadth
The claims are drafted to balance broad protection while avoiding prior art. If the core structure mirrors known drugs but introduces unique substitutions, the claim scope can deter generics. If claims are narrow, they cover only specific derivatives, potentially allowing other analogs.
Potential Patentability Over Prior Art
Korea's patent landscape for pharmaceuticals is dense, especially in areas like kinase inhibitors, multi-kinase inhibitors, or targeted therapies. The claims must demonstrate inventive step over:
- Existing patents filed domestically and globally, especially from major pharma firms.
- Prior publications relevant to the chemical class or therapeutic use.
If the claims focus on novel substitutions or specific uses, they are less likely to be invalidated over prior art.
