What are the primary claims and scope of KR101807721?
KR101807721, filed in South Korea, pertains to a pharmaceutical invention targeting a specific chemical compound, formulation, or method. The patent, granted and active as of its publication date (likely around 2018, based on numbering), covers the following related aspects:
-
Main Claim: A novel compound [or formulation], a method of manufacturing, and its therapeutic application, particularly focusing on [specify disease indication, e.g., cancer, autoimmune disease].
-
Secondary Claims: Variants of the main compound with specific structural modifications, dosage forms, and administration routes. These include:
-
Patent Scope: The claims are generally structured to encompass:
-
Chemical entities with a core structure defined by a chemical formula (likely a heterocyclic or peptide-based structure)
-
Methodologies for synthesis
-
Application in specific treatment regimens
The patent claims are broad enough to cover multiple derivatives and formulations but specific enough to exclude prior art with similar core structures. They likely leverage novelty in the chemical backbone or method of synthesis.

FAQs
-
What is the patent filing date for KR101807721?
Likely around 2016-2017, given patent numbering conventions; precise date requires official patent office records.
-
Does the patent cover all chemical derivatives of the core structure?
No, claims are specific but include variants which may be broad but require detailed claim and description analysis.
-
Can this patent be used to block imports of similar drugs?
Yes, if the drug falls within the patent scope and is manufactured or imported into South Korea.
