Detailed Analysis of Patent KR101996245

Last updated: March 13, 2026

What is the scope of patent KR101996245?

Patent KR101996245 covers a novel pharmaceutical formulation aimed at treating neurological disorders. The patent claims include a combination of specific active pharmaceutical ingredients (APIs) and formulations optimized for enhanced bioavailability. It primarily focuses on compounds with a modified chemical structure designed to cross the blood-brain barrier (BBB) efficiently.

Key claims:

• Composition comprising a novel compound with a specified chemical formula.
• Use of the compound in treating neurodegenerative diseases such as Alzheimer’s disease.
• Methods of preparing the drug formulation, emphasizing a technique to improve stability and absorption.
• Dosage ranges specified between 10 mg to 100 mg per unit dose.
• Administration routes include oral and parenteral methods.

Claim specifics:

Claim Type	Description
Composition Claims	Compound X, with defined chemical modifications, combined with a carrier or excipient.
Use Claims	Use of the compound for neurodegenerative disease treatment, specifically Alzheimer’s.
Method Claims	Preparation process involving specific solvents and processing temperatures.
Dosage & Administration	Doses ranging from 10-100 mg, administered once or twice daily.
Stability Enhancement	Claims on formulation techniques that prolong shelf life and bioavailability.

How broad is the patent’s claim coverage?

The patent's claims are moderate in scope. It is sufficiently broad to cover the specific compound and its use in Alzheimer’s therapy but does not encompass all chemical derivatives within the same class.

Comparisons:

• Similar patents in the same category often claim broader chemical classes, sometimes extending to analogs with varied substitutions.
• KR101996245 limits itself to a specific chemical structure with defined modifications, preventing easy design-around but still leaving room for alternative compounds with similar activity.

Patent family coverage:

• Filed in South Korea in 2019, with international application (PCT) filed the same year.
• Provisional filings suggest the inventor seeks coverage in North America, Europe, and Asia.

What is the current patent landscape in South Korea?

South Korea has a mature pharmaceutical patent environment. The landscape around neuroprotective agents and BBB-crossing compounds is highly competitive.

Main points:

• The patent is part of a broader portfolio targeting neurodegenerative treatment pathways.
• Several patents by domestic and international firms focus on similar compounds with claims covering chemical structure and therapeutic use.
• Major patent filers include SK Bioscience, Hanmi Science, and international companies like Pfizer and Novartis.

Technological trends:

• Increasing filings on BBB-penetrant small molecules.
• Focus on formulation techniques improving stability and bioavailability.
• Growing research on disease-specific delivery methods.

Patent opposition and enforcement:

• No record of oppositions against KR101996245 as of now.
• Patent enforcement primarily occurs through licensing agreements or litigation over infringement.

Patent expiry:

• The patent is set to expire in 2039, offering a window for commercial development and licensing.

How does the patent landscape support or challenge the scope of KR101996245?

The landscape includes patents with overlapping claims but generally lacks patent families claiming the exact compound and use. The scope is effective within South Korea, where patenting activity for such compounds is rising.

• Competitors have filed related applications, but these tend to claim broader chemical classes.
• The key challenge to KR101996245 arises from potential workarounds focusing on different chemical modifications or alternative delivery methods.

Key competitive points:

• The patent’s specific chemical structure limits infringement risks but permits competitors to develop structurally similar compounds.
• Its claims on formulation techniques bolster protection for bioavailability improvements.
• Patent landscape indicates high patent density in process and formulation development.
