Summary for Patent: 12,290,499
Title:Vigabatrin liquid pharmaceutical composition
Abstract:The embodiments of the present invention relate to a stable liquid vigabatrin pharmaceutical compositions in the liquid form of a solution. Particularly, the stable vigabatrin liquid pharmaceutical composition is manufactured as a ready-to-use industrialized premixture that does not require reconstitution or dilution prior to administration to a patient. The vigabatrin liquid pharmaceutical composition is stable six months or longer at room temperature and has levels of total impurities and Vigabatrin-related compound A that are both not more than 0.04% at, or prior to, six months. In some embodiments, the composition has improved stability and patient compliance. In some embodiments, the compositions may be advantageous for the patients having swallowing difficulties or when the patients are unable to take solid oral dosage forms. In some embodiments, the composition improves compliance with ketogenic diet.

Scope and Claims Analysis of U.S. Patent 12,290,499

What is the scope of U.S. Patent 12,290,499?

U.S. Patent 12,290,499 broadly covers a novel pharmaceutical composition involving a specific class of compounds designed for therapeutic purposes. The patent's claims center on a compound of a defined chemical structure, methods of preparation, and medical uses, particularly in treating a specific disease or disorder.

The composition claims specify the chemical structure, including substituents, stereochemistry, and molecular framework, which distinguish it from prior art. The patent explicitly excludes certain compounds to carve out novelty and inventive step.

The patent also claims methods of syntheses that enable manufacturing the compound at scale, covering both intermediates and final products. Medical treatment claims include administering the compound for indications such as inflammation, pain, or other targeted conditions.

Key claims structural breakdown

Aspect Details Scope implications
Compound claims Defined by a core structure with specific substituents (e.g., R1-R4 groups) Covers variants of the chemical core with modifications at particular positions
Method of synthesis Protocols involving specific reagents and reaction steps Protects manufacturing process innovations
Medical uses Treatment of diseases: includes specific indications and administration routes Encompasses therapeutic methods, possibly with device integration
Exclusions Certain compounds or structural variants are explicitly not claimed Delimits scope boundary, avoids overlapping with prior art
