Patent KR20090040340: Scope, Claims, and Landscape Analysis

Last updated: February 22, 2026

What is the scope of patent KR20090040340?

Patent KR20090040340 covers a pharmaceutical compound, likely a novel chemical entity or a specific formulation used for therapeutic purposes. The patent aims to protect the compound's unique chemical structure, method of synthesis, or therapeutic use. The scope extends to:

  • Chemical compounds with defined structural formulas.
  • Processes for synthesizing the compounds.
  • Medicinal formulations containing the compound.
  • Therapeutic applications, including specific indications or treatment methods.

The patent claims focus on establishing exclusivity over chemical entities with certain structural features and their medical uses, preventing the development of generic alternatives that infringe on these aspects.

What are the key claims?

The patent’s core claims typically include:

  • Compound Claims: Protection of a chemical compound with a specific structure, possibly represented as a core scaffold with defined substituents. The claims specify the chemical structure, including optional groups, to cover derivatives and analogs.

  • Synthesis Method: Claims related to the specific steps or processes used to produce the compound, providing a patentable process barrier.

  • Pharmaceutical Composition: Claims regarding formulations that include the compound, such as tablets, capsules, or injectable forms.

  • Therapeutic Use Claims: Use claims describing the compound's application in treating particular diseases or medical conditions, such as cancer, inflammation, or infectious diseases.

The claims are usually structured to cover both broad classes of compounds and narrower, specific embodiments to maximize patent protection.
