July 23, 2009: Nanosys Inc. and UK-based Nanoco Technologies are settling a lawsuit brought by the US firm alleging infringement of five patents involving quantum dot technology. The resolution will result in Nanoco terminating its US business for its core-shell quantum dots, sold through Sigma-Aldrich under the name “Lumidots,” though the company admits neither the patents’ validity nor any infringement thereof. Additional settlement terms were not disclosed.
Nanosys says its quantum dot technology is currently being used in process-ready components for solid state lighting, solar power and electronic display systems, and that the firm has exclusive rights to >700 patents and applications covering “fundamental aspects of” its materials technology, including the quantum dots.
