Nanosys, Inc. today announced it has agreed to settlement terms of a patent infringement lawsuit against Nanoco Technologies Ltd. The lawsuit claimed that the United Kingdom firm's quantum dot technology infringes upon five seminal quantum dot patents held by Nanosys. In the settlement, Nanoco agreed to terminate its current U.S. business for its core-shell quantum dots. Those quantum dots were sold in the U.S. by its U.S. distributor, Sigma-Aldrich under the name Lumidots. In the settlement, Nanoco did not admit that the asserted patents are either infringed or valid. Additional terms of the settlement were not disclosed.

Nanosys is currently using its quantum dot technology to make process-ready components for solid state lighting, solar power and electronic display systems. Nanosys has the exclusive rights to more than 700 patents and applications covering fundamental aspects of its materials technology, including its quantum dot technology.
