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.
