University of Arkansas Joins QD Patent-Infringement Case Against Nanosys

Quantum dots technology developer NNCrystal US added the University of Arkansas board of trustees as a second plaintiff in its patent-infringement lawsuit against Nanosys (see 1907150019), said an amended complaint (in Pacer) Wednesday in U.S. District Court in Wilmington, Delaware. The lawsuit accuses Nanosys of producing QD materials in California using processes that infringe U.S. patent 7,105,051. The school owns the 13-year-old patent, but gave NNCrystal an exclusive license to the invention, including the right to sue for infringement, said the complaint. Xiaogang Peng, one of the patent's three Fayetteville, Arkansas, inventors, who was a chemistry professor at the university before he left teaching and founded NNCrystal in 2001 to commercialize his inventions, it said. Nanosys declined comment Monday. It previously denied NNCrystal’s infringement allegations.
