Wilmer Cutler Pickering Hale & Dorr has filed a trade secrets complaint on behalf of Roche Molecular Systems Inc. against Stanford University, three Stanford oncologists and the biotechnology company they co-founded, Foresight Diagnostics of Colorado.

The complaint, filed Monday in the U.S. District Court for the Northern District of California, San Jose Division, alleges the scientists wrongly used Roche’s proprietary cancer-detection technology and “secretly co-founded Foresight at the same time they were serving as consultants and contractors for Roche.”
