Three former Genentech workers and another individual have been hit with the trade secret equivalent of a double whammy.

In a federal indictment unsealed Monday, Xanthe Lam, a principal scientist who was with Genentech from 1985 until last year, her husband Allen Lam, and James Quach, who both also logged time at Genentech, were charged with stealing trade secrets to help the company’s Taiwan-based rival JHL Biosciences make biosimilar versions of Genentech drugs, alongside John Chan.
