About this actor
Group of former ASML employees later named in the long-running ASML v. XTAL civil trade-secret litigation (separate from the criminal track), arising from a wave of departures from ASML's Brion photomask software unit to XTAL Inc., a Dongfang Jingyuan affiliate. A US jury ultimately awarded ASML $845M in 2018.
