Coherent and Lumonics cross-license patents
Coherent Inc. (Santa Clara, CA) and Lumonics Inc. (Ontario, Canada) cross-licensed several of their excimer-laser patents. Under the terms of the agreement, Coherent licensed its neon-buffer gas patent (#4,393,505) and output-control patent (#4,611,270) to Lumonics on a nonexclusive basis. In turn, Lumonics licensed its hydrogen-buffer gas patent (#4,340,368) to Coherent on an exclusive basis. The patents apply to all excimer lasers, but especially to those operating at 248 and 308 nm for various medical and industrial-processing uses.
