Thales plots retaliation for Honeywell's lawsuit
Thales Avionics has threatened legal reprisals against Honeywell unless the U.S.

Thales Avionics has threatened legal reprisals against Honeywell unless the U.S. avionics and engines giant drops a patent-infringement lawsuit against Phoenix-based Aviation Communication & Surveillance Systems (ACSS), a maker of terrain awareness and warning systems (TAWS), TCAS and mode-S transponders, jointly owned by Thales and L-3 Communications.

In a letter to Honeywell last month, Thales issued a sharply worded warning that if Honeywell continues its alleged “unlawful practice” of using the former’s patents in the latter’s Enhanced Ground Proximity Warning System (EGPWS) the French company plans to file a series of patent-infringement lawsuits against Honeywell in U.S. and European courts.
