Advanced Micro Devices Inc is suing Cascade Microdevices Inc and a former Advanced Micro executive alleging misappropriation of trade secrets, breach of contract, interference with contract, and unfair competition: AMD alleges that Cascade recently hired former AMD executive Ronald Treadway as its vice-president of Product Development and that Treadway then proceeded to use AMD confidential and proprietary information to recruit other AMD employees to work for Cascade – five of the 16 professional design employees in AMD’s Transparent Asynchronous Transceiver Interface – TAXI – chip programme have accepted employment with Cascade since Treadway quit.
