Neil,

With all due respect, the PS has a fatal logic flaw.

The statement would certainly be true if the stolen IP were a complete set of masks (e.g., the well-known case of the Russian uVAX clone). If would also be true if the involved IP was that which is at the heart of the problem.

However, that does not exclude the possibility that some (emphasis: SOME) IP was misused somewhere else on the chip.

An example of that well-worn error: Some men are doctors; some men are tall, therefore some doctors are tall.
