The only thing you can do, technologically, is to plant an easter egg or
non-functional bit of code in there (preferrably one which is made so
that it won't work without it, of course, and appears to perform some
needed function).

At least then you can say to the governing body of whatever nation/state
you need to prove this in "I know hese chips have my code, I can twiddle
this pin this way, and get this useless response, something they would
not have added themselves."

Legally all you can do is get a good lawyer that knows how to deal with
overseas legal issues - very pricey, but you need to decide how much it
is all worth to you.
