MRT transponders aren't 'counterfeit' or 'copies' - they are simply devices that transmit a radio signal with specific properties. Mylaps can't patent that though they are the only ones can generate new codes (ie a new set of specific properties) and be sure the system will recognise them. So the code generating system is patented, but the transmission isn't.
Since MRT are quite clear about where their codes come from (old AMB units), and the circuits they use are nothing like the one in an AMB/Mylaps unit no laws have been broken, no theft occurred. Suggesting otherwise is in fact rather libelous. Do you really think AMB/Mylaps would have let them keep going this long if they had?

Though I rather like the idea of a Chinese firm making a true rip-off. There is a lot of money to be made, and it would serve Mylaps right for price gouging. Please notice that Chinese esc market hasn't killed US or European esc companies but it has dramatically reduced their prices.
