I wonder if those sales could be force to an open market. A bit like anti trust laws. I'm sure they would pay a lot more for their trademarks if other companies could otherwise snitch it for like a year. Or why not having to accept or at the least pay taxes on the best offer you get, when you want to sell to some IP and later lease it from some other company? Yes, that seems unrealistic. It might at least be possible to use this in e.g. the court of law to test for abuse.
