I don't think this is possible worldwide. In Europe, software
patents do not exist and cannot be granted. There was an attempt to
change this lately, but (luckily) it failed for the time being. The
European Commision was convinced by open source advocates that
software patents are bad. At least it made them think twice and
postpone the process.
The only thing you can protect is the implementation (the program,
in this case to read/write the protocol) under copyright.
Thus 'anyone' could learn the protocol from looking at the driver
sourcecode and then implement a drop-in replacement for the card
hardware.
As others have said, given the rapid developments in the 3D graphics
world, that hardly seems practible though.
