IIRC the seller of any system with CAN in it has to pay Bosch a small license fee (3 pfennigs per node?).  In the case of microcontrollers this is done by the manufacturer of the uP, which is passed on to the OEM, but I'm not sure what would happen in the case of an FPGA implementation... and IANAL!
