Basically what Nintendo did on one of their schemes to prevent unauthorized software (Famicom Disk System, which was a floppy disk drive for the Japanese version of the NES). This was the physical Nintendo logo embossed on to floppy disk and with a flat disk instead, the disk can't be physically loaded (sort of, you can add extra cut outs). Other game systems required a logo or similar other brand/trademark/IP to be present in the game code in order to boot, so if you wanted to make your own game without Nintendo's blessing, you had to invlude their IP in your physical disk or in the game code just to get it to boot. This BMW patent seems to be in the spirit of those hard and software protections that prevent people from doing what they want with the hardware (car) they bought.
