I don't understand the patent office. A system I repair has a SAW touchscreen that can sense how hard you touch the screen and that can be used to changed what happens. This system is from before 1993 and has a DOS 6 byte serial interface. The newer stuff has 8 byte. There is a utility that allows one to "see" the bytes and you can see the numbers change with pressure and it is not just X and Y.

If I understand correctly if something is out in world you only have a year to get a patent
