excuse me, navigation patents from this century should not have been awarded.
Philips NatLab was doing that stuff in the nineties (possibly earlier). (Yes that predates GPS, they used other means to figure out where they are.) The CARIN systems were sold to the mass-market by Philips a decade ago. Philips's navigation devision became independent as VDO Dayton, later sold to Siemens who last year or the year before that sold that devision to TomTom.
So TomTom should be sitting on the patents that:
a) show prior art
b) can go after Microsot for themselves.
So we are left with the attack on Linux and FAT.
