Because device vendors license the patents, at least if Microsoft bugs them to. One reason Microsoft went after TomTom so hard is that they didn't want to give other device vendors the impression that they could let their licensing slide.

The way I see it, Microsoft went after TomTom knowing that it was highly unlikely they would take it to court. TomTom is a reasonably big name though ,so they get a bit of pseudo-creditability in other peoples eyes , that don't understand the fact that TomTom was too broke to take it to court.
