IANAL as will be pretty evident from this confused series of questions, but from the article: 'They claim to have patented the method of using GPS location on vehicles to determine when they will arrive at a certain place,'
So, did they patent it or not? And if they did, then who the hell approved it as a valid innovation???!
If they didn't patent it then it's just a case of straight up fraud isn't it? Conversely, if they do actually hold this patent, then isn't just as clear cut that this poor guy is infringing it - no matter how ridiculous that seems? The article seems to suggest that they are now reviewing whether the patent is valid or not - but once a patent is granted doesn't that automatically mean it's valid too?
