It goes further than that... It's not the method that counts as much as the claims presented. You can fill a patent that would state in the Claims part something as vague as 'Cleans your butt with lateral hand movement' describing the method how you clean your butt with their toilet paper, and then you can get sued if you sell a bidet that utilizes the same 'technique' and get sued for infringing on their toilet paper patent. Of course, this is a bit pushing it, but that's how today's patent system works - if something you do appears in the claims of another patent, you can get sued easily, and even if you can prove that yours is a completely different method you would still need millions of dollars just to fight it at court which many small companies / individuals just cannot afford. It's legalized bullying!

Here is a nice testimonial from a guy that managed to fight them off: http://youtu.be/E_lb3D7Ay-M , sadly - on each such testimonial, there are 100s of testimonials of business collapsing due to inability to fight them. If you have the time, seek for the documentary 'Patent Absurdity', they show quite colorful ways on how patent trolls and troll-like companies operate. And why you have to become a patent troll yourself if you want to survive. Sad world...

Anyway, back to the topic, let's talk Nokia stock... Probably closing the week at a shy bit over $3 on NYSE, and 2.4€ dead on ETR... What stock?! They are now almost twice as much valuable sold in parts than their market value, a hostile takeover is quite possible, although I think the potential buyers will wait for Elop to sell out everything non IP related with his obvious gambling habits to fuel his delusion... The moment he lays his eyes on the IP and start selling it en masse somebody will take them over. Probably Microsoft, if they are willing to risk investigation that would surely ensue in that scenario.
