Not likely to be a problem with patents

More spesifically, I see this system as having most (not all, but most) of its potential use in developing countries. Of course the developed world has lobbied for ever stronger patent and copyright restrictions around there too (often tying slightly more freedom of trade for physical goods to significantly less freedom in general (trade included) for information in a cringeworthy double standard).

But I wonder if GSM patent holders have bothered to apply for relevant patents in every technological backwater, considering that they are indeed generally country-specific. I don't know, but I doubt it. Anyone have any solid data on this?
