An open letter from Alan Cox
Patents don't work like that. If you invented it, you have to get the patent.
An alternative is to build up a GPL patent pool: patent every interesting feature of your GPLed application, then license the patent for free use in GPLed applications, and then cross-license the patents with others in exchange for them adding their patents to the list of GPL-licensed patents.
Some organization would need to be empowered to handle the cross-licensing; if enough patents could be obtained, the threat from outfits like Microsoft could be greatly reduced, as anyone producing software would need access to these patents to stay in business. They would need to deal. However, there would be no protection against lawyer-only shops that own patents; they wouldn't need to cross-license.
I don't particularly like this strategy -- it's a huge problem for non-copylefted software. Perhaps anyone could be allowed to use a patent in the patent pool if full source is provided to all recipients and the recipients have all the rights the DFSG talks about. That, however, would have the effect of imposing copyleft on the non-copyleft world: you'd lose your patent license if you try to take the app proprietary.
I'm afraid that the reason this scheme would be unlikely to work is that a sizable patent pool would have to be accumulated in a way that one organization could aggressively manage it. If it's decided to license patent X to Microsoft in exchange for patent Y, then some other free software project that needs patent Z instead will object.
