Copyright vs. patents, source code vs. compiled binaries, etc. 2012-07-12 21:56:43 Quote from: saratoga on 2012-07-12 21:01:32Off hand I can't think of any that force you to also provide patent licenses to go with the software license, since in practice that would be almost impossible to know which patents were covered and which were not.GPL includes a patent license for all patents you own and apply to the software. You'd obviously know which of your own patents applies.At least in GPL3 there are also provisions that block you from relying on a patent license to be able to convey a work covered by one. (But I find the clauses a bit strange because they are null as long as you also convey source code - which the GPL requires you anyway?)But yes, no open source license requires you to acquire licenses for any patent the software might infringe before you can distribute it - because that's obviously impossible.
