However, in practice, incompatibility issues between patent licenses and any version of the GPL which has been published so far are not typically the result of specifics of how the GPL implements the concept of copyleft, but rather the incompatibility issues usually result from those patent licenses being incompatible already with the basic concept of open source / free software. Combining such a patent license with a copyright license of any kind for some program cannot possibly result in a program which is open source / free software. Therefore copyleft licenses must by definition be incompatible with such patent licenses. The question is this: Is copyleft open source / free software so unimportant with regard to any area of internet standards that it would be justifiable to adopt any specification with fundamentally incompatible patent situation as a standards-track RFC? I believe that the answer to this question very clearly is no! For justification of this position I point to the facts that Microsoft is clearly acting like it perceives copyleft open source / free software to be the main threat for their near-monopoly market position, and that in the domain of networking equipment where there is not a problem with a Microsoft near-monopoly, a very similar problem nevertheless exists from the perspective of developing countries.
