The GPL really needs an improved clause about patent licensing too. (The GPL
could easily be a patent pool. Right now the language says that patents must
be licensed for use by everybody, when all it really NEEDS to say is that the
patent needs to be licensed for use in GPL programs. in regards to patents,
the GPL acts like the BSD license, rather than copyleft, and that would be
really easy to fix.)
The GPL is sort of becoming a patent pool anyway, with Red Hat licensing its
patents for use in GPL programs only, and IBM making noises about that,
etc... But it's not explicit, and it's not really one pool that you join
automatically by participating, and that violation of the GPL could block you
from access to all of...
Richard Stallman, unfortunately, is a zealot. He wants to log roll a whole
bunch of things like addressing the application service provider issue into a
GPL 3.0, which means there probably never will be a GPL 3.0. And he won't
issue a GPL 2.1 with minor issues like these because that would erode the
chocolate coating on the other unpopular issues he wants to lump together
into a big "take it or leave it" upgrade at some nebulous point in the future
that pushes unpopular elements of his agenda as part of the package...
Sad, really. Oh well. I suppose somebody could come out with a "GPL patent
pool license", which might not violate the GPL. The preamble says "we have
made it clear that any patent must be licensed for everyone's free use or not
licensed at all", but doesn't say who everyone is (since the license only
applies to people who accept the license, then it could logically be
"everyone who agrees to the GPL".) Clauses 7 and 8 mention patents, but
don't specify any license terms for them. Therefore, you NEED a patent
license, but the GPL doesn't give the text of it.
So if the GPL is just a copyright license, and it requires patents be licensed
but doesn't specify the terms, therefore it's legal (and in fact expected) to
combine the GPL with a (compatable) patent license. But there IS no standard
GPL patent license. It would be nice if there was one, that could be
regularly combined with the GPL in a standard way (GPL+), saying that the
patents are licensed for use in GPL-licensed software only, as part of a GPL
It's one way to bypass Stallman's log-rolling, anyway...
