If there is an explicit patent grant in GPL 2.0, it's certainly
news to me.  Your patent grant in CeCILL, however, is so broad that
as written it raises the possibility of "patent laundering," i.e.,
Licensor's patents which are completely unrelated to the covered code
may be inadvertently licensed by releasing code under CeCILL.
Please see the patent grants in licenses such as EPL, CDDL, and
Apache 2.0 for more broadly acceptable terms which do not allow
"patent laundering."

Internationalization is good. Vanity licenses are bad.  If you are
arguing that GPL is not enforceable in the EU and a new license
is required, there are multi-million lines of European-written GPL
code which would seem to prove that the free/open source software
community of the EU does not agree with you.
