I don't know what you mean.  GPLv3 final says:

"you may not initiate litigation (including a cross-claim or
counterclaim in a lawsuit) alleging that any patent claim is infringed
by making, using, selling, offering for sale, or importing the Program
or any portion of it."

Violations of this will result in termination:

"(including any patent licenses granted under the third paragraph of
section 11)."

Do you think the above clauses are insufficient for compatibility with
the Apache 2.0 patent clauses?  I think FSF believes in good faith that
Apache 2.0 is compatible.

I think this may be too subjective as a criterion.  Anyway, my point is
that GPL should not be singled out as anti-compatibility, which it isn't.
