Patents have almost nothing to do with licenses, we have many things in
the Linux kernel that are under a GPLv2 license that have patents issued
for (and are actively enforced.)  The GPL can, and does, work with the
patent system, so if that's a reason that any company tries to give for
not releasing kernel code, it's very misinformed.

Anyway, off-topic but I figured I would try to clear that up.

good luck!
