I feel very strongly that software patents are out of scope for the
DFSG.  There are some DFSG-compliant licenses, such as the GPL, which
require contributors to license their patents freely, but this is not
the same thing.  Is a software license that offers a limited license on
any applicable patents really less free than one which makes no mention
of patents at all?

Now, if we have strong reason to believe that the patent holder is
likely to enforce those patents against someone creating a derivative
work from this software, that may be grounds to keep the software out of
Debian for the protection of our users and redistributors; but that's
not a function of the DFSG, IMHO.
