Questionable. The consensus for a similar clause in OSL 2.0 was that
that was non-free; this is a little different because it only
applies to Modifications, whereas the OSL 2.0 clause included the
Covered Code as well.

This last part is questionable. If the outside of a Debian retail box
carries copyright notices for the box design, would the Object Code
Notice have to be there too?

If you download a copy of the Covered Code to disk or copy it from
disk to RAM, without making any modifications or distributing it, you
are barred from bringing a patent suit against Real.com based on what
you read in it? While I appreciate the intent, it seems bogus.

This upgrade clause is a little strange, and may discourage other
developers from using RPSL: Who would have to publish the new version
of the license? If Real.com published a new version of the license,
could end users "upgrade" third party RPSL-licensed code to that
without permission from the third party author?

This is enormously broad; more restricted clauses in OSL 2.0 (see
above) and the IBM Public License were considered non-free because the
patent in question need not be related to the Covered Code. Any
patent suit at all against Real.com would terminate the license.

US copyright law does not limit use of a legitimate copy; without some
sort of affirmative assent from the user, that part of this clause may
not be binding. I think that's not a DFSG issue, but one for the
licensor to worry about.

Choice of venue clause plus express submission of jurisdiction: the
DFSG freeness of this is being debated separately. I do not believe
there is yet consensus on that subject.
