This is all fine.

The copyright licence is a standard 3-clause BSD, and totally
DFSG-free.


The patent licence is a very usual kind of permissive patent licence.
Some people on debian-legal object to the software patent retaliation
termination clause, but I think it is fine and many similar licences
can be found in main.

And anyway, in the absence of known problems, we do not normally
investigate patents in software we are considering accepting.  Doing
such investigations is ill-advised:
