I don't think that clause is a problem. US export laws will (or won't)
apply regardless of what the licence says, so this is really just a
matter of information. It doesn't affect the DFSG-freeness of the

This is rather an odd one. It's not clear in the context of the
relevant paragraph whether this is just making a statement of fact
about the Source Code as you may be using it, or whether it is seeking
to claim ownership of any modifications that licensees make. If the
latter, then I suspect that in a lot of jurisdictions it will not
actually achieve the desired effect - for example, UK copyright law
requires an assignment of copyright to be in writing and signed by the
The question is then whether this interferes with software freedom. If
you create a derivative work from the software, then (making the *big*
assumption that the clause is legally effective) the copyright in that
work, including your modifications, will vest in OpenVision. However,
you still have the benefit of the licence terms as regards those
modifications, so it doesn't interfere with your freedom on a
What it does potentially mean is that OpenVision can *additionally*
license your modifications under non-free licence terms, which many
developers may consider undesirable. But OpenVision would be taking a
risk if they actually did this, given that it is highly doubtful that
they can claim legal ownership of the copyright in licensees'
modifications on the basis of this licence provision.
It probably wouldn't hurt to raise this with OpenVision, if possible.
Do they consider this clause to give them ownership of copyright in
any modifications made to the software, or is it simply saying that
your rights under the licence do not affect the ultimate ownership of
I don't think the DFSG-freeness is affected in either event, but if
OpenVision are trying to claim ownership of modifications then this is
unusual, undesirable and probably ineffective.
