Very specifically on these, I think it would be useful to classify the IPR and related assets that the existing XSF has. My non-exhaustive guesswork gives me:

* Trademark licences (I think the XSF has a trademark licence for Jabber, though I can't find it)

This document can be found here <https://xmpp.org/docs/Trademark_License_Agreement.pdf>, as linked from <https://xmpp.org/about/xsf/jabber-trademark/background/>. Note that this document specifically disallows sublicensing, but read on below.

* Trademark sublicensor: https://xmpp.org/about/xsf/jabber-trademark/

Even though the JabberⓇ Trademark License Agreement clearly asserts that there is an agreement between the XSF and Cisco to offer a sublicensing program, we do not currently have any public document that explicitly shows this. I've been working with Peter to assess the relevant documents and whether we can make them publicly available. If so, we will make sure to add them to this section of the XSF website.

I will provide an update when I have more to share.

Cheers,
