If you look at the page they used to file the disclosure:

https://datatracker.ietf.org/ipr/new-specific/

You'll notice that they chose the most relaxed option available, and 
all the options only discuss implementers not distributors.

Now, if you look at the background commentary of the subject:

http://tools.ietf.org/html/rfc3905

.. the comment about that particular option is:

    a) No License Required for Implementers: The Patent Holder does not
       require parties to acquire any license to its Necessary Patent
       Claims in order to make, have made, use, import, offer to sell,
       sell, or distribute technology that implements such an IETF
       specification.

Seems clear to me, though someone could argue whether RFC 3905 is 
normative in this context, i.e., whether the person who submitted the 
disclosure understood the comment quoted above and that that's the way 
"no license required for implementers" must be interpreted.
