Hi,

Sorry for following up on my own message, but I will be brief, and stop 
after it.

I did some search.

The writer of the method 'MAC Address Generation' in the draft confirmed 
to me by email that he had no IPR claims on this method, even though he 
separates his reponsibility from others' (he cant realistically know 
what others do, which is obvious).

The ETSI ipr.etsi.org portal search on TS 102941 (the document that 
specifies the means to generate a privacy MAC address) issues no results.

The IPR search on qpat issues several IPRs when the title keyword is 
"MAC Address Generation".  Some of these methods, e.g. "CN105430118  B" 
or "JP2012222709  A", have an abstract that approaches a lot to what 
this method in IPv6-over-OCB does, even though there are differences in 
the number of bits used.

For IEEE I do not know how to search IPR status and I surelyt dont have 
necessary credentials.

I am not trained as a technical patent specialist, so that's how I see it.

For reminder, the MAC Address generation in IPv6-over-OCB draft is:

>

This is the best I could do for this IPR topic, I stop here.
