The IPR issue on building trees popped up during the Autoconf 
meeting. I can say BRDP is inspired by TD, but have a very 
different target. I checked again the patents in the claim
on RPL.
My opinion is that the patents are NOT applicable to BRDP. This 
because BRDP is NOT about building topologies and NOT about routing.
The patents are.

There is a BRDP related draft on routing: draft-boot-brdp-based-routing.
This is a very different approach than what is described in the patents.
My proposal leaves providing paths to the routing protocol.

Pointers to the RPL IPR topic: 
http://www.ietf.org/mail-archive/web/roll/current/msg03095.html
https://datatracker.ietf.org/ipr/1270/

To repeat Pascal: 1) I'm not a lawyer, and 2) even less your own 
lawyer. If I'm wrong, I expect Cisco takes action.

Even if Cisco claims, I think there is no problem, with the outcome
in ROLL in mind. Also, Cisco was aware of my work from the very
beginning. The IPR issue never raised.
