    After reading the draft, I must respectfully disagree.  Although it 
    doesn't state explicit legal conclusions such as "X is covered by patent 
    Y", it makes statements of opinion like "X uses techniques from Y (which 
    is patented)" or "X is fundamentally different from Y", which, if the 
    reader believes these assertions, leads him/her to a corresponding legal 
    opinion.  I would suggest that opinions w.r.t. IP be struck from the I-D.

    But by that standard, so has SRP.  Has Phoenix (or Integrity Sciences) 
    ever requested any IPR statement from Lucent regarding the EKE patents, 
    similar to what the IPS WG has gone through the last few months?

    Are "unsupported opinions" proper/improper in an Internet-Draft, though?
