Intellectual Property Statement for the sampling techniques draft

[Benoit Claise <bclaise@cisco.com>]

Hi,

During his session, Nick Duffield mentioned that he wrote an IPR section 
in the sampling techniques draft, and that potentially we might need one 
for NetFlow.
I started to investigate and this leads me to this question.
The IPR statement is pretty vague, specifically if I follow the link

 10. 
     Intellectual Property Statement 
  
    AT&T Corporation may own intellectual property applicable to 
    this 
    contribution. The IETF has been notified of AT&T's licensing 
    intent for the specification contained in this document. See 
    http://www.ietf.org/ietf/IPR/ATT-GENERAL.txt for AT&T's IPR 
    statement. 

Should we specify exactly which method(s) AT&T has got a patent for? And what is the patent number?
For example, the NetFlow IPR is pretty unambiguous.

Thanks for shedding some light.

Regards, Benoit.
