Nortel Inc. has excluded claims from U.S. patent no. 6,701,366 from the W3C RF licensing commitment.

The Voice PAG on CCXML recommends:

  1. that the Voice Browser Working Group proceed with the further advancement of CCXML on the way to Recommendation status
  2. that the Voice Browser Working Group remain observant about eventual assertion of US Patent no. 6,701,366 against implementers of CCXML and will report those back to the Working Group and to the Ubiquitous Web Domain Lead
