    Hi Harry,

    Thank you for your response to my earlier e-mails. Nothing has
    changed in the Adobe position.

    The IETF and ITU use of TIFF in RFC 2301 and T.37 is out-of-scope of
    the license we granted to each organization. Other than use under
    this license, the ITU and IETF may not use TIFF. Likewise, the IEEE
    may not use TIFF to develop new standards without a license from

    This license granted to the IETF restricts IETF use in several ways.
    Two examples of these require use to be based on a published TIFF
    specification and not to inhibit future Adobe use. I must refer you
    to the license granted the IETF for a complete listing of the
    requirements. RFC 2301 and T.37 fall outside the scope of these.

    A technical result of their efforts being outside-the-scope of the
    license is that TIFF and TIFF FX are not interoperable (in all but
    the 'S' profile).

    IEEE selection/adoption/propagation of TIFF FX would promote/endorse
    an IETF document that is out-of-scope of the license Adobe granted
    the IETF and ITU. Regarding a potential license that Adobe could
    offer the IEEE, Adobe would most likely consider a similar license to
    the one granted the IETF and ITU. Note that this would only allow
    the IEEE to develop TIFF based standards that were interoperable with
    a published version of TIFF.
