Please circulate to ITU management.
I am the person at Adobe responsible for TIFF. It has come to my
attention that rather than using finalized IETF specifications for
your TIFF based standards, the ITU publication (T.37) of the set of
standards commonly referred to as TIFF FX (RFC 2301) preceded the
IETF's final publication. Unfortunately, I must inform you that TIFF
FX, as defined by the IETF in RFC 2301 and in ITU T.37, is outside
the scope of the license grant provided both to the ITU and the IETF
in the fall of 1997. Other ITU efforts may also be affected.
Adobe has communicated ongoing concerns in this area to the IETF
editors/Xerox since the Spring of 1998. The Editors continued
progressing the document despite Adobe objections, thus Adobe
formally notified IETF management in December 2000 and the issue was
elevated to the IETF's IAB in March of 2001. It was Adobe's
understanding from the IETF editors that the ITU was basing its work
on the IETF's work and that communication with them was sufficient.
This issue is currently being considered by the IETF Internet Fax
working group and has yet to be resolved.
Since the IETF standard and any adoption/implementation of TIFF
FX--including ITU standards based on TIFF FX--is out of scope of
Adobe's 1997 license grant, please rescind publication of the
standards based upon RFC 2301 until these standards are brought
within the scope of Adobe's license. This would include T.37 and
other TIFF FX based efforts.
Adobe understands that the IETF specifically declines to take a
stance on IP use in its standards and thus defers decisions on the IP
status of technology in its standards to the members of its working
groups and those who choose to adopt/implement their technology, and
whatever internal processes these companies/organizations have for
evaluating the IP of technology they choose to include in their
products or support in standards. Thus, the ITU's mere use of IETF
standards does not imply compliance with an Adobe TIFF license.
Finally, please notify SG16 and other affected parties. Since Adobe
is a supplier of copyrighted work to the ITU under license and not a
participant in the working group, it is not apparent how we may
contact the various participants and parties directly.
I am confident that Adobe can reach an agreement with those wishing
to make use of TIFF in the development and use of TIFF FX. For
instance, at the IETF's request, Adobe has provided a means whereby
third parties may submit candidate extensions to TIFF that-if
approved-would bring TIFF FX within the scope of Adobe's existing
license grant. Adobe does not have the IP rights to include these
extensions unilaterally. And this mechanism has yet to be utilized.
Further, Adobe has participated in recent IETF interoperability
discussions that may result in splitting TIFF FX into two standards:
one with existing interoperability that can be progressed rapidly and
has the side effect of being in scope of the Adobe license, and one
that lacks both interoperability and being in-scope of Adobe's
license. This would imply deferring publication/adoption of the
latter parts. Other options are certainly possible.
I am committed to work with the groups involved to explore these and
