I support the application for a trademark in principle (subject to cost).

I think trademarks and copyright are appropriate protection for
software/informatics works rather than patents (there is strong feeling
against software patents in many quarters). [I have gone through this in a
non-crystallographic field of informatics]. The positive aspects are that a
trademark can help to promote an image of quality which is entirely
appropriate for an International Union, and to emphasise the technology in
a non-confrontational way. Trademarks are also very suited for validation
and quality control.

Both profit and non-profit organisations are increasingly seeing the
benefit of informatics standards and these might be required when
purchasing goods (e.g. equipment of information).

As always, this is ultimately testable in court. The organisation and
layout of information is also copyrightable as well as the content and it
could be argued that part of the copyright remained with the designer of
the layout (though it could be difficult defend). Thus if the CIF
dictionary is converted to a GIF, it could infringe the GIF IPR (actually a

I approve of this motivation. We have had far too many 'mutant' file types
in molecular science ("PDB-like files") and there is a lot to be gained by
having examples of ones that are monitored and where there is a stick and
carrot to enforcement. In particular it puts an onus on suppliers of goods
to be sure that they are honouring the standard rather than guessing or

Trademarks can be registered for certain classes and within the first year
(in Europe) other trademark holders have the right to object to the use in
specific domains.

I think this is very valuable. In the Internet world there are services for
validating HTML (and shortly, XML). Some of these can be accessed remotely
(e.g. uploading of documents to a server for analysis). Also there are
conformance-testing sets - files which test whether software is compliant.
A tool that purports to read CIF should be tested against a wide spectrum
of conforming (and also deliberately non-conforming) test documents. There are
many "special cases" which occur occasionally and which are important to

I am a supporter of OpenSource (and distribute much of my software this
way) but don't feel this is not incompatible with trademarks - especially
from a non-profit org.
