Perhaps that paragraph doesn't make it clear. I've never been sued by
Unisys (or anyone else) but it seems clear from e-mail communication
with them that they considered plug-ins like Gimp TIFF to be in
violation of their LZW patent, regardless of how LZW is implemented
inside the plug-in.

In theoretical terms, I do not know what legal precedents exist in the
US or in my home country (Great Britain) so I cannot say whether a
court would consider the violation mine, libtiff's or both...

In practise, as I have said elsewhere off list, it doesn't matter. If
they haven't done more than write unfriendly e-mail in the past I see
no reason to expect different in the future. Bringing cases to court
would only highlight the unfairness of algorithm patents, which is
not in their interest.

This isn't really on-topic for gimp-devel, so I suggest you take any
further discussion off the list. From the graphics point of view,
adequate or even better replacements for LZW TIFF already exist.
