Stefan,
        Our reading of this allows the use of LZW without licence in

countries where the patent has expired. If you export to a country where it the patent is still in force then we believe a licence is still required and it would be advisable to contact Unisys.

There aren't any more such countries. The last Unisys LZW patent expired on July 7, 2004.

For as much information as you could ever want on this topic, please see

and the associated thread.
