One does not patent an algorithm. One patents an invention that utilizes the algorithm. I don't find it puzzling that Unisys and IBM came up with two different inventions that use the LZW algorithm. It is possible that the two patents interfere, but obviously neither patent owner has seen fit to do anything about it if they do. Unless you have evidence that IBM's patent applies to something we distribute and that there is reason to believe that they are likely to enforce it against us or our users, I see no reason to be concerned. I have no doubt that Debian contains hundreds of potential infringements of IBM patents. -- John Hasler -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
