Oh, and by the way, software patents are not valid in Canada, so this patent would only apply to hardware that does LZW compression. 06/19/2003 07:02:33 PM EST (>2. 06/19/2003 10:37:20 PM EST (>4. How much money did Unisys actually make from this? Especially from software developers. I hope this fucking hurts, you assholes. Huzzah for all internet users everywhere (except Unisys employees, who

This creates an interesting legal situation where LZW-based sofware is legal to distribute in the United States, but risks patent infringement claims in or when exported to Europe, Canada and Japan. hasn't diminished GIF's popularity

Call me paranoid, but I'm not rushing to use GIFs again. One of the products I work with could definitely benefit from this being public domain now, but I'm just waiting
Center) and the Burroughs Corporation merge to form Unisys. 15th June 1987>: Bob Berry and the team at Compuserve release a new graphics file format called GIF (Graphics Interchange Format). It can handle anything from 2 to 256 colours -- wow! -- and the graphics data is compressed with LZW. Just like Spencer, they had read the LZW algorithm in a magazine and had wrongly assumed that it wasn't patented. The GIF format becomes even more popular. tries to bring up the issue in public. Unisys have been ensuring hardware manufacturers (e. modem manufacturers and Postscript printer manufacturers)
and method", it is more commonly known as the LZW patent or Unisys's GIF tax. Don't buy ram at Apple. You can save big money when you buy your memory at MacMemoryStore. Most popular compression techniques build on this technique and most archivers (e. ZIP, ZOO, ARC, gzip, LhA, CAB, Arj, RAR, StuffIt) include it in their compression methods. I only mention this to tell you it's unrelated to LZ78 or LZW. [US4,464,650]>), but the LZW derivative is widely used. Terry Welch has been working for the Sperry Research Center and invents a derivative of LZ78 with much simplified, faster dictionary
