have to pry the GIFs from my cold, dead fingers. i always found it amusing that the other side used gifs instead of pngs despite bleating about how bad patents were. 06/19/2003 05:18:36 AM EST (>4. 06/19/2003 06:01:53 AM EST (>4. 06/19/2003 01:21:30 PM EST (>5. 06/19/2003 05:05:53 PM EST (>3. 06/19/2003 05:59:40 AM EST (>3. 06/19/2003 06:38:05 PM EST (>3. 06/19/2003 01:38:09 PM EST (>2. invented new compression techniques>, had them stolen by patent, and gave up the field. 06/19/2003 08:43:12 AM EST (>3. 06/19/2003 10:23:18 AM EST (>3.

The GIF format becomes even more popular. So the US patent has expired. covers Germany, France, Britain and Italy and expires on the 18th June 2004. expires on the 6th June 2004. 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

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
