LZW/GIF licensing issues

The GNU no gifs page gives a strong argument against using the industry standard GIF image file format. Their argument is based mostly on the fact that IBM and the IT corporation Unisys own patents on the LZW compression algorithm used when creating images using the GIF.

In 1999, Unisys sued several web companies for incorporating unlicensed GIF/LZW technology while developing their websites. A complete account of this story can be viewed at this webpage, a product of the League for Programming Freedom at the MIT AI Lab.

The expiration date for the Unisys patent on LZW was June 19, 2003! See this website for a good historical account of the GIF/LZW controversy.
