I am looking our Unisys license agreement now...... Their patent (US
4,558,302) is on the LZW compression/decompression algorithm used in GIF,
TIFF, etc. But the license doesn't seem to make any distinction between
LZW and GIF. IMHO you should be OK using GIF as long as you don't use
LZW. But, then you might as well use PNG now that it is supported in Java
1.3 and browsers ;-)
Some products (like RougeWave.com's charts) ship GIF functionality w/o a
license, but if you want the GIF compression turned on, you have to send
them your Unisys License agreement.
The Unisys lawyer we spoke to seemed to think *any* use of GIF w/o license
of some sort is unlawful or at least a gray area.
Go PNG!!!!!!
