That's not the point. (Score 2)

It is is immoral for Unisys to hold a patent on the LZW compression algorithm in the first instance, and even more immoral for them to charge $5000 for `unlicensed' images.

Patents are supposed to protect small-time inventors and operators, not be a bargaining chip for multinationals to use to bully people (which is just what this is---pure extortion on Unisys's part.)

I've seen many people talking about Unisys's inability to prove an image was generated with unlicensed software; this double-edged sword means it's impossible for someone who wants to become compliant to know where ver GIFs came from, so they'll have to be re-created, or cough up the $5000 fee.

The answer? Realise Unisys's patent and subsequent ``offer'' for what they are: further abuse of the patent system to get a few more dollars from an idea that just simply isn't worth what they're asking.
