Re: LPF Statement on the GIF controversy (LZW patent)

In order to protect the validity of a patent, the holder is obliged to try to
enforce it in an essentially non-discriminatory manner.  While Unisys is not
required to go out and sue users and developers of freeware, they are precluded
from explicitly saying, "You freeware guys, forget it.  We're only worried
about people who are making money."

The reasonable practice with freeware, I would guess, would be for Unisys to
demand an acknowledgement in the software or documentation of their patent
claim, thereby saying that the freeware is produced under a license.  Unisys
doesn't have to collect money or prohibit the use of their patented material in
freeware, but I can see them demanding an acknowledgement of their claim as the
condition for license.  That would actually put software such as KA9Q in a very
awkward position, which would be the intention.
