I expect we can/should probably draft a standard disclaimer similar to: 

--- snip ---
This package uses LZW compression technology which Unisys claims to hold
US and forign patents over (including US #4,558,302).  Use of this
software may require licencing from Unisys.

Currently applicable information as to Unisys licensing policies for
products using LZW (GIF, TIFF-LZW, PostScript, Portable Document Format
(PDF), V.42bis, etc.) can be obtained by contacting the following: 

Welch Patent Licensing Department; Unisys; Mail Stop C1SW19; P.O. Box 500,
Blue Bell, PA 19424.  Via the Internet, send E-mail to
LZW_INFO@UNISYS.COM, or use a form available on the Contact Page of the
Unisys Web Server to request follow-up information. Via facsimile, send
inquiries to Welch Patent Licensing Department at 215-986-3090.

Note, of course, that I'm not a lawyer and I've just borrowed portions
from http://www.unisys.com/LeadStory/lzwfaq.html
