A naive' question that's probably been answered long ago:
When Terry Welch wrote the old Unix "compress" program, his employer
patented his improvement on Lempel and Ziv's compression algorithm. I
understand this patent is now owned by Unisys.
Does the Lempel-Ziv-Welch compression used in NOS compressed SMTP service
infringe upon this patent?
