I am not certain , but I think terse uses a modified Lempel-Ziv algorithm, either patent number 4,814,746 or 5,001,478. IBM owns both. The details of the patents can be seen at http://www.uspto.gov/ (click on "search" under patents, and on the next screen click on "patent number search", and on the next screen enter the patent number and click on "search". The second patent inventor's name shows up on the help screen of the OS/2 terse program, and in the messages of the VSE terse program (messages which I saw in a VSE listserv post). I read somewhere that terse uses the algorithm in the first patent.
