No.  At least, that is not what Unisys claims.  Unisys asserts that their 
patent covers decompression (I assume that's what you meant to write.) I 
was told this directly by Oliver Picher, spokesperson for Unisys on the 
LZW issue.

Now, they may be wrong, or not telling the truth, or hoping that nobody 
challenges them.  But they do assert that decompression is covered.
