== ''USL v. BSDI'' lawsuit ==

In late 1991, AT&T's [[Unix System Laboratories]] (USL) brought a [[USL v. BSDI|lawsuit against BSDI]], alleging that BSD/386 contained their proprietary trade secrets and source code. When USL were acquired by [[Novell]], a settlement was reached in January 1994. BSDI agreed to base future releases of the product, now called BSD/OS, on the CSRG's [[4.4BSD-Lite]] release which was declared free of any USL intellectual property.<ref name="McKusick" /> Rob Kolstad (of the University of Illinois and Convex Computer Corporation) was president of BSDI during this period and headed the company until the close of the decade.
