In late 1992, Daniel Sleator, professor of computer science at Carnegie Mellon University, took over management of the ICS. He addressed, among other issues, the frequent complaint that players would lose blitz games on time due to network lag. In 1994, he copyrighted the code, and began receiving purchase offers from companies wanting to commercialise the server. There were questions about whether Sleator was right to claim that the ICS was his intellectual property, since he did not code the original server, although he had made substantial improvements to its code.
