A client list and information on clients’ computer networks do not qualify as trade secrets under the Illinois Trade Secrets Act, the Fifth District Court of Appeal decided April 13 in a business trade secrets lawsuit. In System Development Services v. Haarman, No. 04-CH-30 (Ill. 5th 2009), System Development Services (SDS) sued four former employees who left to start a competing business offering networking services to businesses in Effingham County. A trial court found that the defendants had misappropriated a list of clients and potential clients, as well as information on SDS clients’ networks, but the Fifth District Court of Appeal overturned that decision.
SDS sets up and maintains computer networks for local businesses. It maintains a database of clients and potential clients, and stressed to employees that both the list and the clients’ network information should be kept private. Defendants Timothy Haarman, Jason Repking, Rick Hoene and Terry Oldham left SDS after a bad financial year and started a competing business, Technical Partners. None had signed a restrictive covenant limiting their right to compete with SDS. However, when starting out, they sent out a mailing to potential clients that SDS thought was suspiciously similar to addresses in its client database. They also relied on former SDS customers during their first month inbusiness. SDS sued them for violations of the Illinois Trade Secrets Act and breach of fiduciary duty.
At a bench trial, the plaintiff testified that some of the addresses at issue contained information not found in the telephone book, and that work orders and emails were deleted from their system shortly before defendants left. However, the company’s owners told the court that they had no personal knowledge that a client list was stolen. The defendants testified that they made their mailing list using the phone book, the Internet and a chamber of commerce listing. They also relied on client relationships formed at SDS and personal connections. One defendant testified that no special knowledge other than the ordinary knowledge of a network technician was necessary to serve SDS and Technical Partners clients.
