In a statement, IBM said it will not assert claims for server monetary damages for two years and will not seek to recover damages on such claims incurred prior to June 30, 2002. Microsoft also dropped antitrust claims versus IBM.
The settlement addresses discriminatory pricing and overcharge claims IBM made in the mid-1990s as part of the antitrust case. The claims related to the IBM OS/2 operating system and SmartSuite products, with the exception of claims for harm to IBM's server hardware and server software businesses.
In November 2003, Microsoft and IBM entered into agreements extending the statute of limitations on antitrust claims based on the U.S. antitrust case while exploring resolutions that would avoid protracted litigation.
Microsoft and IBM cooperate as much as they compete. The technology powerhouses work together in standards groups to facilitate the creation of Web services and other protocols that will ensure more efficient transactions over the Internet.
But the companies also compete on a cutthroat level in middleware, such as application servers.
Microsoft's Exchange Server often finds itself going head-to-head with IBM's WebSphere Application Server when it comes to new accounts, though the arguments are generally settled when a customer decides to work with either Microsoft's .NET environment or IBM's Java software.
Putting the current legal malaise behind them can only reinforce both the cooperation and the competition.
''With these antitrust issues behind us, both Microsoft and IBM can move ahead, at times cooperatively and at times competitively, to bring the best products and services to customers,'' said Brad Smith, general counsel and senior vice president, Microsoft.
