The European Commission announced on Monday that it will begin formal investigations into allegations that IBM has abused its dominant market position in mainframe computers.
The Commission, Europe's main antitrust authority, said that it would look into two separate cases of alleged infringement of the E.U.'s antitrust rules. Both cases are related to IBM's conduct in the mainframe computer market.
The first case follows complaints by emulator software vendors T3 and Turbo Hercules who claim that IBM is tying its mainframe hardware to its own operating system. Emulator software allows the computer to run software that it would not normally accommodate.
The second case is being brought by the Commission itself over IBM's alleged discriminatory behavior toward competing suppliers of mainframe maintenance services.
