Johnson v. Microsoft Corp.

Ohio Supreme Court

Decided October 5, 2005No. 2004-0304PublishedCited by 179 opinions

1Opinion of the CourtO’Donnell, J.

{¶ 1} The principal issue for our consideration on this appeal concerns whether plaintiff-appellant, Maria Johnson, who purchased a computer from Gateway, Inc., containing a Microsoft Windows 98 operating system, may file a class action lawsuit against Microsoft Corporation for monopolistic pricing of its software in violation of the Ohio Valentine Act. After careful consideration, we have concluded that Johnson, as an indirect purchaser of Microsoft’s operating system, may not assert a Valentine Act claim for alleged violations of state antitrust law.
