This antitrust class action lawsuit was filed by plaintiffs alleging a conspiracy involving ODD suppliers to fix, maintain, or stabilize the prices of ODDs at artificially high levels in violation of federal and state antitrust laws. ODD refers to a DVD-RW, DVD-ROM, or COMBO drive manufactured by one or more Defendants or their asserted conspirators. The cases are known as In re Optical Disk Drive Products Antitrust Litigation, No. 3:10-MD-2143-RS (MDL 2143). This lawsuit is brought on behalf of individuals and businesses who purchased a new computer with an internal ODD, a stand-alone ODD designed for internal use in a computer, or an ODD designed to be attached externally to a computer as residents of Arizona, California, District of Columbia, Florida, Hawaii, Kansas, Maine, Massachusetts, Michigan, Minnesota, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Mexico, New York, North Carolina, Oregon, Tennessee, Utah, Vermont, West Virginia, or Wisconsin between April 1, 2003 and December 31, 2008 for their own use and not for resale. Because the class here is end-users who did not resell their products, they are known as “indirect purchasers.” The defendants deny they did anything wrong.
