More than $4 million from the settlement of a Microsoft class-action lawsuit will go toward computer science education in Iowa schools, according to the office of Des Moines attorney Roxanne Conlin, who represented Iowa consumers and businesses in the lawsuit. The funding will come from a 2007 court-approved settlement of a class-action antitrust lawsuit filed against Microsoft Corp., alleging that the company overcharged Iowa consumers and businesses for certain products. The nearly $180 million settlement agreement included setting aside a portion of unclaimed money to buy computers and software for Iowa schools. The $4 million announced today will be administered over three years through the Iowa Department of Education. Specific projects are in the planning phase, and implementation is expected to begin within the next six months, according to Conlin’s office.
