The paper reported Friday (July 1) that Ronald Konieczka of Cincinnati, Ohio, and Maria Prohias of Miami filed the suits in San Francisco, alleging that Intel has engaged in anti-competitive practices resulting in higher priced computers and other electronics products. Konieczka and Prohias, each represented by Los Angels law firm Hagens Berman Sobol Shapiro, have asked the court for unspecified restitution, according to the Mercury News.

The class action suits come just days after rival Advanced Micro Devices Inc. (AMD) filed an antitrust suit against Intel in a U.S. District Court in Delaware on June 27, alleging that Intel has been operating an unlawful monopoly in the x86 microprocessor market.

Intel responded with a statement June 28, saying it "strongly disagrees" with AMD's complaints and vowed to fight the suit in court. Intel President and CEO Paul Otellini later affirmed his company's stance, saying in a statement that Intel would not change its business practices and expects any court decision to be resolved in its favor.

The following day, AMD filed two lawsuits in Japan, alleging violations of Japan's Antimonopoly Act.
