[JURIST] European antitrust investigators raided Intel Corp. [corporate website] offices in Britain, Germany, Spain and Italy Tuesday as part of an ongoing probe of the chipmaker European affairs by the European Commission, which over the last four years has been looking into allegations that the computer chip giant used unfair business practices to encourage client's to purchase its microprocessors. The raids come some two weeks after rival Advanced Micro Devices (AMD) [corporate website], filed federal anti-trust lawsuits [US complaint, PDF] against Intel in both the United States [JURIST report] and Japan [JURIST report]. The EU decided to continue its investigation in March when Japanese investigators announced that Intel violated anti-trust restrictions there. Intel has denied all allegations of wrongdoing. AP has more.
