Intel Corp now faces a flood of lawsuits over its failure to warn of the Pentium flaw in timely fashion: one of the lawsuits is a class action filed by the San Francisco firm Lieff Cabraser & Heimann on behalf of several individuals and charges Intel with unfair business practices, false advertising, violation of the consumer protection statute, breach of implied warranty and negligence; the other lawsuits mainly allege securities fraud but the state attorney general of Connecticut, Richard Blumenthal, warned Intel officials in a letter that its handling of the affair may have violated his state’s unfair-trade-practices law and similar lawsuits have already been filed in California, Michigan and Illinois.
