Rather than bend to Apple's demands, Qualcomm countersued. Apple sued back. There were more than 80 lawsuits between the two companies in Asia, Europe and the United States. The dizzying number of legal cases has turned acrimonious. Qualcomm has accused Apple of stealing trade secrets and handing them over to rival Intel, which has supplied wireless chips in recent iPhone models. Intel shares fell about 80 cents, about 1.5 percent, after news of the settlement. But Intel's stock finished the day up 43 cents nonetheless. As the price of an iPhone has increased to levels once unheard of in the wireless market, Qualcomm has been able to command larger payments for its patent portfolio - a fact Apple finds particularly irksome. Unlike other handset makers, Apple managed to negotiate its fee to about $7.50 per unit, according to court filings and a person familiar with the matter. That's a price Apple still believes is too high. Qualcomm says it bundles its patents to simplify the process.
