The company called Aviv Nevo, a University of Pennsylvania economics and marketing professor, to rebut claims made by FTC experts.
Nevo testified that the FTC's theory that Qualcomm uses its power in the chip market to charge excessive royalty rates "is just not born out of actual market data." He noted "there's no support for the theory in the data." Nevo also testified that the mobile industry is strong and that Qualcomm had legitimate business reasons for its licensing policies.
