Qualcomm’s rebates had, in actuality, anticompetitive effects, and this was
demonstrated in the changes in purchase of non-Qualcomm chips after the
rebates were offered. According to the graphs shown in the written decision of
the KFTC, the use of non-Qualcomm chips remained less than 6% during the
period of the rebate offering, and the percentage plunged to the 0% range after
Qualcomm changed its rebate structure.
