SAN FRANCISCO, April 17 (Reuters) – Apple Inc and Qualcomm Inc on Tuesday settled an acrimonious two-year legal dispute. Shortly afterward, Intel Corp said it will exit the smartphone modem chip business.

The entire drama played out as the mobile phone industry prepares to shift to a technology called 5G.

Echoing complaints from the U.S. Federal Trade Commission, Apple had alleged that Qualcomm used its patent licensing business to keep a monopoly on modem chips that connect devices like the iPhone to wireless data networks. Qualcomm insisted that Apple was using its valuable technology without proper payment, and Apple later dropped Qualcomm’s chips in favor of those from Intel.

In the end, Apple and Qualcomm ceased all litigation,
