Apple paid Swiss Federal Railways $21 million after the transport company accused Apple of ripping off its clock design for the clock on new iPads running iOS 6, according to Mashable. The company noticed its clock was being used without permission in September:

Initially, Swiss Federal Railways threatened to push for legal action, but within a few weeks, Apple seemed to give into pressure and agreed to license the clock’s design.
