In 2007, Apple announced the original iPhone, setting the tech world ablaze. The only issue was, Apple’s iPhone wasn’t the first iPhone. Cisco Systems had previously released another phone product with the same name, and sued Apple for violating their trademark.
Winner: Apple. The two companies settled out of court, and Apple never ultimately delivered on Cisco’s request that it make the two products interoperable. Today, the only iPhone anyone knows about is the kind with a fruit on it.
