Patently Apple reports that Apple acquired the Lightning trademark from a motorcycle maker Harley-Davidson. Details of the trademark deal were made public in a filing with the European Union and it noted that the registered trademark for “Lightning” was originally owned by H-D Michigan, Inc, which is the intellectual property holding company for Harley-Davidson.
Harley-Davidson originally owned the rights to the trademark across a wide range of product types: television sets, games, computer game programs, eye glasses, and eyeglass frames, in addition to motorcycle electrical parts, protective helmets and turn signals.
The Lightning connector was first introduced on the iPhone 5 in September, which replaced the 30-pin dock connector found on previous models. It is 80% thinner than its predecessor and also orientation independent.
