Apple has acquired the trademark "Lightning" from motorbike makers Harley Davidson, but only for use on a limited set of goods and services, a European trademark filing has revealed, according to The Register.

The financial terms of the deal were not disclosed.

Apple was granted two European registrations for the "Lightning" trademark last week. The legendary motorbike brand only partially transferred the trademark to Apple, which means it could use the Lightning name in the future.

Cupertino is using the name for its Lightning connector, a super-fast data and power link introduced in September for the latest iPhone, iPads and iPods, replacing the usual 30-pin connector.

Apple's first registration covers eyeglasses, goggles, wiring, voltage regulators, audio and video equipment, computer software and other gear.

The second registration covers the use of the word Lightning for "goods or playthings".

Harley Davidson's intellectual property arm is HD Michigan, which is listed on the trademark.
