Apple's move to demand manufacturers to pay a licensing fee to carry the "Made for iPod" mark has annoyed some high-profile partners.

The company appears to want 10 per cent of all revenue in order to carry the mark and to connect to an Apple iPod port.

Bose and Altec Lansing are the latest firms fuming about this move. Dominique Walker, head of Bose's Asia-Pacific operations said: "All Apple partners were told of the decision some weeks ago. This is a massive licence fee which will not sit comfortable with many partners. Bose is not happy as the proposed fee is excessive by any standards."

An Altec Lansing spokesperson called the tithe "ridiculous and excessive" warning: "It will result in many partners re-thinking their relationship with Apple. It will also push up the cost of Apple accessories."

Apple has been cooking up its licensing scheme for some time.
