As to why Apple -- and not Intel -- is filing for the Thunderbolt trademark, no clear explanation has been forthcoming from either company so far. It is possible that Apple has decided to use the Thunderbolt name for it's own implementation in order to differentiate it from others, such as Sony's alleged USB-based version of Thunderbolt (which may run afoul of the USB Implementer's Forum), a situation not dissimilar to the split between Firewire (the trademarked name for Apple's technology) and Sony's use of the term iLink, both referring to the same standardized technology, which was eventually given the formal name IEEE 1394.
