that is a different style of a copywright issue, K2 was using those words and graphics in a manner that directly referenced the sex pistols, that is their inteluctual property, apple and apple are just nouns. if apple computers had used the same symbol or anything that directly referenced the original recording company to further their product they would be liable for damages. it was a rip off and k2 should have to pay, or halt the use, I don't think that what they were doing is part of fair usage because it is a direct reference.
