I believe I read somewhere that the Fuji Roubaix actually used the name first, but that didn't stop Specialized from trying to sue over it because they thought the existence of an entry level road bike with the same name as their higher end bike hurt their bike's value, but it didn't get very far. Again, I just read that on the interwebz, so it should be taken with a grain (or 12) of salt.
