The difference between Monster and the two examples you gave Wayne is that Coca-Cola and Harley Davidson are not common phrases that are used outside of references to the cola and motorcycle respectively. It seems like Monster Cable is trying to take ownership of a common everyday word that has been around since the start of time. Other companies and shows such as "Monster Homes", "Monster Garage", "Monster Inc." are using the word in its intended way with no reference to cables and yet legally, they are being challenged. That's just gross.
