Just to add to the above, a utility patent also has to have an invention. The new use for an old something has to be novel and non-obvious. Again, using the wheelbarrow analogy, if I wanted to patent the use of wheelbarrows for something different such as being a mobile platform to stand on so I can reach up higher that use has to be a new one that it was not used for before (i.e, no prior art) and it has to be non-obvious so nobody had ever thought to move the wheelbarrow over to that wall and stand on it to reach the light fixture and change the lightbulb.
