The US also allows implementation patents so you can take any existing patent and add "using a computer" to the end.
For instance, placing a small dot to mark the end of a sentance - on a computer, is a new patent.
Small graphics that depend on other data in the document and are updated when that data is changed, to be a bit more precise. Still pretty obvious, of course.
