That's not completely true, at least as the system works. If there is something sufficiently innovative that it is "not immediately obvious to someone trained in the field", then it essentially qualifies as an invention. Inventions can be small and limited in scope as well as large. The real problem is in determining what is innovative enough that it would not almost immediately occur to most people trained in the field as an obvious solution to the problem. It is a subjective test, and IMHO, too many patents are given for things that really shouldn't pass that test. Patents can always be contested, but, it is a long and expensive process, so bad patents have a way of sticking around.
