Patents IMO work better when it's a physically instantiated implementation of a very specific task. The big issue is where we've gone with software patents that are little more than "a server talks to another server and requests information from a database". Those implementations are extremely vague and cover way too much ground. Like the game patent that covered the entire idea of having a playable game during a loading screen or at least pretended to and the idea of fighting it was too expensive to bother trying to force the issue.
