Please do not confuse IP protection with the patent system. For example I love the copyright system while I hate the patent system. You don't copy code accidentally and to use your example - it's still relatively easy to research if names are already used and you don't have to do that often. But you have a really hard time figuring out if you break some patents while developing software. Even lawyers and courts often have a hard time figuring out if something steps on a patent or not. As software developer where you develop new things every day you can basically only close your eyes and code on hoping you don't trigger too many patent mines. Patents belong as little in writing software as they belong in writing other things like books, articles or speeches.
