You don't even need to patch it to include a certain path, you can use (and I have used) it to include $ORIGIN or $ORIGIN/../lib in programs' RPATHs. Be careful about when this is and isn't okay though. When used wrong this can be a security risk, such as when your browser auto-downloads files to a Downloads folder, and the program you are patching is also in there.
