Guide for applicants, Part 1: How to get a European patent

Unity of invention
European patent applications must relate to a single invention only, or to a group of inventions so linked as to form a single general inventive concept. In the latter case, multiple independent claims in the same category are allowed as long as they comply with Rule 43(2); but the more usual scenario is multiple independent claims in different categories (see point 85).
