3.12 Lack of unity 

Where the claims do not relate to a single invention only ‒ or to a group of inventions that are so closely linked that they form a single general inventive concept ‒ the search will normally be restricted to the invention or linked group of inventions first mentioned in the claims (see B‑VII and F‑V, 3.4). If the search is restricted this way, the applicant will be informed in a communication accompanying the partial search report (see B‑VII, 1.2).
