Dependent claims 

No objection on account of lack of unity is justified in respect of a dependent claim and the claim on which it depends (see F‑V, 2.1).

If, however, the independent claim appears not to be patentable, then the question whether there is still an inventive link between all the claims dependent on that claim needs to be carefully considered (see F‑V, 4.2).

For a definition of a dependent claim, see F‑IV, 3.4, and F‑IV, 3.8.
