1. Introduction 

Documents filed with the EPO may contain errors, e.g. in the bibliographic data, the description, the claims or the drawings (see H‑VI, 2). Errors may also occur in the decision to grant or other decisions of the EPO (see H‑VI, 3), in formatting/editing (see H‑VI, 4), as well as in printing the specification (see H‑VI, 6).

These errors can be corrected as set out below.
