2.3 Requirements as to form 

Decisions taken by the examining or opposition divisions must be in line with the principles set out in E‑IX, 1 E‑X, 1. Where a decision is produced on a computer, the copy put on file contains the name and the actual signature of the employee (or employees) responsible.

If, exceptionally, one or more division members cannot sign the decision, e.g. owing to extended illness, only a division member who was present at the oral proceedings (preferably the chair) may sign it on their behalf (see T 243/87). A brief written explanation as to why one member is signing on behalf of another must be provided (T 2348/19). A written decision signed by someone who did not take part in the oral proceedings at which the decision was pronounced is not legally valid (see T 390/86).

The presentation of the facts and the submissions, the reasoning and the information on the means of redress are generally omitted when a decision merely meets the requests of all the parties concerned; this applies in particular to the decision to grant, which is based on documents that the applicant has approved (Rule 71(5)). The same applies when the patent is maintained in an amended form, because this is preceded by a final interlocutory decision under Art. 106(2) concerning the documents on which the maintenance of the patent is to be based (see D‑VI, 7.2.2).

The decision must be drafted only in the language of proceedings, in order to meet the requirements of Rule 111(2). Arguments of parties in another official language must be summarised in the language of proceedings. Deviations from this rule are possible in exceptional cases only, for instance where necessary to address questions of fact, evidence or law, e.g. in relation to witness statements.
