Chapter 1. Measures of inquiry

Section 1.1. Purpose of instructional measures

The instruction is the administration of evidence by the EPO.

In fact, there are certain cases where it is necessary to prove facts alleged by the parties (eg an oral disclosure whose context or content is not known with certainty). E-IV 1.2 Directives).

This instruction can be (R117 EPC):

  • requested by a party;
  • decided by the EPO.

In the event of a challenge to a certificate, it is generally appropriate to grant a request from a party to hear the witness, before these statements are based on a decision that is unfavorable to the party challenging them (T474 / 04).

Section 1.2. Different measures possible

The possible instruction measures are (A117 CBE):

  • the hearing of the parties;
  • the request for information (eg request from a publisher to know the date of publication of a book, E-IV 1.2 Directives);
  • production of documents;
  • the hearing of witnesses;
  • expertise;
  • the descent on the premises;
  • written statements made under oath.

Nevertheless, this list is not exhaustive (E-IV 1.2 Directives).

Chapter 2. Preparation of the instruction

Section 2.1. Procedure during which an instruction can be carried out

An investigation may be conducted in any proceedings before the EPO (A117 CBE, the old A117 CBE73 referred to a defined list).

Nevertheless, the measures of instruction are rare and are mainly used in opposition (E-IV 1.1 Guidelines).

Section 2.2. Competence to carry out this instruction

The investigation is carried out by the competent authority for the procedure (eg opposition division, etc.).

The competent division may instruct one of its members to proceed with the measures of inquiry (A117 (2) EPC together R119 (1) EPC): this is especially useful when a field trip is necessary in order to see, for example, the operation of a machine (E-IV Guidelines 1.3).

In order to obtain "swearing" or other binding declarations (ie criminal sanctions for falsehoods), it is necessary for the EPO to request the competent judicial authorities of the State (A131 (2) EPC) in which the person concerned has his domicile to hear him under these conditions (R120 (2) EPC).

Section 2.3. Decision ordering the instruction

All the measures of inquiry are subject to the discretion of the court, which orders them only if it deems it necessary (T798 / 93).

A decision is made to this effect (R117 EPC).

This decision is served on the parties (A119 EPC).

An independent appeal is not possible against this decision, but can be brought at the same time as the appeal against the final decision (A106 (2) EPC and E-IV Guidelines 1.4).
