Every application must designate the inventor. The designation is incorporated in the epoline^® Online Filing software. When filing on paper, the designation is filed in a separate document where the applicant is not the inventor or the sole inventor; otherwise the designation must be effected in the Request for Grant form by placing a cross in the appropriate box in Section 22. Where the designation is effected in a separate document, a trilingual form available free of charge from the EPO or the central industrial property offices of the Contracting States should preferably be used.
