In the case of a patent document, a complete copy is supplied even if the patent is bulky.
In cases where part or all of the document is published only by electronic means (see Rule 68(2) and OJ EPO 2000, 367), an electronic version of at least those parts of the document not available in paper form will be made available to the applicant. This must be done in such a way that the applicant is provided with the whole document either in a combination of paper and electronic forms or in electronic form only.
