Form 1200 may be filed electronically using EPO Online Filing (OLF), the EPO case management system (CMS) or the EPO Web-Form Filing service. The (basic part of the) filing fee is reduced if Form 1200 is filed online (see point 5.7.003).[ 32 ]

If filed in paper form, either by post or by fax, only one copy of the document must be submitted. If the form is filed by fax, a confirmation copy must be filed only on invitation by the EPO. 

The IB sends to the EPO as designated/elected Office a copy of the international application and the ISR, any claims amended under Article 19 PCT, as applicable, as well as the International Preliminary Report on Patentability. The EPO is also informed when no meaningful search could be carried out or could only be carried out for some of the claims. Where a demand for international preliminary examination (Chapter II) was filed, the IB transmits to the EPO as elected Office the IPER, including any annexes. The IB will notify the applicant thereof, and the applicant himself should not file any of these documents with the EPO (see point 5.2.007). However, the applicant may have to file a translation of the international application and further documents as set out below (see points 5.5.001 ff).
