IPI fax numbers to be discontinued from 1 January 2020
The IPI will discontinue its fax services at the end of 2019. The reason for this is that the IPI’s telecommunications provider is switching from analogue telephony to the Internet Protocol (known as All IP). As a result, faxes would be susceptible to errors and the complete transmission of messages and documents would not be guaranteed.
Email and post are offered as alternative means of submission. For Swiss and international trade mark applications, we recommend that applicants use the electronic application systems e-trademark and IR-Online.
It is also possible to send submissions by email. To be considered legally-binding and in observance of time limits, however, they must be sent to a specially designated email address. You can find further information on electronic submission on the IPI website.
