Do I receive a fee reduction if I make use of the Contingency Upload Service?

The existing fee regulations for filing in electronic form also apply to the Contingency Upload Service.

In case an international application is filed using the Contingency Upload Service, the international filing fee is reduced by 100 Swiss since this filing is done in electronic form but the request is not filed in character-coded format.
