The EPO's "10-day notification rule"

On and after November 1, 2023 the EPO's "10-day notification rule" will no longer apply to communications issued by the EPO.

Thus, if the EPO issues, for instance, a communication pursuant to Article 94(3) EPC on November 5, 2023, this communication will be deemed to be delivered on November 5, 2023. This date starts the four-month period for reply, which accordingly needs to be filed on or before March 5, 2024.

The 10-day rule will continue to apply to communications issued by the EPO on or before October 31, 2023.
