The EPO’s 10-day-rule will be abandoned from 1 November 2023. A safeguard mechanism will be effective in case a document is received late (more than 7 days late), with the burden of proof in case of disputed notifications being with the EPO. The new regulation applies to documents notified on or after 1 November 2023. See OJ EPO 2023, A29 for more details and some examples.
