Renewal fees for a European patent may only be imposed for the years which follow that referred to in Article 86, paragraph 2.
Any renewal fees falling due within two months of the publication in the European Patent Bulletin of the mention of the grant of the European patent shall be deemed to have been validly paid if they are paid within that period. Any additional fee provided for under national law shall not be charged.
Amended by the Act revising the European Patent Convention of 29.11.2000.
