2. Opposition after surrender or lapse

An opposition may be filed even if the European patent has been surrendered or has lapsed for all the designated States. This is relevant in that in such cases the rights acquired with the patent remain in existence during the period up to surrender or lapse and claims arising from such rights may subsist after that date.
