34Second, it should be noted that, according to recitals 4, 5 and 9 in the preamble to Directive No 469/2009, the SPC is designed to re-establish a sufficient period of effective protection of a basic patent by permitting the holder to enjoy an additional period of exclusivity on the expiry of his patent, which is intended to compensate, at least in part, for the delay to the commercial exploitation of his invention by reason of the time which has elapsed between the date on which the application for that patent was filed and the date on which the first marketing authorisation in the European Union was granted (see, to that effect, judgment in Actavis Group PTC and Actavis UK, C‑443/12, EU:C:2013:833, paragraph 31 and the case-law cited).
