Mediaset is pursuing cases against 19 digital operators that it believes has breached its copyright.
Previously it has also successfully defended itself against Facebook, Yahoo and Dailymotion.
Earlier this week, a Rome court ordered Dailymotion to pay Italy’s Mediaset €5.5 million for breaching copyright law.
Vimeo is said to uploaded clips of close to 498 Mediaset shows without prior permission.
Mediaset believes it could be liable to pay compensation of almost €200 million.
