His litigation strategy-building capabilities are unique I think. He is a charismatic person, with assertive communication skills who is able to convince people easily.’

Peter Bibók: Peter has a very good insight into the IT industry and technological trends which is rare among lawyers. He is able to bridge legal thinking with IT knowledge thus he can “translate” very complex IT cases to judges who are by far not knowledgeable in IT practice.’
