Protests have been as much virtual as in the flesh. An online petition calling for the rejection of ACTA has been signed by more than 1.75 million people. Hackers have also targeted websites supporting the agreement.
Industry bodies are concerned about ACTA's scope. "It would be a sad day for the European Internet industry if the [EU] parliament rushed on this," says Andrea D'Incecco, public affairs manager for EuroISPA, a group representing European Internet service providers.
Mr. D'Incecco says ACTA would change European law, which currently requires a court order to be served on ISPs before they take action against unlawful online material. He also says the "secrecy" of the negotiations, initiated by the European Commission but until recently excluding the EU parliament, is a problem.
