ACTA protests are continuing to spark unrest across Europe. On Thursday, hundreds of people took to the streets of Prague in one of the latest of many such protest events that have swept the E.U. as anger about the Anti-Counterfeiting Trade Agreement has spread and gained force.

Last week 22 of the E.U.'s member states signed the treaty in the face of massive protests in Poland and other countries, and the people of Europe continue to voice their opposition to ACTA, which they say would limit Internet freedom, censor Internet use, and quash innovation worldwide.

Described by some observers as SOPA's big brother (in a reference to the Stop Online Piracy Act shelved last month by the United States Congress in the face of crushing online opposition), ACTA is the latest anti-counterfeiting scheme to gain the attention of Internet freedom fighters from the Free Software Foundation to the Anonymous hacktivist collective.

proposed agreement that would create an international framework and set of standards for enforcing intellectual property rights, ACTA creates a voluntary legal regime that countries may choose to join. It creates a governing body outside of the United Nations and other international institutions, allowing for copyright and intellectual property cases to be adjudicated across national lines without having to contend with conflicting national laws and legal schemes.

The ACTA protests look poised to continue for months, as the treaty is not slated to go into effect until at least June.
