Prosecutor Ricardo Saenz said his initial probe followed a complaint by Maria Kodama, the widow and only heir to the rights of one of the greatest Spanish-language writers of the 20th Century.
Saenz said Taringa! and the Portal Planeta Sedna "constantly and systematically violate intellectual property."
Taringa! issued a statement saying that it's open to an out of court settlement, and meanwhile has technology that can "reduce practically to zero" any exchanges of unauthorized content on the Argentine site.
