The Software and Information Industry Association (SIIA) has filed its first software piracy lawsuits in Europe.
The cases were filed on behalf of SIIA member Adobe Systems as part of a new European anti-piracy campaign.
The SIIA expanded its Internet Anti-Piracy Program into Europe in January, when it began monitoring internet sellers in the region.
The first cases were filed against online sellers in the UK and Germany for allegedly selling counterfeit or unauthorised copies of Adobe software on eBay.
"These lawsuits represent a new front in our war on software piracy," said Keith Kupferschmid, senior vice-president of IP policy and enforcement at the SIIA.
"The SIIA has successfully tracked and pursued hundreds of US software pirates, recouped millions of dollars for our member companies, and, in some cases, put the culprits in jail," he said.
"With monitoring and enforcement underway in Europe, SIIA is now working to stop software pirates who swindle consumers and companies around the globe," said Kupferschmid.
In the past three years, SIIA has filed more than 100 lawsuits against illegal sellers using eBay as well as sellers on other websites dealing in counterfeit, OEM, academic, and other illegal software.
