Microsoft is preparing 55 legal actions worldwide against sellers on auction sites who are hawking illegal copies of the company\u2019s software, the company said Tuesday.The actions are a mix of lawsuits and criminal complaints, said Jean-Christophe Le Toquin, a Microsoft attorney for Europe, the Middle East and Africa region. Microsoft has or will file 34 actions in Europe including Germany, France, Poland, Belgium, the United Kingdom\u00a0and the Netherlands.The company will seek prison terms for high-volume sellers and fines for less flagrant violations, Le Toquin said.Microsoft has stepped up its antipiracy campaign through legal suits. The company also sent out a program, Windows Genuine Advantage, to Windows computers that verifies whether the OS is a genuine, licensed copy. Microsoft said it has received tips from consumers who have been notified that their OS is not legitimate, and those customers have informed the company where they bought the software. In the United Kingdom, teams have visited software resellers to remind them of the legal consequences of piracy.The new legal measures could take one to two years to wind through courts, depending on how quickly local police cooperate, Le Toquin said. Microsoft investigators purchased most of the fraudulent software through the eBay auction site, which hosts an estimated 50,000 pieces of pirated Microsoft software a year, he said.Some fakes are of such high quality that the compact discs and packaging are sent to a special Microsoft lab in Ireland for confirmation, Le Toquin said. Sellers draw buyers with prices well below market.-Jeremy Kirk, IDG News Service (London Bureau)Related Links:\n\nMicrosoft Office Antipiracy Checks to Become Mandatory\n\nMicrosoft Wins Case Against German Spammer\n\nMicrosoft Faces Class-Action Suit over Antipiracy ToolThis article is posted on our Microsoft Informer page.\u00a0For more news on the Redmond, Wash.-based powerhouse, keep checking in.Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
