Microsoft has taken an extra step in its fight against software piracy by filing lawsuits against 52 alleged resellers of counterfeit software, and has referred 22 piracy cases to law enforcement agencies in 20 different countries. According to the company, 15 of the lawsuits involve software which has been traced back to what is believed to be the largest ever counterfeit software syndicate, which was broken up by Microsoft and law enforcement officials from the US and China earlier this year. Microsoft is also working with eBay to produce the "Microsoft Buying Guide" to inform consumers of how to safely buy software from sites such as eBay.
