Associated Press is suing a digital news agency, claiming that it uses unlicensed content without paying licence fees. AP, which claims to be the world’s biggest news agency, said on Tuesday it had filed a lawsuit against Meltwater News in a district court in Manhattan. Meltwater News allows its clients to monitor breaking news stories from around the world, including content from AP and other agencies. AP is seeking an injunction and substantial damages from Meltwater News in the copyright infringement action. Tom Curley, outgoing chief executive of AP, accused Meltwater News of a “parasitic” use of content produced by news agencies. AP claimed in its court filing that Meltwater News refuses to pay licence fees for the content it allows users to monitor in the US. The Norway-based firm also has a “vast archive” of AP stories dating back to 2007 which users can store and access despite them not being available online, according to the filing. AP has fought a long-running battle against websites and search engines listing its content. In 2009, the agency went head-to-head with Google over its Google News index, but has since struck licensing deals with the search giant and other internet portals such as Yahoo and AOL.
