What is the origin of this conservative figure? I hunted down the full CIBER documents, found the references section, and followed the web link, which led to a 2004 press release from a private legal firm called Rouse who specialise in intellectual property law. This press release was not about the ?10bn figure. It was, in fact, a one page document, which simply welcomed the government setting up an intellectual property theft strategy. In a short section headed ?background?, among five other points, it says: ?Rights owners have estimated that last year alone counterfeiting and piracy cost the UK economy ?10 billion and 4,000 jobs.? An industry estimate, as an aside, in a press release. Genius.
