In 2005, oppositions were filed against 5.4% of granted patents, compared with a rate of 5.3% in 2004. Fewer oppositions were filed in 2005 (2,960) than in 2004 (3,100), reflecting a slight fall in the number of patents granted over the same period, see James Wilding and Andy Bridle in Managing Intellectual Property
