Trevor Cook of Bird & Bird points out that the EMW Picton Howell litigation stats we quoted in our recent post tell an unrepresentative part of the whole story. The Lord Chancellor's Dept/DCA/Ministry of Justice statistics on IP litigation (which we summarise in tabular form) show that 2006 was a terrible baseline year to choose - the increases in 2007 and 2008 merely restore the position earlier in the decade. These and many other fascinating things are to be found in Trevor's very readable "Users' Guide to Patents". Thanks, Trevor, for putting it in perspective. Are these variations statistically significant at all, or just noise? Comments welcome as always.
