By aggregating the data we get the table I'm posting here below, containing 174 application authorities (data from 10/2009 patstat version). When considering instead only those who have more than 1000 applications, the figure decreases to 78 patent offices.
Some will notice that among the 174 the achronim WO (WIPO/PCT patent office) does not appear. This is because WO pubblications always result from an application to a local patent office (domestic or EP) where the PCT procedure is applied. The extent of this practice will be subject of one further post.
