The German Patent and Trademark Office (DPMA) has published some interesting statistics on its website: in 2009 69,069 German trade mark applications were filed at the DPMA and 49817 trade mark matured to registration in that year. This is an average of about 200 trade marks per working day. The number of applications has decreased by 6.5 % compared to 2008 (73,903), while the number of trade mark registrations is almost unchanged (2008: 50,259).
Most of the marks (15,450) were filed by applicants from the German state of North Rhine-Westphalia. Even though fewer marks were filed in most German states went compared to 2008, application numbers went up in the states of Brandenburg (1,074), Thuringia (987) and Mecklenburg-Vorpommern (651).
