Football: German Patent Office Website

A post from my other blog which may interest some of your chaps is on the German patent and trade mark office's contribution to the world cup celebrations "Fußball und Technik" ("Football and Technology"). It covers virtually everything one could ever wish to know about football and intellectual property from patent specifications for footballs to the prior art of stadium technology. The site is in German but many of the specifications are from the UK and other English speaking countries and navigation is pretty obvious.
