We are working on our 4th patent filing. Although our patent attorney takes care of big part of the very interesting but time consuming work, there is some stuff we need to do ourselves. Last week we had to go to the "Swiss Federal Institute of Intellectual Property” to do some worldwide research on existing patents. These are intense hours and need lots of attention, fast reading and some strong coffee. We went through almost 200 patents in a day. The results were exactly what we were hoping for. Thanks Joachim!
