When walking in the countryside, we discovered an old and rusted farming machine for the harvest of the hay. The machine by itself looks very strange but I was surprised by the metal label on top : "patent melichar-hajek". Yes, a part of the machine was patented (around 1944, thanks Google for the new patent search). I took a picture of it for the history… I'm still convinced that the patent system is an outdated system for today's world.
