There are things in this world which are known more or less universally. This is basically a good thing since it provides common grounds. Especially if the object of common knowledge is a young woman with a friendly smile. Own photo taken from the back of Mona's exhibition room with a 300mm f2.8 - over the heads of dozens of spectators, queuing with their phones at the ready. The bluish clouds in the lower parts are reflections of this crowd in the bulletproof glass in front of the painting. Let me be clear at the outset: I am in no...

I found an old blog article in an archive folder of my hard drive. Although I wrote it in August 2011, it seems still valid to me.

Chances are good that you find beside the producer's name and model a list of say 6 to 10 US patents listed. Electronic pocket calculators are in widespread use for more than 50 years. The typical function didn't change much over this time. So, what could be patented in this...
