This is a remake of a video I made a few weeks ago. This time, I was able to go back to the 1840s and show the most-common design patent titles from each era. To make the chart, I used a 14 year rolling average. Thus, for example, the top-10 list shown for 2000 is actually the top-10 based upon the period 1987-2000. The bulk of the data also comes via OCR of images and so there are some artifacts (although I did read-through the first 1,000 design patents). One example that shows up in the data are the “island” patents — that word was somewhat randomly picked-up. Enjoy.
I am cleaning-up the data a bit more and then will make it publicly available.
