Most Common Design Patents 1842-2021
SEPTEMBER 19, 2021
This time, I was able to go back to the 1840s and show the most-common design patent titles from each era. 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. Patentby Dennis Crouch. link].
