For fifty years between 1940 and 1990, The St. Louis Post Dispatch had a section in its comics pages titled Our Own Oddities, featuring unusual things from around the St. Louis metropolitan area. There are a number of patent “oddities,” and while they may not be as astounding as a Nixon-shaped potato they are nonetheless cataloged below.
The First Patent
The first patent, as most patent attorneys know, was issued to Samuel Hopkins on July 31, 1790, on a method of making potash and pearlash. However U.S. Patent No. 1 issued to J. Ruggles on July 13, 1836, when it finally occurred to someone in the Patent Office to start numbering these things. Approximated 10,000 unnumbered patents, often call the X-series of patents were issued prior to U.S. Patent No. 1.

The first patent to issue to a female inventors is believed to be one of the aforementioned X-series patents, No. 1041X on Weaving Straw with Silk Thread, issued to Mary Kies on May 5, 1809.
First Patent to an African-American Inventor
