Inside the data on women inventors

The United States Patent and Trademark Office (U.S.P.T.O.) recently released a report on women inventors on U.S. patents. The key findings in the report include:

  • The number of patents with at least one woman inventor increased from about 7 percent in the 1980s to 21 percent by 2016;
  • Despite this increase, the percentage of all patent inventors that are women, or the annual “women inventor rate,” reached only 12 percent in 2016;
  • Notable differences in the number of male and female patent inventors persist despite greater female participation in science and engineering occupations and entrepreneurship;
  • Women inventor rates are higher in technology-intensive states, but also in states where more women participate in the overall workforce;
  • Women inventors are increasingly concentrated in specific technologies and types of patenting organizations, suggesting that women are specializing where female predecessors have patented rather than entering into male-dominated fields or firms;
  • Women are increasingly likely to patent on large, gender-mixed inventor teams, highlighting the growing importance of understanding the relationship between gender and innovative collaboration;

Of the 20 patents listed below, only one lists a female inventor.

The U.S. Patent and Trademark Office issued the following patents to South Dakota inventors in January 2019.
