You Probably Didn’t Know These Things Were Invented by Women

You Probably Didn’t Know These Things Were, Invented by Women.

In the United States, only about 10 percent of patent holders are women.

According to 24/7 Tempo, this disparity is partly due to the fact that women applying for patents alone are more likely to be rejected by the U.S. Patent and Trademark Office.

In addition, patents sought by women are more likely to require revisions that lower the scope of the patent, subsequently weakening it.
