Patents have played a significant role in Black history, as they have often been used by African Americans to protect their inventions and innovations. One notable figure in this regard is Elijah McCoy, a Canadian-born African American inventor who received over 50 patents in his lifetime. McCoy is best known for his invention of an automatic lubrication system for steam engines, which revolutionized the industrial sector by allowing machines to operate more efficiently.

Another important figure in the history of patents is Sarah E. Goode, who became the first African American woman to receive a patent in 1885 for her folding cabinet bed. This invention was a space-saving solution for small urban apartments and was highly successful.

Throughout history, many other African Americans have obtained patents for their inventions, contributing to advancements in various fields such as technology, medicine, agriculture, and more. Despite facing significant barriers and discrimination, these inventors persisted in pursuing their ideas and securing patents to protect their intellectual property.

Overall, the history of patents in Black history showcases the ingenuity, creativity, and determination of African American inventors who have made significant contributions to innovation and technology.
