Levi Strauss & Company
In 1873, Levi Strauss & Company began using the pocket stitch design. Levi Strauss and Nevada tailor David Jacobs co-patented the process of putting rivets in pants for strength. On May 20, 1873, they received U.S.Patent No.139,121. This date is now considered the official birthday of "blue jeans."
The two-horse brand design was first used in 1886. The red tab attached to the left rear pocket was created in 1936 as a means of identifying Levi’s jeans at a distance. All are registered trademarks that are still in use.
