Levi's patented

In 1873, Jacob W Davis of Reno, Nevada, received a U.S. patent (No.139,121) on a rivet process for strengthening the pocket openings of canvas pants. He assigned the patent to himself and Levi Strauss, as his business partner. Jacob Davis was in charge of manufacturing when Levi Strauss & Co. opened its two San Francisco factories. Sometime during 1873, the first riveted clothing was made and sold. (The exact date is unknown; the company's historic records were lost in the 1906 San Francisco earthquake and fire.) For nearly 20 years, Levi Strauss & Co. was the only company making riveted clothing, until the patent expired around 1891. Thereafter, dozens of garment manufacturers began to imitate the original riveted clothing.
