When you pick up a pair of Levi’s® blue jeans or a vintage Levi’s® jacket, one of the first things you’ll notice are those little metal rivets. They’re not just there for looks — they reinforce the seams, extending the durability and lifecycle of the clothing.
They’re also what make blue jeans blue jeans, from a patent sense.
The Birth of the Blue Jean
The invention of riveted denim by Jacob Davis and Levi Strauss & Co. marked a turning point in the history of workwear and fashion. Patented on May 20, 1873, the innovation — which introduced metal rivets to reinforce common points of stress on pants, particularly at pocket openings and seams — solved the long-standing issue of garments tearing under strain and signified a major milestone for both LS&Co. and society at large.
The result? A durable and practical garment that quickly gained popularity among miners, cowboys, farmers and other laborers — and the origin of the modern blue jean.
The 1875 Patent Reissue: Expanding the Vision
While the initial U.S. Patent No. 139,121 focused on reinforcing pocket openings with rivets to prevent ripping, Jacob Davis and LS&Co. recognized the potential for broader applications. Less than two years later, on March 16, 1875, they secured a reissue of their patent (RE 6,335), expanding the scope beyond “pantaloons” to include “other garments” with riveted pocket openings or seams. By broadening their claim, they ensured the versatility of their invention across different types of apparel, solidifying its relevance in various industries.
The reissued patent also emphasized the use of rivets to strengthen seams under constant strain. This foresight not only protected their intellectual property but also paved the way for LS&Co. to innovate further in garment manufacturing, like introducing riveted coats, blouses (jackets) and jumpers. The reissue underscored our commitment to durability and adaptability — qualities that remain central to Levi’s® products today.
A Lasting Legacy
Jacob’s invention and its subsequent evolution through the 1875 reissue reflect a profound understanding of both practical needs and market potential. Today, 150 years later, riveted denim — the modern blue jean — continues to symbolize resilience and style, worn by people worldwide across generations and professions. The ingenuity reminds us that even the simplest ideas, like reinforcing a seam, can leave an indelible mark on history.
