Patent Holder of Piggly Wiggly Self-Service Method Sued Hoggly Woggly for Infringement
(p. A11) A typical U.S. supermarket carries 42,000 items: Grab a cart, stroll the aisles and help yourself to an extravagant assortment of goods. Today it's hard to imagine buying groceries any other way. But self-service was a game-changer when Clarence Saunders opened the first Piggly Wiggly in Memphis, Tenn., 100 years ago this month.
Before then a shopper would hand his grocery list to a clerk, who would fetch the merchandise while the customer lingered up front. That might sound appealing in this era of big-box stores with no help in sight, but at busy times the wait could stretch uncomfortably long.
Saunders, a school dropout who worked as a flour and grain salesman, had observed firsthand the inefficiencies of the rural grocers he supplied. Many of these stores, he became convinced, failed for two reasons: credit losses from customers' charge accounts (which were then customary), and labor costs from clerks and delivery boys.
. . .
Eager to protect his invention, Saunders applied for multiple patents. His first, for a "Self Serving Store," was granted in 1917. It wasn't long, though, before imitators like Handy Andy and Helpy Selfy made their debut. Saunders successfully sued an especially brash copycat, Hoggly Woggly, for infringement.
. . .
Saunders didn't integrate circuits or sequence the human genome. An observer once noted that coming up with a self-service grocery was "as simple as looking out the window or scratching your ear." Still, it was Saunders who gambled on the unconventional approach, doggedly spread self-service across the nation and shaped the grocery industry we know today.
