In December 1873 Major Walter Clopton Wingfield designed an hourglass-shaped tennis court in order to obtain a patent on his court (as the rectangular court was already in use and was unpatentable). A temporary patent on this hourglass-shaped court was granted to him in February, 1874, which he never renewed when it expired in 1877. It is commonly believed, mistakenly, that Wingfield obtained a patent on the game he devised to be played on that type of court, but in fact Wingfield never applied for nor received a patent on his game, although he did obtain a copyright — but not a patent — on his rules for playing it. And, after a running series of articles and letters in the British sporting magazine The Field, and a meeting at London's Marylebone Cricket Club, the official rules of lawn tennis were promulgated by that Club in 1875, which preserved none of the aspects of the variations that Wingfield had dreamed up and named Sphaeristikè (, that is, "sphere-istic", an ancient Greek adjective meaning "of or pertaining to use of a ball, globe or sphere"), which was soon corrupted to "sticky". Wingfield claimed that he had invented his version of the game for the amusement of his guests at a weekend garden party on his estate of Nantclwyd, in Llanelidan, Wales in 1874, but research has demonstrated that even his game was not likely played during that country weekend in Wales.The History of Tennis – Mary Bellis He had likely based his game on both the evolving sport of outdoor tennis and on real tennis. Much of modern tennis terminology also derives from this period, for Wingfield and others borrowed both the name and much of the French vocabulary of real tennis, and applied them to their variations of real tennis. In the scholarly work Tennis: A Cultural History, Heiner Gillmeister reveals that on December 8, 1874, Wingfield had written to Harry Gem, commenting that he had been experimenting with his version of lawn tennis for a year and a half.Leamington Tennis Court Club Gem himself had largely credited Perera with the invention of the game.
