Tipp-Ex is a brand of correction fluid and other related products that is popular throughout Europe. It was also the name of the German company (Tipp-Ex GmbH & Co. KG) that produced the products in the Tipp-Ex line. While Tipp-Ex is a trademark name for correction products, in some countries it has become a genericised trademark: to tippex or to tippex out means to erase, either generally or with correction fluid. History Tipp-Ex correction paper was invented by Wolfgang Dabisch from Eltville, West Germany, who filed a patent in 1958 on Colored film for the correction of typing errors (German: Tippfehler). He subsequently founded a company of the same name. Shortly after that a Tipp-Ex Sales & Distribution company (Tipp-Ex Vertrieb GmbH & Co. KG) was founded in Frankfurt by Otto Carls. This company still exists under the name of Tipp-Ex GmbH & Co. KG close to Frankfurt. Tipp-Ex became a registered trademark with the German patent office in 1987. Earlier, in 1951, Bette Nesmith Graham invented the first correction fluid in her kitchen and began marketing the product in 1956 as Mistake Out. Tipp-Ex GmbH only started to produce white correction fluid in 1965 under the brand Tipp-Ex, but also as C-fluid. As a result of the invention of Tipp-Ex, it became possible to erase a typographical error made on a typewriter. The typewriter would be backspaced to the letter that was to be changed, the correction paper would be placed behind the ribbon, and the mistyped letter would be re-typed. The system only worked if the typewriter repositioned the re-typed letter in exactly the same place as originally typed, which could be problematic if returning to a previous line. Demand for this correction paper grew very quickly and brought interest from German and international distributors. In 1992 Tipp-Ex introduced its first correction tape, followed in 1995 by the successful Pocket Mouse which worked as a best seller. In 1998, the correction pen was launched. The range was extended to erasers, and in 2000, the new foam applicator was adapted to all the correction fluid bottles. In 1997, Société Bic acquired Tipp-Ex. Usage Tipp-Ex correction fluid is a white liquid. It is used for painting over mistakes in a piece of writing.
