In 1900, German chemist Felix Hoffmann was issued a U.S. patent for “Acetyl Salicylic Acid” (No. 644,077). It was assigned to the Farben-Fabriken of Elberfeld Company, of New York. Hoffmann had discovered the chemical compound on 10 Aug 1897 while a researcher at the Bayer company. It was marketed as Apirin, the familiar pain reliever, which at the time was a trademarked name. It was first sold in Germany in powder form, from 1 May 1899, and later in the more convenient tablet form, from 1 Jan 1915.
