Pattern is said to have originated from the Roman estate of Paternius and was first mentioned in documents in 893. In 1166, a Simon von Pattern and his sons were mentioned by the Archbishop of Cologne as owners of an estate near Euskirchen. This knightly family, which probably died out early, had its seat in Pattern in the late Middle Ages. In 1376, Hermann von Lievendahl was mentioned with the nickname "von Pattern", and at the beginning of the 16th century, through the marriage of a Maria von Lievendahl to Dietrich von Ahr, part of Pattern fell to the family later known as the "House of Ahr". From 1794 to 1814, Pattern belonged to the French Département de la Roer, and from 1815 to the Jülich district in Prussia. On January 1, 1972, the community of Pattern near Aldenhoven became part of Aldenhoven in the newly formed Düren district. It was excavated in the 1980s because of open-cast lignite mining. Other places in the area around Pattern that were excavated were Erberich and Lohn.
From 1961 to 1971, Pattern had the postcode 5171 Pattern near Aldenhoven (via Jülich) and then 5173 Aldenhoven. Pattern was no longer included in the new five-digit postcodes. The additional name of Aldenhoven was necessary because of the town of the same name, 5171 Pattern near Mersch (via Jülich).
