Patek Coen (SEY 2786 - 2867) was a navjumper most notable for his discovery of the Kellog system in 2811.

Born on Kampos (Ellis IV), Coen began his career as a pilot for a private ferry service from Kampos to neighboring planets Green (Ellis III) and Noble (Ellis V). He became interested in navjumping after reading a biography on Antoine Lebec, and took on private training courses in navigation and detection in his spare time. It was his goal to eventually live in a system he discovered himself.

After nearly a decade of searching, Coen found a jump point to Kellog, but was disappointed when the existence of the Orm civilization on Kellog II came to light and the system was placed under the Fair Chance Act (FCA), meaning that he could not reside there. He retired from navjumping in 2839 when his autobiography A Refuted Dream became an unexpected bestseller.
