He made 47 caps for his Finnish club side FC Honka before agreeing on a move to Allsvenskan outfit Helsingborgs IF on 12 July 2008.

[3] Patronen made his debut with Helsingborg on 15 July 2008 at home against AIK and played for 90 minutes, when his new club won 2–1.

After playing 44 matches and scoring two goals in Allsvenskan with Helsingborg, Patronen was signed on a two-year contract by the Norwegian Tippeligaen side Sogndal ahead of the 2012 season as the replacement for Even Hovland, who had transferred to the reigning Tippeligaen champions Molde.

[4] Patronen soon became an integral part of Sogndal's central defence, and he played 54 matches and scored two goals in Tippeligaen during his two first seasons with the club.

After his two-year contract expired he signed a one-year extension with Sogndal, which kept him to the club to the end of the 2014 season.
