Johnny Briscoe filed suit earlier this month in federal court seeking unspecified damages.
Briscoe was freed in July 2006 after DNA cleared him of a 1982 rape in the St. Louis County community of Maryland Heights.
Briscoe alleges he was denied the right to a fair trial. He also claims that authorities used improper methods of identification.
Missouri law lets Briscoe receive up to $36,500 from the state for each year he was wrongly incarcerated, if he agrees not to file suit.
Briscoe's attorney, Burt Newman, tells St. Louis radio station KMOX the compensation is not enough.
