Narrative:

Cpr X climbing wbound to FL210 infringed on ZAU airspace at FL190 without proper coordination. Controller at ZAU reported incident to supervisor. I was informed 4 days later. I had judged the climb rate of cpr X to be sufficient enough to clear the airspace which was FL190 and below. I became involved with a confusing situation with inbound aircraft south of cpr X, that required coordination and my immediate attention. Cpr X did not climb as well as I expected and when I realized that the aircraft needed coordination it was too late to call. The aircraft was already out of the involved airspace.
