  We review recent theoretical results from our systematic study of
QCD-instanton contributions to eP processes, involving a hard momentum scale Q.
The main issues are: the absence of IR divergencies due to a dynamical
suppression of instantons with large size rho > 1/Q, the reliable calculability
of instanton-induced amplitudes and our inclusive framework to systematically
calculate properties of the instanton-induced multi-parton final state.
