  We investigate the prospect of discovering the Inert Doublet Model scalars at
CLIC. As signal processes, we consider the pair-production of inert scalars,
namely e+e- -> H+H- and e+e- -> AH, followed by decays of charged scalars H+
and neutral scalars A into leptonic final states and missing transverse energy.
We focus on signal signatures with two muons or an electron and a muon pair in
the final state. A number of selected benchmark scenarios that cover the range
of possible collider signatures of the IDM are considered. For the suppression
of SM background with the same visible signature, multivariate analysis methods
are employed. For several benchmark points discovery is already possible at
low-energy stage of CLIC. Prospects of investigating scenarios that are only
accessible at higher collider energies are also discussed.
