This paper reports on two experiments, using polarization techniques with triplet positronium (ps), that have searched for violations of initially the CPT and, most recently, the CP symmetries. Angular correlations between the Ps spin (S) and the momenta of the decay [lambda]-rays ([vert bar]k[sub 1][vert bar] [gt] [vert bar]k[sub 2][vert bar] [gt] [vert bar]k[sub 3][vert bar]) were measured: C[sub n](S [center dot] K[sub 1] [times] k[sub 2]) CPT-test, C[sub CP](S [center dot] k[sub 1])(S [center dot] k[sub 1] [times] k[sub 2]) CP-test.
