ABSTRACT: In this work, we use the Faber polynomial expansion by a new method to find upper bounds for $leftvert b_{n} ightvert $ coefficients for meromorphic bi-univalent functions class $Sigma ^{prime }$ which is defined by subordination. Further, we generalize and improve some of the previously published results.

Key words: Coefficient estimates; Faber polynomial expansion; Meromorphic functions; Subordinate
