We study the uniqueness of meromorphic functions using nonlinear differential polynomials and the weighted value sharing method. Though the main concern of the paper is to improve a recent result of L. Liu [Comput. Math. Appl. 56 (2008), 3236–3245], as a consequence of the main result we also improve and generalize some former results of T. Zhang and W. Lu [Comput. Math. Appl. 55 (2008), 2981–2992], A. Banerjee [Int. J. Pure Appl. Math. 48 (2008), 41–56] and a recent result of the present author [Mat. Vesnik 62 (2010), 169–182].
