Recently Ozbal and Firat [22] introduced the notion of symmetric bi-derivation of a lattice. They give illustrative examples and they also characterized the distributive lattice by symmetric bi-derivation. In this paper, we define the isotone symmetric bi-derivation and obtain some interesting results about isotoneness. We also provide the relations between distributive, modular, and isotone lattices through symmetric bi-derivation.
