Some new solutions for the equation of motion in $ϕ^4$-theory with damping are constructed. These solutions describe the field configurations corresponding to the coupled states of three kinks and/or antikinks. To obtain them a new direct method for nonlinear partial differential equations which generalises the Hirota method for the a degeneracy case is applied.
