Abstract: Let $D$ be a skew field with infinite center $K$ such that $[D:K]=\infty $, and let $H$ be a non-central subnormal subgroup of the multiplicative group $D^*=D\backslash \{0\}$ of $D$. Then there are no non-trivial generalized rational identities of $H$. This generalizes a theorem proved by Makar-Limanov.
