Cleary Gottlieb Steen & Hamilton is once again taking the lead for Google as the Internet search giant unloads subsidiary Motorola’s set-top box business to the telecommunications equipment company the Arris Group for $2.35 billion.

The deal, the terms of which call for Google to retain a 15.7 percent stake in the unit, comes a little more than a year after Cleary advised Google on its $12.5 billion acquisition of Motorola. Regulators in the United States and Europe approved that deal earlier this year.
