Alcatel-Lucent S.A. (French pronunciation: [alkatɛl lysɛnt]) was a French global telecommunications equipment company, headquartered in Boulogne-Billancourt, France. It was formed in 2006 by the merger of France-based Alcatel and U.S.-based Lucent, the latter being the successor of AT&T's Western Electric.
The company focused on fixed, mobile and converged networking hardware, IP technologies, software and services, with operations in more than 130 countries. It had been named Industry Group Leader for Technology Hardware & Equipment sector in the 2014 Dow Jones Sustainability Indices review and listed in the 2014 Thomson Reuters Top 100 Global Innovators for the 4th consecutive year. Alcatel-Lucent also owned Bell Laboratories, one of the largest research and development facilities in the communications industry, whose employees have been awarded eight Nobel Prizes and the company holds in excess of 29,000 patents.
On 3 November 2016, Nokia completed the acquisition of the company and it was merged into their Nokia Networks division. Bell Labs was still maintained as an independent subsidiary of Nokia. The Alcatel-Lucent brand has been replaced by Nokia, but it still survives under Alcatel-Lucent Enterprise (ALE), the enterprise division of Alcatel-Lucent that was sold to China Huaxin in 2014.
