Tech giant Qualcomm has announced the resignation of its general counsel Lou Lupin after 12 years in the job.

Lupin, who joined Qualcomm in 1995 and became general counsel at in 2000, resigned on Monday (13 August).

His position will been filled in the interim by Qualcomm legal counsel Carol Lam while the company searches for a replacement. Lam joined the company in February and previously served as the US attorney for the Southern District of California. She was one of eight federal prosecutors controversially fired by the Bush administration earlier this year.

Qualcomm chief executive Paul Jacobs said: "We are appreciative of Lou's many valuable contributions to the company. He has played a major role in the formation of Qualcomm's successful technology licensing program and negotiation of key licensing agreements."

Qualcomm is the world's second-largest chip manufacturer for mobile phones. Last week the US Government upheld a ban, imposed in June after a patent dispute with rival chip-manufacturer Broadcom, on imports of mobile phones containing Qualcomm chips.
