"He matches up very well with us. He spent 30 years at IBM and has a lot of experience in antitrust and patents, a very broad background." Rosenberg replaces Lou Lupin, who resigned in mid-August after Qualcomm endured a string of legal setbacks. Carol Lam, a former U.S. attorney in San Diego who joined Qualcomm last year as a vice president, had been interim general counsel while the company looked for Lupin's replacement. Advertisement During Lupin's tenure, Qualcomm was found by a federal judge to have knowingly failed to turn over thousands of relevant documents in a patent trial against Broadcom. Judge Rudi Brewster said Qualcomm not only concealed documents but also intentionally deceived a standards body. Because of "exceptional" misconduct on Qualcomm's part, Brewster ordered the company to pay Broadcom's legal expenses, which could run as high as $10 million.
