These days in Silicon Valley, a law firm scoring several million bucks from a client investment is hardly news. But more than $20 million? For one lawyer? Now we’re talking real money!

The lucky winner is Craig Johnson, founder of Menlo Park’s Venture Law Group and one of the Silicon Valley’s most entrepreneurial lawyers. Johnson’s windfall comes from his stake in SnapTrack, Inc., a privately held company that was bought by Qualcomm Incorporated in March for $1 billion. According to securities filings made March 21 when Johnson’s Qualcomm stock was registered for sale, he received roughly 146,000 Qualcomm shares for his Snaptrack equity. At that time, the stock was valued at nearly $22 million, though as of April 14 it was worth just $15.3 million.
