Patent Firm RPX Files for IPO

San Francisco-based RPX, a patent risk management firm with a presence in Seattle, filed an S-1 document with the SEC on Friday that says it intends to sell up to $100 million worth of shares in an initial public offering. Goldman Sachs, Barclays Capital, and others are underwriting the IPO. RPX says it has 70 corporate clients and has spent more than $250 million to acquire intellectual property assets. It reported a $10 million profit for the first nine months of 2010, on revenues of $65.2 million. The company was co-founded in 2008 by former Intellectual Ventures vice presidents John Amster and Geoffrey Barker. Last year, Amster spoke with me about RPX’s approach and recent trends in the patents business.
