John Amster is the CEO of RPX, a San Francisco-based company which helps its customers manage the risk of patent lawsuits.
It's one of two portfolio companies listed on Pao's Kleiner Perkins biography as examples of successful exits.
Pao's complaint does not name RPX, but it mentions a San Francisco-based company which went public in the middle of 2011. That could only be RPX, whose IPO was in May 2011.
According to Pao's complaint, she was primarily responsible for getting Kleiner to invest in the company. But both Nazre and Komisar allegedly stepped in between Pao and RPX.
At one point, Pao said she was courting a CEO to join the board of a company she was backing. (VentureBeat reported that the company in question was RPX.) Nazre allegedly convinced the CEO to join the board of one of his companies instead.
According to Pao's chronology of events, when Kleiner invested in RPX, the firm's partners awarded a seat on the board to Komisar. The complaint says Doerr told Pao that she deserved the seat but Komisar "needed a win."
According to Pao's complaint, several RPX board members wanted Komisar kicked off the board, but Kleiner partners ordered Pao to cut off contact with RPX so Komisar could build a better relationship with the company.
