Earlier this year, RPX flagged an SEC filing by NPE Quest Patent Research Corporation (QPRC) that revealed a financial stake held by Intellectual Ventures LLC (IV) in QPRC’s litigation. A disclosure filed with the court this week in an IPValuation Partners LLC (d/b/a IPVal) case suggests that IV—which has assigned at least 80 US assets to IPVal to date—may have an interest in the success of additional NPE campaigns.
