The 2021 Litigation Finance Market Report released this week by Westfleet Advisors reports that a pool of 47 litigation funders active in the US have combined assets under management of $12.4B. Of course, not all that capital is funding patent litigation; however, according to Westfleet’s study, “patent litigation attracted a significantly higher percentage of new commitments in 2021, comprising 29% of all capital commitments”. In an earlier version of its annual report, published in January of this year, the firm proclaimed that in the context of commercial litigation finance, “patent litigation is king”. Indeed, a steady stream of new third-party backed campaigns suggests continued investor interest in patent litigation. Here, RPX takes a look at three of the litigation funders tied by public records to new patent campaigns initiated during the first quarter of 2022.
