A $2 billion patent suit against Intel Corp. that was shut down this week by a jury in Delaware was backed by a third-party litigation funder. And all signs point to Gerchen Keller Capital, which was acquired last year by publicly-listed Burford Capital.

The case offers a glimpse of the kinds of legal matters that litigation funders are investing in, and how they can sometimes go south. Most deals are kept hush-hush by non-disclosure agreements between the parties, although the existence of funding is sometimes disclosed for regulatory reasons or when a firm or party feels it serves their interest.
