Intersection of Litigation Finance and Patent Litigation
The following article is part of an ongoing column titled ‘Investor Insights.’ Brought to you by Ed Truant, founder and content manager of Slingshot Capital, ‘Investor Insights’ will provide thoughtful and engaging perspectives on all aspects of investing in litigation finance. EXECUTIVE SUMMARY
INVESTOR INSIGHTS
Investor Insights In my article about “Edge”, I referenced a trend toward specialization, and patent litigation finance is certainly a sub-sector that would qualify as an area of specialization, given the complexity of the cases and the economics at stake. There are a couple of risks inherent in patent litigation that attract my immediate attention as an investor. The first is duration risk, as there are many potential delay tactics, procedural strategies and stumbling blocks that could interfere with the timelines of a patent case. In certain circumstances, the quantum of the issue at risk is so significant that it forces the defendant to push to the bitter end, which results in long timelines and reduces time-based returns. The second issue has to do with early-stage case risk. In the patent space, there are procedural hurdles (IPR, ‘Alice’, Markman, etc.) that could disqualify a case from proceeding, and this adds another element of risk in the early stages of the case. Investors should think about bifurcating (mentally and structurally) this risk into two phases. The first phase encompasses the early stage risk of the case, and investors should be prepared to have a lower win rate during this phase of the case and accept increased loss rates, but also put fewer dollars at risk with the potential for larger rewards. The second phase would be after the hurdles in the first phase have been overcome, whereby investors can take some comfort from the de-risking involved with overcoming these hurdles, but should also expect lower returns with more dollars at risk relative to investors in the first phase. One could argue the patent space has two separate and discrete risk/return profiles, depending on where the case is in its life cycle. Validity IP is presently working on a solution to this problem, which may encourage the litigation finance industry to pursue cases that currently get passed over, due to the presence of phase 1 risks.

- Recent changes in the patent sector have made the case type more attractive to litigation finance
- Litigation finance specialization has started to occur in the intellectual property case market
- Managers focusing on specific case types introduce systematic risk to their portfolios

- Investors should understand how the risk/reward characteristics of a patent case differ from plain vanilla commercial cases
- Case type specialization introduces a systematic risk that cannot benefit from the application of portfolio theory
- Patent cases will occupy a larger proportion of commercial litigation finance portfolios
- Patent litigation is a specialized and complex area of law. Managers investing in the space should have the internal resources to properly underwrite these opportunities
- Patent litigation is expensive, but awards can be gigantic. Through trial, a patent case typically costs $5-10 million. Yet, there is significant pressure on law firms to reduce costs, and legal technology companies are paving the way for more efficient case management. Further, damages available in patent litigation suits can far outweigh the costs. And enhanced damages—discretionary punitive damages that can triple compensatory damages—are more readily accessible after the U.S. Supreme Court’s 2016 decision in Halo Electronics, Inc. v. Pulse Electronics, Inc., which relaxed the standard for finding willful infringement.
- Patent litigation is complicated, but such complication is an advantage for funders that develop expertise. Because patent litigation includes so many traps for the unwary, it is hard to evaluate a patent lawsuit at the outset. Assessing a patent case requires familiarity with the twists and turns of patent litigation, and few funders have the expertise to model the costs, outcomes, expected damages, and timing of a case from start to finish. But that difficulty means that a sophisticated litigation funder who takes the time to understand patent litigation, and carefully considers patent-litigation opportunities, will face fewer competitors and potentially higher rewards for the risk.
- Patent litigation has a high risk of early dismissal, but courts may be more reluctant to dismiss. As discussed in Part II, patent suits have several early choke points. The recent Federal Circuit decision in Berkheimer v. HP Inc. signaled a retreat from early invalidation. Berkheimer recognized that fact issues may preclude courts from resolving early validity That limitation on those challenges provides additional leverage to patent plaintiffs who are prepared to frame factual disputes for maximum effect.
- Patent litigation can take a long time, but key venues are shifting—and speeding up. Relative to other attractive case types, patent disputes can require an extended time horizon, and IPR can freeze litigation in its tracks. Furthermore, the “optimal” strategy for a patent plaintiff might push back recovery by design. For example, a patent plaintiff may wish to litigate against a smaller defendant first, to work through any prior art (earlier uses of the technology that might impact patent validity) and/or claim construction (interpreting the patent claim language) and gain key favorable rulings, then attack the big fish with a cleaner path through litigation. More complex litigation strategies can further challenge the litigation funder. After TC Heartland hobbled EDTX in 2017 and patent litigator Alan Albright took the bench in 2018, the Western District of Texas (WDTX) is now the hottest venue for patent litigation. This year, one in five patent complaints are filed in WDTX, in part because of the speed to resolution plaintiffs can expect there. Judge Albright has resisted litigation stays pending IPR proceedings, he offers to resolve discovery disputes by phone as they happen, and many observers find his scheduling orders “fast-paced,” to say the least. His only completed patent trial (so far) was held less than 13 months after the complaint was filed! Further, because Judge Albright is the only judge in the Waco division, plaintiffs can file there knowing Judge Albright will preside over their case and its schedule. Not only are patent-friendly changes underway at the district courts, there have been favorable trends in another important institution. At the Patent Trial and Appeal Board, where patent defendants commonly seek patent invalidation, Inter Partes Review institution rates have fallen from 87% in FY13 to less than 60% in partial FY20. Institution is the first major hurdle for patent challengers in IPR, and falling institution rates mean fewer patents will be tried (and potentially invalidated) by the PTAB. As a result, IPR is less attractive to patent challengers, and IPR risk to patent holders is declining.
- Patents can be monetized by sale or license, but this option is often unattractive to patent-holders. Unlike commercial litigation claims, which are not (yet?) bought, sold, and licensed with third parties, patents are directly marketable to third parties. A patent holder that wishes to extract value is not forced to hire an army of attorneys to sue an infringer; it can sell or license the patent instead. But many patent holders do not wish to sell or license their patents. Especially in lawsuits against a company's competitor, a dynamic that many funders prefer, the loss of control associated with selling or licensing the patent might be unpalatable to the patent owner. Litigation funding provides patent owners with a way to monetize the patent without losing control of it. And if the patent holder and litigation funder were interested, the funder could purchase a stake in the patent to achieve even better alignment, an option not generally available for other types of litigation.
- Patent litigation had been on the decline, but recent filings suggest a trend reversal. As shown below, patent litigation filings peaked in 2013, remained high through 2015, then fell three straight years through 2018. But recent data suggests patent litigation is reversing course. Interest in patent protection, as measured by the number of patents granted each year, has been trending up since 2009. Patent litigation filings were flat for 2019, and up for the first six months of 2020, despite the COVID-19 crisis. If the second half of 2020 matches the first, annual totals would be up by more than 25%, as projected below. As patent litigation grows, patent opportunities for litigation funders are likely to follow.
