Interdigital — Key Risks
Royalty Rates May Be Set by Courts or Arbitrators at Unfavorable Levels
Because many licensees refuse to negotiate voluntarily, InterDigital often ends up in legal proceedings where a third party — a judge, arbitrator, or regulator — sets the royalty rate instead of the two sides agreeing. Chinese courts have already claimed the right to set worldwide royalty rates for standard-essential patents (SEPs — patents that must be used to comply with industry standards like 5G), and did exactly that for Nokia's cellular patents in December 2023. InterDigital faces similar proceedings with OPPO in China and royalty-setting cases in the UK from Amazon and Tesla. A single unfavorable ruling could devalue InterDigital's entire patent portfolio and drag down rates with all future licensees.
Heavy Revenue Concentration in a Few Licensees Creates Outsized Risk
In 2025, Samsung, Apple, and vivo each individually accounted for 10% or more of InterDigital's total revenue. Separately, Samsung, Apple, and Xiaomi together controlled over 50% of worldwide smartphone shipments. If any one major licensee refuses to renew, delays payments, or wins a favorable arbitration ruling, it can meaningfully damage the company's revenue in a single quarter.
The Video and Cloud Services Licensing Push Is Unproven
InterDigital is betting a meaningful part of its growth on licensing patents to video streaming and cloud service providers — a market far less developed than its traditional device licensing business. The company has not yet signed its first video services license. Providers may argue there are no comparable deals to benchmark against, stall negotiations, or simply adopt competing technologies that InterDigital's patents don't cover.
US-China Trade Tensions Directly Threaten a Core Revenue Base
Chinese companies represent a substantial portion of InterDigital's licensees. The US government's 2025 tariff escalation increased trade tensions, and any retaliatory measures from China could make it harder for InterDigital to negotiate or renew license agreements with Chinese manufacturers — a group that is central to its business. The company acknowledges China is a key market and that the ultimate impact of ongoing tensions remains uncertain.
Future Patent Royalties Face Structural Downward Pressure
Licensees are increasingly arguing that royalties should be calculated on the "smallest salable patent practicing unit" — the individual component that uses a patent — rather than the full device selling price. At the same time, device prices in the handset market are under downward pressure, and since some of InterDigital's royalties are tied to device pricing, this squeezes revenue from two directions simultaneously.
Regulatory and Legislative Changes Could Weaken Patent Enforcement
Laws governing how SEP holders can enforce their patents are actively being debated in the US, EU, and China. Proposals in recent years have targeted the remedies available to patent holders — including restricting injunctive relief (court orders forcing infringers to stop). While the EU's proposed SEP regulation was withdrawn in 2025, discussions are ongoing. Any reforms that reduce available legal tools would make it harder for InterDigital to pressure holdouts into licensing deals.
Tax Benefits That Boost Profitability Are at Risk
A significant share of InterDigital's US income qualifies for foreign-derived intangible income (FDII) treatment, currently taxed at a preferential 13% rate — rising to 14% in 2026. In France, the company benefits from research tax credits (Crédit Impôt Recherche), which the French government is now partially challenging. The newly enacted US "One Big Beautiful Bill Act" introduces additional corporate tax changes, and the OECD's global 15% minimum tax applies to InterDigital starting in 2026. Together, these shifts could meaningfully increase the company's effective tax rate.
