Interdigital — Business Overview

What does InterDigital do?

InterDigital is a pure research and development company that invents foundational wireless and video technologies, patents them, and then licenses those patents to the companies that build the products and services relying on those inventions. It does not manufacture anything. Instead, its roughly 460 employees spend their time developing technology that ends up embedded in smartphones, televisions, Wi-Fi routers, connected cars, streaming services, and more. As of December 31, 2025, InterDigital held more than 38,000 patents and patent applications worldwide, covering cellular standards (2G through 5G and upcoming 6G), Wi-Fi (802.11), and video coding formats (H.264, HEVC/H.265, VVC/H.266, and others). Total revenue in 2025 was $834 million, down from $869 million in 2024.

The company's research spans three interconnected technology pillars: wireless, video, and artificial intelligence. On the wireless side, InterDigital has contributed to every major cellular generation and continues working on 5G Advanced and 6G. On the video side, it acquired Technicolor's research and patent licensing unit, giving it a deep portfolio in the codecs (compression formats) that underpin virtually all modern video streaming. AI sits at the intersection of both, applied to problems like more efficient video compression and smarter wireless networks.

How does InterDigital make money?

The overwhelming majority of InterDigital's revenue comes from licensing fees paid by companies whose products or services use InterDigital's patented technologies. Most agreements are fixed-fee multi-year deals, meaning licensees pay a set amount over the contract term regardless of exact unit volumes. A smaller portion of agreements are variable (royalty per unit sold) or hybrid. New agreements often include a catch-up payment covering past unlicensed sales — for example, the 2025 Samsung arbitration award included $118 million of catch-up revenue in addition to the ongoing ~$131 million per year going forward, a 67% increase from the prior agreement. Three customers each exceeded 10% of 2025 revenue: Samsung, Apple, and vivo.

InterDigital also licenses through pooling platforms to reach markets like IoT and automotive more efficiently. The Avanci platform bundles cellular standards-essential patents from multiple holders into a single flat-rate license for connected-device makers. Avanci covers automotive (participants include BMW, Audi, Ford, Toyota, BYD, and Volvo), representing over 80% of annual connected car shipments. The Madison Arrangement is a joint program with Sony combining both companies' TV and monitor patents into one license offering, with InterDigital acting as exclusive licensing agent.

A newer and still-developing revenue stream targets video streaming services directly. InterDigital argues that platforms like Disney+ and Amazon Prime Video use patented video coding technology and therefore owe license fees. In 2025, InterDigital filed patent infringement actions against Disney and Amazon, and courts in Brazil and Germany issued injunctions against Disney streaming services. This service-based licensing program is early-stage but targets a market projected to grow from $475 billion in annual revenue in 2025 to $675 billion by 2029.

What market does InterDigital operate in?

InterDigital's primary served markets are smartphones, consumer electronics, IoT/automotive, and video streaming services — all growing end markets that depend on wireless connectivity and video. The smartphone market shipped approximately 1.2 billion units in 2025 and returned to growth driven by 5G adoption and emerging-market upgrades from feature phones. Televisions add another 200 million-plus units annually. Global cellular IoT device shipments are expected to grow from roughly 550 million units in 2025 to 800 million by 2029. Connected passenger vehicle shipments stood at about 65 million in 2025 and are expected to grow significantly.

The underlying secular trend strongly favors companies holding essential wireless and video patents. Each new generation of wireless standards (5G, eventually 6G) and video codecs (VVC replacing HEVC) creates a new licensing cycle, because device makers need licenses to the new standard's essential patents. More devices going online — wearables, smart-home products, autonomous vehicles — expands the potential licensee base. The rapid growth of video streaming adds an entirely new category of prospective licensees beyond hardware makers.

Who are InterDigital's main competitors?

InterDigital competes not in a traditional product market but in the arena of standards-setting and patent licensing, where its rivals are other holders of standards-essential patents (SEPs). Companies like Qualcomm, Ericsson, Nokia, and Samsung itself hold large SEP portfolios and also seek royalties on wireless-enabled devices. The practical competitive dynamic is not "winner takes all" — a single device can require licenses from many patent holders simultaneously — but licensees often push back on the total royalty burden, arguing there is a ceiling on what any one holder can charge. This is the FRAND (fair, reasonable, and non-discriminatory) framework: companies that contribute patents to a standard commit to licensing on FRAND terms, which courts and arbitrators sometimes have to define.

InterDigital's claimed advantages rest on the quality and breadth of its portfolio and its pure-play R&D focus. The company describes itself as one of the largest pure R&D and licensing firms in the world, spending $211 million on research in 2025. Unlike a Qualcomm or Nokia, which also sell chips or network equipment, InterDigital has no product business to protect — its only product is intellectual property. It has licensed approximately 85% of the global smartphone market by shipments and holds licenses with eight of the ten largest smartphone vendors.

Where does InterDigital operate?

InterDigital is headquartered in Wilmington, Delaware, with research operations spread across North America and Europe. Primary R&D sites include Conshohocken, Pennsylvania; New York; Los Altos, California; Montreal; London; and Rennes, France. Smaller offices exist in Belgium, Finland, Canada, and China. Of its approximately 460 employees, roughly 240 (just over half) are based outside the United States. French employees are subject to collective bargaining agreements.

Revenue, however, is global and heavily weighted toward Asian device manufacturers. Samsung, Apple, vivo, Honor, OPPO, Xiaomi, and LG are all major licensees. Chinese smartphone vendors represent a meaningful and growing portion of the licensed base — vivo and Honor both signed new agreements in 2025. This means a large share of InterDigital's royalty income depends on licensing negotiations with companies headquartered in South Korea, China, and the United States. The filing notes ongoing legal and licensing activity in multiple international jurisdictions, including arbitration before the International Chamber of Commerce and court proceedings in Brazil, Germany, and elsewhere, reflecting the global nature of both its licensees and its enforcement efforts.
