InterDigital, Inc.: what insiders have been doing
Headquartered in Wilmington, United States, InterDigital, Inc. belongs to the Technology sector and traces its origins to 1972. Filings by its managers are published through SEC (Form 4). Between 18 October 2025 and 18 October 2026, 20 insiders published 112 filings.
The flow runs one way only: 31 sales worth €9.8M, from 9 insiders, and no purchase. The totals do not cover 2 filings with an undisclosed amount. Biggest ticket of the year: €848k, sold by Chen Lawrence Liren and made public on 7 January 2026 (0.010% of market cap).
For context, the typical company on the same exchange (median of 5,810 companies) published 19 filings over the same period, against 112 filings here. The full history, which starts in 2016, counts 1 purchase against 105 sales. On the fundamentals side, the SEC filing (10-K) for the period ending 31 December 2025 lists revenue at 834.0 m USD and net income at 406.6 m USD; the dividend was 2.60 USD per share.
Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. Section 16 rules allow two business days to file each Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning.
In the same sector, recent insider purchases at Core Scientific, Inc./tx and Gitlab Inc. also feature in our signals. These figures are compiled from regulatory filings published by SEC (Form 4). They describe what insiders did and are not a recommendation.

About InterDigital, Inc.
InterDigital, Inc. (ticker IDCC) is a U.S.-based technology research and development company listed on the NASDAQ market in the United States. Headquartered in Wilmington, Delaware, the company focuses on wireless, video, and artificial intelligence technologies, with a business model built around innovation, standards participation, and intellectual property monetization. Its corporate roots date back to 1972, giving it more than five decades of history in communications technology and standards-driven development. ([sec.gov](https://www.sec.gov/Archives/edgar/data/1405495/000140549526000011/idcc-20251231.htm?utm_source=openai))
InterDigital’s core model is centered on applied research and patent licensing rather than hardware manufacturing. The company develops technologies for mobile communications, Wi‑Fi, digital video, and AI-enabled communications solutions. It works closely with global standards organizations to help shape successive generations of connectivity, from 5G toward 6G, as well as next-generation video codecs. This standards-led approach supports the monetization of a portfolio of standards-essential patents and underpins commercial relationships with smartphone makers, network equipment vendors, consumer electronics companies, IoT device manufacturers, automakers, and cloud/video streaming providers.

From a competitive standpoint, InterDigital occupies a specialized, high-value niche. Its differentiation comes from deep research capability, long-standing standards leadership, and the scale of its intellectual property portfolio, which continued to expand in 2025. The company emphasizes a broad licensing base and long-dated agreements, which support recurring revenue visibility and strengthen its position as a behind-the-scenes technology enabler rather than a conventional device or infrastructure vendor. ([ir.interdigital.com](https://ir.interdigital.com/news-events/press-releases/news-details/2026/InterDigital-Reports-Fourth-Quarter-and-Full-Year-2025-Financial-Results/default.aspx?utm_source=openai))
Recent developments underscore the strength of the business momentum. In February 2026, InterDigital reported strong full-year 2025 results, highlighting licensing traction and continued growth in its patent portfolio. In July 2025, quarterly revenue rose sharply, helped by the Samsung arbitration outcome and a new licensing agreement with HP. In Q1 2026, the company said it started the year strongly, including a long-term renewal with Xiaomi and additional licensing wins. Taken together, these updates suggest sustained execution in InterDigital’s core IP monetization strategy.
