INTERDIGITAL INC.

INTERDIGITAL INC. is a technology licensing company in the Patent Owners & Lessors sector, building a global portfolio of wireless and video communications patents that supports patent-intensive blockchains of standard-essential technologies; it focuses on licensing its intellectual property to manufacturers, wireless carriers, and chipset developers that build CDMA, 3G, LTE, and 5G infrastructure, and it also offers related services such as patent portfolio management and advisory work, drawing on a storied history of contributions to international telecommunications standards. The firm’s revenue depends on the continued strength and enforcement of its patents, making its customers highly regulated device makers who must comply with worldwide licensing requirements and antitrust scrutiny; changes to standard-setting policies, royalty rate disputes, or unfavorable court decisions could materially affect cash flow. The company highlights in CIK 354913 and its most recent Form 10-Q filed in November 1999 that it remains vigilant about litigation costs, regulatory shifts, and patent expirations, so visit Earnings Feed to view live SEC filings and stay informed.
