Nielsen Co US LLC is part of Nielsen Holdings, a global leader in audience measurement, data, and analytics, founded in 1923 by Arthur C. Nielsen Sr.. Headquartered in New York City, Nielsen Holdings operates in over 100 countries and employs approximately 15,000 to 44,000 people worldwide, though some sources indicate as many as 50,000 employees.. The company was publicly traded on the NYSE as NLSN until October 2022, when it was acquired for $16 billion by a consortium of private equity firms led by Elliott Investment Management (through its affiliate Evergreen Coast Capital Corp.) and Brookfield Business Partners, making it a privately held entity..
Nielsen specializes in measuring what consumers watch, listen to, and buy, providing data collection, analysis, and reporting services for television, radio, and digital media.. Key offerings include television audience measurement, digital audience measurement, mobile measurement, and services for media planning and marketing optimization.. The company's expertise helps businesses and markets understand audience engagement and consumer behavior, making informed decisions in media consumption, advertising effectiveness, and retail performance.. Nielsen also provides metadata support services and supplies viewership and ratings data to various government agencies..
Nielsen Co US LLC primarily maintains a defensive patent litigation posture, as indicated by its single appearance as a defendant and zero as a plaintiff in the tracked case data. The company is currently involved in one case, Unified Patents v. Nielsen Co US LLC, at the Patent Trial and Appeal Board (PTAB) in 2026, where it is a defendant. This suggests Nielsen is an operating company facing patent challenges, rather than asserting patents itself.
The case against Nielsen Co US LLC by Unified Patents is a notable interaction. Unified Patents is an organization that challenges patents asserted by Non-Practicing Entities (NPEs) or to deter frivolous patent litigation, often filing inter partes reviews (IPRs) at the PTAB.. While the specific details of the patent in question are not available in the provided data, the nature of Unified Patents' activities suggests the case likely involves a challenge to a patent held or asserted against Nielsen, consistent with Nielsen's role as a defendant in the matter..
