Keysight Technologies, Inc.

Keysight Technologies, Inc. is a publicly traded company (NYSE: KEYS) that designs and manufactures electronic test and measurement equipment and software. Headquartered in Santa Rosa, California, the company was founded on November 1, 2014, as a spin-off from Agilent Technologies, which itself originated from Hewlett-Packard. For its 2023 fiscal year, Keysight reported revenues of $5.46 billion and employed approximately 16,800 people as of 2025.

As a major operating company, Keysight provides a wide range of solutions across various industries, including communications, aerospace and defense, automotive, and semiconductors. Its product portfolio includes instruments such as oscilloscopes, network analyzers, signal generators, and spectrum analyzers, as well as electronic design automation (EDA) software under its PathWave brand. These tools are used by engineers in design, development, manufacturing, and network monitoring.

Keysight’s litigation profile is primarily that of an operating company defending itself against patent assertions. The tracked case data shows two instances of Keysight as a defendant and one as a plaintiff, all related to the same adversary. This pattern indicates a targeted defensive posture rather than that of a frequent litigant. When sued for infringement, the company has shown a willingness to challenge the validity of the asserted patents, a common strategy for operating companies.

The company's tracked patent cases all stem from a multi-forum dispute with cybersecurity firm Centripetal Networks, LLC. Centripetal initiated actions against Keysight in 2022 in the U.S. International Trade Commission and the U.S. District Court for the Eastern District of Virginia, alleging infringement by Keysight's network security products. In response, Keysight filed a proceeding at the USPTO's Patent Trial and Appeal Board (PTAB) to challenge the validity of Centripetal's patents. In April 2026, the U.S. Court of Appeals for the Federal Circuit affirmed rulings from both the ITC and PTAB in favor of Keysight, clearing it of infringement claims and invalidating numerous asserted patent claims.
