1 case as defendant.
Xirrus, Inc. is a former enterprise Wi-Fi networking company headquartered at 2101 Corporate Center Drive, Thousand Oaks, California. It was founded in 2004 by Dirk Gates (co-founder of Xircom), Patrick Parker and Steve DeGennaro; some sources cite a 2002–2003 origin. Xirrus was private and venture-backed, raising roughly $95–130 million from investors including August Capital, Canaan Partners, InterWest Partners, QuestMark Partners and US Venture Partners. Thomasnet historically listed annual sales in the $50–99.9M band with 200–499 employees, though no audited figure is public. It is now defunct as an independent entity.
Products / operations. Xirrus designed and manufactured enterprise wireless LAN equipment built on its multi-radio "Wi-Fi Array" architecture, which bundled a controller, high-gain directional antennas and 4–24 radios into a single device. Product lines included the XD, XA, XR and XN series access points and arrays, plus cloud and subscription services such as XMS Cloud Management, EasyPass Access, Application Control, the Xirrus Positioning System (XPS) and MSP Command Center. Customers were concentrated in education, healthcare, hospitality, government and high-density public venues.
Ownership history. Riverbed Technology acquired Xirrus in April 2017 to extend its SteelConnect SD-WAN offering to the wireless edge. In August 2019, Cambium Networks (NYSE: CMBM) purchased the Xirrus Wi-Fi products and cloud services portfolio from Riverbed.
Patent-litigation posture. Xirrus appears once in the tracked data, solely as a defendant — consistent with an operating company defending against assertion, not an NPE. The single case, XR Communications, LLC v. Xirrus, Inc., No. 3:17-cv-00675, was filed in the U.S. District Court for the Southern District of California on April 3, 2017 and closed April 7, 2017. Plaintiff XR Communications is characterized in Stanford's NPE Litigation Database under a "failed startup" asset profile; the suit asserted Vivato-origin patents (including U.S. 7,062,296 on forced beam switching) against Xirrus MU-MIMO / 802.11ac access points. The case was filed in San Diego, not the Eastern District of Texas.
2017 Southern District of California case listed in the Stanford NPE Litigation Database and identified as part of the wave asserting the '231 patent along with U.S. 7,062,296 and 7,729,728; outcomes were not confirmed in the retrieved records.
