XR Communications, LLC, which does business as Vivato Technologies, is a Delaware limited liability company with a principal place of business at 2809 Ocean Front Walk, Venice, California 90291, according to complaints filed in its cases. It is privately held with no public ticker and no disclosed parent; headcount and revenue figures are not published, and the entity files no financial statements, so size cannot be verified.
Operations. XR Communications is a patent-holding and patent-assertion entity, not an operating company — it does not manufacture or sell products. Its portfolio derives from Vivato Inc./Vivato Networks, a venture-backed (reported $80M+) Wi-Fi infrastructure developer founded in 2000 that built beamforming phased-array access points. After Vivato Networks defaulted on secured loans from Aequitas Capital, Aequitas sold the patent portfolio to XR Communications in December 2009. XR's own complaints describe a portfolio of 17+ issued patents and applications covering adaptive/steered antenna arrays, beamforming, forced beam switching, and "Directed MIMO"/MU-MIMO wireless communication. Asserted patents include U.S. 6,611,231; 7,062,296; 7,729,728; 7,177,369; 8,289,939; 8,737,511; 10,594,376; 10,715,235; 11,750,256; and 11,777,569. It appears in Stanford's NPE Litigation Database.
Litigation posture. XR is a one-way plaintiff: 14 of 16 tracked cases list it as plaintiff, and its two "defendant" entries are Ericsson-filed PTAB proceedings where XR is the patent owner. It asserts an acquired portfolio rather than defending products.
Notable cases. The tracked cases are a 2017 C.D. Cal./S.D. Cal. campaign against Wi-Fi vendors (D-Link, NETGEAR, Belkin, Cisco, Aruba, Extreme Networks, Ruckus, Ubiquiti, Xirrus, Newo/Amped Wireless) plus an N.D. Cal. suit against ARRIS, generating nine 2018 IPRs by Aruba, Cisco, Ruckus/ARRIS/NETGEAR/Belkin. In Cisco Systems v. XR Communications (Fed. Cir. 2020, No. 20-1105) the Board's no-obviousness holding on the '231 patent was affirmed. Public dockets also show later suits against AT&T, Verizon, and T-Mobile in E.D. Tex.
