SolutionInc Limited, a Canadian provider of networking products for the hospitality industry, has filed a February round of lawsuits—against Avaya (1:20-cv-00185), Cisco (1:20-cv-00145), Extreme Networks (1:20-cv-00186), Huawei (1:20-cv-00146), Nokia (1:20-cv-00187), and Samsung (1:20-cv-00147)—following four December 2019 cases, hitting ARRIS (Ruckus Networks f/k/a (Ruckus Wireless)), HP Enterprise (HPE) (Aruba), NETGEAR, and Zyxel. Targeted are features within the defendants’ Wireless LAN solutions that allow guest access to a Wi-Fi network: for example, using a captive portal page, using the Address Resolution Protocol (ARP) to verify that traffic is being sent to the correct IP address, etc. As SolutionInc’s campaign gains steam, two other full-blown patent infringement disputes—one in the guise of a lawsuit over the breach of a prior license agreement—have also been ramping up between two other hospitality networking service providers, Guest-Tek and Nomadix. Nomadix launched a large campaign in this space roughly a decade ago in which it sued a host of defendants, including both Aruba and SolutionInc—a campaign that Nomadix, under new ownership, has also recently revived.
