Context: In May 2023, Malikie Innovations, a subsidiary of Irish non-practising entity (NPE) Key Patent Innovations, acquired a majority of BlackBerryâs non-core patents and patent applications (roughly 32,000) related to mobile devices, messaging, and wireless networking for $200 million. Meanwhile, Valtrus was created by Key Patent Innovations to manage and monetize data center patents acquired from Hewlett-Packard Enterprise (HPE) in January 2021. Both entities have been highly active NPEs. Valtrust asserted its portfolio against Google, Microsoft, and Meta, while it has found itself on the defendant side of a DJ of non-infringement and invalidity case brought by Starbucks in the United States District Court for the Western District of Washington (September 26, 2025 ip fray article). Malikie has also initiated disputes against Nintendo (which the two settled last year: December 2, 2025 ip fray article), Canon, D-Link, OPPO (in the Unified Patent Court: (March 1, 2026 ip fray article), and, most recently, Brother Industries.
Whatâs new: Key Patent Innovations, Malikie, and Valtrus have launched a multi-patent infringement campaign against seven different companies, including Hisense and NTT Global Data, in the United States District Court for the Eastern District of Texas and Northern District of Illinois. Some of the complaints and a full breakdown of each of the suits are below the box. Hisense has been sued over four different multimedia and communications patents, while NTT and the remaining defendants (STACK, EvoDC, LLC, Netrality Properties, CoreSite, LLC, Prime Data Centers, LLC, and Lumen Technologies) have been sued over data center-related patents.
Direct impact and wider ramifications: While the companies have historically been active enforcers, this wave of new patent infringement suits indicates that they are upping their efforts to monetize their portfolios even further. Interestingly, Blackberry yesterday announced it has joined Sisvelâs new Point of Sale (POS) patent pool (April 9, 2026 Sisvel LinkedIn post), after reporting it made $21 million in licensing revenue in FY2026 (a bit of a plunge from the previous year). And, separately, HPE announced it too had joined a Sisvel pool (although as a licensee: April 8, 2026 ip fray article).
