Earlier this year, the final dust settled on 2013 cases that Parallel Networks Licensing, LLC filed against IBM and Microsoft, after the Federal Circuit ruled on an appeal from an award of costs to Microsoft (20-1669). Now, litigation has ginned back up, the plaintiff suing Arrow Electronics (4:21-cv-00714) in the Eastern District of Texas and Artisan Infrastructure (6:21-cv-00951), SHI International (6:21-cv-00953), and Transtelco (Neutrona Networks International) (6:21-cv-00952) in the Western District, alleging infringement of the same two dynamic webpage creation patents that have been in suit in this campaign since 2005. At issue in these latest complaints is the use of various hardware and software products (i.e., Application Delivery Controllers (ADCs), load balancers, firewalls, and router management software, respectively) that feature a “least-connected load balancing” mode—products provided by nonparties A10 Networks (as to Arrow), Kemp Technologies (Artisan), Barracuda Networks (SHI), and Juniper Networks (Neutrona).
