This past December, CDN Innovations, LLC filed a Western District of Texas complaint against Sercomm (6:23-cv-00873), targeting the provision of networking products (e.g., gateways, modems, and routers) that implement port triggering with two patents generally related to detecting computer port inactivity. Early this year, Sercomm USA, a California-based subsidiary of the Taiwanese parent, filed a Northern District of California complaint against CDN Innovations (4:24-cv-00174). There, Sercomm USA seeks declaratory judgments of license, estoppel, and/or exhaustion for both patents, contending that CDN gave licenses and/or certain covenants to, or otherwise resolved claims against, Broadcom and MediaTek, asserting that because the accused products incorporate certain integrated circuits (ICs) and software from “Broadcom and/or MediaTek”, CDN is “barred, exhausted, and/or estopped” from alleging infringement.
