Extreme Networks Added to Winterspring Digital’s Networking Campaign
New Patent Litigation
Winterspring Digital LLC has expanded its campaign over former Intellectual Ventures LLC (IV) patents with a suit against Extreme Networks (2:23-cv-00374) in the Eastern District of Texas. The asserted patents are broadly directed to various aspects of networking, with Extreme Networks targeted over products (e.g., computers, endpoint solutions, firewalls, modules, switches, and transceivers) that “receive, convert, monitor, and send 10GE LAN signals” or perform “packet tagging”.

WinterSpring Digital Expands Campaign over Former IV Patents
New Patent Litigation
Winterspring Digital LLC has filed separate suits against Check Point Software Technologies (2:23-cv-00244), Fujitsu (2:23-cv-00269), HP Enterprise (HPE) (2:23-cv-00259), and Lenovo (2:23-cv-00258) in the Eastern District of Texas, targeting products (e.g., computers, endpoint solutions, firewalls, modules, switches, and transceivers) that “receive, convert, monitor, and send 10GE LAN signals” or perform “packet tagging”. The two asserted patents, broadly directed to network communications, are among four former Intellectual Ventures LLC (IV) patents that have been asserted against 11 defendants—also including Broadcom, Fortinet, Marvell Technology, MediaTek, Microchip Technology, Palo Alto Networks, Renesas, and Trend Micro—in this, the plaintiff’s sole litigation campaign.

Winterspring Digital Campaign Snags Another Pair of Defendants
New Patent Litigation
Winterspring Digital LLC has filed another pair of complaints, accusing Marvell (2:23-cv-00024) and Renesas Electronics (2:23-cv-00025) of infringing three patents described by the plaintiff as generally related to “routing data over a network”. The plaintiff targets the provision of Ethernet network adaptors and controllers, PHYs, ethernet switches, and/or optical modules that “receive, convert, monitor, and send 10GE LAN signals”; “implement packet tagging”; and allow for “traffic admission control using real time bandwidth allocation”. The same three patents are asserted in complaints filed earlier this month against MediaTek and Microchip Technology, also in the Eastern District of Texas.

Winterspring Revives Networking Campaign with Suits Against MediaTek and Microchip
New Patent Litigation
Winterspring Digital LLC has expanded its sole litigation campaign over former Intellectual Ventures LLC (IV) patents with separate suits against MediaTek (2:23-cv-00012) and Microchip Technology (2:23-cv-00013) in the Eastern District of Texas. The three patents-in-suit, with one asserted in litigation for the first time, are described as generally related to “routing data over a network”. The defendants are accused of infringement over a wide array of devices (e.g., ASICs, ethernet switches, microchips, SoCs, and transceivers) that “receive, convert, monitor, and send 10GE LAN signals”; “implement packet tagging”; and allow for “traffic admission control using real time bandwidth allocation”.

New Patent Litigation
In its latest complaint, Winterspring Digital LLC asserts the same three former Intellectual Ventures LLC (IV) patents, described as generally related to “routing data over a network”, this time against Broadcom (2:22-cv-00402). The NPE targets the provision of various Ethernet networking devices and network management software for the inclusion of various features, including support for 10-Gigabit Ethernet (10GE), packet tagging, and network management GUIs. This campaign, begun in January 2022, has yet to see an answer filed.
