Company profile

CommWorks Solutions, LLC is a patent-holding entity, not an operating company. It is a Delaware-style LLC whose Rule 7.1 filings in recent cases identify Brainbox Innovations, LLC as its corporate parent; Unified Patents has described it as an NPE and a subsidiary of IP Investments Group LLC (the two are used interchangeably in coverage of the same portfolio). Its name derives from the former CommWorks carrier-networking division of 3Com, which 3Com sold to UTStarcom in 2003 for roughly $100 million in cash; the asserted patents trace to that networking lineage and to later transfers (IPWatchdog reported Intellectual Ventures as transferor, with an alleged retained security interest/backend on licensing revenue). Headquarters, employee count, and revenue are not disclosed in any source I could verify — the entity appears to have no products, staff, or operations.

Products / services. None. CommWorks Solutions makes and sells nothing. It monetizes an acquired patent portfolio through litigation. The asserted patents center on broadband and networking technology: multilayer internet communication with QoS/priority control (U.S. 6,832,249), Ethernet switching and IEEE 802.3ah EFM, DSL/GPON access, and wireless/WMM QoS (U.S. 7,027,465, RE44,904, 7,177,285, 7,463,596, 7,911,979, 6,891,807, 7,760,664, 8,116,315), plus mobile-network information recovery (U.S. 8,923,846, invalidated by the PTAB in a Unified Patents IPR in February 2023).

Litigation posture. Purely offensive. The tracked data show 48 cases as plaintiff and zero as defendant — the classic NPE signature. Filings cluster in plaintiff-friendly venues: the Eastern District of Texas (Judge Rodney Gilstrap), the Western District of Texas Waco Division (Judge Alan Albright), and other W.D. Tex. divisions, with occasional out-of-district filings (S.D.N.Y., D. Minn., N.D. Ga.).

Notable cases. Earlier campaigns targeted cable/broadband ISPs — Comcast, RCN Telecom, Charter, Consolidated Communications, Cable One, Mediacom — and drew a declaratory-judgment response from Altice USA in 2021. More recent suits target chipmakers and CPE vendors: Qualcomm, MediaTek, Texas Instruments, Marvell, STMicroelectronics, Microchip, ASUSTeK, VTech, AVM, DrayTek, ZyXEL, Hitron, Ubee, Grandstream, and Digi International. Several cases were voluntarily dismissed without prejudice before any merits ruling (e.g., Marvell, STMicroelectronics, EarthLink).
