Who is building the most defensible V2X IP – and in which direction?
Cars used to be islands. Now they’re learning to talk – to each other, to traffic signals, to the road itself, and to the cloud. Familiar names like Qualcomm, Huawei, and Samsung are racing alongside automakers like Toyota, Ford, and Hyundai to own that conversation.
This report ranks 50 companies based on US patent publications filed after January 1, 2023, covering V2X (vehicle-to-everything) technology – spanning cellular and short-range vehicle communications, roadside and network infrastructure, cooperative driving and safety applications, connected-vehicle computing, and fleet telematics. It’s the same patent-first approach behind GreyB Spotlight, our program recognizing the top 1% of innovators across industries.
This ranking follows the same patent-first evaluation behind GreyB Spotlight, our program recognizing the top 1% of innovators across 23+ industries – no applications, no nominations, evidence only.

A note on ranking & company scope
Not everyone here builds connected-car technology for a living. Some show up because a single division, subsidiary, or patent-holding entity is quietly filing in this space – in wireless connectivity, roadside and network infrastructure, cooperative driving, connected-vehicle computing, or fleet telematics. That’s the nature of V2X IP: it cuts across automakers, chipmakers, telecom and device companies, software platforms, and fleet-data firms alike. A few entries are not operating technology companies: Acquiom Agency Services Llc is a loan-agency firm, and Bunker Hill Technologies Llc is a patent-assertion entity. Others, such as GM Global Technology Operations Llc and Magna Mirrors, are group entities distinct from the parent brand most people recognize. Each is noted individually in the accompanying verification log.
