EV Lightweight Body Patent Snapshot 2026
The EV lightweight body (standalone) patent corpus is extremely early-stage, with only 3 patent families in scope and activity concentrated in China. A handful of academic-industry collaborators and one global automaker define the field, leaving the assignee snapshot highly open.
A nascent field dominated by a single Chinese academic-industry cluster and Mazda
The top-ranked filer, the Institute of Dongguan Sun Yat-sen University, shares first position with Mazda Motor Corporation and Dongguan Sannew Electric Vehicle Technology, each holding 2 patent records. Jinling Institute of Technology accounts for 1 patent record.
The top five filers collectively account for 100% of the combined total across the ranked applicants visible in this query, indicating an extremely concentrated and embryonic field with no broad-based competitive activity yet visible.
| # | Applicant | Patent records | Share |
|---|---|---|---|
| 1 | Institute of Dongguan Sun Yat-sen University | 2 | |
| 2 | Mazda Motor Corporation | 2 | |
| 3 | Dongguan Sannew Electric Vehicle Technology Co., Ltd. | 2 | |
| 4 | Jinling Institute of Technology | 1 |
The leading positions of a Chinese university-linked institute alongside a Japanese OEM suggest that foundational structural work is being explored in parallel from both academic and automotive-engineering angles, but neither has established a substantial portfolio advantage.
Because patent applications typically appear in public databases 12–24 months after filing, very recent activity may be under-represented in this corpus. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Sporadic filing activity and a body-structure-dominant technology mix
Filing activity is sparse and irregular: no records appear before 2022, a small cluster emerged in 2022, and one further record appeared in 2024. The technology mix is anchored in motor-vehicle body engineering.
Annual filing trend
Recorded activity is limited to 2022 (2 records) and 2024 (1 record), with zero activity in all other years from 2017 to 2026. Years 2024–2026 should be treated with caution due to publication lag; the field’s actual recent activity may be higher than shown.

B62D (Motor vehicles and steering) is the visible branch with 5 patent records, followed by B60H (Vehicle heating and air conditioning) with 2. B60K (Vehicle propulsion and drive), G01N (Material analysis and testing), and G06F (Electric digital data processing) each contribute 1 record, indicating that the corpus reaches beyond pure structural work into thermal management, digital simulation, and materials testing.

The present disclosure relates to an electric-vehicle-body structure. To provide sufficient distortion stiffness of a vehicle body in a vehicle-body structure including no floor tunnel largely bulging upward from a floor panel and improve layout easiness of an air sending path of air-conditioned air, an electric-vehicle vehicle-body structure (A) includes… (excerpt from the patent abstract)

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Mazda Motor Corporation
Mazda holds 2 patent records with a technology focus spanning B62D 21 and B62D 25 (motor-vehicle body and steering structures) alongside B60H 1 (vehicle heating and air conditioning), suggesting an integrated approach to body architecture and thermal management. Momentum is flagged as a new entrant, indicating this is Mazda’s first filing activity in this specific topic cluster.
patent records: 2Institute of Dongguan Sun Yat-sen University
The Dongguan Sun Yat-sen University research institute holds 2 patent records, entirely focused on B62D 25 (motor-vehicle body structures). Its co-filing arrangement with Dongguan Sannew Electric Vehicle Technology positions it as the academic anchor of the only active collaboration in the field, bridging university research and commercial EV development.
patent records: 2Frequently asked questions
The evidence covers 3 patent families in scope. This is an extremely small corpus, indicating the topic as a standalone search is at a very early stage of IP development.
The top filers are the Institute of Dongguan Sun Yat-sen University, Mazda Motor Corporation, and Dongguan Sannew Electric Vehicle Technology, each with 2 patent records, followed by Jinling Institute of Technology with 1 patent record.
China accounts for all 3 patent families in the corpus. At the patent-record level, Europe (EPO) also shows 2 records, reflecting Mazda’s parallel European filings. No other jurisdictions are represented in the evidence.
B62D (Motor vehicles and steering, covering body and structural elements) is the visible class with 5 patent records. B60H (Vehicle heating and air conditioning) follows with 2 records, and B60K, G01N, and G06F each contribute 1 record.
One co-filing pair is documented: the Dongguan Sun Yat-sen University research institute and Dongguan Sannew Electric Vehicle Technology co-filed 2 patent records together. No other collaborative relationships appear in the evidence.
Filing activity is sparse: no records appear before 2022, 2 records emerged in 2022, and 1 further record appeared in 2024. Given the standard 12–24 month publication lag, the true recent pace may be somewhat higher than shown, but the overall picture is one of very limited and intermittent activity.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
