800V HV Safety & Isolation Patent Snapshot 2026
The indexed corpus for 800V HV Safety / Isolation currently contains a single patent family, filed in 2024 and held by one Chinese applicant, indicating that this query scope is at a very early or narrowly defined stage. The competitive structure is effectively unconcentrated by incumbent portfolios, leaving the field open for systematic prior-art mapping and broader search refinement.
Single filer holds the entire indexed position
The applicant ranking is led by Bozui Technology (Suzhou) Co., Ltd., the sole filer in the current corpus, holding all patent families retrieved under this query.
With one applicant accounting for the entirety of the top-ranked filers, there is no measurable tier gap — the field as currently indexed has no second-tier challengers or diversified portfolio holders.
| # | Applicant | Patent families | Share |

The leader’s position reflects a single 2024 filing rather than an accumulated portfolio, which means incumbency advantages are minimal and the evidence snapshot is effectively open to new entrants with broader search coverage.
Results reflect patent families indexed at the time of retrieval; the most recent 18–24 months are subject to publication lag and the corpus may expand substantially as broader search terms are applied. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single 2024 filing defines the current trend baseline
The annual filing trend and technology composition together describe a corpus at its earliest observable stage, with activity confined to one year and one IPC class.
Annual filing trend
Filing activity is flat from 2017 through 2023 and 2025–2026, with a single family appearing in 2024. The 2025 and 2026 data points are subject to publication lag and should not be read as confirming zero activity.

All indexed activity falls under B60L (Electric vehicle propulsion), specifically sub-classes covering EV propulsion and battery systems. No other IPC branches are represented in the current corpus, which likely reflects the narrow query scope rather than the true breadth of 800V isolation technology.

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.
Bozui Technology (Suzhou) Co., Ltd.
Bozui Technology (Suzhou) Co., Ltd. holds 1 patent family in the current corpus, filed in 2024, marking the company as a new entrant (trend: new entrant). Its technology focus is concentrated in B60L sub-classes covering electric vehicle propulsion and battery systems, consistent with 800V EV powertrain safety applications.
families: 1No challenger identified
No second-ranked applicant is present in the current corpus. The challenger tier is unpopulated at this query scope. Broadening the search to include related IPC classes and keyword variants is expected to surface additional filers from established automotive Tier 1 suppliers and semiconductor isolation IC vendors.
families: evidence pendingFrequently asked questions
The current indexed corpus contains 1 patent family. This reflects the specific query scope used and is expected to grow substantially if broader keyword and IPC combinations are applied.
Bozui Technology (Suzhou) Co., Ltd. is the sole ranked applicant in the current corpus, holding the only indexed patent family, filed in 2024.
The only jurisdiction represented in the current corpus is China. Major 800V EV markets including the United States, Germany, South Korea, and Japan show no filings under this query scope.
All activity in the current corpus falls under B60L (Electric vehicle propulsion), specifically sub-classes related to EV propulsion systems and battery management.
The life-cycle stage cannot be determined from the current corpus of one patent family. A broader search is needed to establish whether the field is nascent, growth-stage, or maturing.
No co-filing activity is recorded in the current corpus. The collaboration dataset is empty, consistent with having a single applicant. Broader search results may reveal industry–university or cross-company partnerships in adjacent areas such as isolation IC development or EV safety standards implementation.

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.
