Modular / Containerized BESS Patent Snapshot 2026
The modular and containerized battery energy storage system (BESS) patent space comprises 26 patent families, led by Veloce Energy Inc with 4 families — a highly fragmented, early-stage field where no single player has established dominant coverage. The United States is the primary jurisdiction, and the applicant pool is predominantly composed of new entrants, signaling an emerging competitive window rather than an entrenched evidence snapshot.
Veloce Energy leads a nascent, fragmented field
With 26 patent families in scope, modular and containerized BESS is an early-stage technology area. Veloce Energy Inc holds the largest position at 4 patent families, followed by Redwood Materials Inc and Honda Motor Co., Ltd., each with 3 patent families, and Vestas Wind Systems and Honeywell International each with 2.
The top five filers account for 58% of the ranked applicants visible in this query’ combined total — a notable concentration figure for a corpus this small, but the absolute counts are low enough that the field remains genuinely open. No applicant has built the deep, multi-family thicket that typically signals a locked-down technology position.

The diversity of organizational types at the top — a venture-backed startup (Veloce Energy), a battery recycler (Redwood Materials), an automaker (Honda), a wind OEM (Vestas), and an industrial conglomerate (Honeywell) — reflects that the technology has not yet consolidated around a single industry vertical. This creates cross-sector entry opportunities.
Filing data for the most recent 18–24 months should be treated as incomplete due to standard patent publication lag; the apparent 2026 zero and modest 2024–2025 counts likely understate actual recent activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Sporadic filing history with a recent uptick; battery cell IP dominates
The annual filing trend and technology composition together reveal a field that has emerged in distinct bursts rather than steady growth, anchored almost entirely in battery cell and grid-integration IP.
Annual filing trend
Filings were negligible from 2017 through 2021, surged to 7 families in 2022, dipped in 2023, and then recorded 3 families in 2024 and 10 in 2025. The 2025 figure is the highest single-year count on record, though it should be interpreted cautiously given publication lag — the true 2024–2025 contribution may be higher still. The 2026 zero reflects an incomplete year, not an absence of activity.

H01M (Batteries, cells and fuel cells) covers all 26 families, confirming that cell-level chemistry and pack design are the universal foundation. H02J (Power supply and grid systems) appears in 14 records, reflecting significant interest in how modular BESS integrates with electrical infrastructure. B60L (Electric vehicle propulsion) appears in 6 records, indicating overlap with EV charging and mobile storage use cases. All other branches — measurement, printed circuits, fire-fighting, containers, conveying, building structures, drilling, control systems, signalling, and capacitors — each appear in 5 or fewer records, underscoring how narrow the current IP footprint is outside the core battery and grid classes.

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.
Veloce Energy Inc
Veloce Energy Inc holds 4 patent families — the largest position in this corpus — and is classified as a new entrant (trend: new entrant), indicating all activity is recent. Its technology focus spans B60L 53 (electric vehicle propulsion and charging), H01M 10 (battery cells), and H02J 7 (power supply and charging systems), pointing to a strategy centered on mobile and EV-integrated modular storage rather than purely stationary grid applications.
families: 4Redwood Materials Inc
Redwood Materials Inc holds 3 patent families and, like all tracked applicants, is a new entrant. Its technology emphasis covers H01M 10 (battery cells), H02J 3 (grid power systems), and H02J 7 (charging systems), suggesting an approach that integrates battery material and second-life considerations with grid-facing storage architectures — consistent with its core recycling and materials business.
families: 3Frequently asked questions
The current dataset contains 26 patent families in scope for modular and containerized battery energy storage systems. This is a small corpus, consistent with an early-stage technology area.
Veloce Energy Inc leads with 4 patent families, followed by Redwood Materials Inc and Honda Motor Co., Ltd. each with 3 patent families. All momentum-tracked applicants are classified as new entrants, indicating the competitive hierarchy formed recently.
The United States leads with 9 patent records, followed by Europe (EPO) and WIPO (PCT) each with 5, and China with 2. Australia, Canada, the United Kingdom, India, and Taiwan each have 1 record. PCT filings indicate some applicants are maintaining global optionality.
H01M (Batteries, cells and fuel cells) covers all 26 families, making it the universal foundation. H02J (Power supply and grid systems) appears in 14 records, and B60L (Electric vehicle propulsion) in 6, reflecting overlap with EV charging applications.
No co-applicant or joint-filing relationships are detected in the current dataset. All identified filers appear to be pursuing independent proprietary positions, and no consortium or standards-body filing structures are evident.
The sparsest adjacent branches relative to the core corpus are G01R (electric and magnetic measurement, 5 records), H05K (printed circuits and assemblies, 2 records), A62C (fire-fighting, 1 record), B65D (containers and packaging, 1 record), and B65G (conveying and material handling, 1 record). Battery diagnostics and fire suppression are the two branches with the clearest combination of sparse IP and high technical relevance to containerized deployment.

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.
