Battery Outdoor Power Equipment Patents: Leaders & White Space 2026
- One assignee dominates the ranked field. the leader holds 15 records against a fifth-place and tenth-place count of 2 apiece, a steep drop-off rather than a gradual tail.
- Filing activity peaked in 2018 at 4 records and the 2021→2024 span shows a -100% swing, though 2025-26 counts are still filling in under normal publication lag.
- Motor control and pump/blower hardware rival horticulture itself A01G horticulture leads at 27.7% of the 47 records, but F04D pumps and H02K motors each sit at 19.1%.
Filing growth compares 2021 (4 records) with 2024 (0) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field.
What this landscape covers
This review scopes 47 published records at the intersection of battery-powered mowers, garden tools and broader outdoor power equipment, filtered against practical claims around runtime per charge, power equivalence to gas equipment, noise reduction, weight balance, battery interchange and professional duty ratings. The search string targets records that combine a battery/outdoor-equipment term with one of these performance or design constraints, so the set skews toward claims that address real deployment trade-offs rather than generic electrification.
Coverage runs from 2015 through the 2026-07-31 cut-off. Because publication lags filing by roughly 18 months, the most recent one to two years understate true filing activity and should not be read as a slowdown.

Filing trend and technology composition
Two views of the same 47-record set: when the filings happened, and which IPC subclasses they carry.
Filing trend, 2017-2026
Activity opened at 1 record in 2017, rose to a peak of 4 in 2018, and the 2021-to-2024 span moved from 4 down to 0, a -100% change over that three-year window. 2025 and 2026 are still incomplete under normal publication lag and should not be read as a decline on their own.
IPC subclass composition
A01G horticulture and forestry equipment leads at 27.7% of the 47 records in scope. F04D non-positive-displacement pumps and H02K electric motors and generators are tied at 19.1% each, followed by G05B control systems and H02P motor control at 10.6% apiece, and A01D harvesting, A47L cleaning appliances and F01N exhaust silencing at 8.5% each. Records can carry more than one class, so these shares sum above 100%.
Shares are the percentage of the 47 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Outdoor power equipment with distributed motor controllers
An outdoor power equipment includes multiple motors and a controller module. The motors include a first motor and a second motor, each structured to operate a distinct component of the equipment. The controller module includes multiple motor controllers that communicate via a network communication bus with each other and operate the first and second motors based on that communication.Filed by Briggs & Stratton, published 2020-01-16.

Three findings that shape where a new filing would sit relative to existing claim space.
One filer, then a steep drop
The ranked leader holds 15 records while fifth place holds only 2 and tenth place also holds 2. That is not a long gradual tail; it is a single dominant filer sitting well above a thin, closely bunched group of smaller players.
Motors and pumps carry real claim weight
F04D pumps and H02K motors and generators each account for 19.1% of the 47 records, nearly matching A01G horticulture's 27.7%. Battery outdoor power equipment claims are as much about drivetrain and airflow hardware as about the power source itself.
Peak activity was 2018, not recent years
The dataset's peak year so far is 2018 at 4 records, and the 2021-2024 span moved from 4 down to 0. Given the roughly 18-month publication lag, 2025-26 figures are still incomplete and should not be treated as confirming a slowdown.
Filing is concentrated in the US, with PCT as the secondary route
The United States receiving office accounts for 26 of the tracked filings, with WIPO PCT applications at 8 and EPO at 5. Germany, China and Austria each show smaller counts, indicating this is primarily a US-anchored filing pattern with selective international extension.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to battery outdoor power equipment, with the prior art for and against each one.
Who is filing, and where the gaps sit
The ranked field is short — 16 companies — and dominated by one filer, with individual inventors also appearing as named co-assignees.
A single filer sets the pace
The top-ranked assignee holds 15 of the records in this ranking, well ahead of the rest of the field. Recent-year momentum for this leader and several other tracked assignees shows 0 in the latest year, consistent with the publication lag rather than a stop in activity.
A thin, closely bunched middle
Fifth place and tenth place both hold 2 records apiece, meaning the gap between the leader and everyone else is far larger than the gap within the mid-field itself. This points to one company having built an early position rather than several firms racing evenly.
Individual inventors co-file repeatedly
Among the 10 co-assignee pairs identified, the strongest links each appear 3 times and connect the same small group of named individuals rather than corporate teams, suggesting a compact inventor network working the same claim areas.

Where to take this analysis
The dataset points to a concentrated leader, hardware-heavy claim composition, and filing activity that predates the most recent reporting years.
Check freedom-to-operate against the leader's portfolio
With one assignee holding 15 records against a thin mid-field, any new filing in motor control, noise reduction or battery interchange should be checked against that leader's claims first.
Explore assignee claims in EurekaWatch the under-claimed sub-areas
Professional-duty certification and distributed controller networking sit outside the densest classes and may offer more room for a first-mover claim.
Map white space in EurekaRe-run the trend once 2025-26 fills in
Because publication lags filing by about 18 months, the current 2025-26 dip is not a reliable signal yet; a re-check in a year will show whether 2021-2024 momentum resumed.

In this dataset of 47 records, one assignee leads the ranked field with 15 records, well ahead of the rest of the 16 companies tracked. Fifth place and tenth place each hold only 2 records, so the gap between the leader and everyone else is much wider than the gaps within the rest of the field. This pattern suggests an early filer that built a broad position before competitors caught up, rather than several companies racing at similar pace.
The peak filing year so far is 2018 with 4 records, and the 2021-to-2024 span shows a -100% change. However, publication typically lags actual filing by around 18 months, so the 2025 and 2026 figures in any dataset are still incomplete and should not be read as proof of a slowdown. A fair read of momentum needs another year or two of data before the most recent years can be trusted.
Horticulture and forestry equipment (IPC class A01G) is the largest single class, covering 27.7% of the 47 records in scope. Non-positive-displacement pumps (F04D) and electric motors and generators (H02K) are tied close behind at 19.1% each, showing that drivetrain and airflow hardware are claimed almost as heavily as the horticultural application itself. Control systems (G05B and H02P) and noise-related classes (F01N) also appear, reflecting the runtime, noise and power-equivalence constraints built into the search.
Sub-areas such as battery pack interchange across different tool lines, professional-duty runtime certification, and weight-balance engineering for handheld professional tools show up less densely than the core motor and horticulture classes. These are not zero-filing areas, but they sit outside the highest-density classes (A01G, F04D, H02K), which is where a first, carefully drafted claim has more room to stand without immediately colliding with existing dense prior art.
US20200021210A1, filed by Briggs & Stratton and published 2020-01-16, claims outdoor power equipment using multiple motors, each driving a distinct component, coordinated by a controller module with multiple motor controllers communicating over a network bus. The claim scope centers on the distributed control architecture, not the individual motors themselves. Anyone building networked or multi-motor control schemes for outdoor power equipment should review this filing closely before finalizing a controller architecture.
