Robotic Lawn Mower Patents: Filing Trends and Where Claim Space Is Still Open
Concentrated at the top. The five leading assignees together hold 59.4% of all 1,336 records in scope, and the ranked ten hold 75.4% — a small group has occupied most of the core claim space. Filings climbed from 35 in 2017 to a peak of 215 in 2020, then eased to 171 in 2021 and 73 by 2024 — a -57% move over that three-year span. Years after 2024 are still incomplete in the record and should not be read as a continued slide.

Common questions about robotic lawn mower patents
Who holds the most robotic lawn mower patents?
One assignee leads the ranked field with 240 records out of 1,336 in scope, well ahead of the fifth-place holder at 50. The top five assignees combined hold 59.4% of all records, and the top ten hold 75.4%, so the field is concentrated among a small group rather than evenly spread across the 100 ranked companies. A new entrant should expect the leader’s portfolio to be the primary obstacle in core mowing and navigation claims, with the remaining ranked companies covering narrower or more defensive positions.
Is the robotic lawn mower patent market still growing?
Filings peaked in 2020 at 215 and have since eased, with complete-year data showing a drop from 171 in 2021 to 73 in 2024, a -57% change. That looks like normalisation after an unusually sharp filing surge rather than the field shrinking outright. Figures for 2025 and 2026 are still incomplete because publication typically lags actual filing by around 18 months, so the most recent years should not yet be read as continued decline.
What technologies do robotic lawn mower patents actually cover?
Two IPC classes dominate: A01D, covering mowing and harvesting mechanics, appears in 58.9% of the 1,336 records, and G05D, covering control of non-electric variables such as navigation and path planning, appears in 54.4%. Smaller but active shares fall in B25J manipulators, G01S positioning, B60L propulsion, G06V image recognition and A01B soil-working, meaning a typical filing in this field usually combines mechanical mowing claims with navigation or control claims rather than covering either alone.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
