Blower & Debris Equipment Patents: Top Companies & Trends 2026
Blowers and Debris Handling Equipment: Where Patent Filings Concentrate and Where They Don't
Filings roughly tripled in three years. recorded filings climbed from 6 in 2021 to 20 in 2024, a +233% rise, before 2025-26 figures understate due to publication lag. Annual filings moved from 4 in 2017 to a peak of 20 in 2024, with the 2021-2024 span alone showing +233% growth. The 2025 and 2026 totals will rise as later publications land — treat the most recent two years as incomplete, not as a plateau.

Common questions about blower and debris equipment patents
Who holds the most patents in leaf blower and debris handling equipment?
Across the 296 records in this dataset, the leading assignee holds 16 records, with the fifth-ranked company at 12 and the tenth at 7 — a gradual taper rather than one company dominating outright. The top 5 assignees combined account for 23.6% of all 296 records, and the top 10 combined account for 38.2%. That leaves the majority of filings spread across a long tail of the other ranked companies, so a competitive scan needs to look well past the leaders to get a full picture.
Is the blower and debris equipment patent field growing or slowing down?
Filings grew sharply, from 6 in 2021 to 20 in 2024, a +233% increase over that span. The 2025 and 2026 figures currently look lower, but that is expected: publication typically lags filing by about 18 months, so the most recent one to two years of any patent trend are always undercounted at the time they’re pulled. Treat 2024 as the last complete year and expect the 2025-26 counts to rise as more records publish.
What technology areas do leaf blower patents mostly fall into?
The largest IPC subclasses by record share are A47L (cleaning and washing appliances) at 18.2%, E01H (street and track cleaning) at 17.9%, and A01G (horticulture and forestry) at 16.6%, out of 296 records in scope. F04D, the class covering non-positive-displacement pumps and fans, sits lower at 10.8%, suggesting collection and debris-directing mechanisms attract more claim activity than the impeller or fan itself. Because a single record can carry multiple IPC classes, these shares add up to more than 100% of the record total.
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.
Method: Filing trend and technology composition. Derived from a Patsnap search on Blowers and Debris Handling Equipment covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
