Cordless Saws and Cutting Tools Patents: Top Companies & Trends 2026
- Concentrated but not locked up. the top 5 assignees combined hold 786 records, 17.7% of all 4,439 records in scope — leaving a long tail below tenth place at 86.
- Filing has cooled from its 2019 peak. 286 records that year, with the last complete year-over-year window (2021 to 2024) down 39%, from 226 to 138.
- Sawing and surgical classes overlap. B23D sawing/broaching covers 33.3% of records while A61B diagnosis & surgery still touches 17.3%, pointing to shared blade and guard mechanics across tool and medical device filings.
Filing growth compares 2021 (226 records) with 2024 (138) — 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. Top-5 share is the combined record count of the five largest assignees divided by all 4,439 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This dataset tracks patent filings at the intersection of circular saws, reciprocating saws and saw blades with mechanical features such as tooth geometry, cut depth control, kickback protection, dust collection and guard design. The search spans 4,439 published records filed between 2015 and mid-2026, drawn from receiving offices led by the United States, China and the European Patent Office. Publication lags filing by roughly 18 months, so the most recent one to two years in any trend understate real filing activity.
The technology composition mixes conventional woodworking and stone-cutting classes with a notable share of surgical and implant classifications, reflecting how blade guard, cut-depth and kickback-protection mechanics recur in both power tools and surgical cutting instruments. Reading the assignee ranking alongside the IPC breakdown shows where claim space is already dense and where it remains comparatively open.
Filing trend and technology composition
Two views of the same 4,439-record dataset: how filing volume has moved year over year, and how records distribute across IPC subclasses when a record carries more than one class.
Filing trend: a 2019 peak, then a real pullback
Annual filings rose to a peak of 286 records in 2019, then fell across the last complete comparison window: 226 records in 2021 down to 138 in 2024, a 39% decline. Counts for 2025 and 2026 are still incomplete because of publication lag and should not be read as a continued drop.
Technology composition: sawing dominates, surgical classes persist
B23D (planing, broaching & sawing) covers 33.3% of the 4,439 records in scope, with B27B (sawing wood) at 21.0% and B27G (woodworking accessories) at 13.8%. A61B (diagnosis & surgery) still reaches 17.3% and A61F (implants & prostheses) 8.2%, evidence that guard, kickback and cut-depth mechanics claimed for power tools recur in surgical cutting instrument filings.
Shares are the percentage of the 4,439 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Three read-outs from the ranking, the trend line and the IPC breakdown that matter for a filing or freedom-to-operate decision.
Leadership is real but not dominant
The leader holds 205 records and fifth place holds 105, together with the rest of the top 5 accounting for 17.7% of the field. Below tenth place (86 records), the ranking spreads into a long tail of smaller filers, which means the field is not a closed contest even where a few names lead.
Volume has pulled back from its peak
After peaking at 286 records in 2019, annual filings fell from 226 in 2021 to 138 in 2024. Several of the most active named assignees show flat or negative year-over-year momentum in the latest tracked year, though that year is still filling in.
Power tool and surgical claims share mechanics
Guard design, cut-depth control and kickback protection appear across both B-class power tool filings and A61B/A61F surgical and implant filings. A freedom-to-operate review limited to power tool classes alone would miss this adjacent surgical-instrument prior art.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to cordless saws and cutting tools, with the prior art for and against each one.
Who is filing, and where the gate sits
The ranked leaders sit atop a wide field of smaller filers. Momentum among the most visible names has softened in the latest tracked year, and several under-claimed mechanical sub-areas remain open below the surface classes.
A single leader well ahead of fifth place
The top-ranked assignee holds 205 records against 105 for fifth place, a gap that signals sustained investment in blade, guard and dust-collection mechanics rather than a single breakthrough filing.
A long tail below the top ten
Filings taper quickly after the leader group; tenth place holds 86 records, and the ranking includes many single- and low-digit filers, consistent with a field where smaller manufacturers and component specialists still stake individual claims.
Recent-year activity has slowed across named leaders
Several of the most active assignees show a drop to zero or a sharp year-over-year decline in the latest tracked year. This should be read cautiously given publication lag rather than as evidence the field has gone quiet.

The dataset ranks 100 assignees by patent family count, with the leader holding 205 records and fifth place holding 105, together accounting for 17.7% of all 4,439 records in scope. Below tenth place, which holds 86 records, filings spread into a long tail of smaller manufacturers and component specialists. This means leadership is concentrated at the top but far from exclusive, and a new entrant is not necessarily boxed out by a handful of firms.
Filings peaked at 286 records in 2019 and fell in the most recent complete comparison window, from 226 records in 2021 to 138 in 2024, a 39% decline. Figures for 2025 and 2026 look lower still, but that reflects publication lag of roughly 18 months rather than an actual drop in filing activity. Any conclusion about current-year trends should wait for those years to fill in.
Guard design, kickback protection and cut-depth control are mechanical concepts that recur in both power tool blades and surgical cutting instruments, which is why A61B (diagnosis & surgery) reaches 17.3% of the 4,439 records and A61F (implants & prostheses) reaches 8.2%. A record can carry more than one IPC class, so this overlap does not mean the field is split between two unrelated industries — it means the underlying blade and guard mechanics are shared prior art across both. Anyone doing freedom-to-operate work in power tools should not stop at B-class searches alone.
US11273505B2, assigned to Dustless Depot, LLC and published 2022-03-15, claims a circular saw dust collection shroud built around a shroud body and a saw blade hood that engages the saw's upper blade guard. Its distinguishing feature is that the shroud is reconfigurable to mount on either a left- or right-handed circular saw and is adjustable to position the blade hood around the blade as needed. It sits in the dust collection and guard design portion of this landscape rather than in blade geometry or motor/runtime claims.
Based on the technology composition and gate analysis in this dataset, sub-areas such as reconfigurable dust-shroud mounting, blade-hood kickback interlocks, and cross-platform runtime or charge sensing show thinner filing density than the dominant B23D sawing and A61B surgical classes. This does not mean the areas are unclaimed, only that fewer records in this corpus concentrate there. A targeted prior art search on the specific mechanical sub-feature is still necessary before treating any of these as genuinely open.
