Active Filers Ranked
Filing growth compares 2021 (2 records) with 2024 (54) — 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.

Overview
What this landscape covers
This review covers 113 published records filed against child restraint system crash performance between 2015 and the 2026-07-31 cut-off, matched on head excursion, chest deflection, side impact protection, dummy instrumentation, regulation updates and misuse rate. The corpus is small enough that individual assignees move the picture: a single leader accounts for a large share of the ranked filers, and the filing curve shows a sharp, recent acceleration rather than a steady build-up over the full decade.
Because publication lags filing by roughly 18 months, the 2025 and 2026 figures in the trend line are still filling in and should not be read as a slowdown. 2024, the peak year recorded so far, is the most recent year that can be treated as complete.

The Data
Filing trend and technology composition
The counts below use the same 113-record denominator throughout; a record can carry more than one IPC subclass, so composition shares add up to over 100%.
A three-year filing surge, not a steady climb
Filings sat near zero through the mid-2010s, then rose from 2 records in 2021 to 54 in 2024 -- a +2600% increase over that span. That is the sharpest slope in the dataset's coverage window, and it concentrates almost entirely in the last three complete filing years rather than building gradually since 2015.
B60N dominates; adjacent classes are thin
B60N (vehicle seats and interior) appears on 97.3% of the 113 records, confirming that crash-performance claims are filed overwhelmingly as seat-structure inventions. B60R, B60J, B60Q, E05F, G01F, G01G and G01S each sit at 17.7% or below, meaning the sensing, measurement and signalling angles around the seat are far less contested.
Shares are the percentage of the 113 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Representative filing and most-cited prior art
Representative Record
Child restraint system including internal side impact surfaces (US20250042313A1)
GRACO CHILDREN'S PRODUCTS INC.
The filing describes a child restraint seat with a headrest and two sidewalls, each carrying an internal side impact surface. A pocket forms between each surface and its sidewall so that, in a side-impact event, a child's arm or elbow falls into the pocket while the impact surface manages the load path around it. The application describes four such surfaces as one configuration.Filed by Graco Children's Products Inc., published 2025-02-06.

What the numbers mean for a filing decision
Three patterns stand out once the ranking, the trend and the classification data are read together.
Filing Velocity
+2600%
2021 to 2024
The field moved fast in a narrow window
Filing volume was negligible through the mid-2010s and then rose from 2 records in 2021 to 54 in 2024. That kind of acceleration usually means a regulatory trigger or a competitive response rather than organic technology maturation, and it means prior art searches anchored only on older years will miss most of the active claim space.
Trend data, 2015-2024
Claim Concentration
64 vs 6
leader vs fifth place
One assignee holds a disproportionate share
Among the 20 companies in the ranked list, the leader's count of 64 records dwarfs the fifth-place count of 6 and the tenth-place count of 3. A design-around strategy has to start with that leader's claim set specifically, not with an average of the field.
Assignee ranking, 20 companies
Classification Skew
97.3%
of 113 records carry B60N
Seat-structure claims crowd out sensing angles
With B60N present on 97.3% of records and every other subclass at 17.7% or lower, most inventive effort has gone into the seat and restraint structure itself. Sensor fusion, positioning (G01S) and flow/level measurement (G01F) branches sit at 5.3% each, a much shallower claim density.

Players
Who is filing, and where the gate stands
The ranked list covers the 20 companies the data endpoint returns for this search; it is not a top-100 or top-50 cut, so treat it as the whole visible field rather than a sample.
Leader
64
records
A single assignee sets the pace
The top-ranked filer's count of 64 records is far ahead of the rest of the ranked list, and its co-assignee pairs with individual inventor-assignees are the strongest links recorded in this dataset, suggesting concentrated in-house R&D rather than a joint-venture filing pattern.
Assignee ranking
Momentum
0 in latest year
for several leaders
Recent-year activity has gone quiet across the board
Every assignee tracked for year-over-year momentum, including the leader, shows zero records in the latest year, with the leader itself down -100% YoY. Given the 18-month publication lag, this reads as a reporting gap rather than a genuine pullback, but it means recent competitive moves are not yet visible in the public record.

Receiving Offices
US 25 / PCT 25
leading offices
Filing is split evenly between the US and PCT route
The United States and WIPO's PCT channel each show 25 filings, with Europe, Australia, Canada and Singapore trailing behind. That pattern points to applicants seeking broad optionality before committing to national phase, consistent with a field still settling on which markets matter most.

Where to take this next
The landscape points to a narrow, fast-moving field with one dominant filer and several thin adjacent branches.

The jump from 2 to 54 records between 2021 and 2024 likely traces to a small number of inventor teams; identifying them early flags who is setting near-term claim boundaries.

FAQ
Common questions on this landscape
One assignee leads the ranked list with 64 records, well ahead of the fifth-place company at 6 and the tenth-place company at 3. This is a concentrated field rather than an evenly split one, so a competitive read has to weight that leader's filings heavily rather than treating the ranking as a flat list. The remaining 19 ranked companies form a long tail, several with only a handful of records each.
Filings rose from 2 records in 2021 to 54 in 2024, a +2600% increase over that three-year span, after sitting near zero through most of the earlier years in scope. 2024 is the most recent year that can be treated as complete, since publication typically lags filing by around 18 months. Readers should not interpret the lower counts in 2025 and 2026 as a slowdown; those years are still filling in.
B60N, the vehicle seats and interior subclass, appears on 97.3% of the 113 records in this dataset, confirming that most inventive activity is filed as seat-structure claims. Other subclasses -- B60R, B60J, B60Q, E05F, G01F, G01G and G01S -- each sit at 17.7% or below, meaning sensing, measurement and signalling functions around the seat carry much lighter claim density. That gap is where adjacent filing opportunity tends to sit.
US20250042313A1, filed by Graco Children's Products Inc. and published 2025-02-06, describes a child restraint seat with internal side impact surfaces at each sidewall and a pocket formed between each surface and the sidewall, so a child's arm falls into the pocket during a side-impact event rather than absorbing the full load. The application also describes a four-surface configuration. It sits squarely in the dominant B60N seat-structure branch of this landscape, so anyone designing side-impact geometry in that class should review its claim scope directly rather than relying on the abstract alone.
The clearest gaps sit outside the crowded B60N seat-structure core, in subclasses like G01S (radar-based positioning), G01F (flow-based measurement) and G01G (weighing/misuse sensing), each present on only 5.3% of the 113 records. These branches touch on occupant sensing and misuse detection rather than the physical seat structure itself, and their low filing density suggests room for narrowly drafted claims that would not read directly on the dominant leader's portfolio.
