Jaw and Gyratory Crusher Patents: Leaders & Filing Trends 2026
- Concentrated at the top. the five most active filers together hold 54.4% of all 676 records in scope, and the top ten hold 65.8%.
- Filing kept climbing through 2024. activity rose from 15 filings in 2021 to 23 in 2024, a 53% increase over that span, before the two most recent years understate true volume due to publication lag.
- Almost everything sits in one class. 87.4% of records carry a B02C crushing/grinding/pulverising classification, with smaller but real footprints in animal feed, flotation and material testing.
Filing growth compares 2021 (15 records) with 2024 (23) — 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 676 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This dataset tracks 676 published records filed between 2015 and mid-2026 that combine core jaw and gyratory crusher mechanics — nip angle, liner wear profile, spider bearing, closed side setting, toggle mechanism — with the machine terms themselves. It is a mechanical-design corpus, not a materials-science one: the claims at stake are largely about how the crushing chamber is actuated, how the movable jaw or mantle is positioned, and how wear is managed over a service life, rather than about the metallurgy of the wear parts.
The record set spans 100 ranked assignees, receiving offices led by the United States, Australia and the EPO, and a filing trend that peaked so far in 2023. Because publication typically lags filing by around 18 months, the 2025 and 2026 figures in any trend chart are still filling in and should not be read as a slowdown.
Filing trend and technology composition
Two views of the same 676 records: how filing volume has moved year over year, and which IPC subclasses the claims actually sit in.
Filing trend, 2017-2026
Filings rose from 10 in 2017 to a peak of 39 in 2023, with the 2021-to-2024 span alone showing a 53% increase (15 to 23). The final two years in the chart are partial because of publication lag and should not be read as a decline.
Technology composition by IPC subclass
B02C (crushing, grinding and pulverising) covers 87.4% of the 676 records, confirming this is overwhelmingly a core-mechanism corpus. The next largest classes are animal feed (A23K, 3.0%), food and beverage processing (A23L, 2.5%) and dimensional measurement (G01B, 2.5%) — evidence of crusher IP reaching into feed processing and in-chamber sizing measurement, not just the base machine.
Shares are the percentage of the 676 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Method and system for controlling a jaw crusher (US20160250642A1)
A jaw crusher control system positions a movable jaw against a stationary jaw using a hydraulic positioning device, driven by a signal from a crushing chamber level detector. The system computes a first closed side setting when the chamber is judged full of material, and a second closed side setting when the chamber is judged empty, letting the machine adjust its gap dynamically rather than run a fixed setting.Filed by Sandvik Intellectual Property AB, 2016-09-01.

Three read-throughs from the concentration, trend and classification data above.
The core mechanism is claimed densely at the top
With just five assignees holding more than half of all 676 records, the base jaw and gyratory crusher mechanism — toggle actuation, CSS control, liner retention — is occupied ground. New entrants filing on the base machine geometry are filing into dense prior art held by a small group.
Growth held up through the last complete filing year
Filing volume rose from 15 in 2021 to 23 in 2024, and the field's peak year so far is 2023 at 39. That is sustained interest in the mechanism, not a technology in decline — the apparent drop-off after 2024 is a publication-lag artefact, not a real one.
This is a core-mechanism corpus with feed-processing spillover
The overwhelming majority of records sit in B02C (crushing, grinding, pulverising), but smaller footprints in animal feed (A23K), food processing (A23L) and in-chamber measurement (G01B) show the same crusher claims reaching into adjacent processing and sensing applications.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to jaw and gyratory crusher design, with the prior art for and against each one.

Ten identified co-assignee pairs in this dataset, with the strongest links all centred on Sandvik-affiliated inventor teams — a sign of a stable in-house engineering group rather than cross-company joint filing.
Who is filing, and where the gaps sit
A ranked field of 100 assignees, with activity concentrated among a handful of established crusher OEMs and a long tail of single- or few-filing entrants.
One filer holds a clear lead
The leading assignee's 154 records sit well ahead of the field's fifth-place figure of 22 and tenth-place figure of 12 — a steep drop-off rather than a gradual one, typical of a mechanism space anchored by a dominant OEM.
Recent-year counts read low across the board
Every assignee tracked for recent-year momentum, including the field leader, shows zero filings in the latest year on record. Given the roughly 18-month publication lag, this reflects incomplete data for 2025-2026 rather than a genuine stop in filing activity by any of these companies.
Filing follows mining geography
The United States, Australia and the EPO lead receiving offices, with Canada, WIPO/PCT and India also represented in meaningful volume — a pattern consistent with where crushing equipment is manufactured and where mining and aggregates operations are concentrated.

One assignee leads clearly, with 154 of the 676 records in this dataset, well ahead of the fifth-place figure of 22 and tenth-place figure of 12. The top five assignees combined hold 54.4% of all records, and the top ten hold 65.8%, so the base mechanism — toggle actuation, closed side setting control, liner retention — is claimed densely by a small group of established crusher OEMs. Anyone designing around the core machine geometry should expect to run into this group's prior art first.
Filing grew over the last complete comparison window, rising from 15 filings in 2021 to 23 in 2024, a 53% increase. The single busiest year so far is 2023, with 39 filings. The 2025 and 2026 figures look lower only because publication lags filing by roughly 18 months — they will revise upward as more filings publish, so they should not be read as an actual slowdown.
The large majority of records, 87.4% of all 676, carry a B02C classification for crushing, grinding and pulverising equipment — this is fundamentally a core-mechanism corpus. Smaller but consistent footprints appear in animal feed processing (3.0%), food and beverage processing (2.5%), and dimensional measurement (2.5%), showing that some crusher claims extend into feed sizing and in-chamber sensing applications rather than staying purely mechanical.
This Sandvik filing covers a jaw crusher control system that uses a crushing chamber level detector to drive a hydraulic positioning device, switching between a first closed side setting when the chamber reads full and a second when it reads empty. It blocks control schemes that tie hydraulic jaw positioning directly to a chamber-fullness signal in this two-state way. Designs that use a different sensing input, a continuously variable setting rather than two discrete states, or manual/non-hydraulic actuation sit outside its core claim language, though a freedom-to-operate check against the full claim set is the only way to confirm this for a specific design.
The classification data points to a few under-claimed branches relative to the dense core-mechanism filing: in-chamber feed size sensing, liner wear profile monitoring, and flotation-integrated crushing circuits all show up in the IPC composition but with far lower record counts than the base B02C mechanism claims. These are areas with documented market and processing relevance but thinner patent coverage, making them worth a targeted prior-art check before assuming they are already occupied.
