Industrial Automation Patents: Top Companies & Filing Trends 2026
- 39.1% concentration. The top five assignees together hold 39.1% of all 23,065 records in scope, with a long tail of single- and few-filing entrants behind them.
- Filings cooled from a 2020 peak. Activity peaked at 1,983 records in 2020 and fell -32% from 1,537 in 2021 to 1,047 in 2024, the last year the data treats as complete.
- Control and data-processing classes dominate. G05B control systems (22.8%) and G06F data processing (20.2%) lead the technology mix, ahead of digital transmission and wireless classes.
Filing growth compares 2021 (1,537 records) with 2024 (1,047) — 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 23,065 records in scope (CR5), not by the ranked leaders only.
What the industrial automation and control patent record shows
Industrial automation and control patenting spans a wide search string on purpose: supervisory control systems, Industrial IoT, digital twins, Manufacturing Execution Systems, functional safety and industrial networks all sit inside the same 23,065-record corpus because they get claimed together in practice. A factory-floor control patent today routinely reaches into wireless networking, AI-based inference and cloud data processing in the same specification, which is why the technology composition below adds up to well over 100% of records.
The filing trend runs from 2017 through a 2026 cut-off, but the last one to two years are always undercounted here: publication lags filing by roughly 18 months, so 2025 and 2026 volumes will keep rising as those applications publish. The reliable read on recent direction is the 2021-to-2024 window, where filings fell -32%, and the assignee ranking, receiving-office split and citation leaders below are drawn from the full record set.
Filing trends and technology composition
Two views of the same 23,065-record corpus: how filing volume has moved year over year, and which IPC subclasses carry the claim density.
A 2020 peak, then a real pullback
Filings rose from 961 in 2017 to a peak of 1,983 in 2020, then declined; the 2021-to-2024 window shows a -32% move from 1,537 to 1,047. Treat 2025 and 2026 figures as still filling in rather than as evidence of a further drop.
Control systems and data processing lead the class mix
G05B (control & regulating systems) and G06F (electric digital data processing) are the two largest classes at 22.8% and 20.2% of records respectively, with H04L digital transmission and H04W wireless networks close behind — evidence that automation claims are now inseparable from networking and data-handling art. G03F photolithography's 10.6% share reflects the semiconductor-equipment assignees active in this search string.
Shares are the percentage of the 23,065 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Three read-throughs from the concentration, class and geography data above.
The top of the field is dense, the rest is open
Nine thousand and fourteen records sit with just five assignees, which means clearance searches in their core claim areas need to start there. Below the top ten (47.1% combined), the ranking thins into single- and few-filing entrants, which is where freedom-to-operate is easier to establish.
Control claims now travel with data-processing claims
The two leading IPC subclasses are control & regulating systems and digital data processing, not a single automation-specific class. A control-system claim filed alone, without the data-processing and networking dependencies, is increasingly the exception rather than the rule.
Volume has pulled back from its 2020 high
The 1,983-record peak in 2020 was not sustained; the 2021-to-2024 window shows a real -32% decline. Because publication lags filing by about 18 months, 2025 and 2026 figures will revise upward and should not yet be read as a continuation of that decline.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to industrial automation & control patent landscape, with the prior art for and against each one.
Leaders, momentum and the gaps between them
The ranked leaders span semiconductor-equipment, industrial-controls and telecom assignees — a mix that reflects how broadly this search string draws automation claims into adjacent art.
A single leader sets the pace
The top-ranked assignee's filing count is more than seven times the fifth-place figure of 485, a gap wide enough that its core claim families are the first stop for any clearance work in this space.
The drop-off past the leader is gradual, not a cliff
From fifth to tenth place the gap narrows to roughly 165 records, suggesting a genuine group of active filers rather than one dominant player and then nothing — useful context when deciding which competitors to monitor beyond the obvious leader.
Recent-year counts are down across the board, but read them cautiously
Every assignee with recent-year momentum data shows a sharp year-over-year drop in the latest year, consistent with the 18-month publication lag rather than a sudden retreat from the field. Treat single-digit latest-year counts as provisional, not as a signal that a competitor has stopped filing.

The dataset points to a few concrete follow-up steps depending on what you are trying to decide.
Map claims against the leading assignee's portfolio
With one assignee holding 3,758 records against a field of 23,065, its specific claim language in control and data-processing classes is the first thing to check before filing in the same space.

One assignee leads with 3,758 records in this corpus, well ahead of the fifth-ranked filer at 485 and the tenth at 321. The top five assignees combined account for 39.1% of all 23,065 records in scope, and the top ten reach 47.1%. Below that concentration, the ranking of 100 companies thins into a long tail of firms with far smaller counts, so competitive monitoring should weight the leader and the next few names most heavily.
Filings rose from 961 in 2017 to a peak of 1,983 in 2020, then declined; over the 2021-to-2024 window, the reliable comparison period, volume fell -32% from 1,537 to 1,047. Figures for 2025 and 2026 look lower still, but that is largely an artefact of publication lagging filing by roughly 18 months rather than a genuine collapse in activity. The honest read is a pullback from a 2020 high, not a field in terminal decline.
Control & regulating systems (IPC class G05B) and electric digital data processing (G06F) are the two largest classes, covering 22.8% and 20.2% of the 23,065 records respectively. Digital information transmission (H04L, 18.9%) and wireless communication networks (H04W, 14.2%) follow closely, showing that modern automation claims routinely bundle control logic with networking and data-handling elements. Photolithography (G03F, 10.6%) also appears, reflecting semiconductor-equipment assignees whose metrology and lithography patents intersect with this search scope.
The clearest gaps sit adjacent to the dominant control and data-processing classes rather than inside them: configuration-fingerprint verification for industrial devices, blockchain-anchored digital twin state records, functional-safety interlocks for wireless sensor meshes, and cross-vendor Manufacturing Execution System interoperability all show thinner, more specific claim coverage. These are branches where the search terms apply but filing volume has not yet concentrated the way it has in core G05B and G06F claims, making them worth a closer freedom-to-operate check before committing to a filing strategy.
US12393180B2, assigned to Rockwell Automation Technologies, Inc. and published 2025-08-19, claims a method for verifying industrial device configurations using blockchain-enabled digital twins. Specifically, it covers comparing a configuration fingerprint of an industrial automation component against a second fingerprint taken at a later time to determine equivalency. Anyone building configuration-verification or drift-detection tooling for industrial devices should read the granted claims closely, since the fingerprint-comparison mechanism is the operative limitation to design around.
