Robot Functional Safety Patent Landscape 2026
The robot functional safety patent space is highly concentrated, with the top five filers accounting for seventy percent of the hundred largest filers’ combined output and ABB leading the ranking. The field reached peak annual volume in 2022 and has since plateaued, with a multi-year growth window still positive at twenty-one percent.
ABB and Daifuku anchor a tightly held field
ABB (Switzerland) holds the top position among ranked applicants, followed closely by Daifuku and Universal Robots, each with eighteen patent families. The ranking reveals a narrow leading tier where three applicants are separated by only two families.
The top five filers account for seventy percent of the hundred largest filers’ combined total, indicating strong concentration. A clear tier gap exists between the top three and the remaining applicants, with Kuka at eleven and KEBA AG at eight patent families.

The incumbents’ dominance in manipulator and robot safety — almost entirely within the B25J class — suggests that challengers seeking differentiation must either deepen coverage in adjacent technical branches or target under-served jurisdictions.
Filings from 2024 onward are subject to publication lag and are likely under-counted; the apparent dip in 2025 and zero count for 2026 should not be read as a real decline. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Activity plateaued after a 2022 peak; B25J dominates the technology mix
The annual filing trend and IPC technology composition together show a maturing field that surged through 2022 and now holds near that peak, with robot manipulator safety accounting for the overwhelming share of disclosed inventions.
Annual filing trend
Filings grew steadily from six in 2017 to a peak of twenty-three in 2022, then eased. The 2023 figure of seven and the 2024 figure of twenty-one reflect a plateau rather than a sustained decline; 2025 and 2026 are materially under-counted due to publication lag and should not be treated as real volume.

What the competitive structure means for R&D investment decisions
The combination of high concentration, a maturing lifecycle, active intra-group co-filing, and US/EP jurisdictional dominance shapes both the risks and the entry angles available to new participants.
Field has plateaued near its 2022 peak
The lifecycle stage is Maturity: annual filings have plateaued near their 2022 peak, though the multi-year growth window remains positive at twenty-one percent. Core B25J manipulator safety is well-covered by incumbents, reducing the marginal value of filing in the dominant sub-class. Entrants should prioritize differentiated technical angles or adjacent branches rather than head-on competition in saturated sub-classes.
Lifecycle: MaturityTop five control seventy percent of the largest-filer pool
The top five filers — ABB (Switzerland), Daifuku, Universal Robots, Daifuku Intralogistics America, and Kuka — hold seventy percent of the hundred largest filers’ combined output. This tight tier gap means that a challenger adding a modest portfolio in an under-served branch could move meaningfully in the ranking. The near-tie between ranks two and three (eighteen families each) signals ongoing competitive pressure within the leading tier.
High concentrationDaifuku group co-files heavily within its own corporate family
The most active co-filing pair is Daifuku (Japan) and Daifuku Intralogistics America, with thirteen joint families, reflecting intra-group patent strategy rather than open cross-industry collaboration. A secondary pair — Daifuku and Wynright Corp — accounts for five joint families, consistent with a parent-subsidiary filing structure. No cross-group co-filing activity is evident in the evidence, suggesting the field lacks a broad collaborative ecosystem.
Intra-group co-filingUS and EPO lead; Asia and emerging markets are thin
The United States leads jurisdiction coverage, followed closely by EPO and WIPO PCT. Australia and China each have moderate coverage, while Germany, Austria, Canada, and Japan trail. South Korea, India, Taiwan, and Singapore each show only one record, indicating that safety-critical robot deployments in fast-growing Asian markets are currently under-protected. Building jurisdiction coverage in these markets may offer a low-cost competitive lever.

Co-filing pairs, ranked by the number of jointly-filed patent families.
ABB and Daifuku lead on volume; Universal Robots shows a declining trajectory
The two leading applicants represent distinct strategies: ABB concentrates on programmable manipulator safety while Daifuku spans mobile robot and conveying-system safety. Both show new-entrant momentum signals in the recent period, suggesting recent portfolio build-up.
ABB (Switzerland)
ABB (Switzerland) holds twenty patent families and leads the ranked applicants. Its technology focus is concentrated in B25J 9 (programmed manipulators) with secondary coverage in B25J 13 (control with sensors) and B25J 19 (safety devices for manipulators). Its momentum is flagged as a new entrant in the recent filing window, indicating recent portfolio activity rather than a long-established base.
families: 20Daifuku
Daifuku holds eighteen patent families and is tied for second with Universal Robots. Its portfolio spans B25J 5 (mobile robots), B25J 9 (programmed manipulators), and B65G 67 (conveying and material handling), reflecting a broader operational safety scope than most peers. Like ABB, it shows a new-entrant momentum signal in the recent period. Its intra-group co-filing with Daifuku Intralogistics America and Wynright Corp amplifies its effective portfolio depth.

Machine safety devices and conveying-system safety are under-served relative to the core
Several IPC branches adjacent to the dominant B25J class carry low patent density relative to their technical relevance for robot functional safety deployments; these are observations of relative sparsity and warrant further technical due-diligence before treating them as investment opportunities.
F16P · Machine safety devices
F16P (Machine safety devices) has twenty-three records but accounts for only eight percent of the IPC record base, making it structurally sparse relative to B25J. Physical guarding, interlocks, and mechanical safety stops are integral to robot cell design but are under-patented in the functional safety context. A filer with mechanical engineering depth and existing robot safety expertise could extend coverage here with relatively low filing cost, provided the commercial case for hardware-level safety differentiation is validated.
Search this in Eureka →B65G · Conveying & material handling
B65G (Conveying and material handling) has twenty-two records at seven percent share, yet robots increasingly operate within integrated conveying systems where safety zones overlap between robot and conveyor. Daifuku and Wynright already straddle both classes, but most other applicants do not. An entrant targeting warehouse automation or intralogistics safety — where ISO 3691-4 and similar standards are expanding — could find this a credible adjacent entry point, subject to freedom-to-operate analysis against the Daifuku group portfolio.
