Avionics Partitioning & ARINC 653 Patents: Top Companies 2026
Avionics Partitioning and ARINC 653 Platform Patents
62.9% of all 286 records sit with just five assignees, so freedom-to-operate work in this field starts with a short list of incumbents, not a broad search. Filings moved from 2 records in 2017 to a peak of 23 in 2022, with the three-year run from 2021 (9) to 2024 (23) marking the fastest growth in the window — a +156% increase. 2025 and 2026 read low, but that reflects the roughly 18-month gap between filing and publication rather than a real slowdown.

Common questions on this landscape
What is ARINC 653 and why does it matter for patents?
ARINC 653 is the avionics standard that defines time and space partitioning on a shared computing module, letting multiple safety-critical software functions run on one processor without interfering with each other. It matters for patents because the standard itself is not proprietary, but the specific mechanisms used to implement it — partition scheduling algorithms, health monitoring logic, configuration-table generation, multi-core safety extensions — are exactly what gets claimed. This dataset of 286 records is built around those implementation mechanisms rather than the standard document itself.
Who holds the most patents in avionics partitioning?
The ranking covers 42 companies, and it is heavily front-loaded: the leading assignee holds 68 records, more than triple the count at fifth place (18). The top five assignees together account for 62.9% of all 286 records in scope, so most competitive analysis can focus on a small group rather than the full ranked list. Below tenth place (7 records) the field thins into a long tail of smaller filers.
Is the avionics partitioning patent field still growing?
Yes, based on the years that have had time to fully publish. Filings rose from 9 in 2021 to 23 in 2024, a +156% increase, with 2022 as the peak year so far at 23 records. Figures for 2025 and 2026 look lower, but that is expected: publication typically lags filing by around 18 months, so the most recent one to two years always understate true filing activity.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Avionics Partitioning and ARINC 653 Platforms covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
