Avionics Partitioning & ARINC 653 Patents: Top Companies 2026
- 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 grew +156% from 2021 to 2024 (9 to 23 records), the fastest sustained run in the coverage window, before the expected 18-month publication lag thins out 2025-2026.
- G06F carries 73.8% of records while G10L (speech/audio, 6.3%) and G01S (radar/positioning, 5.2%) stay thin — signal that core partitioning logic is claimed hard, adjacent sensor integration is not.
Filing growth compares 2021 (9 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 286 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
ARINC 653 defines how a single core processing module hosts multiple software partitions with guaranteed time and memory separation, so a fault in one partition cannot starve or corrupt another. The claims in this dataset cluster around partition scheduling, health monitoring, configuration tables, and the mechanics of running several avionics functions safely on shared hardware. This is the patent layer beneath integrated modular avionics (IMA): the architecture that let airframers move from federated, one-box-per-function designs to consolidated computing platforms.
Coverage runs from 2015 through the 2026-07-31 cut-off, with 286 published records pulled from a search string anchored on ARINC 653, time/space partitioning, and the specific mechanisms — time partitioning, memory partitioning, health monitor, configuration table, core processing module, partition scheduling — that examiners and drafters use to describe the standard in claim language.
Filing trend and technology mix
Two views of the same 286 records: how filing activity moved year over year, and which IPC subclasses the claims actually sit in.
A decade of uneven but rising activity
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.
Digital processing dominates, sensor and speech classes stay thin
G06F (electric digital data processing) appears in 73.8% of the 286 records, confirming that most claims describe the partitioning and scheduling logic itself rather than any particular sensor or physical subsystem. H04L (23.4%) and G08G (12.2%) show the next-heaviest overlap, tied to networked avionics and traffic-control integration; G10L and G01S sit well below 10%, marking where claim density has not yet caught up with where avionics platforms are heading.
Shares are the percentage of the 286 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Configuration tooling for ARINC 653 compliance
A representative filing from Electronics and Telecommunications Research Institute describes apparatus for configuring an aeronautical system to comply with the ARINC 653 standard: a display unit for capturing setting information through a user interface, an intermediate-model generation unit, an XML conversion unit, and a translator that turns the resulting XML document into source code for the target platform.Filed 2013-10-17. Illustrates how configuration-table tooling — rather than the scheduling kernel itself — has become its own claimable layer around the ARINC 653 standard.

Three read-throughs from the concentration, citation and co-filing patterns in this dataset.
Five incumbents hold most of the claim space
With 180 of 286 records held by five assignees, a new entrant's freedom-to-operate review can be scoped tightly rather than run against the full 42-company ranking. The long tail below tenth place (7 records) is thin and fragmented.
Foundational IMA architecture claims still anchor citation counts
The most-cited record, on communication handling in integrated modular avionics, sits well ahead of the next tier. High citation counts here reflect age and foundational scope more than present-day commercial weight.
Inventor teams repeat across filings, assignees rarely co-file
The strongest linked pairs — Danielsson Torkel with Pettersson Anders, Hakegard Jan, and Gripsborn Anders — point to a stable inventor group filing repeatedly for the same organisation, not cross-company joint filing.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to avionics partitioning and arinc 653 platforms, with the prior art for and against each one.
| Assignee | Co-assignee | Shared families |
|---|---|---|
| DANIELSSON TORKEL | PETTERSSON ANDERS | 11 |
| DANIELSSON TORKEL | HAKEGARD JAN | 11 |
| DANIELSSON TORKEL | GRIPSBORN ANDERS | 8 |
| HAKEGARD JAN | GRIPSBORN ANDERS | 8 |

The ten identified co-assignee pairs cluster around a small number of repeat inventor names, consistent with concentrated in-house filing programmes rather than joint ventures.
Who is filing, and where the gaps sit
The ranked leaders account for 80.8% of the 286 records between them; recent-year momentum has flattened across the named leaders even as the field grew overall.
One filer sits well ahead of the field
The top assignee's 68 records is more than triple the fifth-place count of 18, a gap wide enough that a single company's litigation and licensing posture can move the whole competitive picture.
A tight mid-tier before the tail thins out
Positions five through ten cluster between 18 and 7 records, evidence of several airframers and avionics suppliers maintaining active but not dominant filing programmes in parallel.
Recent-year filing has gone quiet among the top names
Every one of the leading assignees shows zero recorded filings in the latest year, including a -100% year-on-year move for one. Given the ~18-month publication lag, this reads as a data gap to watch rather than a real retreat.

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.
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.
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.
The IPC composition shows a heavy skew toward G06F (electric digital data processing, 73.8% of records) with much thinner coverage in G10L (speech and audio, 6.3%) and G01S (radar, sonar and positioning, 6.2%… 5.2%). That gap suggests the core scheduling and partitioning logic is well claimed, while integrating speech interfaces, radar data or positioning systems into a partitioned avionics core is comparatively open. A first claim there would tie a specific sensor-data path to a partition's time or memory budget rather than restate the general scheduling mechanism.
Not necessarily. The most-cited record in this dataset, on communication handling in integrated modular avionics, has 171 citations, but citation counts inside a searched corpus tend to favour older filings simply because they have had more time to be cited. High citation counts are a better signal of a document's foundational influence on how the field describes itself than of which claims are commercially active today. Current relevance needs to be checked against filing date, family status and prosecution history separately.
