Satellite Internet Constellation Patents: Leaders & Trends 2026
- Filing peaked in 2024 at 549 families, and every tracked assignee's most recent full year is down sharply year-on-year — this field is consolidating claim space, not expanding it.
- H04W and H04B dominate at 1,732 and 1,560 records, while inter-satellite link and spacecraft-specific filings (B64G, 5 records) remain almost untouched relative to the wireless-network layer.
- The most-cited prior art is a mix of 1990s-era satellite internet architecture and 2020s non-terrestrial network handover filings, meaning the citation graph spans two distinct technology generations that any new filing has to clear.
What this landscape covers
This dataset tracks patent families filed against inter-satellite link, handover, user terminal antenna, latency and spectrum coordination claims within satellite internet and non-terrestrial network architectures, filtered to the wireless and spacecraft IPC codes (H04B7, H04W84, B64G1). It spans 2,236 published records filed between 2015 and the July 2026 data cut-off, giving a decade-long view of how claim activity has moved from foundational network architecture toward handover and timing-specific mechanisms.
Filing activity is concentrated overwhelmingly in the wireless communications layer rather than the spacecraft hardware layer: the wireless network and transmission subclasses each carry well over a thousand records, while spacecraft-specific filings under B64G number only five. That split says most of the active patenting is happening in how a terminal talks to a satellite network, not in the satellite platform itself.

Filing trend and technology composition
Two views of the same 2,236-family dataset: how filing volume has moved year over year, and which IPC subclasses carry the claim density.
A decade of filing, now past its peak
Filings started from zero in 2017, built steadily through the early 2020s, passed the midpoint of 359 families in 2022, and peaked at 549 in 2024. The 38 records recorded so far in 2026 look thin against that peak, but the most recent year in any filing trend is always undercounted because publication typically lags filing by around 18 months — the real 2025-2026 filing volume will only become visible in later data pulls.
Wireless layer dominates over spacecraft hardware
H04W (wireless communication networks) and H04B (transmission, general) between them cover almost the entire corpus, with H04L digital transmission a distant third at 320 records. Positioning (G01S), multiplexing (H04J), antennas (H01Q), AI-based computing (G06N) and spacecraft hardware (B64G) each account for under 100 records, marking them as thinly claimed relative to the wireless-network core.
Shares are the percentage of the 2,236 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Configuration for inter-satellite link (US12580641B2, Qualcomm, 2026-03-17)
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may communicate with a non-terrestrial network entity using a radio configuration over a service link. The UE may receive an indication of a topology change event that is to occur in association with an inter-satellite link. The UE may communicate, after the topology change event, using at least part of the radio configuration over the service link. Numerous other aspects are described.Filed by Qualcomm and published March 2026, this claim sits squarely in the inter-satellite link and topology-change space — one of the more recent and narrowly-scoped filings in the corpus.

Three patterns stand out once volume, composition and citation age are read together.
The field has passed its filing peak
Volume rose from zero in 2017 to a peak of 549 families in 2024, roughly 190 above the 2022 midpoint of 359. The sharp drop into 2026 partly reflects publication lag, but the pattern across every tracked assignee's YoY momentum points the same direction: consolidation, not expansion.
Claim density sits in the network layer, not the platform
The wireless communication network and general transmission subclasses account for almost all activity. Spacecraft-specific claims under B64G are nearly absent at five records, which signals open claim space around satellite platform mechanisms rather than a mature, fully-claimed area.
New filings must clear both old and new prior art
The most-cited records include a late-1990s asymmetric satellite-terrestrial internet patent alongside 2020s non-terrestrial network timing-advance and handover filings. A filing strategy that only searches recent non-terrestrial network literature risks missing the older architectural patents still driving citation counts.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to satellite internet constellations, with the prior art for and against each one.
Who is still active, and how much
Every major assignee tracked in the latest-year momentum data is filing less than it did the year before — the question is not who leads, but who is pulling back slowest.
Some assignees have nearly stopped filing
Ericsson's single filing in the latest year against its prior-year volume represents a 93% drop, the steepest of any tracked assignee. Samsung and Google show similarly steep declines at -92% and -87%.
Huawei and Qualcomm hold the smallest declines
Both Huawei and Qualcomm still logged 5 filings in the latest tracked year, and Huawei's -58% YoY drop is the least steep among the six assignees with visible momentum data — still a decline, but a shallower one.
Co-assignee activity is thin and concentrated
Only ten co-assignee pairs appear in the dataset, and one pair — Sony Group and Sony Europe — accounts for 61 joint filings, far ahead of any other pairing. Most other co-filing links show single-digit counts, indicating little cross-company collaboration outside a few corporate-family structures.
| Assignee | Recent year | YoY |
|---|---|---|
| Qualcomm Incorporated | 5 | -91% |
| Huawei Technologies Co., Ltd. | 5 | -58% |
| Nokia Technologies Oy | 3 | -81% |
| Samsung Electronics Co., Ltd. | 2 | -92% |
| Google LLC | 2 | -87% |
| Telefonaktiebolaget LM Ericsson | 1 | -93% |
| Sony Group Corporation | 0 | -100% |
| Sony Europe B.V. | 0 | -100% |
Where to take this next
The dataset points to specific next steps depending on whether the goal is freedom-to-operate, white space filing, or competitive tracking.
Check freedom-to-operate against the most-cited prior art
Before drafting new claims in handover or timing-advance mechanisms, clear the specific most-cited records in this corpus rather than relying on a generic keyword search — several of them predate the current non-terrestrial network terminology.
Run a freedom-to-operate check in EurekaModel the under-claimed branches before a competitor does
B64G spacecraft-hardware claims and AI-assisted spectrum coordination both sit at under 100 records against a corpus of 2,236 — thin enough that a well-drafted first claim could stake out real territory.

Every major assignee's latest-year filings are down sharply YoY. Watching who slows down least is a better competitive signal right now than ranking by cumulative family count.

This dataset tracks 2,236 published patent families filed between 2015 and mid-2026 that match claims around inter-satellite links, handover, user terminal antennas, latency and spectrum coordination within the relevant wireless and spacecraft IPC codes. That figure will keep growing as more recent filings publish, since patent publication typically lags filing by around 18 months. It should be read as a snapshot of a specific claim scope, not a count of every satellite communications patent ever filed.
No — filing volume peaked at 549 families in 2024 after rising from zero in 2017, and every major assignee tracked in the momentum data shows a sharp year-on-year decline in its most recent full year, with drops ranging from roughly 58% to 93%. The 2026 figure looks even lower, but part of that is publication lag rather than a real collapse in activity. Taken together, the pattern points to a field that has passed its peak filing intensity rather than one still accelerating.
Wireless communication networks (H04W) and general transmission (H04B) dominate, together accounting for the large majority of the 2,236 records, with digital information transmission (H04L) a distant third at 320. Positioning, multiplexing, antennas, AI-based computing and spacecraft hardware each sit at under 100 records. That concentration means claim space around how a terminal connects to and hands off between satellites is far more crowded than claim space around the spacecraft platform itself.
The clearest under-claimed branches are spacecraft-specific hardware (B64G, only 5 records), AI-assisted spectrum coordination, and multiplex scheduling across handovers — all thin relative to the heavily-claimed wireless network layer. A first claim in these areas has a better chance of avoiding dense prior art than a new filing in general handover or timing-advance mechanisms, where the most-cited records already set a high bar. Filers should still check the wireless-layer prior art for boundary overlap before assuming clear space.
US12580641B2, filed by Qualcomm and published in March 2026, claims a user equipment configuration for handling a topology-change event associated with an inter-satellite link, including maintaining part of the radio configuration over the service link after the change. It is a narrowly-scoped, recent filing rather than a broad architectural patent, so it is unlikely to block adjacent approaches to inter-satellite link management that do not rely on the same topology-change signalling mechanism. Anyone drafting claims in this specific sub-area should review its exact claim language rather than assume it covers the whole inter-satellite link handover problem.
