Digital Beamforming Payload Patents: Who Leads, Where the Gaps Are 2026
- Concentrated at the top. Five assignees hold 65.6% of the 285 records in scope, and the leader alone accounts for 98 — this is a field with an entrenched core, not an open field.
- Filing has cooled since 2017. The peak year was 2017 at 55 records, and complete-year data shows a -59% drop from 17 records in 2021 to 7 in 2024.
- Antennas and multiplexing trail transmission claims. H04B transmission claims sit on 80.4% of records, while H01Q antenna claims (27.4%) and H04J multiplex claims (9.5%) leave more room to differentiate.
Filing growth compares 2021 (17 records) with 2024 (7) — 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 285 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This landscape covers patent filings at the intersection of onboard digital payload processing and beamforming control for satellite communications — channelizers, polyphase filter banks, beam hopping, downlink power allocation and radiation-hardened processing hardware. The scope spans 285 published records with priority or publication activity from 2015 through the 2026 data cut-off.
Filing activity peaked in 2017 and has since declined through the last complete reporting year, though publication lag of roughly 18 months means the final one to two years in the dataset will still fill in as later filings publish.
Filing trends and technology composition
285 records in scope, spanning receiving offices led by the United States and Europe, with technology composition weighted heavily toward general transmission claims.
A 2017 peak followed by a sustained pullback
Filings ran from 55 in 2017 down to 7 by 2024 (-59% from the 2021 figure of 17), with 2025 and 2026 figures still incomplete due to publication lag.
Transmission claims dominate; antennas and multiplexing trail
H04B (transmission, general) appears on 80.4% of the 285 records, far ahead of H01Q antennas at 27.4%, H04J multiplex communication and H03H impedance networks/filters each near 9%, and H04L digital transmission also near 9% — classes overlap because records carry multiple IPC codes.
Shares are the percentage of the 285 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

US10230407B2 — Radio receiver with hybrid channelizer architecture
A receiver architecture that frequency-shifts an incoming radiofrequency signal and routes the original and shifted signals through two polyphase filter banks, each producing filter bank outputs for separate sets of sub-bands, combining the outputs into a hybrid channelizer.Filed by Hughes Network Systems, LLC; published 2019-03-12.

Three patterns stand out once the raw counts are read against each other: where claim density sits, how fast the field is still moving, and which citation anchors still shape freedom-to-operate analysis.
A small group holds most of the claim space
Five assignees account for 65.6% of all 285 records in scope, with the leader alone holding 98 records. A new entrant filing broad transmission or channelizer claims is filing directly into occupied ground.
Filing has slowed from its 2017 peak
Complete-year data shows filings fell from 17 in 2021 to 7 in 2024, a -59% change, after peaking at 55 in 2017. This reads as a maturing claim landscape rather than declining interest, since recent years remain understated by publication lag.
Transmission claims crowd the core; antennas and filters are lighter
H04B (general transmission) sits on 80.4% of the 285 records, well ahead of H01Q antennas (27.4%) and H04J multiplex communication (9.5%). The gap suggests more room to differentiate on antenna-integration and multiplexing claims than on core transmission architecture.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to digital beamforming and payload processors, with the prior art for and against each one.
Who holds the ground, and who is still moving
The ranked leaders span satellite operators, prime contractors and payload specialists. Momentum in the most recent year is thin across the board, consistent with a field where the largest holders are defending established positions rather than expanding them.
A single dominant filer
The top-ranked assignee holds 98 of the 285 records in scope, more than three times the fifth-place holder's 14. This is the party any freedom-to-operate check in beamforming or channelizer claims should start with.
A long tail below the top ten
The assignee ranking covers 34 companies across all 285 records, but the top ten alone already account for 82.8% of filings. Everything below that line is thin, single-digit activity rather than an active second tier.
Momentum has gone quiet across the leaders
Recent-year momentum by assignee shows most of the top holders at zero filings in the latest year, with the single most active leader recording just one. Read this cautiously: publication lag means the last one to two years understate true filing activity for everyone.

Where to take this analysis
The dataset points to a field with a dominant early filer, a cooling but not dead filing trend, and specific IPC branches that remain lighter than the core. The next steps depend on whether the goal is freedom-to-operate, whitespace filing, or tracking a specific competitor.
Run a freedom-to-operate check against the leader
With one assignee holding 98 of 285 records, any new beamforming or channelizer filing should be checked against that portfolio first, not the field average.

One assignee leads with 98 of the 285 records in scope, well ahead of the fifth-place holder at 14 and tenth place at 8. The top five combined hold 65.6% of all records, and the top ten hold 82.8%, so the field is concentrated rather than fragmented. Any competitive or freedom-to-operate analysis in this space should start by reviewing that leading portfolio in detail rather than treating the field as evenly distributed.
Filing peaked in 2017 at 55 records and has declined since, with complete-year data showing a drop from 17 records in 2021 to 7 in 2024, a -59% change. That said, publication typically lags filing by around 18 months, so the 2025 and 2026 figures in any dataset will understate true activity and should not be read as a further decline yet. The honest read is a maturing claim landscape following a strong early-2020s filing wave, not a field going cold.
H04B, the general transmission subclass, appears on 80.4% of the 285 records in scope, making it the dominant classification by a wide margin. H01Q antennas follow at 27.4%, with H04J multiplex communication, H03H impedance networks and filters, and H04L digital information transmission each sitting near 9%. Because records often carry multiple IPC codes, these shares add up to more than 100% and should be read as overlapping claim coverage, not mutually exclusive categories.
US10230407B2, assigned to Hughes Network Systems and published in 2019, covers a hybrid channelizer receiver architecture that frequency-shifts an incoming signal and processes both the original and shifted signals through separate polyphase filter banks before combining their outputs. Anyone designing a receiver that splits a wideband signal into sub-bands using dual polyphase filter banks with a frequency-shifting stage should review this claim set closely. It does not block channelizer designs built on materially different filtering or combining architectures, so the practical question is how close a new design's filter bank structure sits to this specific hybrid arrangement.
The clearest gaps sit in branches with lower filing density than the dominant H04B transmission core: beam-hopping schedule optimisation, radiation-hardened FPGA reconfiguration, digital transparent processor interference mitigation, and dynamic downlink power allocation across coverage areas. These are not empty spaces, but they carry materially fewer claims than core transmission and antenna architecture, which is where 80.4% and 27.4% of records respectively sit. A first claim in one of these branches would do well to combine a specific hardware implementation detail with a defined operational trigger, rather than claiming the general concept broadly.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
