Patent Landscape · Telecom & WirelessNon-Terrestrial Network RF Front-End Patents
- Filing has already peaked. 2024 recorded 1,668 filings, the high point of the series, but every tracked assignee shows double-digit to near-90% year-on-year declines into the most recent year — a maturing claim map, not a growing one.
- Lenovo's three entities dominate recent volume. Its Beijing, Singapore and US filing arms each outpace other named assignees in the latest year, even as all three pull back sharply from prior filing rates.
- Wireless-network and transmission claims crowd out RF hardware. H04W and H04B together account for far more records than H01Q antennas or H01P waveguide/microwave elements, meaning the RF front-end hardware itself is comparatively less claimed than the network protocols wrapped around it.

Filing growth compares 2021 (685 records) with 2024 (1,668) — 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 12,688 records in scope (CR5), not by the ranked leaders only.

Overview
What this landscape covers
This dataset tracks patent families at the intersection of non-terrestrial network (NTN) systems and RF front-end hardware — the amplifiers, transceivers and antenna elements that let a terrestrial device talk to a satellite. The search spans filings from 2015 through the 2026-07-31 data cut-off, drawing on 12,688 published records and receiving-office filings concentrated in the United States, WIPO/PCT, and Europe. Publication lags filing by roughly 18 months, so the 2026 count in the trend chart understates actual filing activity for that year.
The technology composition skews toward network and transmission claims rather than discrete RF hardware: H04W (wireless communication networks) and H04B (transmission, general) each cover thousands of records, while H01Q (antennas) and H01P (waveguides and microwave elements) — the parts most directly tied to physical RF front-end design — cover a much smaller share. That split matters for anyone trying to place a hardware-specific claim: the crowded ground is protocol and system-level, not always the antenna or amplifier itself.

The Numbers
Filing trends and technology composition
Two views of the same 12,688-family corpus: how filing volume has moved year over year, and which IPC subclasses carry the claim density.
A peak already behind us
Filings rose from 628 in 2017 to a peak of 1,668 in 2024, with 2022 sitting at 858 roughly at the midpoint of that climb. The 2026 figure of 356 is a partial year and will rise as later publications land, but the assignee-level momentum data — uniformly negative year-on-year — points to a genuine slowdown rather than a reporting artefact alone.
Network protocol claims outweigh RF hardware claims
H04W (6,102 records) and H04B (5,092) dominate the composition, followed by H04L (3,182) for digital transmission. H01Q antennas (1,421) and H01P waveguide/microwave elements (718) — the classifications closest to physical RF front-end design — are present but comparatively thin, alongside smaller pockets in G01S positioning (580), G06F data processing (396) and H04N video (287).
Shares are the percentage of the 12,688 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Representative filing and most-cited records
Representative Record
Vehicular communication unit with integrated access and backhaul relay
MOLEX, LLC
Exemplary examples are disclosed of vehicular communication systems comprising communication units including integrated access backhaul (IAB) vehicular mounted relay (VMR) modules. In exemplary examples, the communication unit is configured for providing wireless connectivity with a terrestrial network (TN) and a non-terrestrial network (NTN) outside the vehicle. The communication unit is also configured to provide wireless connectivity to a telecommunication control unit (TCU) and user equipment (UE) inside the vehicle.Filed by MOLEX, LLC and published 2025-06-05, this record sits at the practical edge of the corpus: it claims dual TN/NTN connectivity from inside a moving vehicle, bridging cabin user equipment to both networks through a single relay module.

What the data implies for filing strategy
Three patterns stand out once filing counts are read alongside the technology split and receiving-office mix.
Filing Momentum
1,668 → 356
peak year to latest partial year
The corpus has moved past its filing peak
2024's 1,668 filings mark the high point of a decade-long climb from 628 in 2017. Every recent-year momentum figure tracked for named assignees is negative, several by more than 70%, which is a stronger signal than the partial 2026 count alone.
Read alongside the 18-month publication lag before concluding the field is shrinking outright.
Technology Split
H04W 6,102 vs H01Q 1,421
network claims vs antenna claims
Hardware claim space is thinner than network claim space
Wireless network and transmission subclasses carry roughly four times the record count of antenna claims, and more than eight times that of waveguide and microwave element claims. That gap suggests physical RF front-end design is less contested ground than the protocols that sit above it.
A useful filter when deciding whether a claim competes on hardware or on system architecture.
Filing Geography
US 5,031 · PCT 2,846
leading receiving offices
US and PCT filings anchor the corpus
The United States receives the largest single share of filings, with WIPO/PCT and the European Patent Office next. India, Canada and Australia each carry a meaningful but smaller share, indicating where secondary filing strategies concentrate.
Receiving-office counts reflect filing strategy, not market size alone.
Collaboration
10 co-assignee pairs
strongest pairing: 80 shared families
Collaboration is concentrated, not broad
Only ten co-assignee pairings appear in the dataset, and the strongest pairing is built around one organisation working repeatedly with the same named inventors. This points to a small number of tightly coupled filing programmes rather than a broad web of cross-company collaboration.
Useful for identifying which inventor teams to watch inside a given assignee.

Players
Who is filing, and where they are pulling back
Recent-year momentum is uniformly negative across every named assignee tracked, but the scale of decline varies — and the ranking of who still files the most has not changed even as volumes fall.
Lenovo Group
117 filings, -65% YoY
latest-year filings, Beijing entity
Lenovo's three filing entities still lead recent volume
Lenovo's Beijing, Singapore and US entities each post the highest latest-year filing counts among named assignees, even though each is down sharply from the prior year — the Singapore entity fell 76% and the US entity 73%. The group's overall footprint remains the largest in the dataset despite the pullback.
Watch whether the decline continues or whether 2026's partial-year reporting is masking a rebound.
Ofinno LLC
26 filings, -76% YoY
latest-year filings
Ofinno anchors the strongest co-assignee pairings
Ofinno LLC appears in all three of the strongest co-assignee pairings in the dataset, each built around a named inventor rather than a second corporate assignee. That pattern suggests a small, stable inventor team driving a large share of the entity's output.
A useful signal for tracking which individual inventors carry the most weight inside a filing programme.
Qualcomm & InterDigital
13 and 11 filings, -77% and -87% YoY
latest-year filings
Established chipset and standards players are filing less, not more
Qualcomm and InterDigital both show among the steepest year-on-year declines in the momentum table, despite being longstanding names in RF and cellular standards patenting. Their reduced latest-year counts are consistent with the corpus-wide slowdown rather than a company-specific retreat.
Cross-check against standards-essential filing cycles before reading this as disengagement from NTN.

FAQ
Common questions on NTN RF front-end patents
In this landscape it means a patent family whose claims combine non-terrestrial network (NTN) or satellite communication elements with RF front-end hardware terms such as low-noise amplifiers, RF front-end modules, or satellite transceivers. The search deliberately pairs a network-side term with a hardware-side term so that pure protocol patents without any RF hardware claim, and pure RF hardware patents with no satellite or NTN context, are both excluded. The result is a corpus of 12,688 patent families sitting specifically at that intersection.
Lenovo's Beijing, Singapore and US entities post the highest latest-year filing counts among named assignees in this dataset, with Ofinno LLC, Qualcomm and InterDigital also active. All of these entities show negative year-on-year momentum in the most recent year, so leadership by volume does not currently mean leadership by growth. Ofinno LLC in particular stands out for its co-assignee pairings with individual named inventors rather than corporate partners.
No — filing peaked at 1,668 in 2024, up from 628 in 2017, but every tracked assignee shows a year-on-year decline into the latest year, several exceeding 70%. The 2026 figure of 356 is a partial year and will rise somewhat as later publications are indexed, since publication typically lags filing by around 18 months. Even accounting for that lag, the consistency of the decline across assignees points to a genuine slowdown rather than a reporting gap alone.
The technology composition shows H04W and H04B network and transmission claims far outnumbering H01Q antenna and H01P waveguide/microwave claims, meaning the physical RF hardware side of the field carries comparatively less claim density than the protocol layer above it. Sub-areas such as multi-band low-noise amplifier switching for NTN-to-terrestrial handover, waveguide-integrated phased-array feed elements, and Doppler pre-compensation circuits in satellite transceivers show thinner coverage relative to the network-layer crowd. That does not guarantee an easy filing, but it does mean fewer competing claims to design around in those specific areas.
Citation counts inside a searched corpus favour older records simply because they have had more years to accumulate citations, regardless of subject-matter centrality. Some of the most-cited records here reflect broad foundational filings in broadcast and communications systems rather than NTN-specific RF front-end design. Treat the citation ranking as a signal of general influence within the citation graph, not as a ranking of current technical relevance to satellite RF hardware.
