Telecom & Next-Gen Network Patents: Who Leads, Where Gaps Are 2026
- Concentrated but not locked down. The top 5 assignees hold 36.6% of all 358,262 records in scope, and the top 10 hold 44.3% — meaningful concentration, but well over half the field sits outside the leading names.
- Filing has cooled from a 2020 peak. Annual filings peaked at 1,908 in 2020 and fell 43% from 2021 (1,849) to 2024 (1,057), the last year the data can treat as complete given an 18-month publication lag.
- Momentum is fading even among leaders. Every assignee tracked for recent-year momentum shows a year-on-year decline, some over 90%, suggesting the current wave of core claims is largely staked out.
Filing growth compares 2021 (1,849 records) with 2024 (1,057) — 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 358,262 records in scope (CR5), not by the ranked leaders only.
What this landscape covers
This landscape maps 358,262 published records filed against a search spanning wireless communication, radio access networks, fifth-generation network architecture, satellite communications, spectrum management, wireless mesh networks, optical networking and network synchronization. The scope runs from 2015 through the 2026-07-31 data cut-off, and every figure on this page is drawn from that set rather than estimated. Records are attributed to 100 ranked assignees, the full list the underlying data endpoint returns, not a curated top-50 or top-100.
The picture that emerges is one of a mature, densely claimed core — wireless communication networks and digital information transmission carry the bulk of the classification weight — surrounded by thinner, more open branches in optical networking, network synchronization and AI-based network computing. Filing volume has already passed its peak, which changes how a freedom-to-operate search here should be framed: recent years are not evidence of a shrinking field so much as evidence that publication is still catching up with filing.
Filing trend and technology composition
Two views of the same 358,262-record set: how filing activity has moved year over year, and which IPC subclasses carry the claim density.
A decade of filing activity, and a clear peak behind us
Filings rose from 992 in 2017 to a peak of 1,908 in 2020, then declined 43% from 1,849 in 2021 to 1,057 in 2024 — the most recent year the trend can treat as complete. 2025 and 2026 figures are still filling in under the roughly 18-month publication lag and should not be read as a continuation of the decline.
Claim density sits overwhelmingly in wireless transmission
H04W (wireless communication networks) covers 4.4% of all 358,262 records and H04L (digital information transmission) covers 2.2%, together dwarfing every other subclass. Because a single record can carry multiple IPC codes, these shares are each measured against the full record total and are not mutually exclusive — G06N (AI-based network computing) at 0.2% is a useful marker of how much of the field's machine-learning framing is still small relative to the core radio and transmission classes.
Shares are the percentage of the 358,262 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Try EurekaA representative claim and the most-cited prior art
Spectrum management device, electronic device, radio communication method, and storage medium — Sony Group Corporation
The device sits inside a coexistence system covering at least two radio access networks that use different radio access technologies. It generates an interference overlapping graph for the coexistence system and allocates spectrum resources across the networks according to that graph — a coordination layer for spectrum sharing between heterogeneous RAN deployments rather than a single-network optimisation.Filed by Sony Group Corporation, published 2024-07-09.

Three read-throughs from the assignee ranking, the filing trend and the citation table.
Leadership is real but not a wall
The leader alone holds 45,808 records and the tenth-ranked assignee holds 3,509 — a steep drop-off inside the top 10 itself. With 55.7% of records held outside the top 10, there is substantial room for a well-targeted filing to sit clear of the biggest portfolios, provided it avoids the specific claim territory the leaders already occupy.
The volume wave has crested
Filing peaked at 1,908 records in 2020 and has fallen every complete year since, down 43% from 1,849 in 2021 to 1,057 in 2024. That does not mean the technology is exhausted — high filing density earlier in the decade means claim space around core radio access and transmission methods is occupied, which is a different signal from the field itself losing relevance.
The core is crowded, the edges are not
Wireless communication networks (H04W) and digital information transmission (H04L) carry the visible weight of this landscape. Subclasses like multiplex communication, switching and AI-based network computing sit an order of magnitude lower, which is where a freedom-to-operate review is more likely to find open claim language.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to telecommunications & next-generation networks patent landscape, with the prior art for and against each one.
Who is filing, and where activity is slowing even for leaders
The ranked assignees span device makers, network equipment vendors and mobile chipset suppliers. Recent-year momentum, though, points the same direction across the board: down.
Even top filers are pulling back
Every assignee tracked for recent-year momentum recorded a year-on-year decline, several exceeding 90%. That is consistent with a field where the core claim space around established radio access and transmission methods has already been substantially staked out by the leading portfolios.
Filing offices skew toward the US and EPO
The United States receiving office accounts for the largest single share of tracked filings, with the EPO and WIPO's PCT route also carrying meaningful volume. That distribution matters for where enforcement risk and prosecution cost concentrate for any new entrant.
Co-assignment is narrow and individual-led
Co-assignee activity is limited to ten identified pairs, with the strongest pairing appearing well over a hundred times together. This looks more like individual-inventor cross-filing than institutional joint ventures, and is not a major structural feature of the landscape.

Turning this landscape into a filing decision
The scale of this dataset means manual review only gets a team so far. The next steps are about narrowing from 358,262 records to the specific claims that matter for a given product or filing.
Map a specific claim against the crowded core
H04W and H04L carry most of the classification weight in this landscape. Before drafting in wireless communication network methods, a targeted prior-art pull against the leading assignees' recent filings will show exactly how much room is left.
Explore this landscape in EurekaTest white-space branches for real freedom to operate
Thinner subclasses like network synchronization and AI-based network computing look open at the composition level, but that needs confirming claim-by-claim, not just class-by-class.
Run a white-space check in EurekaWatch the momentum shift, not just the leaderboard
Every tracked leader's filing pace is down year-on-year. That is a signal to revisit assumptions about who is actively expanding coverage versus who is defending a filed position.
Track assignee momentum in EurekaCommon questions about this landscape
The assignee ranking in this dataset covers 100 companies, and the leader alone holds 45,808 of the 358,262 records in scope. The top 5 assignees together hold 36.6% of all records and the top 10 hold 44.3%, so while there is real concentration at the very top, more than half the field sits outside the ten largest portfolios. Anyone assessing freedom to operate should look at the specific claim language of the top filers rather than assume the whole field is locked up, since the long tail of remaining assignees still accounts for the majority of records.
No — filing peaked at 1,908 records in 2020 and has declined since, falling 43% from 1,849 filings in 2021 to 1,057 in 2024, the most recent year the data can treat as complete. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by around 18 months, so they understate true activity and should not be read as continuing the decline. The honest read is that the field passed its filing peak several years ago, not that it is currently in free fall.
Wireless communication networks (IPC class H04W) and digital information transmission (H04L) carry by far the most claim density, covering 4.4% and 2.2% of the 358,262 records in scope respectively. Other classes such as multiplex communication, switching and selecting, and AI-based network computing sit well below 1% each. Because a single record can carry multiple IPC codes, these figures do not sum to a total field share — they show where density concentrates, not an exhaustive breakdown.
The composition data points to subclasses with much lower filing density than the core wireless and transmission classes, including network synchronization, optical networking, multiplex switching for mesh topologies, and AI-based spectrum allocation. Low density in the composition chart is a starting signal, not a guarantee of freedom to operate — it needs confirming against the actual claim scope of records already filed in those subclasses. It does, however, tell a filing team where to look first rather than starting a review across the entire 358,262-record set.
US12035144B2, assigned to Sony Group Corporation and published 2024-07-09, covers a spectrum management device that generates an interference overlapping graph for a coexistence system containing at least two radio access networks using different radio access technologies, then allocates spectrum resources based on that graph. It is specific to coordinating spectrum across heterogeneous RAN types rather than optimising a single network. Work that shares spectrum within one radio access technology, or that uses a different coordination mechanism than an interference overlapping graph, sits outside its literal claim scope, though a full clearance review should check the granted claims directly rather than relying on the abstract.
