Patent Landscape · Wireless CommunicationsTerahertz Communication and Sensing Patents: Who Is Filing and Where the Field Is Still Open
- Flat, not rising. filings peaked at 6 in 2022 and have not exceeded that since, with 2026 (partial) sitting at 4 — this is not a technology in a filing boom.
- Sensing rivals transmission. G01N material-analysis claims (15 records) sit almost as dense as H04B transmission claims (18), meaning sensing is not a side branch of a communications field but a co-equal claim territory.
- China dominates the office split. 20 of the tracked filings were received in China against 10 in the United States, so freedom-to-operate review has to start with the Chinese register, not the USPTO.

Overview
What the terahertz patent record actually covers
Terahertz communication and sensing sits at the junction of three older disciplines: RF transmission engineering, optical-band material analysis, and antenna design. The dataset behind this page pulls records where the claims reference source generation, atmospheric attenuation, detector responsivity, imaging resolution, or waveguide structures, filtered to H04B10, G01N21 and H01Q13. That combination captures both link-budget engineering for terahertz communication links and spectroscopic or imaging sensing built on the same hardware primitives — sources, detectors, and waveguides that carry or read a terahertz signal.
39 patent families were identified across the 2015–2026 window, with the earliest filing activity in this set beginning in 2017. Publication lags filing by roughly 18 months, so the 2025 and 2026 figures in any trend line understate real filing activity for those years.

The data
Filing trend and technology composition
Two views of the same 39-family dataset: how filing activity has moved year over year, and how those filings split across IPC subclasses.
Filings plateaued after 2022
Activity climbed from zero in 2017 to a peak of 6 families in 2022, then held flat or declined through the most recent complete years. With 2026 only partially reported at 4, there is no clear inflection yet distinguishing this from a mature, steady-state filing pattern rather than an emerging one.
Transmission and sensing claims are close in volume
H04B (transmission, 18 records) leads narrowly over G01N (material analysis and testing, 15 records), with H01Q (antennas, 10) a clear third. Smaller pockets in H01S (lasers, 4), H04L (digital transmission, 4), B82Y (nanotechnology, 3), G01J (radiation measurement, 3) and G01V (geophysics, 3) show where terahertz hardware is being adapted into adjacent measurement disciplines rather than treated as a self-contained field.
Shares are the percentage of the 39 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Terahertz sensing system and terahertz sensing array (Huawei)
HUAWEI TECHNOLOGIES CO., LTD.
A terahertz sensing system and array in which N sensing unit groups, each containing M reconfigurable sensing units, are arranged so that individual units can be reconfigured to detect different terahertz wave physical characteristic parameters. The claim structures the array around reconfigurability at the unit level rather than fixing each unit to a single measurement type.Filed by Huawei Technologies Co., Ltd., published 2022-10-06.

Citation counts are drawn from within the searched corpus and skew toward older filings that have simply had more time to accumulate citations — treat them as a signal of influence on the field's foundational claims, not of current commercial relevance.
Patent titles are shown in the language they were filed in, not translated, so that each record stays verifiable against the original filing — a translated title will not match in Eureka or in any national register. Each row carries its publication number; clicking a row searches Eureka by that number.

What the numbers mean for a filing strategy
Three patterns stand out once the raw counts are put in context: where the claim density actually sits, who is filing together, and what the citation record signals about foundational versus current work.
Claim density
18 vs 15
H04B vs G01N records
Sensing is not a minor branch
H04B transmission claims lead G01N sensing claims by only three records out of 39. A filer entering this space purely on the communications side will still need to clear a sensing-claims prior art review, because the two subclasses overlap heavily on source and detector hardware.
IPC composition, 39 families
Filing offices
20 / 10 / 4 / 4 / 1
China / US / India / WIPO / Japan
China is the primary filing jurisdiction
Twice as many tracked filings were received in China as in the United States, with India and WIPO PCT filings tied at four each. Any freedom-to-operate check that starts and ends with the USPTO register will miss the majority of the documented activity.
Receiving office split
Collaboration pattern
9 pairs
co-assignee pairings identified
Filing is mostly solo, with a few dense pairs
Only nine co-assignee pairs were identified across the dataset, and the strongest pairing recurs across multiple joint filings rather than being a one-off. That points to a small number of individual-plus-institution collaborations doing repeated joint work, alongside a larger population of single-assignee filers.

Players
Who is filing, and where the gate sits for new entrants
With only 39 families total, no single assignee holds a commanding share of this field. Momentum data shows the named assignees below all recorded zero filings in the most recent year, consistent with a plateaued rather than accelerating filing pattern.
Filer profile
0 in latest year
YoY momentum, top assignees
No assignee is currently accelerating
Every assignee surfaced in the recent-momentum data, including established filers with historical volume, shows zero filings in the latest tracked year. This is consistent with the broader plateau seen in the annual trend rather than any single company retreating from the space.

Huawei
Large corporates hold selective positions
Huawei's terahertz sensing array filing shows a large communications-equipment vendor staking a claim in reconfigurable sensing hardware specifically, rather than filing broadly across the terahertz stack. That selective pattern is worth watching for where else major vendors choose to file.

FAQ
Common questions about terahertz communication and sensing patents
This dataset tracks 39 patent families filed between 2017 and 2026 under a search combining terahertz communication and sensing terminology with IPC classes H04B10, G01N21 and H01Q13. That is a modest field by patent-landscape standards, meaning claim territory is not yet saturated in most sub-branches. The true figure for very recent years will be higher once publication catches up, since patent publication typically lags filing by around 18 months.
The assignee base is fragmented rather than concentrated, mixing Chinese university filers, a dedicated terahertz research institute, and individual inventors filing jointly with academic institutions such as MIT. Huawei appears with a notable filing in reconfigurable terahertz sensing arrays, showing large communications-equipment vendors taking selective rather than broad positions. No single filer holds a commanding share of the 39-family dataset, so competitive monitoring needs to track a distributed set of players rather than one or two dominant names.
Filing activity rose from zero in 2017 to a peak of 6 families in 2022, then plateaued: the 2026 figure (partial, at 4) has not exceeded that 2022 peak. Every major assignee in the recent-momentum data recorded zero filings in the latest tracked year. That pattern is more consistent with a field that has settled into steady, incremental filing than one in an active growth phase, though publication lag means the very latest year is always undercounted.
Communication-focused claims cluster in IPC class H04B (transmission, 18 records), covering source generation, waveguide structures and link-level signal handling. Sensing-focused claims cluster in G01N (material analysis and testing, 15 records), covering detector responsivity and spectroscopic or imaging applications built on similar terahertz hardware. The two subclasses are close in volume, and many underlying components — sources, detectors, waveguides — are shared between them, so a filing in one area often needs prior art clearance in the other.
Relative to the dense H04B and G01N claim territory, sub-areas such as atmospheric attenuation compensation algorithms, on-chip waveguide integration, and reconfigurable sensing unit arrays show thinner filing density in this dataset. These are not unclaimed, but they carry less prior art weight than the core transmission and detector claims. A first filer in these branches would want to check the existing reconfigurable-array claims, such as Huawei's terahertz sensing array filing, before drafting around them.
