UWB Impulse Radio Patents: Top Companies & Filing Trends 2026
UWB impulse radio and interference mitigation patents: who holds the ground and where it is still open
30.0% concentration at the top. The five leading assignees together hold 1,554 of the 5,179 records in scope — a concentrated field, but not a closed one. Filings rose from 312 in 2017 to a peak of 348 in 2019, then eased to 215 by 2024 — a -7% move from 2021's 232. Years from 2025 onward are still filling in as publications catch up with filing dates, so the apparent tail-off there is not yet a reliable signal.

Common questions about UWB impulse radio patents
Who holds the most patents in UWB impulse radio and interference mitigation?
One assignee leads the ranked field with 815 records, well ahead of the fifth-placed assignee at 116. The top five assignees together account for 1,554 records, or 30.0% of the 5,179 records in scope, so the field is concentrated at the top but still has 70% of filings spread across a long tail of other entrants. Recent-year momentum data shows several of these same leaders filing at a slower pace than their cumulative totals would suggest, so current rank and current activity are not the same thing.
Is UWB impulse radio patent filing activity growing or slowing?
Filing peaked at 348 records in 2019 and eased to 215 by 2024, a -7% change over that three-year window using the last years that can be treated as complete. That is a plateau rather than a collapse. Counts for 2025 and 2026 appear lower still in the raw trend, but that is expected: publication typically lags filing by around 18 months, so the newest years always look artificially thin until more records catch up.
What technology areas does UWB interference mitigation patenting cover?
The corpus spans transmission-layer classes (H04B, 38.7% of records), wireless network classes (H04W, 33.9%) and digital transmission classes (H04L, 30.0%) most heavily, with radar, sonar and positioning classes (G01S) at 18.7%. Smaller shares sit in multiplexing (H04J), antennas (H01Q), pulse and logic circuitry (H03K) and digital data processing (G06F). Because a single record can carry several IPC codes, these percentages add up to more than 100% of the 5,179 records and should be read as coverage shares, not a partition.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
