Ultrasound Transducer Array Patents: Who Leads, Where Gaps Are 2026
Ultrasound transducer array patents: mapping who holds the claims and where the design space is still open
Concentrated at the top. The five leading assignees hold 131 of 282 records in scope (46.5%), with the leader alone at 45 records — a steep drop to the rest of the ranked field. Volume rose to a peak of 19 records in 2021, then declined to 9 by 2024 — a 53% drop over three years. Records for 2025 and 2026 are still partial because publication typically lags filing by around 18 months, so the most recent bars will fill in as later-filed applications publish.

Common questions on ultrasound transducer array patents
Who holds the most patents on ultrasound transducer array design?
Within this 282-record dataset, one assignee leads with 45 records, well ahead of the fifth-ranked assignee at 15. The top five assignees together account for 131 records, or 46.5% of all records in scope. Beyond the tenth-ranked assignee (8 records), the field spreads into a long tail of companies with only a handful of filings each, typically tied to specific probe or materials niches.
Is ultrasound transducer array filing activity growing or declining?
Filing peaked at 19 records in 2021 and had fallen to 9 by 2024, a 53% decline over that three-year span. However, publication typically lags filing by around 18 months, so the 2025 and 2026 figures in any dataset are necessarily incomplete and should not yet be read as confirming a continued decline. A clearer read on the current trend will only be possible once those years finish publishing.
What technology areas dominate ultrasound transducer array patents?
The A61B subclass (diagnosis and surgery) covers 78.0% of the 282 records, and B06B (mechanical vibration generation) covers 37.9%, reflecting the medical-imaging core of this field. Because a single record can carry multiple IPC codes, these percentages overlap and sum to more than 100%. Adjacent classes tied to materials and solid-state integration, such as H10N and H01L, sit far lower at 10.3% and 6.7% respectively, indicating comparatively less claim density there.
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.
Method: Filing trend and technology composition. Derived from a Patsnap search on Ultrasound Transducer Array Design covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
