RF Switches and SOI Patents: Who Leads, Where the Gaps Are 2026
RF switch and silicon-on-insulator patents: who holds the claim space and where it is still open
Concentration at the top. The five leading assignees hold 958 of 2,504 records in scope (38.3%), and the leading ten hold 1,233 (49.2%) — roughly half the field sits with ten organisations. Filings rose to a peak of 191 in 2018, then eased. The clearest complete-year comparison, 2021 (138) to 2024 (99), shows a 28% decline — but 2025 and 2026 figures are still incomplete due to publication lag and should not be read as a continuing drop.

Common questions about RF switch and SOI patents
Who holds the most RF switch and SOI patents?
The ranking covers 100 assignees, and it is heavily top-weighted: the leading assignee holds 405 of the 2,504 records in scope, more than double the fifth-place holder’s 70. The five leading assignees together hold 958 records (38.3% of the field), and the leading ten hold 1,233 (49.2%). Past the top ten, filing counts fall off sharply into a long tail of companies with far fewer records each, so competitive mapping should treat the leaders and the tail very differently.
Is RF switch and silicon-on-insulator patent filing slowing down?
Filing peaked at 191 records in 2018 and has since eased; the clearest complete-year comparison, 2021 (138) to 2024 (99), shows a 28% decline. However, 2025 and 2026 figures in this dataset are still incomplete because publication typically lags filing by roughly 18 months, so those most recent years should not be read as proof the field is still falling. A fair read is that activity has cooled from its 2018 peak rather than collapsed.
What technology areas dominate RF switch and SOI patent claims?
H01L (semiconductor devices) and H03K (pulse technique and logic circuits) are the densest IPC subclasses, each appearing in roughly a third of the 2,504 records in scope (34.4% and 32.7% respectively). H04B (transmission, general) follows at 25.2%. Antenna-related claims under H01Q appear in only 7.8% of records, suggesting device- and architecture-level claims are far more heavily contested than antenna-integration claims.
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 RF Switches and Silicon on Insulator Technology 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.
