RF & Mixed-Signal Device Patents: Who Leads and Where Claims Are Still Open
Concentrated but not locked up. the top 5 assignees hold 34.3% of all 2,568 records in scope, and the top 10 hold 47.6% — meaning more than half of the field sits with a long tail of single- or few-filing entrants. Annual filings rose from 52 records in 2017 to a peak of 228 in 2018, then eased over subsequent years. The last full-year comparison available shows 119 records in 2021 falling to 102 in 2024, a 14% decline over that span. 2026 is shown at 13 records but is a partial year and should not be read as a drop-off.

Common questions about RF and mixed-signal device patents
Who holds the most patents in RF and mixed-signal circuit design?
The leading assignee in this corpus holds 351 records, well ahead of the fifth-place holder at 100 and the tenth-place holder at 60. The gap from first to fifth is much steeper than the gap from fifth to tenth, meaning the field has one clearly dominant filer followed by a more tightly packed group of mid-tier competitors. Beyond the top 10, ownership spreads across a long tail of assignees who together still account for more than half of all 2,568 records, so a single-company view understates how fragmented the broader field is.
Is RF and mixed-signal patent filing growing or slowing down?
Filing peaked at 228 records in 2018 and has eased since, with the most reliable complete-year comparison showing 119 records in 2021 declining to 102 in 2024, a 14% drop. That is a real pullback, not a sign the technology is exhausted — high filing density in earlier years reflects claim space being staked out, not necessarily faster innovation. Figures for 2025 and 2026 will revise upward over time because publication typically lags actual filing by about 18 months, so those years should not yet be read as continuing the decline.
Which patent classes cover the most RF and mixed-signal device claims?
H04B, the general transmission class, appears in 34.3% of the 2,568 records in scope, the largest single share. H04L (digital information transmission) follows at 18.0% and H01L (semiconductor devices) at 15.6%, with control-system claims under G05B and AI-model claims under G06N each present in around 13% of records. Because a single patent can carry multiple IPC codes, these shares add up to more than 100% of the record total — they describe overlapping claim coverage, not mutually exclusive categories.
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.
