RDMA Networking Patents: Top Companies & Filing Trends 2026
Remote Direct Memory Access Networking Patents
42.8% concentration. The five leading filers together hold 1,936 of 4,527 records in scope — nearly half the field sits with a handful of companies. Annual filings climbed from 211 in 2017 to a peak of 446 in 2021, then declined to 314 by 2024 — a 30% drop over that three-year window. 2025 and 2026 figures are still incomplete because publication typically lags filing by around 18 months, so the most recent years will fill in as more records publish.

Common questions about RDMA networking patents
Who are the leading patent holders in RDMA networking?
The field is led by a single assignee holding 522 of the 4,527 records in scope, well ahead of the fifth-ranked holder at 211. The top five assignees combined account for 42.8% of all records, and the top ten reach 57.4%. This concentration includes established server, networking-silicon and hyperscaler companies, meaning most core queue-pair, memory-registration and completion-queue mechanics are already covered by a small group of portfolios.
Is RDMA patent filing activity growing or slowing down?
Filings rose from 211 in 2017 to a peak of 446 in 2021, then declined to 314 by 2024 — a 30% drop over that three-year span. Because publication typically lags filing by around 18 months, the 2025 and 2026 figures in this dataset are still incomplete and should not be read as evidence of a continued decline. The honest read is that the intense early-2020s filing surge has passed its peak, not that interest in the technology has ended.
What technology areas do RDMA patents actually cover?
Three-quarters of records (74.5%) carry a G06F classification for electric digital data processing, and just under half (48.1%) carry H04L for digital information transmission, reflecting RDMA’s core position between data-path processing and network transport. Smaller classes covering multiplexing, static memory, wireless networks, imaging and video each account for under 2% of records, indicating these are peripheral rather than central to how RDMA has been claimed.
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.
