Remote Attestation Patents: Who Leads, Where the Gaps Are 2026
Remote Attestation Protocol Patents: Filing Trends and Leaders
Concentrated at the top. The five leading assignees hold 34.5% of all 1,788 of the 5,188 records in scope, and the leading ten hold 46.2% (2,395 records) — but a long tail of single- and few-filing entrants fills the rest. Filings rose to a peak of 371 in 2019, then eased to 198 by 2024 (down 22% from 255 in 2021). 2025 and 2026 figures are still incomplete because publication typically lags filing by around 18 months, so the recent downturn should be read cautiously rather than as a confirmed slowdown.

Frequently asked questions
Who holds the most patents in remote attestation protocols?
Filing in this space is concentrated at the top: the five leading assignees together hold 34.5% of all 5,188 records in scope, and the leading ten hold 46.2%. The single leading assignee alone accounts for 586 records, more than three times the fifth-placed company’s 194. Beyond the leading ten, however, filing spreads across a long tail of companies and individual filers with much smaller portfolios, so the field is not a two- or three-way contest despite the concentration at the top.
Is remote attestation patent filing activity growing or slowing?
Filing peaked in 2019 at 371 records and eased to 198 by 2024, a 22% decline from the 255 filed in 2021. That said, patent publication typically lags filing by around 18 months, so the apparent drop-off in 2025 and 2026 numbers is partly an artefact of incomplete data rather than a confirmed slowdown. The fairer read is that the field has cooled from its 2019 peak but has not collapsed, and 2024 is the most recent year with a reasonably complete count.
What technology areas are most heavily claimed in remote attestation?
Core digital data processing (IPC class G06F) appears on 71.4% of the 5,188 records, and digital information transmission (H04L) appears on 56.4%, making these the most heavily claimed areas by far. Wireless communication networks (H04W) and business-process applications (G06Q) form a distant second tier. Because a single record can carry multiple IPC classes, these shares add up to more than 100%, which is expected and simply reflects overlapping claim scope.
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.
