Remote Attestation Patents: Who Leads, Where the Gaps Are 2026
Remote Attestation for Software Integrity: Patents, Leaders and Open Claim Space
Concentrated at the top. The leading assignee alone accounts for 24 of 71 records, and the top 5 combined hold 69.0% of all 71 records in scope. Annual filings climbed from 4 in 2017 to a peak of 12 in 2021, then fell to 5 by 2024 — a 58% decline over that three-year span. Because publication trails filing by roughly 18 months, 2025 and 2026 figures are still filling in and should not be read as a continued drop.

Common questions on this landscape
What is remote attestation for software integrity in patent terms?
In this landscape it refers to mechanisms that let one device or system prove to another, using cryptographic evidence, that its software has not been altered. The recurring technical elements are a root of trust, a measurement log recording boot or runtime state, and a signed attestation report that a verifier checks against a known-good platform configuration. Patents in this space typically claim some combination of the measurement step, the signing or reporting step, or the verification logic on the receiving end, rather than the underlying cryptography itself.
Who are the leading patent filers in remote attestation for software integrity?
The ranked list covers 22 companies, with the leading assignee holding 24 of the 71 records in scope — well ahead of the rest of the field. The top 5 assignees combined account for 69.0% of all 71 records, so filing is concentrated rather than evenly spread. Beyond the leader, the field thins quickly, with fifth and tenth place both sitting at only 2 records each.
Is patent filing in this space growing or slowing down?
Filing peaked in 2021 at 12 records and had fallen to 5 by 2024, a 58% decline over that three-year window. That is the most reliable read available, because publication typically lags actual filing by around 18 months, which means the 2025-2026 figures in this dataset are still incomplete and should not be read as evidence of a further slowdown. Anyone tracking this space should expect the 2025-2026 counts to rise as later publications catch up.
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 Remote Attestation for Software Integrity 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.
