Quantum Materials & Devices Patents: Who Leads, Where the Gaps Are 2026
Quantum Materials & Devices Patents: Who Is Filing and Where the Field Is Still Open
62.2% of all 90 records sit with just five assignees, but the ranking still runs to 36 companies — a concentrated top with a long single-filing tail below it. Filings climbed from 7 in 2017 to a peak of 21 in 2024, including the +91% run from 11 in 2021 to 21 in 2024. 2025 and 2026 show fewer records so far, consistent with publication lag rather than a slowdown.

Common questions on quantum materials and devices patenting
Who holds the most patents in quantum materials and devices?
One assignee leads with 16 of the 90 records in scope, roughly twice the count held by the fifth-place company at 7. The top five assignees together hold 62.2% of all 90 records, and the top ten reach 86.7%, so the field is concentrated at the top even though the full ranking runs to 36 companies. Below the top ten the counts fall quickly to single-digit and single-filing entrants, forming a long tail rather than an even spread.
Is quantum materials and devices patent filing growing or slowing?
Filings grew from 11 in 2021 to a peak of 21 in 2024, a 91% increase over that span, which is the clearest read of momentum in this dataset. 2025 and 2026 show fewer published records, but that reflects publication lag of roughly 18 months rather than an actual drop in filing activity. Treat 2024 as the last year in the trend that can be read as complete.
What technology areas dominate quantum materials and devices claims?
G06N, covering AI-based computing methods, appears in 80.0% of the 90 records in scope, far ahead of any other class. G06F (electric digital data processing) and G16C (computational chemistry) follow at 15.6% and 13.3% respectively. Hardware- and materials-specific classes such as H01L, H10D, B82Y and C09K each sit under 8%, indicating that claims in this dataset skew toward control and computational methods rather than the physical device or material stack.
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 Quantum Materials & Devices Patent Landscape covering 2015–2026, data cut-off 2026-08-31. 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.
