Two Dimensional Materials for Transistors: Patents, Leaders and Where Filing Has Cooled
Concentrated at the top. the leading assignee holds 207 records and the top 5 combined account for 37.9% of all 1,118 records in scope. Filings rose from 72 in 2017 to a peak of 142 in 2020, then eased. From 2021 (112) to 2024 (75) — the most recent year that can be treated as complete — filings fell 33%. 2025 and 2026 figures are still filling in under the usual publication lag and should not be read as a continuation of that decline.

Common questions on this landscape
Who holds the most patents on two-dimensional material transistors?
One assignee leads the ranked list with 207 records, well ahead of fifth place at 44 and tenth place at 20. The top 5 assignees combined account for 37.9% of all 1,118 records in this dataset, and the top 10 account for 49.4%, so filing activity is concentrated among a small group rather than spread evenly. A freedom-to-operate check in this space should start with that leading group’s claim scope before looking at the long tail of single- or few-filing entrants.
Is patent filing in 2D material transistors growing or slowing down?
Filings rose steadily to a peak of 142 records in 2020, then declined to 112 in 2021 and 75 in 2024, a 33% drop over that three-year span using only complete years. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by about 18 months, so the most recent years will rise as more records publish. It is accurate to say filing has pulled back from its 2020 peak, but premature to call the field currently declining based on the newest data points.
Which patent classes cover 2D material transistor technology?
The largest share, 52.9% of the 1,118 records, falls under H01L (semiconductor devices), with a further 23.3% under H10D. Materials-process classes such as coating and deposition (C23C, 11.3%), inorganic compounds (C01B, 9.8%), materials testing (G01N, 8.9%) and crystal growth (C30B, 7.7%) appear at lower density. A single record can carry several of these classes, so the shares add to more than 100% and should not be treated as 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.
Method: Filing trend and technology composition. Derived from a Patsnap search on Two Dimensional Materials for Transistors 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.
