2D Materials Patents: Top Companies & Filing Trends 2026
Two-Dimensional Materials Patents: Who Files, Where the Claims Sit
25.3% concentration at the top. The five most active assignees combined account for 241 of the 953 records in scope — a leadership cluster, not a single dominant filer. Annual filings climbed from 66 records in 2017 to a peak of 81 in 2019, dipped, then resumed climbing through the 2021-2024 window (30 to 51 records, +70%). The 2026 figure of 6 reflects only what has published so far this year, not an actual drop in filing activity.

Common questions about this landscape
Who are the leading patent filers in two-dimensional materials?
The ranked leaders span materials science institutions, medical implant makers and industrial tooling companies rather than a single dominant sector. The top assignee holds 75 records in this dataset, with the next four combined bringing the top-five total to 241 records, or 25.3% of the 953 records in scope. That gap between first place and the rest suggests one organisation has run a longer, more deliberate filing programme, while a broader group of active filers sits just behind it — the top 10 together reach 37.7% of all records, so no single company controls the field.
Is two-dimensional materials patent filing activity growing or slowing?
It is growing, based on the most reliable complete-year data available. Annual filings rose from 30 records in 2021 to 51 in 2024, a 70% increase over that three-year span. The apparent drop-off in 2025 and 2026 is a publication-lag artefact — patents typically publish around 18 months after filing, so the most recent one to two years in any dataset will always look artificially low and should not be read as declining interest.
Which application areas dominate two-dimensional materials patents?
Semiconductor devices (H01L) and implants or prostheses (A61F) are the two largest IPC subclasses, each covering roughly 12% of the 953 records in scope. Coating and surface deposition, non-metallic inorganic compounds, materials testing, layered laminates, nonwovens and dimensional measurement all follow closely behind, each exceeding 6% of records. Because a single patent can be classified under multiple subclasses, these shares add up to more than 100%, and the spread indicates the technology is being claimed across several downstream industries rather than converging on one dominant use case.
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 Patent Landscape covering 2015–2026, data cut-off 2026-08-31.
