Inkjet-Printed TFT Patents: Top Companies & Filing Trends 2026
Inkjet-Printed Thin-Film Transistor Patents: Who Holds the Claim Space
65.2% of all 112 records in scope sit with just five assignees, and the top ten combined account for 98.2% — this is a field with almost no long tail left to claim. Filings peaked at 20 records in 2017 and have not matched that level in any complete year since; the 2026 figure of 0 reflects the partial year and publication lag rather than a stop in activity.

Common questions about inkjet-printed TFT patents
Who holds the most patents on inkjet-printed thin-film transistors?
The ranking in this dataset covers 37 companies, and the leading assignee holds 27 of the 112 records in scope, well ahead of the fifth-place holder at 10 records. The top five assignees together account for 65.2% of all records, and the top ten reach 98.2%, so the field is concentrated among a small group rather than spread evenly. Any competitive read of this space should start with that leading group’s claim sets rather than a broad market scan.
Is the patent landscape for inkjet-printed TFTs still growing?
Filing activity peaked in 2017 at 20 records and has not returned to that level in any complete year since. A reliable growth rate cannot be stated from this data because too few complete recent years remain once publication lag is accounted for. Publication typically lags actual filing by around 18 months, so the apparent drop in the most recent years likely overstates any real slowdown.
What technology areas do inkjet-printed TFT patents actually claim?
Over half of the 112 records touch H01L (semiconductor devices), and more than a quarter touch H10D, the general semiconductor-device subclass. Organic-semiconductor structures (H10K) and data-recognition integration (G06K) each appear in under a fifth of records, with nanotechnology (B82Y), laser processing (H01S) and digital transmission (H04L) trailing further behind. Because a single record can carry multiple IPC classes, these figures describe overlapping coverage rather than a clean split of the field.
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.
