Glass Texturing and Antiglare Etching Patents: Who Leads 2026
Glass texturing and antiglare etching patents: one assignee's lead, and where the field is still open
One assignee dominates recent activity. Corning logged 2 filings in the most recent year while every other tracked assignee shows 0 — a lead with no immediate second mover. From a single filing in 2017, activity rose unevenly to a peak of 3 filings in 2023. The growth signal the dataset supports is the 2021-to-2024 span: 2 filings to 3, a +50% increase. 2025 and 2026 figures are still filling in under publication lag and should not be read against that trend.

Common questions on this landscape
Who holds the most patents in glass texturing and antiglare etching?
Within the 8 assignees covered by this dataset’s ranking, one company leads clearly with 10 records against a fifth-place figure of just 1. That company also accounts for the only recent-year filing activity recorded, with 2 filings in the latest year while every other ranked assignee shows 0. This is a concentrated but small field, so the ranking should be read as directional rather than exhaustive of every filer worldwide.
Is filing activity in antiglare glass patents growing or slowing down?
The usable growth figure is +50% from 2021 (2 filings) to 2024 (3 filings), with a peak of 3 filings already reached in 2023. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by around 18 months, so they should not yet be read as a decline. On the evidence available through 2024, the trend is upward off a small base.
What does US20250208317A1 actually cover?
This Corning filing, published mid-2025, describes an antiglare article with a textured primary surface meeting specific optical thresholds: specular reflectance at or below 0.2% at 20° from normal, transmittance haze under 35%, sparkle under 3% on a 140 PPI device, distinctness of image under 35%, and color separation under 0.6. It is the newest of the most-cited records in this dataset and the most tightly specified in terms of measurable optical performance. Anyone designing a competing antiglare surface should check their own measured values against these five thresholds directly.
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 Glass Texturing and Antiglare Etching 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.
