Patent Landscape · Glass Coatings & Functional SurfacesGlass coating and functional surface patents: who holds the claim space and where it opens up
- One assignee holds 105 of 287 records in scope, and the top five combined account for 75.6% of all records — this field is concentrated at the very top, not spread across a competitive middle tier.
- Filings grew 513% from 2021 to 2024 (8 to 49), with 2024 the peak year so far; 2025-2026 figures are still filling in as publication lags filing by roughly 18 months.
- C03C glass compositions cover 37.6% of records, but G02B optical elements (21.3%) and H04R audio transducers (6.6%) point to coating claims migrating onto wearable and device glass, not just flat sheet.

Leading Jurisdiction
Filing growth compares 2021 (8 records) with 2024 (49) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 287 records in scope (CR5), not by the ranked leaders only.

Overview
What this landscape covers
This dataset tracks 287 published records filed between 2015 and 2026 that combine glass functional coatings — oleophobic, antimicrobial and related surface treatments — with claims tied to durability, deposition method, optical transmission, adhesion or regulatory compliance. The search string requires both a coating/glass term and a performance or process term, so the corpus skews toward records that specify how a coating is made or how it is proven to work, rather than broad materials disclosures.
Filing activity is uneven across the window: single digits in the earliest years, a sharp climb through the early 2020s, and a 2024 peak of 49 records. Because publication trails filing by around 18 months, the 2025 and 2026 counts in the trend chart are not a slowdown signal — they are incomplete data still arriving.

The Numbers
Filing trends and technology composition
Two views of the same 287-record corpus: how filing volume moved year over year, and which IPC subclasses the claims fall under. A record can sit in more than one subclass, so the composition shares add up to more than 100%.
A five-year climb, then a data lag
From 20 records in 2017 to a peak of 49 in 2024, filings rose in almost every window; the 2021-to-2024 span alone grew 513%. Treat 2025 and 2026 as under-counted rather than declining.
Glass chemistry dominates, but device classes are rising
C03C (glass and enamel compositions) covers 37.6% of the 287 records, confirming this is still primarily a materials-chemistry field. But G02B (optical elements, 21.3%), G06F (digital data processing, 17.8%) and H04R (audio transducers, 6.6%) show coating claims increasingly attached to cover glass on cameras, displays and wearable devices rather than architectural or automotive sheet glass alone.
Shares are the percentage of the 287 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Described herein are various antimicrobial glass articles that have improved resistance to discoloration when exposed to harsh conditions. The improved antimicrobial glass articles described herein generally include a glass substrate that has a low concentration of nonbridging oxygen atoms, a compressive stress layer and an antimicrobial silver-containing region that each extend inward from a surface of the glass substrate to a specific depth, such that the glass article experiences little-to-no discoloration when exposed to harsh conditions. Methods of making and using the glass articles are also described.US20150225287A1 · Corning Incorporated · filed 2015-08-13

What the data means for a filing decision
Three patterns stand out once the ranking, the trend and the citation table are read together.
Concentration
75.6% of 287 records
held by the top five assignees
A narrow leadership group, not a crowded field
The leader alone accounts for 105 of the 287 records in scope, and the top five combined reach 75.6%. Anyone filing a new claim in core antimicrobial or chemically-strengthened glass chemistry is filing into space that a small number of parties already occupy densely.
Assignee ranking, 62 companies
Growth
+513%
2021 to 2024 filing growth
Momentum built fast, then the data lag hides the tail
Filings rose from 8 in 2021 to 49 in 2024, a genuine acceleration rather than noise. The 2025-2026 counts look lower only because publication has not caught up with filing yet; they should not be read as a cooldown.
Filing trend, 2017-2026
Composition
37.6% vs 21.3%
C03C glass chemistry vs G02B optics
Chemistry still leads, but device optics is the fastest-growing overlap
Glass and enamel composition claims (C03C) remain the largest single class, but optical elements (G02B), digital processing (G06F) and audio transducers (H04R) collectively show coatings claimed alongside camera, display and wearable hardware — a different competitive set than traditional glass chemistry alone.

Filing is largely solo, not collaborative
The strongest co-assignee links pair a named inventor with a single corporate assignee rather than linking two separate companies, suggesting internal R&D teams rather than cross-licensing or joint development.

What's Next
Where to take this next
The landscape points to specific next steps depending on whether the goal is freedom-to-operate, competitive tracking or new claim drafting.
Check freedom-to-operate against the leader's portfolio
With one assignee holding 105 of 287 records, any new antimicrobial or chemically-strengthened glass filing should be checked against that portfolio's claim scope before drafting.

FAQ
Common questions about glass coating patents
One assignee leads with 105 of the 287 records in scope, well ahead of the rest of the ranked field. The top five assignees combined account for 75.6% of all records, and the top ten reach 89.2%, so the field is concentrated among a handful of established players rather than spread across many competitors. The leader's program centres on antimicrobial and chemically-strengthened glass, visible in both filing volume and the most-cited records in this corpus.
Filings grew sharply, rising 513% from 8 records in 2021 to 49 in 2024, which was the peak year in this dataset. The apparent drop in 2025 and 2026 is not a real slowdown — publication typically lags filing by about 18 months, so the most recent one to two years of any patent trend are always undercounted. Based on the 2021-2024 trajectory, the underlying filing rate was still climbing as of the last complete year.
Glass and enamel compositions (C03C) cover 37.6% of the 287 records, making chemistry the dominant single category. Optical elements and systems (G02B) follow at 21.3%, and electric digital data processing (G06F) at 17.8%, with smaller but notable overlaps in audio transducers (H04R, 6.6%) and layered products (B32B, 7.3%). This spread shows coating claims are no longer confined to flat glass chemistry alone; they increasingly attach to camera, display and wearable device hardware.
Relative to the dense core chemistry claims, several branches show thinner filing: coating adhesion and durability testing on curved or wearable glass surfaces, deposition methods for multi-layer optical stacks, and antimicrobial coatings framed specifically around regulatory compliance testing. These are not zero-filing areas, but the density is noticeably lower than in core antimicrobial or chemically-strengthened glass chemistry, making them reasonable starting points for a freedom-to-operate review before drafting new claims.
The most-cited record in this corpus, US20120034435A1, covers coated antimicrobial chemically-strengthened glass and its method of manufacture, cited 235 times within this dataset. High citation counts in a searched corpus tend to favour older filings simply because they have had more years to accumulate references, so this should be read as a signal of influence on the field's early direction rather than a statement that the claims are still the most commercially relevant today.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
