Quartz and Ceramic Consumables Patents: Top Filers & Trends 2026
Quartz and Ceramic Consumables Patents: Who Files, What They Claim, and Where Room Remains
27.8% concentration at the top. The five leading assignees account for 288 of the 1,035 records in scope, but the next 90-plus ranked filers hold single-digit counts each — a long tail, not a duopoly. Volume ran from 22 records in 2017 to a peak of 34 in 2019, before settling into a lower, roughly stable band — 15 in 2021 and 16 in 2024, a +7% move over that three-year span. Treat 2025 and 2026 figures as undercounts still catching up.

Common questions about this landscape
Who holds the most patents on quartz and ceramic consumables for semiconductor equipment?
Filing activity in this dataset is led by one assignee with 86 of the 1,035 records in scope, well ahead of the fifth-place holder at 32 and tenth place at 16. The top five assignees combined hold 27.8% of all records, and the top ten hold 39.4%. Beyond that, the field has a long tail of ranked companies each holding small counts, so leadership is real but far from exclusive.
Is patent filing in this field growing or slowing down?
Filing volume peaked in 2019 at 34 records, dipped afterward, and has since held roughly steady — moving from 15 records in 2021 to 16 in 2024, a +7% change over that span. The most recent one to two years in any patent trend are always understated because publication typically lags filing by around 18 months, so 2025 and 2026 figures should not be read as a genuine slowdown. Overall, this reads as a mature, maintained filing category rather than one in decline or in fresh acceleration.
What technology areas do quartz and ceramic consumable patents actually cover?
The largest concentration sits in C04B, ceramics, cement and refractories, which touches 41.4% of the 1,035 records — more than three times the share of the next largest class, C03C glass and enamel compositions at 12.4%. Coating and surface deposition (C23C) and semiconductor devices (H01L) each account for roughly 10-12% of records, with smaller but consistent activity in catalytic processes, discharge tubes, batteries and heating circuits. Because a single record can carry multiple IPC classes, these shares add up to more than 100%, which reflects overlapping material, coating and device claims rather than any error in counting.
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.
