Coated Abrasive Belt and Disc Manufacturing Patents
Filing has cooled from its 2017 peak of 240. the tracked span shows a -67% move from 93 filings in 2021 to 31 in 2024, the last year publication lag lets us call complete. Filings peaked at 240 in 2017 and have declined since; 2021 to 2024 alone shows a -67% move from 93 to 31 filings. Treat 2025 and 2026 as incomplete — publication typically lags filing by around 18 months, so the most recent years will fill in as more records publish.

Common questions on this landscape
Who holds the most patents in coated abrasive belt and disc manufacturing?
One assignee leads the ranked list with 2,312 families, well ahead of the fifth-ranked company at 448 and tenth place at just 28. This gap indicates a long-standing, dominant portfolio rather than a recent entrant. The ranking covers 100 companies total, so beyond the leading handful, most assignees hold comparatively few families each, forming a long tail typical of a mature manufacturing field.
Is patent filing activity in coated abrasives growing or declining?
Filings peaked in 2017 at 240 and have fallen since, with the 2021-to-2024 span showing a -67% move from 93 to 31 filings. 2024 is the most recent year with reliable data because publication typically lags actual filing by around 18 months, so 2025 and 2026 figures will rise as more records publish. Read the recent apparent decline cautiously rather than as a settled downward trend.
What technologies are most heavily patented within this field?
Grinding tools and abrasives structures, classified under B24D, appear in 80.6% of the 5,609 records in scope, making it by far the densest claim area. Materials for miscellaneous applications (C09K) follow at 39.5%, and ceramics, cement and refractories (C04B) at 12.7%. Because a single patent can carry multiple classifications, these figures overlap rather than sum to a whole, but the ranking shows where claim space is most occupied.
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.
