Blind Rivet Patents: Top Companies & Filing Trends 2026
Blind Rivet and Mechanical Joining Patents: Who Leads and Where Claims Concentrate
Top 5 hold 58.4% of the field. 258 of 442 records in scope sit with the five leading assignees, leaving a long tail of single- and low-filing entrants. Filings peaked at 14 in 2018, cooled in the early 2020s, then climbed again from 4 in 2021 to 7 in 2024 — a +75% rise over that three-year span. 2025 and 2026 figures are still filling in due to publication lag and should not be read as a slowdown.

Common questions about blind rivet and mechanical joining patents
Who holds the most patents on blind rivet technology?
One assignee holds 197 of the 442 records in this dataset, well ahead of the fifth-place holder at 12 records. That gap indicates a long-standing, concentrated filing programme rather than a recently arrived competitor. Anyone evaluating freedom to operate in blind rivet setting mechanisms should start their prior-art review with that leader’s portfolio before looking at the rest of the field.
Is patent filing activity in blind rivets and mechanical joining increasing or slowing down?
Filings rose from 4 in 2021 to 7 in 2024, a +75% increase over that three-year span, after an earlier peak of 14 in 2018. The apparent dip in 2025-2026 figures is a publication-lag artefact — patent applications typically take about 18 months to publish — so those years should not yet be read as a slowdown. The complete-year trend through 2024 points to renewed rather than declining activity.
What technology areas do blind rivet patents cover most heavily?
B21J (forging and hammering) and F16B (fasteners including bolts and rivets) each appear in roughly half of the 442 records in scope, making them the dominant claim territories. Supporting classes like B23P general metal working, B21D sheet-metal working and B29C plastics shaping appear far less often, each under 12%. This split shows the field’s technical centre of gravity sits squarely in mechanical rivet-setting and fastener structure rather than in adjacent processes like welding.
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.
