Copper Chromium Zirconium Electrode Patents: Leaders & Trends 2026
Copper Chromium Zirconium Resistance Welding Electrode Patents
25.4% of all 382 records sit with just five assignees, so the field reads as concentrated at the top with a long tail below it. The peak year so far is 2017 at 21 records. Filing growth in the most recent complete window is positive: 2021's 2 records rose to 2024's 5, a 150% increase — read this against the trend rather than the raw 2025-2026 tail, which is still incomplete due to publication lag.

Common questions about this landscape
Who holds the most patents on copper chromium zirconium welding electrodes?
The leading assignee in this dataset holds 21 of the 382 records in scope, with the fifth-ranked company at 18 and the tenth at 10. Together the top five hold 25.4% of all records, and the top ten hold 42.4%. No single company dominates outright, but filing activity is clearly weighted toward a handful of established industrial names rather than spread evenly across the 100 ranked companies.
Is filing activity in this space growing or slowing down?
Filing grew from 2 records in 2021 to 5 in 2024, a 150% increase over that window, which is the most recent period this dataset can treat as complete. The 2017 peak of 21 records is still the high point in raw terms. Figures for 2025 and 2026 look lower, but that reflects the roughly 18-month lag between filing and publication rather than an actual drop in activity.
What is the difference between CuCrZr electrode patents and general resistance welding electrode patents?
This dataset captures both: claims specific to the copper chromium zirconium alloy system and broader resistance welding electrode claims covering geometry, cooling, and wear behaviour. The IPC composition shows B23K (welding, soldering and brazing) present in 72.0% of records, while C22C (alloys) appears in 13.4%, indicating most filings frame their claims around the welding process and electrode structure rather than the alloy composition alone.
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 Copper Chromium Zirconium Resistance Welding Electrodes 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.
