Platinum Group Metal Processing Patents: Leaders & Filing Trends 2026
Platinum Group Metal Processing Patents: Who Holds the Ground and Where It's Open
Concentrated at the top. the top 5 assignees hold 30.4% of all 359 records in scope, and the top 10 hold 49.0% — half the field sits with ten organisations. Filings ran from 4 in 2017 up to a peak of 39 in 2021, then fell to 8 by 2024 — a -79% move over that three-year span. 2025 and 2026 figures will rise as publication lag closes, so treat the tail of the chart as incomplete rather than as a continued decline.

Common questions on PGM processing patents
Who are the leading patent holders in platinum group metal processing?
The ranking covers 100 companies across 359 records in scope, with the leading assignee holding 29 records compared with 14 at fifth place and 11 at tenth. The top 5 combined hold 30.4% of all records, and the top 10 hold 49.0%, so roughly half the field sits with a small group while the remainder is spread across a long tail of lower-count filers. This structure means a full landscape review should look past the leader to the tenth-to-fiftieth positions, where meaningful but less visible activity sits.
Is patent filing in PGM processing growing or slowing down?
Filings peaked at 39 in 2021 and fell to 8 by 2024, a -79% move over that three-year span. Because publication typically lags filing by around 18 months, the 2025 and 2026 figures in any trend chart are still incomplete and will rise as more records publish. The honest read is a correction after a 2021 filing spike rather than confirmed long-term decline, and any claim about the field slowing should stop at 2024, the last complete year.
Which technology areas see the most patent activity in this space?
Metal extraction and refining (IPC class C22B) appears on 63.0% of the 359 records in scope, making it by far the most common classification. Catalysis-related processes (B01J) follow at 32.3%, with hydrocarbon oil refining crossover (C10G) at 14.8%. Because a single record can carry multiple IPC classes, these percentages add up to more than 100% and should be read as independent shares of the same 359-record base, not as parts of a whole.
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.
