Metal AM Directed-Energy Deposition Patents: Leaders & Trends 2026
Metal additive manufacturing patents in closed-loop directed-energy deposition
23.4% concentration at the top. The five leading assignees hold 1,812 of the 7,759 records in scope — a genuine lead cluster, not a monopoly. Filings ran from 671 in 2017 to a peak of 1,075 in 2019, and 2021 (820) to 2024 (718) shows a 12% decline over that span — the only period long enough past the ~18-month publication lag to read cleanly. 2025 and 2026 figures are still incomplete and should not be read as a continued drop.

Common questions about this landscape
Who holds the most patents in closed-loop directed-energy deposition for metal additive manufacturing?
The leading assignee holds 666 of the 7,759 records in scope, well ahead of the rest of the top five, which combined reach 1,812 records (23.4% of the field). That leader’s most-cited filings are orthodontic appliance patents rather than industrial metal parts, which is a reminder that a keyword-defined field like this one pulls in adjacent applications that share the same closed-loop deposition claim language. Industrial names such as General Electric, Boeing, BAE Systems and Divergent Technologies sit just behind in the top ten, which together account for 31.9% of all records.
Is patent filing in this field growing or slowing down?
Filings peaked at 1,075 in 2019 and the cleanest recent comparison — 2021 (820) to 2024 (718) — shows a 12% decline over three years. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by around 18 months, so they understate real activity and should not be read as a continued fall. The honest read is a plateau after a 2019 peak, not a clear downward trend.
Why do dental and orthodontic patents show up in a metal additive manufacturing search?
A61C (dentistry and oral hygiene) reaches 7.4% of the 7,759 records because aligner and appliance fabrication use the same closed-loop, layer-by-layer deposition and feedback-control claim language as metal directed-energy deposition, even though the end product is often a polymer aligner rather than a metal part. The leading assignee in this dataset built much of its portfolio in that overlap. Anyone scoping freedom-to-operate in industrial metal AM should check whether a blocking claim is actually aimed at dental applications before assuming it applies.
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.
