Pyrogenesis mentioned in article on Ti powders. Look about a third of the way down the page.

GE Aviation and ATI developing meltless titanium alloy powder manufacturing technology for 3D printing

It's generally accepted that Pyrogenesis "patented" plasma atomization. I accept that Pegasus Refractory Metals is the original assignee and the patent was reassigned to Pyrogenesis via a merger. In the day of "corporations are people" what Pyrogenesis claims sounds too much like - Hedy Lamarr's patent for jamming resistant radio guidance for torpedoes, but the patent is attributed to John Loder because they married after the patent assignment to Hedy.

In the patent application below they describe modifications that improve powder production capacity. This is all Pyrogenesis work. This appears to be what they're on about with recent plans to industrialize powder production.

Plasma apparatus for the production of high quality spherical powders at high capacity

If this allows high quality production of powder at lower prices than the main competition at AP&C, who produces "an estimated 70% of the metal powder used in additive manufacturing," they're really onto something. GE's recent joint venture with ATI is all about economizing powder production.
