Within this 26-record scope, one assignee leads with 9 records, roughly a third of the whole dataset. The ranking covers five assignees in total, and combined they account for 100.0% of all 26 records in scope, meaning there is no unranked long tail of outside filers in this specific search. That said, the search terms are narrow — a broader query on general aerospace additive manufacturing would likely surface more entrants.

In this dataset, claims cluster most heavily around combustion chamber design (F23R, 57.7% of records) and powder metallurgy process steps (B22F, 50.0%), rather than the additive manufacturing method alone (B33Y, 23.1%). That pattern means the strongest claims tend to combine a specific part geometry or joint design with a printing or post-processing step, not a generic ‘print this part’ method. Reviewing the representative filing on machined-surface additive builds is a reasonable starting point for understanding how these claims are typically structured.

The visible trend shows a peak of 7 records in 2019 followed by lower counts, including zero in the most recent year across every ranked assignee. However, patent publication typically lags actual filing by about 18 months, so recent-year figures are understated by default rather than necessarily reflecting reduced R&D activity. A meaningful growth rate cannot be computed from the available complete years, so any slowdown claim should be treated as provisional until later data confirms it.
