Each dot is one of Primetals’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). Primetals’s own 13.7 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2015. By volume, Primetals sits between Premier Energy Holdings, Inc. and Prionics AG.

Primetals's three-year grant acceleration

Primetals Technologies, Limited shows 1 grants in 2022–2024 against only 2 in 2019–2021. That prior window is too thin for a growth multiple (rename and spin-out assignees look artificially high when the baseline is near zero), so PlainPatent withholds a ranked acceleration claim here.
