What this shows Heerema's Innovation Score is 43.2/100 (top 29% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for Heerema?

Each dot is one of Heerema’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). Heerema’s own 16.6 claims/patent is ABOVE the 10.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Heerema's grants concentrate

Heerema Marine Contractors Nederland SE is a focused PatentsView assignee: 15 CPC subclasses with 52.4% of grants classified under B63B (Ships OR Other Waterborne VESSELS; Equipment FOR Shipping). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2019. By volume, Heerema sits between Huizhou Kimree Technology Co., Ltd. and Hoerbiger Kompressortechnik Holding GmbH.

Heerema's three-year grant acceleration

Heerema Marine Contractors Nederland SE shows 4 grants in 2022–2024 against only 3 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.
