What this shows Rotarex's Innovation Score is 51.4/100 (top 11% 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 Rotarex?

Each dot is one of Rotarex’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). Rotarex’s own 18.0 claims/patent is ABOVE the 11.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Rotarex's grants concentrate

Rotarex S.A. is a focused PatentsView assignee: 11 CPC subclasses with 58.3% of grants classified under F17C (Vessels FOR Containing OR Storing Compressed, Liquefied OR Solidified GASES; Fixed-capacity GAS-HOLDERS; Filling Vessels With, OR Discharging From Vessels, Compressed, Liquefied, OR Solidified Gases). Peak complete grant year is 2022 (5 grants) versus a trough of 2 in 2024. By volume, Rotarex sits between Rocks OFF Limited and Ransburg Industrial Finishing K.K..

Rotarex's three-year grant acceleration

Rotarex S.A. shows 12 grants in 2022–2024 against only 0 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.
