What this shows Rotex's Innovation Score is 43.5/100 (top 28% 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 Rotex?

Each dot is one of Rotex’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). Rotex’s own 15.6 claims/patent is ABOVE the 12.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Rotex's grants concentrate

Rotex Automation Limited is a focused PatentsView assignee: 15 CPC subclasses with 57.1% of grants classified under F02M (Supplying Combustion Engines IN General With Combustible Mixtures OR Constituents Thereof). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2018. By volume, Rotex sits between Rontgen Technische Dienst B.V. and Ruhrpumpen GmbH.

Rotex's three-year grant acceleration

Rotex Automation Limited shows 4 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.
