What this shows Stiebel's Innovation Score is 38.0/100 (top 42% 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 Stiebel?

Each dot is one of Stiebel’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). Stiebel’s own 9.2 claims/patent is at or below the 16.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Stiebel's grants concentrate

Stiebel Eltron GMBH & Co. KG is a focused PatentsView assignee: 17 CPC subclasses with 66.7% of grants classified under F24H (Fluid Heaters, e.g. Water OR AIR Heaters, Having Heat-generating Means, e.g. Heat Pumps, IN General). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2021. By volume, Stiebel sits between Sphingotec GMBH and Surface Generation Limited.

Stiebel's three-year grant acceleration

Stiebel Eltron GMBH & Co. KG shows 7 grants in 2022–2024 against only 6 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.
