What this shows Bilstein's Innovation Score is 41.9/100 (top 32% 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 Bilstein?

Each dot is one of Bilstein’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). Bilstein’s own 14.3 claims/patent is ABOVE the 13.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Bilstein's grants concentrate

Bilstein GMBH & Co. KG is a focused PatentsView assignee: 14 CPC subclasses with 66.7% of grants classified under C21D (Modifying THE Physical Structure OF Ferrous METALS; General Devices FOR Heat Treatment OF Ferrous OR Non-ferrous Metals OR ALLOYS; Making Metal Malleable, e.g. BY Decarburisation OR Tempering). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2015. By volume, Bilstein sits between Biax-fiberfilm Corporation and Bio-medical Research Ltd.

Bilstein's three-year grant acceleration

Bilstein GMBH & Co. KG shows 2 grants in 2022–2024 against only 1 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.
