What this shows Erwin's Innovation Score is 48.3/100 (top 17% 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 Erwin?

Each dot is one of Erwin’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). Erwin’s own 20.2 claims/patent is ABOVE the 16.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Erwin's grants concentrate

Erwin Quarder Systemtechnik GMBH is a focused PatentsView assignee: 8 CPC subclasses with 80% of grants classified under H01L (Semiconductor Devices NOT Covered BY Class H10). Peak complete grant year is 2024 (4 grants) versus a trough of 1 in 2022. By volume, Erwin sits between Equus UK Topco Ltd and Esta Apparatebau GMBH & Co. KG.

Erwin's three-year grant acceleration

Erwin Quarder Systemtechnik GMBH shows 5 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.
