What this shows Karcher's Innovation Score is 33.6/100 (45th percentile 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 Karcher?

Each dot is one of Karcher’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). Karcher’s own 10.2 claims/patent is at or below the 12.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Karcher's grants concentrate

Karcher North America, Inc. is a focused PatentsView assignee: 13 CPC subclasses with 41.2% of grants classified under A47L (Domestic Washing OR Cleaning ; Suction Cleaners IN General). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2016. By volume, Karcher sits between KSi Conveyor, Inc. and Kilpatrick Townsend & Stockton LLP.

Karcher's three-year grant acceleration

Karcher North America, Inc. shows 5 grants in 2022–2024 against only 7 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.
