What this shows Otto's Innovation Score is 45.5/100 (top 23% 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 Otto?

Each dot is one of Otto’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). Otto’s own 16.6 claims/patent is ABOVE the 11.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Otto's grants concentrate

Otto Egelhof GmbH & Co. KG is a focused PatentsView assignee: 9 CPC subclasses with 100% of grants classified under F16K (VALVES; TAPS; COCKS; ACTUATING-FLOATS; Devices FOR Venting OR Aerating). Peak complete grant year is 2023 (4 grants) versus a trough of 1 in 2017. By volume, Otto sits between Orange Electronic Co., Ltd and Odyssey Wireless, Inc..

Otto's three-year grant acceleration

Otto Egelhof GmbH & Co. KG shows 7 grants in 2022–2024 against only 3 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.
