What this shows Kienle's Innovation Score is 29.6/100 (31st 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 Kienle?

Each dot is one of Kienle’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). Kienle’s own 10.5 claims/patent is ABOVE the 9.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kienle's grants concentrate

Kienle + Spiess GmbH is a focused PatentsView assignee: 11 CPC subclasses with 100% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2016. By volume, Kienle sits between Kabushiki Kaisha Takai Rika Denki Seisakusho and Klipsch Group, Inc..

Kienle's three-year grant acceleration

Kienle + Spiess GmbH shows 3 grants in 2022–2024 against only 8 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.
