What this shows Kiefel's Innovation Score is 41.2/100 (top 34% 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 Kiefel?

Each dot is one of Kiefel’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). Kiefel’s own 18.1 claims/patent is ABOVE the 12.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kiefel's grants concentrate

Kiefel GMBH is a focused PatentsView assignee: 21 CPC subclasses with 86.4% of grants classified under B29C (Shaping OR Joining OF PLASTICS; Shaping OF Material IN A Plastic State, NOT Otherwise Provided FOR; After-treatment OF THE Shaped Products, e.g. Repairing). Peak complete grant year is 2020 (5 grants) versus a trough of 1 in 2015. By volume, Kiefel sits between Johnson Controls Light Commercial IP GmbH and Kyonggi University Industry & Academia Cooperation Foundation.

Kiefel's three-year grant acceleration

Kiefel GMBH shows 5 grants in 2022–2024 against only 10 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.
