What this shows A.'s Innovation Score is 36.5/100 (top 46% 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 A.?

Each dot is one of A.’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). A.’s own 15.1 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where A.'s grants concentrate

A. Kayser Automotive Systems GmbH is a focused PatentsView assignee: 13 CPC subclasses with 35.7% of grants classified under F02M (Supplying Combustion Engines IN General With Combustible Mixtures OR Constituents Thereof). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2017. By volume, A. sits between 1ahead Technologies and AB Volvo Penta.

A.'s three-year grant acceleration

A. Kayser Automotive Systems GmbH shows 4 grants in 2022–2024 against only 5 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.
