What this shows Semperit's Innovation Score is 33.0/100 (43rd 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 Semperit?

Each dot is one of Semperit’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). Semperit’s own 15.4 claims/patent is ABOVE the 12.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Semperit's grants concentrate

Semperit Aktiengesellschaft Holding is a focused PatentsView assignee: 14 CPC subclasses with 71.4% of grants classified under C08J (WORKING-UP; General Processes OF COMPOUNDING; After-treatment NOT Covered BY Subclasses C08b, C08c, C08f, C08g or C08h). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2019. By volume, Semperit sits between Seleggt GmbH and Seppi M. SPA AG.

Semperit's three-year grant acceleration

Semperit Aktiengesellschaft Holding shows 1 grants in 2022–2024 against only 2 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.
