What this shows Perstorp's Innovation Score is 42.4/100 (top 31% 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 Perstorp?

Each dot is one of Perstorp’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). Perstorp’s own 18.4 claims/patent is ABOVE the 16.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Perstorp's grants concentrate

Perstorp AB is a focused PatentsView assignee: 26 CPC subclasses with 26.3% of grants classified under C07C (Acyclic OR Carbocyclic Compounds). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2016. By volume, Perstorp sits between Pacid Technologies, LLC and Pluristem Ltd..

Perstorp's three-year grant acceleration

Perstorp AB shows 4 grants in 2022–2024 against only 9 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.
