What this shows Universität's Innovation Score is 44.1/100 (top 27% 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 Universität?

Each dot is one of Universität’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). Universität’s own 12.5 claims/patent is at or below the 14.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Universität's grants concentrate

UNIVERSITÄT Duisburg-essen is a focused PatentsView assignee: 37 CPC subclasses with 36% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2015 (6 grants) versus a trough of 1 in 2020. By volume, Universität sits between Universita' Degli Studi DI Milano - Bicocca and Universidade Federal Do Rio Grande Do Sul—UFRGS.

Universität's three-year grant acceleration

UNIVERSITÄT Duisburg-essen shows 4 grants in 2022–2024 against only 7 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.
