What this shows Durex's Innovation Score is 30.0/100 (33rd 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 Durex?

Each dot is one of Durex’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). Durex’s own 10.0 claims/patent is at or below the 16.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Durex's grants concentrate

Durex International Corp. is a focused PatentsView assignee: 9 CPC subclasses with 66.7% of grants classified under H05B (Electric HEATING; Electric Light Sources NOT Otherwise Provided FOR; Circuit Arrangements FOR Electric Light Sources, IN General). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2019. By volume, Durex sits between Drive Foods Corp and Dynamic Shelters Inc..

Durex's three-year grant acceleration

Durex International Corp. shows 1 grants in 2022–2024 against only 1 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.
