What this shows ADC's Innovation Score is 40.4/100 (top 36% 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 ADC?

Each dot is one of ADC’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). ADC’s own 20.6 claims/patent is ABOVE the 18.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where ADC's grants concentrate

ADC Therapeutics SA is a focused PatentsView assignee: 6 CPC subclasses with 100% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2017. By volume, ADC sits between Abberior Instruments GMBH and Alcyone Lifesciences, Inc..

ADC's three-year grant acceleration

ADC Therapeutics SA shows 9 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.
