What this shows Dr.'s Innovation Score is 25.7/100 (18th 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 Dr.?

Each dot is one of Dr.’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). Dr.’s own 12.1 claims/patent is at or below the 12.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Dr.'s grants concentrate

DR. Herfeld GMBH & Co. KG is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under B01F (Mixing, e.g. Dissolving, Emulsifying OR Dispersing). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2015. By volume, Dr. sits between Dorst Technologies GMBH & Co. KG and Dryip, LLC.

Dr.'s three-year grant acceleration

DR. Herfeld GMBH & Co. KG 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.
