Does more volume mean deeper claims for Donaldson?

Each dot is one of Donaldson’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). Donaldson’s own 14.0 claims/patent is ABOVE the 8.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Donaldson's grants concentrate

Donaldson Filtration Deutschland GmbH is a focused PatentsView assignee: 5 CPC subclasses with 100% of grants classified under B01D (Separation). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2021. By volume, Donaldson sits between Doctor Optics SE and Dongguan Bluefinger Electronics Co., Limited.

Donaldson's three-year grant acceleration

Donaldson Filtration Deutschland GmbH shows 1 grants in 2022–2024 against only 3 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.
