Does more volume mean deeper claims for Dorner?

Each dot is one of Dorner’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). Dorner’s own 16.9 claims/patent is ABOVE the 5.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dorner's grants concentrate

Dorner Mfg. Corp. is a focused PatentsView assignee: 1 CPC subclasses with 100% of grants classified under B65G (Transport OR Storage Devices, e.g. Conveyors FOR Loading OR Tipping, Shop Conveyor Systems OR Pneumatic Tube Conveyors). Peak complete grant year is 2023 (3 grants) versus a trough of 1 in 2015. By volume, Dorner sits between Dongguan City Kaihua Electronics Co., Ltd and Drivent LLC.

Dorner's three-year grant acceleration

Dorner Mfg. Corp. shows 5 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.
