What this shows Kringstad's Innovation Score is 43.8/100 (top 27% 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 Kringstad?

Each dot is one of Kringstad’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). Kringstad’s own 17.4 claims/patent is ABOVE the 15.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Kringstad's grants concentrate

Kringstad Ironworks, Inc. is a focused PatentsView assignee: 3 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 2022 (2 grants) versus a trough of 1 in 2020. By volume, Kringstad sits between Koike Sanso Kogyo Co., Ltd. and Kumquat Biosciences Inc..

Kringstad's three-year grant acceleration

Kringstad Ironworks, Inc. shows 4 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.
