Harper’s own 5.2 claims/patent is at or below the 14.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Harper's grants concentrate

Harper Trucks, Inc. is a focused PatentsView assignee: 1 CPC subclasses with 100% of grants classified under B62B (Hand-propelled Vehicles, e.g. Hand Carts OR PERAMBULATORS; Sledges). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2022. By volume, Harper sits between Hanwang Technology Co., Ltd. and Harvest Moon Automation Inc..

Harper's three-year grant acceleration

Harper Trucks, Inc. shows 2 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.
