Where Harper's grants concentrate

Harper Industries, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 50% of grants classified under A01D (HARVESTING; Mowing). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2016. By volume, Harper sits between Hankuk Carbon Co., Ltd. and Harvard Apparatus Regenerative Technology, Inc..

Harper's three-year grant acceleration

Harper Industries, Inc. shows 2 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.
