Does more volume mean deeper claims for Harper?

Each dot is one of Harper’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). Harper’s own 15.0 claims/patent is ABOVE the 13.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

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.
