What this shows Dartpoint's Innovation Score is 39.4/100 (top 38% 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 Dartpoint?

Each dot is one of Dartpoint’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). Dartpoint’s own 18.5 claims/patent is ABOVE the 15.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Dartpoint's grants concentrate

Dartpoint Tech. Co., Ltd. is a focused PatentsView assignee: 24 CPC subclasses with 50% of grants classified under A61H (Physical Therapy Apparatus, e.g. Devices FOR Locating OR Stimulating Reflex Points IN THE BODY; Artificial RESPIRATION; MASSAGE; Bathing Devices FOR Special Therapeutic OR Hygienic Purposes OR Specifi). Peak complete grant year is 2021 (4 grants) versus a trough of 1 in 2020. By volume, Dartpoint sits between Daito Giken, Inc. and Delta AIR Lines, Inc..

Dartpoint's three-year grant acceleration

Dartpoint Tech. Co., Ltd. shows 2 grants in 2022–2024 against only 8 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.
