What this shows Hesai's Innovation Score is 54.5/100 (top 8% 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 Hesai?

Each dot is one of Hesai’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). Hesai’s own 13.9 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Hesai's grants concentrate

Hesai Technology Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 66.7% of grants classified under G01S (Radio DIRECTION-FINDING; Radio NAVIGATION; Determining Distance OR Velocity BY USE OF Radio WAVES; Locating OR Presence-detecting BY USE OF THE Reflection OR Reradiation OF Radio WAVES; Analogous Arra). Peak complete grant year is 2024 (15 grants) versus a trough of 6 in 2021. By volume, Hesai sits between Hsio Technologies, LLC and Inpex Corporation.

Hesai's three-year grant acceleration

Hesai Technology Co., Ltd. shows 28 grants in 2022–2024 against only 6 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.
