What this shows Nansin's Innovation Score is 31.3/100 (37th percentile 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 Nansin?

Each dot is one of Nansin’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). Nansin’s own 7.8 claims/patent is at or below the 9.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nansin's grants concentrate

Nansin Co., Ltd. is a focused PatentsView assignee: 4 CPC subclasses with 80% of grants classified under B60B (Vehicle Wheels ; CASTORS; Axles FOR Wheels OR CASTORS; Increasing Wheel Adhesion). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2019. By volume, Nansin sits between Nanomakers and National Chemical Company LLC.

Nansin's three-year grant acceleration

Nansin Co., Ltd. shows 2 grants in 2022–2024 against only 1 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.
