What this shows Taimei's Innovation Score is 29.0/100 (29th 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 Taimei?

Each dot is one of Taimei’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). Taimei’s own 6.8 claims/patent is at or below the 19.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Taimei's grants concentrate

Taimei Chemicals Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 68.8% of grants classified under B24D (Tools FOR Grinding, Buffing OR Sharpening). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2016. By volume, Taimei sits between Syndicate Sales, Inc. and TE Connectivity Brasil Industria De Eletronicos Ltda..

Taimei's three-year grant acceleration

Taimei Chemicals Co., Ltd. shows 3 grants in 2022–2024 against only 7 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.
