What this shows Teco's Innovation Score is 39.2/100 (top 39% 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 Teco?

Each dot is one of Teco’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). Teco’s own 7.7 claims/patent is at or below the 12.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Teco's grants concentrate

Teco Electric & Machinery Co., Ltd. is a focused PatentsView assignee: 21 CPC subclasses with 52.2% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2022 (7 grants) versus a trough of 1 in 2020. By volume, Teco sits between TABOOLA.COM Ltd. and THE Chemo-sero-therapeutic Research Institute.

Teco's three-year grant acceleration

Teco Electric & Machinery Co., Ltd. shows 10 grants in 2022–2024 against only 9 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.
