What this shows Nidec's Innovation Score is 38.4/100 (top 41% 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 Nidec?

Each dot is one of Nidec’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). Nidec’s own 8.3 claims/patent is at or below the 10.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nidec's grants concentrate

Nidec Servo Corporation is a focused PatentsView assignee: 21 CPC subclasses with 44.4% of grants classified under H02K (Dynamo-electric Machines). Peak complete grant year is 2021 (8 grants) versus a trough of 1 in 2015. By volume, Nidec sits between Mortarless Technologies, LLC and Nordex Energy GmbH.

Nidec's three-year grant acceleration

Nidec Servo Corporation shows 10 grants in 2022–2024 against only 14 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.
