What this shows Nippon's Innovation Score is 20.6/100 (7th 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 Nippon?

Each dot is one of Nippon’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). Nippon’s own 7.8 claims/patent is at or below the 12.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nippon's grants concentrate

Nippon Tanshi Co., Ltd. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under H01R (Electrically-conductive CONNECTIONS; Structural Associations OF A Plurality OF Mutually-insulated Electrical Connecting ELEMENTS; Coupling DEVICES; Current Collectors). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2018. By volume, Nippon sits between NewPace Ltd. and Norell, Inc..

Nippon's three-year grant acceleration

Nippon Tanshi Co., Ltd. shows 1 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.
