What this shows Nippon's Innovation Score is 34.2/100 (47th 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 9.4 claims/patent is at or below the 10.3 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 Yusen Kabushiki Kaisha is a focused PatentsView assignee: 18 CPC subclasses with 100% of grants classified under B63B (Ships OR Other Waterborne VESSELS; Equipment FOR Shipping). Peak complete grant year is 2018 (3 grants) versus a trough of 1 in 2017. By volume, Nippon sits between Ningbo Yamao Optoelectronics Co., Ltd. and Northstar Battery Company, LLC.

Nippon's three-year grant acceleration

Nippon Yusen Kabushiki Kaisha shows 3 grants in 2022–2024 against only 4 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.
