What this shows Nippon's Innovation Score is 41.8/100 (top 32% 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 9.8 claims/patent is at or below the 10.8 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 Steel Engineering Co., Ltd is a focused PatentsView assignee: 27 CPC subclasses with 54.5% of grants classified under C10G (Cracking Hydrocarbon OILS; Production OF Liquid Hydrocarbon Mixtures, e.g. BY Destructive Hydrogenation, Oligomerisation, Polymerisation ; Recovery OF Hydrocarbon Oils From Oil-shale, Oil-sand, OR GAS). Peak complete grant year is 2015 (8 grants) versus a trough of 1 in 2018. By volume, Nippon sits between Newlight Technologies, Inc. and Nan Juen International Co., Ltd..

Nippon's three-year grant acceleration

Nippon Steel Engineering Co., Ltd shows 4 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.
