What this shows Nippon's Innovation Score is 50.7/100 (top 12% 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 10.1 claims/patent is at or below the 14.1 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 Chemical Industrial Co., Ltd. is a focused PatentsView assignee: 40 CPC subclasses with 41.7% of grants classified under C01P (Indexing Scheme Relating TO Structural AND Physical Aspects OF Solid Inorganic Compounds). Peak complete grant year is 2022 (12 grants) versus a trough of 2 in 2017. By volume, Nippon sits between Microsemi Semiconductor ULC and Neapco Intellectual Property Holdings, LLC.
Nippon's three-year grant acceleration
Nippon Chemical Industrial Co., Ltd. shows 20 grants in 2022–2024 against only 15 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.
