What this shows Nihon's Innovation Score is 34.1/100 (46th 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 Nihon?

Each dot is one of Nihon’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). Nihon’s own 7.6 claims/patent is at or below the 8.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nihon's grants concentrate

Nihon Nohyaku Co., Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 84.6% of grants classified under C07D (Heterocyclic Compounds). Peak complete grant year is 2015 (10 grants) versus a trough of 1 in 2023. By volume, Nihon sits between MiRus LLC and Outbrain Inc..

Nihon's three-year grant acceleration

Nihon Nohyaku Co., Ltd. shows 8 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.
