What this shows Nittan's Innovation Score is 42.9/100 (top 29% 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 Nittan?

Each dot is one of Nittan’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). Nittan’s own 7.2 claims/patent is at or below the 14.4 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nittan's grants concentrate

Nittan Valve Co., Ltd. is a focused PatentsView assignee: 42 CPC subclasses with 75% of grants classified under F01L (Cyclically Operating Valves FOR Machines OR Engines). Peak complete grant year is 2015 (14 grants) versus a trough of 2 in 2018. By volume, Nittan sits between Moskowitz Family LLC and Respivert Ltd..

Nittan's three-year grant acceleration

Nittan Valve Co., Ltd. shows 4 grants in 2022–2024 against only 16 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.
