What this shows Nissei's Innovation Score is 30.0/100 (33rd 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 Nissei?

Each dot is one of Nissei’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). Nissei’s own 8.3 claims/patent is at or below the 12.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Nissei's grants concentrate

Nissei Limited is a focused PatentsView assignee: 10 CPC subclasses with 42.9% of grants classified under H01Q (Antennas, i.e. Radio Aerials). Peak complete grant year is 2015 (2 grants) versus a trough of 1 in 2016. By volume, Nissei sits between Ningbo Aura Semiconductor Co., Ltd. and Noles Intellectual Properties, LLC.

Nissei's three-year grant acceleration

Nissei Limited shows 1 grants in 2022–2024 against only 1 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.
