What this shows NS's Innovation Score is 40.3/100 (top 36% 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 NS?

Each dot is one of NS’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). NS’s own 9.8 claims/patent is ABOVE the 8.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where NS's grants concentrate

NS Materials Inc. is a focused PatentsView assignee: 28 CPC subclasses with 70.8% of grants classified under H10H (Inorganic Light-emitting Semiconductor Devices Having Potential Barriers). Peak complete grant year is 2020 (7 grants) versus a trough of 1 in 2017. By volume, NS sits between Nisshin Seifun Group Inc. and Navitar Industries, LLC.

NS's three-year grant acceleration

NS Materials Inc. shows 9 grants in 2022–2024 against only 13 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.
