What this shows NEC's Innovation Score is 32.0/100 (40th 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 NEC?

Each dot is one of NEC’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). NEC’s own 9.7 claims/patent is ABOVE the 9.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where NEC's grants concentrate

NEC Network and Sensor Systems, Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 66.7% of grants classified under H01J (Electric Discharge Tubes OR Discharge Lamps). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2015. By volume, NEC sits between Nachi-fujikoshi Corp. and Ningbo Weie Electronics Technology Ltd..

NEC's three-year grant acceleration

NEC Network and Sensor Systems, Ltd. shows 7 grants in 2022–2024 against only 7 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.
