What this shows Nirec's Innovation Score is 38.2/100 (top 41% 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 Nirec?

Each dot is one of Nirec’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). Nirec’s own 11.7 claims/patent is ABOVE the 7.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nirec's grants concentrate

Nirec Corporation is a focused PatentsView assignee: 10 CPC subclasses with 33.3% of grants classified under B22D (Casting OF METALS; Casting OF Other Substances BY THE Same Processes OR Devices). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2022. By volume, Nirec sits between Nippoh Chemicals Co., Ltd. and Nittoh Kogaku K.K..

Nirec's three-year grant acceleration

Nirec Corporation shows 2 grants in 2022–2024 against only 0 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.
