What this shows Nittoh'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 Nittoh?

Each dot is one of Nittoh’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). Nittoh’s own 13.8 claims/patent is ABOVE the 12.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Nittoh's grants concentrate

Nittoh Inc. is a focused PatentsView assignee: 4 CPC subclasses with 97.4% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2019 (7 grants) versus a trough of 2 in 2017. By volume, Nittoh sits between Netradyne, Inc. and NuWave LLC.

Nittoh's three-year grant acceleration

Nittoh Inc. shows 11 grants in 2022–2024 against only 19 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.
