What this shows NOX's Innovation Score is 33.9/100 (46th 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 NOX?

Each dot is one of NOX’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). NOX’s own 17.0 claims/patent is ABOVE the 11.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where NOX's grants concentrate

NOX II, Ltd. is a focused PatentsView assignee: 12 CPC subclasses with 100% of grants classified under C10L (Fuels NOT Otherwise Provided FOR; Natural GAS; Synthetic Natural GAS Obtained BY Processes NOT Covered BY Subclasses C10g OR C10K; Liquified Petroleum GAS; USE OF Additives TO Fuels OR FIRES; Fire-lig). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2016. By volume, NOX sits between Nippon Carbide Industries Co., Inc. and NanoXplore Inc..

NOX's three-year grant acceleration

NOX II, Ltd. shows 2 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.
