What this shows Natural's Innovation Score is 49.1/100 (top 15% 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 Natural?

Each dot is one of Natural’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). Natural’s own 17.7 claims/patent is ABOVE the 11.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Natural's grants concentrate

Natural Ocean Well Co. is a focused PatentsView assignee: 7 CPC subclasses with 69.2% of grants classified under Y02A (Technologies FOR Adaptation TO Climate Change). Peak complete grant year is 2022 (5 grants) versus a trough of 1 in 2021. By volume, Natural sits between Nanhu Laboratory and Neptune Benson, Inc..

Natural's three-year grant acceleration

Natural Ocean Well Co. shows 12 grants in 2022–2024 against only 1 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.
