What this shows NOV's Innovation Score is 34.6/100 (48th 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 NOV?

Each dot is one of NOV’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). NOV’s own 17.8 claims/patent is ABOVE the 13.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where NOV's grants concentrate

NOV Process & Flow Technologies US, Inc. is a focused PatentsView assignee: 13 CPC subclasses with 50% of grants classified under B01D (Separation). Peak complete grant year is 2022 (2 grants) versus a trough of 1 in 2019. By volume, NOV sits between North American Specialty Products LLC and Novum Engineering GMBH.

NOV's three-year grant acceleration

NOV Process & Flow Technologies US, Inc. shows 2 grants in 2022–2024 against only 3 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.
