What this shows NOV's Innovation Score is 37.2/100 (top 44% 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 25.6 claims/patent is ABOVE the 7.7 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 Downhole Eurasia Limited is a focused PatentsView assignee: 8 CPC subclasses with 95.8% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2018 (9 grants) versus a trough of 1 in 2019. By volume, NOV sits between Nickolas Brands, LLC and Natus Medical Incorporated.

NOV's three-year grant acceleration

NOV Downhole Eurasia Limited shows 1 grants in 2022–2024 against only 6 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.
