What this shows NOV's Innovation Score is 51.9/100 (top 11% 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 15.6 claims/patent is ABOVE the 13.7 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 Canada ULC is a focused PatentsView assignee: 17 CPC subclasses with 66.7% 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 2022 (6 grants) versus a trough of 3 in 2023. By volume, NOV sits between Nobelpharma Co., Ltd. and Novogy, Inc..

NOV's three-year grant acceleration

NOV Canada ULC shows 9 grants in 2022–2024 against only 0 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.
