Does more volume mean deeper claims for National?

Each dot is one of National’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). National’s own 19.6 claims/patent is ABOVE the 11.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where National's grants concentrate

National Oilwell Vareo, L.P. is a focused PatentsView assignee: 7 CPC subclasses with 60% 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 2021 (4 grants) versus a trough of 1 in 2022. By volume, National sits between Nanotronics Health, LLC. and NatureWise Biotech & Medicals Corporation.

National's three-year grant acceleration

National Oilwell Vareo, L.P. shows 1 grants in 2022–2024 against only 4 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.
