Does more volume mean deeper claims for Downing?
Each dot is one of Downing’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). Downing’s own 27.2 claims/patent is ABOVE the 17.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Downing's grants concentrate
Downing Wellhead Equipment, LLC is a focused PatentsView assignee: 4 CPC subclasses with 93.1% 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 (7 grants) versus a trough of 4 in 2021. By volume, Downing sits between DePuy International Limited and Enswers Co., Ltd..
Downing's three-year grant acceleration
Downing Wellhead Equipment, LLC shows 17 grants in 2022–2024 against only 10 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.
