What this shows White's Innovation Score is 42.4/100 (top 31% 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 White?

Each dot is one of White’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). White’s own 19.5 claims/patent is ABOVE the 14.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where White's grants concentrate

White Knight Fluid Handling, Inc. is a focused PatentsView assignee: 14 CPC subclasses with 69.2% of grants classified under F04B (Positive-displacement Machines FOR LIQUIDS; Pumps). Peak complete grant year is 2018 (4 grants) versus a trough of 2 in 2019. By volume, White sits between Wearwell, LLC and WorldViz, Inc..

White's three-year grant acceleration

White Knight Fluid Handling, Inc. shows 5 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.
