What this shows SPF's Innovation Score is 41.3/100 (top 34% 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.
SPF Technologies Llc is a focused PatentsView assignee: 8 CPC subclasses with 100% of grants classified under B01D (SEPARATION). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2016. By volume, SPF sits between Sondex Wireline Limited and SSW Advanced Technologies, Llc.
SPF Technologies Llc shows 5 grants in 2022–2024 against only 3 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.
