Does more volume mean deeper claims for SPF?
Each dot is one of SPF’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). SPF’s own 19.3 claims/patent is ABOVE the 16.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where SPF's grants concentrate
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's three-year grant acceleration
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.
