Does more volume mean deeper claims for Purestream?
Each dot is one of Purestream’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). Purestream’s own 21.1 claims/patent is ABOVE the 18.2 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Purestream's grants concentrate
Purestream Services, LLC is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under B01D (Separation). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2017. By volume, Purestream sits between Prysm Systems, Inc. and QFO Labs, Inc..
Purestream's three-year grant acceleration
Purestream Services, LLC shows 2 grants in 2022–2024 against only 2 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.
