Does more volume mean deeper claims for Sogefi?
Each dot is one of Sogefi’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). Sogefi’s own 16.7 claims/patent is ABOVE the 15.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Sogefi's grants concentrate
Sogefi Filtration is a focused PatentsView assignee: 10 CPC subclasses with 55.6% of grants classified under B01D (Separation). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2016. By volume, Sogefi sits between Snapaid Ltd. and Solteam Electronics (DONG GUAN) Co., Ltd..
Sogefi's three-year grant acceleration
Sogefi Filtration 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.
