Where Sixring's grants concentrate

Sixring Inc. is a focused PatentsView assignee: 12 CPC subclasses with 100% of grants classified under D21C (Production OF Cellulose BY Removing Non-cellulose Substances From Cellulose-containing MATERIALS; Regeneration OF Pulping LIQUORS; Apparatus Therefor). Peak complete grant year is 2024 (10 grants) versus a trough of 4 in 2023. By volume, Sixring sits between Shenzhen Kanger Technology Co., Ltd and State Grid Jiangsu Electric Power Research Institute.

Sixring's three-year grant acceleration

Sixring Inc. shows 14 grants in 2022–2024 against only 0 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.
