Where Sirbal's grants concentrate

Sirbal Limited is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2017 (5 grants) versus a trough of 1 in 2020. By volume, Sirbal sits between Silver State Intellectual Technologies, Inc. and Skybest Electric Appliance (Suzhou) Co., Ltd..

Sirbal's three-year grant acceleration

Sirbal Limited shows 1 grants in 2022–2024 against only 1 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.
