Where Sparrow's grants concentrate

Sparrow Co., Ltd is a focused PatentsView assignee: 2 CPC subclasses with 66.7% of grants classified under G06F (Electric Digital Data Processing). Peak complete grant year is 2019 (3 grants) versus a trough of 1 in 2022. By volume, Sparrow sits between Southeastern Metals Manufacturing Co. Inc. and SPF Innovations, LLC.

Sparrow's three-year grant acceleration

Sparrow Co., Ltd shows 2 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.
