Where Hsin's grants concentrate

Hsin Chong Machinery Works Co. Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 55.6% of grants classified under B60J (Windows, Windscreens, Non-fixed Roofs, Doors, OR Similar Devices FOR VEHICLES; Removable External Protective Coverings Specially Adapted FOR Vehicles). Peak complete grant year is 2023 (2 grants) versus a trough of 1 in 2016. By volume, Hsin sits between Hong International Corporation and Human Genome Sciences, Inc..

Hsin's three-year grant acceleration

Hsin Chong Machinery Works Co. Ltd. shows 3 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.
