What this shows Sejin-igb's Innovation Score is 37.1/100 (top 44% of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Where Sejin-igb's grants concentrate

Sejin-igb Co., Ltd. is a focused PatentsView assignee: 14 CPC subclasses with 81.8% of grants classified under F16H (GEARING). Peak complete grant year is 2022 (4 grants) versus a trough of 1 in 2015. By volume, Sejin-igb sits between Sciperio, Inc and SEN Corporation.

Sejin-igb's three-year grant acceleration

Sejin-igb Co., Ltd. shows 4 grants in 2022–2024 against only 4 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.
