What this shows STL's Innovation Score is 25.1/100 (16th percentile 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 STL's grants concentrate

STL Technology Co., Ltd. is a focused PatentsView assignee: 7 CPC subclasses with 50% of grants classified under H01M (Processes OR Means, e.g. Batteries, FOR THE Direct Conversion OF Chemical Energy Into Electrical Energy). Peak complete grant year is 2021 (3 grants) versus a trough of 1 in 2020. By volume, STL sits between Sticnstac LLC and Stormtech LLC.

STL's three-year grant acceleration

STL Technology Co., Ltd. shows 2 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.
