What this shows HBL's Innovation Score is 45.6/100 (top 23% 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 HBL's grants concentrate

HBL Corporation is a focused PatentsView assignee: 11 CPC subclasses with 42.9% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2017. By volume, HBL sits between Harumoto Technology (SHEN ZHEN) Co., Ltd. and Hefei JEE Power Systems Co., Ltd..

HBL's three-year grant acceleration

HBL Corporation 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.
