Where BEL's grants concentrate

BEL Power Solutions Inc. is a focused PatentsView assignee: 11 CPC subclasses with 50% of grants classified under H02M (APPARATUS FOR CONVERSION BETWEEN AC AND AC, BETWEEN AC AND DC, OR BETWEEN DC AND DC, AND FOR USE WITH MAINS OR SIMILAR POWER SUPPLY SYSTEMS; CONVERSION OF DC OR AC INPUT POWER INTO SURGE OUTPUT POWER;). Peak complete grant year is 2018 (5 grants) versus a trough of 1 in 2023. By volume, BEL sits between Beijing Nufront Mobile Multimedia Technology Co. Ltd. and Beyond Trust Software, Inc..

BEL's three-year grant acceleration

BEL Power Solutions Inc. shows 1 grants in 2022–2024 against only 2 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.
