What this shows Channel's Innovation Score is 44.6/100 (top 25% 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 Channel's grants concentrate

Channel Well Technology Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 33.3% 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 2022 (5 grants) versus a trough of 1 in 2018. By volume, Channel sits between Chang Gung Biotechnology Corp. and Chaun-choung Technology Corp..

Channel's three-year grant acceleration

Channel Well Technology Co., Ltd. shows 5 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.
