What this shows DET's Innovation Score is 42.3/100 (top 31% 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 DET's grants concentrate

DET International Holding Limited is a focused PatentsView assignee: 27 CPC subclasses with 62.9% 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 2016 (9 grants) versus a trough of 1 in 2021. By volume, DET sits between Danby Products Limited and Epiroc Rock Drills Aktiebolag.

DET's three-year grant acceleration

DET International Holding Limited shows 2 grants in 2022–2024 against only 6 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.
