What this shows P-duke's Innovation Score is 43.9/100 (top 27% 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.

Does more volume mean deeper claims for P-duke?

Each dot is one of P-duke’s 8 nearest volume peers (same corpus rank neighbourhood as the chart above), placed by total granted patents (horizontal) against average claims per patent (vertical). P-duke’s own 9.9 claims/patent is at or below the 17.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where P-duke's grants concentrate

P-duke Technology Co., Ltd. is a focused PatentsView assignee: 8 CPC subclasses with 66.7% 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 2023 (3 grants) versus a trough of 1 in 2022. By volume, P-duke sits between Owl Cyber Defense Solutions, LLC and PAN Pacific Copper Co., Ltd..

P-duke's three-year grant acceleration

P-duke Technology Co., Ltd. shows 6 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.
