What this shows Power's Innovation Score is 38.1/100 (top 42% 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 Power?

Each dot is one of Power’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). Power’s own 10.9 claims/patent is at or below the 11.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Power's grants concentrate

Power Forest Technology Corporation is a focused PatentsView assignee: 13 CPC subclasses with 83.7% 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 2015 (8 grants) versus a trough of 1 in 2020. By volume, Power sits between Oupiin ELECTRONIC(KUNSHAN) Co., Ltd and Radiometer Medical APS.

Power's three-year grant acceleration

Power Forest Technology Corporation shows 6 grants in 2022–2024 against only 7 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.
