What this shows Phihong's Innovation Score is 42.9/100 (top 29% 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 Phihong?

Each dot is one of Phihong’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). Phihong’s own 14.5 claims/patent is at or below the 17.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Phihong's grants concentrate

Phihong Technology Co., Ltd. is a focused PatentsView assignee: 22 CPC subclasses with 35.7% of grants classified under H02J (Circuit Arrangements OR Systems FOR Supplying OR Distributing Electric POWER; Systems FOR Storing Electric Energy). Peak complete grant year is 2019 (5 grants) versus a trough of 1 in 2016. By volume, Phihong sits between Opel Solar, Inc. and Panzura LLC.

Phihong's three-year grant acceleration

Phihong Technology Co., Ltd. shows 9 grants in 2022–2024 against only 10 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.
