What this shows Phoenix's Innovation Score is 37.5/100 (top 43% 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 Phoenix?

Each dot is one of Phoenix’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). Phoenix’s own 5.7 claims/patent is at or below the 16.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Phoenix's grants concentrate

Phoenix Electric Co., Ltd. is a focused PatentsView assignee: 22 CPC subclasses with 36.4% of grants classified under H01J (Electric Discharge Tubes OR Discharge Lamps). Peak complete grant year is 2015 (4 grants) versus a trough of 1 in 2016. By volume, Phoenix sits between Otto Männer Innovation GmbH and Prophesee.

Phoenix's three-year grant acceleration

Phoenix Electric Co., Ltd. shows 6 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.
