What this shows SEA's Innovation Score is 52.3/100 (top 10% 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 SEA?

Each dot is one of SEA’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). SEA’s own 8.5 claims/patent is at or below the 18.5 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where SEA's grants concentrate

SEA Sonic Electronics Co., Ltd. is a focused PatentsView assignee: 21 CPC subclasses with 39.1% 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 (6 grants) versus a trough of 1 in 2018. By volume, SEA sits between Saint-gobain Cristaux ET Detecteurs and Shandong Yingxin Computer Technologies Co., Ltd..

SEA's three-year grant acceleration

SEA Sonic Electronics Co., Ltd. shows 13 grants in 2022–2024 against only 4 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.
