What this shows Seari's Innovation Score is 28.9/100 (29th percentile 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 Seari?

Each dot is one of Seari’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). Seari’s own 10.8 claims/patent is ABOVE the 10.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Seari's grants concentrate

Seari Electric Technology Co., Ltd. is a focused PatentsView assignee: 9 CPC subclasses with 92% of grants classified under H01H (Electric SWITCHES; RELAYS; SELECTORS; Emergency Protective Devices). Peak complete grant year is 2019 (9 grants) versus a trough of 1 in 2015. By volume, Seari sits between Saga University and Shenzhen S-hande Technology Co., Ltd..

Seari's three-year grant acceleration

Seari Electric Technology Co., Ltd. shows 1 grants in 2022–2024 against only 13 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.
