What this shows Seed's Innovation Score is 34.7/100 (49th 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 Seed?

Each dot is one of Seed’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). Seed’s own 7.0 claims/patent is at or below the 9.6 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Seed's grants concentrate

Seed Co., Ltd. is a focused PatentsView assignee: 19 CPC subclasses with 50% of grants classified under G02C (SPECTACLES; Sunglasses OR Goggles Insofar AS They Have THE Same Features AS SPECTACLES; Contact Lenses). Peak complete grant year is 2020 (3 grants) versus a trough of 2 in 2015. By volume, Seed sits between Scott & White Healthcare and Shenzhen Bling Lighting Technologies Co., Ltd.

Seed's three-year grant acceleration

Seed Co., Ltd. shows 4 grants in 2022–2024 against only 5 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.
