What this shows Sunflower's Innovation Score is 41.6/100 (top 33% 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 Sunflower?

Each dot is one of Sunflower’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). Sunflower’s own 22.8 claims/patent is ABOVE the 5.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Sunflower's grants concentrate

Sunflower Labs Inc. is a focused PatentsView assignee: 15 CPC subclasses with 62.5% of grants classified under B64U (Unmanned Aerial Vehicles [UAV]; Equipment Therefor). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2021. By volume, Sunflower sits between Sumitomo Forestry Co., Ltd. and Surana Brothers IP Holdings Limited.

Sunflower's three-year grant acceleration

Sunflower Labs Inc. shows 3 grants in 2022–2024 against only 3 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.
