What this shows Span's Innovation Score is 30.8/100 (35th 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 Span?

Each dot is one of Span’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). Span’s own 16.1 claims/patent is ABOVE the 15.9 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Span's grants concentrate

Span Tech LLC is a focused PatentsView assignee: 2 CPC subclasses with 83.3% of grants classified under B65G (Transport OR Storage Devices, e.g. Conveyors FOR Loading OR Tipping, Shop Conveyor Systems OR Pneumatic Tube Conveyors). Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2024. By volume, Span sits between SK Enpulse Co., Ltd. and Star Mesh LLC.

Span's three-year grant acceleration

Span Tech LLC shows 6 grants in 2022–2024 against only 8 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.
