What this shows Southwall's Innovation Score is 31.8/100 (39th 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 Southwall?

Each dot is one of Southwall’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). Southwall’s own 17.8 claims/patent is ABOVE the 10.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Southwall's grants concentrate

Southwall Technologies Inc. is a focused PatentsView assignee: 13 CPC subclasses with 66.7% of grants classified under G02B (Optical Elements, Systems OR Apparatus). Peak complete grant year is 2019 (2 grants) versus a trough of 1 in 2018. By volume, Southwall sits between Sotero, Inc. and Span-America Medical Systems, Inc..

Southwall's three-year grant acceleration

Southwall Technologies Inc. shows 1 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.
