What this shows SOL's Innovation Score is 46.7/100 (top 20% 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 SOL?

Each dot is one of SOL’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). SOL’s own 13.3 claims/patent is at or below the 14.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where SOL's grants concentrate

SOL Inc. is a focused PatentsView assignee: 10 CPC subclasses with 100% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2024 (4 grants) versus a trough of 2 in 2021. By volume, SOL sits between Smpl Inc and Sonicedge Ltd..

SOL's three-year grant acceleration

SOL Inc. shows 6 grants in 2022–2024 against only 2 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.
