What this shows Solugen's Innovation Score is 36.2/100 (top 47% 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 Solugen?

Each dot is one of Solugen’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). Solugen’s own 19.3 claims/patent is ABOVE the 11.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Solugen's grants concentrate

Solugen, Inc. is a focused PatentsView assignee: 16 CPC subclasses with 42.9% of grants classified under B01D (Separation). Peak complete grant year is 2021 (2 grants) versus a trough of 1 in 2024. By volume, Solugen sits between Softwheel Ltd. and Soundbite Communications, Inc..

Solugen's three-year grant acceleration

Solugen, Inc. shows 1 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.
