What this shows SI's Innovation Score is 48.3/100 (top 17% 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 SI?

Each dot is one of SI’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). SI’s own 18.3 claims/patent is ABOVE the 12.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where SI's grants concentrate

SI Group, Inc. is a focused PatentsView assignee: 25 CPC subclasses with 64.3% of grants classified under C08G (Macromolecular Compounds Obtained Otherwise Than BY Reactions Only Involving Unsaturated Carbon-to-carbon Bonds). Peak complete grant year is 2017 (7 grants) versus a trough of 2 in 2019. By volume, SI sits between SDB IP Holdings, LLC and San Jamar, Inc..

SI's three-year grant acceleration

SI Group, Inc. shows 14 grants in 2022–2024 against only 14 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.
