What this shows Spectrum's Innovation Score is 51.6/100 (top 11% 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 Spectrum?

Each dot is one of Spectrum’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). Spectrum’s own 15.1 claims/patent is ABOVE the 14.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Spectrum's grants concentrate

Spectrum Pharmaceuticals, Inc. is a focused PatentsView assignee: 13 CPC subclasses with 100% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2015 (3 grants) versus a trough of 1 in 2018. By volume, Spectrum sits between Smartwash Solutions, LLC and SPX Fitness, Inc..

Spectrum's three-year grant acceleration

Spectrum Pharmaceuticals, Inc. shows 4 grants in 2022–2024 against only 0 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.
