What this shows Siga's Innovation Score is 32.1/100 (40th 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 Siga?

Each dot is one of Siga’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). Siga’s own 12.1 claims/patent is ABOVE the 5.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Siga's grants concentrate

Siga Technologies, Inc. is a focused PatentsView assignee: 8 CPC subclasses with 80.6% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2018 (9 grants) versus a trough of 1 in 2021. By volume, Siga sits between Shenzhen Fanpuguizhen E-Commerce Co., Ltd. and Starmark Pet Products, Inc..

Siga's three-year grant acceleration

Siga Technologies, Inc. shows 3 grants in 2022–2024 against only 7 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.
