Does more volume mean deeper claims for Signature?

Each dot is one of Signature’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). Signature’s own 37.3 claims/patent is ABOVE the 18.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Signature's grants concentrate

Signature Therapeutics, Inc. is a focused PatentsView assignee: 7 CPC subclasses with 92.3% of grants classified under A61K (Preparations FOR Medical, Dental OR Toiletry Purposes). Peak complete grant year is 2015 (5 grants) versus a trough of 1 in 2018. By volume, Signature sits between SiCrystal GMBH and Skavis Corporation.

Signature's three-year grant acceleration

Signature Therapeutics, Inc. shows 1 grants in 2022–2024 against only 1 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.
