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 18.9 claims/patent is ABOVE the 16.1 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 Systems Group, LLC is a focused PatentsView assignee: 8 CPC subclasses with 26.7% of grants classified under E01C (Construction OF, OR Surfaces FOR, Roads, Sports Grounds, OR THE LIKE; Machines OR Auxiliary Tools FOR Construction OR Repair). Peak complete grant year is 2020 (4 grants) versus a trough of 1 in 2016. By volume, Signature sits between Shenzhen Lescolton Electrical Appliance Co., Ltd. and Singular Computing LLC.

Signature's three-year grant acceleration

Signature Systems Group, LLC shows 1 grants in 2022–2024 against only 9 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.
