Does more volume mean deeper claims for Blackline?
Each dot is one of Blackline’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). Blackline’s own 17.0 claims/patent is ABOVE the 12.8 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Blackline's grants concentrate
Blackline Safety Corp. is a focused PatentsView assignee: 5 CPC subclasses with 66.7% of grants classified under G08B (Signalling OR Calling SYSTEMS; Order TELEGRAPHS; Alarm Systems). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2019. By volume, Blackline sits between BK Medical Holding Company, Inc. and Blue Green Works LLC.
Blackline's three-year grant acceleration
Blackline Safety Corp. shows 2 grants in 2022–2024 against only 3 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.
