Does more volume mean deeper claims for Signifier?
Each dot is one of Signifier’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). Signifier’s own 17.0 claims/patent is ABOVE the 14.0 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.
Where Signifier's grants concentrate
Signifier Medical Technologies Limited is a focused PatentsView assignee: 4 CPC subclasses with 85.7% of grants classified under A61N (ELECTROTHERAPY; MAGNETOTHERAPY; Radiation THERAPY; Ultrasound Therapy). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2024. By volume, Signifier sits between Siemens Mobility SAS and Silicon Power Computer & Communications Inc..
Signifier's three-year grant acceleration
Signifier Medical Technologies Limited shows 3 grants in 2022–2024 against only 2 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.
