Where PST's grants concentrate

PST Inc. is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). By volume, PST sits between PS Industries Incorporated and Ptmc Institute.

PST's three-year grant acceleration

PST Inc. shows 1 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.
