What this shows PST's Innovation Score is 20.2/100 (7th percentile of the PatentsView-derived corpus). The chart places that score against the nearest Innovation Score peers plus corpus poles, not a reprint of the volume ranking.

Does more volume mean deeper claims for PST?

Each dot is one of PST’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). PST’s own 7.6 claims/patent is at or below the 14.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

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.
