Does more volume mean deeper claims for PSJ?
Each dot is one of PSJ’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). PSJ’s own 12.4 claims/patent is at or below the 15.1 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
Where PSJ's grants concentrate
PSJ International Ltd. is a focused PatentsView assignee: 19 CPC subclasses with 62.5% of grants classified under G01S (Radio DIRECTION-FINDING; Radio NAVIGATION; Determining Distance OR Velocity BY USE OF Radio WAVES; Locating OR Presence-detecting BY USE OF THE Reflection OR Reradiation OF Radio WAVES; Analogous Arra). Peak complete grant year is 2023 (5 grants) versus a trough of 1 in 2019. By volume, PSJ sits between Prada S.A. and Palatin Technologies, Inc..
PSJ's three-year grant acceleration
PSJ International Ltd. shows 7 grants in 2022–2024 against only 5 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.
