What this shows PDSI's Innovation Score is 12.2/100 (2nd 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 PDSI?

Each dot is one of PDSI’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). PDSI’s own 1.0 claims/patent is at or below the 14.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where PDSI's grants concentrate

PDSI is a focused PatentsView assignee: 0 CPC subclasses . Peak complete grant year is 2017 (4 grants) versus a trough of 1 in 2018. By volume, PDSI sits between Orpyx Medical Technologies Inc. and Prime Polymer Co., Ltd..

PDSI's three-year grant acceleration

PDSI shows 1 grants in 2022–2024 against only 7 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.
