What this shows Persyst's Innovation Score is 30.7/100 (35th 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 Persyst?

Each dot is one of Persyst’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). Persyst’s own 5.0 claims/patent is at or below the 16.0 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Persyst's grants concentrate

Persyst Development Corporation is a focused PatentsView assignee: 3 CPC subclasses with 100% of grants classified under A61B (DIAGNOSIS; SURGERY; Identification). Peak complete grant year is 2022 (3 grants) versus a trough of 1 in 2016. By volume, Persyst sits between Perfect Form Manufacturing LLC and Piana Nonwovens LLC.

Persyst's three-year grant acceleration

Persyst Development Corporation shows 4 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.
