What this shows Photo's Innovation Score is 25.5/100 (18th 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 Photo?

Each dot is one of Photo’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). Photo’s own 15.0 claims/patent is at or below the 15.8 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Photo's grants concentrate

Photo Diagnostic Systems, Inc. is a focused PatentsView assignee: 6 CPC subclasses with 60% of grants classified under G01V (GEOPHYSICS; Gravitational MEASUREMENTS; Detecting Masses OR OBJECTS; Tags). Peak complete grant year is 2020 (2 grants) versus a trough of 1 in 2019. By volume, Photo sits between Phoenix Conveyor Belt Systems GmbH and Picard Healthcare Technology (Dongguan) Co. Ltd..

Photo's three-year grant acceleration

Photo Diagnostic Systems, Inc. shows 1 grants in 2022–2024 against only 4 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.
