What this shows Plex's Innovation Score is 25.9/100 (19th 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 Plex?

Each dot is one of Plex’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). Plex’s own 12.4 claims/patent is ABOVE the 11.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Plex's grants concentrate

Plex Corporation is a focused PatentsView assignee: 6 CPC subclasses with 50% of grants classified under H05G (X-ray Technique). Peak complete grant year is 2017 (2 grants) versus a trough of 1 in 2015. By volume, Plex sits between Plasma-therm NES LLC and Polymatech Japan Co., Ltd..

Plex's three-year grant acceleration

Plex Corporation shows 1 grants in 2022–2024 against only 3 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.
