What this shows Proto's Innovation Score is 54.4/100 (top 8% 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 Proto?

Each dot is one of Proto’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). Proto’s own 18.1 claims/patent is ABOVE the 14.1 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Proto's grants concentrate

Proto Labs, Inc. is a focused PatentsView assignee: 17 CPC subclasses with 53.3% of grants classified under G05B (Control OR Regulating Systems IN GENERAL; Functional Elements OF Such SYSTEMS; Monitoring OR Testing Arrangements FOR Such Systems OR Elements). Peak complete grant year is 2023 (12 grants) versus a trough of 1 in 2018. By volume, Proto sits between Polytex Fibers LLC and Recensmedical, Inc..

Proto's three-year grant acceleration

Proto Labs, Inc. shows 18 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.
