What this shows Plexus's Innovation Score is 38.6/100 (top 40% 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 Plexus?

Each dot is one of Plexus’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). Plexus’s own 22.5 claims/patent is ABOVE the 8.7 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Plexus's grants concentrate

Plexus Holdings PLC is a focused PatentsView assignee: 2 CPC subclasses with 100% of grants classified under E21B (Earth OR Rock DRILLING; Obtaining OIL, GAS, Water, Soluble OR Meltable Materials OR A Slurry OF Minerals From Wells). Peak complete grant year is 2016 (2 grants) versus a trough of 1 in 2015. By volume, Plexus sits between Plastic Safety Systems, Inc. and Pocket Naloxone Corp..

Plexus's three-year grant acceleration

Plexus Holdings PLC shows 2 grants in 2022–2024 against only 1 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.
