What this shows Plum's Innovation Score is 29.9/100 (32nd 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 Plum?

Each dot is one of Plum’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). Plum’s own 17.7 claims/patent is ABOVE the 17.5 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Plum's grants concentrate

Plum Laboratories, Inc. is a focused PatentsView assignee: 5 CPC subclasses with 73.3% of grants classified under H01Q (Antennas, i.e. Radio Aerials). Peak complete grant year is 2019 (6 grants) versus a trough of 1 in 2018. By volume, Plum sits between Phillips Medical, LLC and Polymer Solutions International Inc..

Plum's three-year grant acceleration

Plum Laboratories, Inc. shows 3 grants in 2022–2024 against only 11 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.
