What this shows Polycorp's Innovation Score is 29.5/100 (31st 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 Polycorp?

Each dot is one of Polycorp’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). Polycorp’s own 11.7 claims/patent is at or below the 13.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Polycorp's grants concentrate

Polycorp Ltd. is a focused PatentsView assignee: 6 CPC subclasses with 42.9% of grants classified under B02C (Crushing, Pulverising, OR Disintegrating IN GENERAL; Milling Grain). Peak complete grant year is 2019 (4 grants) versus a trough of 1 in 2016. By volume, Polycorp sits between PlayMakar, Inc. and Potrero Medical, Inc..

Polycorp's three-year grant acceleration

Polycorp Ltd. shows 4 grants in 2022–2024 against only 6 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.
