What this shows PLK's Innovation Score is 29.0/100 (29th 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 PLK?

Each dot is one of PLK’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). PLK’s own 12.5 claims/patent is at or below the 13.2 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.
