What this shows PHD's Innovation Score is 44.7/100 (top 25% 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 PHD?

Each dot is one of PHD’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). PHD’s own 13.9 claims/patent is at or below the 14.9 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where PHD's grants concentrate

PHD, Inc. is a focused PatentsView assignee: 20 CPC subclasses with 55% of grants classified under B25J (MANIPULATORS; Chambers Provided With Manipulation Devices). Peak complete grant year is 2018 (4 grants) versus a trough of 2 in 2015. By volume, PHD sits between Paris Sciences ET Lettres - Quartier Latin and Pola Pharma Inc..

PHD's three-year grant acceleration

PHD, Inc. shows 6 grants in 2022–2024 against only 4 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.
