Does more volume mean deeper claims for Princeton?

Each dot is one of Princeton’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). Princeton’s own 17.0 claims/patent is at or below the 17.7 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Princeton's grants concentrate

Princeton Drug Discovery, Inc is a focused PatentsView assignee: 4 CPC subclasses with 100% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2018 (2 grants) versus a trough of 1 in 2020. By volume, Princeton sits between Pride Family Brands, Inc. and Pro-Gard Products LLC.

Princeton's three-year grant acceleration

Princeton Drug Discovery, Inc shows 1 grants in 2022–2024 against only 3 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.
