What this shows Polyphor's Innovation Score is 33.5/100 (45th 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 Polyphor?

Each dot is one of Polyphor’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). Polyphor’s own 13.0 claims/patent is at or below the 14.3 median for these volume peers. Volume here does not track with deeper claims; several lower-volume peers claim more thoroughly per patent.

Where Polyphor's grants concentrate

Polyphor AG is a focused PatentsView assignee: 8 CPC subclasses with 97.6% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2017 (10 grants) versus a trough of 2 in 2023. By volume, Polyphor sits between Omega Ophthalmics LLC and Queen Mary University OF London.

Polyphor's three-year grant acceleration

Polyphor AG shows 5 grants in 2022–2024 against only 12 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.
