What this shows Primex's Innovation Score is 31.2/100 (37th 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 Primex?

Each dot is one of Primex’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). Primex’s own 12.0 claims/patent is ABOVE the 10.6 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Primex's grants concentrate

Primex EHF is a focused PatentsView assignee: 10 CPC subclasses with 80% of grants classified under C08L (Compositions OF Macromolecular Compounds). By volume, Primex sits between Prima Industrie S.P.A and Prism Pharma Co., Ltd..

Primex's three-year grant acceleration

Primex EHF shows 2 grants in 2022–2024 against only 2 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.
