What this shows Quidel's Innovation Score is 40.9/100 (top 34% 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 Quidel?

Each dot is one of Quidel’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). Quidel’s own 16.5 claims/patent is ABOVE the 12.3 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Quidel's grants concentrate

Quidel Corporation is a focused PatentsView assignee: 16 CPC subclasses with 93.8% of grants classified under G01N (Investigating OR Analysing Materials BY Determining Their Chemical OR Physical Properties). Peak complete grant year is 2019 (7 grants) versus a trough of 1 in 2016. By volume, Quidel sits between Prolitec Inc. and Rieke Packaging Systems Limited.

Quidel's three-year grant acceleration

Quidel Corporation shows 10 grants in 2022–2024 against only 14 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.
