What this shows Zogenix's Innovation Score is 36.1/100 (top 47% 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 Zogenix?

Each dot is one of Zogenix’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). Zogenix’s own 14.7 claims/patent is ABOVE the 14.4 median for these volume peers. More thorough claims than most filers at this scale, not just more of them.

Where Zogenix's grants concentrate

Zogenix International Limited is a focused PatentsView assignee: 9 CPC subclasses with 90.5% of grants classified under A61P (Specific Therapeutic Activity OF Chemical Compounds OR Medicinal Preparations). Peak complete grant year is 2023 (6 grants) versus a trough of 1 in 2024. By volume, Zogenix sits between Zapata Computing, Inc. and 2BC Innovations, LLC.

Zogenix's three-year grant acceleration

Zogenix International Limited shows 10 grants in 2022–2024 against only 11 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.
